Overhead cranes designed for steel processing & steel service centers, i.e, ladle crane, billet crane, coil handling crane, slab handling crane & eot crane.
Application Fields;Steelworks and foundries, Rolling mills, Storage and staging
The demand for iron, steel, aluminum, and copper has expanded dramatically as a result of the worldwide economic boom. Material handling equipment is required in scrap yards, steel mills, rolling mills, and electrolytic metallurgical operations. The most important factor is reliability, because any unplanned downtime will result in scrap and lower output.
Charge and ladle handling cranes in steel factories must be able to work around furnaces and molten steel at temperatures above 70°C. Cranes for handling iron bars, billets, and coils move at high speeds, precisely positioning and rotating loads. Finally, common electrical components will deteriorate in the environment around electrolytic metallurgy and electroplating lines.
Steelworks, Electric Arc Furnaces (EAFs), and Rolling mills are the three main types of facilities used to produce very big molten steel chunks or rolled steel.
Process overhead cranes are designed for safely and reliably operation and for heavy-duty material handling in steel mills.
Overhead cranes for steel mills are typically produced under special specifications. A variety of specifications have been set for the design of these process overhead cranes by iron and steel experts.
This type of steel mill overhead crane generally includes:
Based on the working duty, the steel mill overhead cranes are also can be grouped into heavy duty, intermediate duty & light overhead crane.
Some steel mills also make the following division:
The under-hook attachments can be driven mechanically, electromagnetically, electro-hydraulically, or both.
The steel making and continuous casting processes rely heavily on the casting bridge crane. It is primarily used to feed molten iron into the converter; to lift the molten steel ladle to the refining furnace on the refining bay or to the continuous casting ladle turret on the molten steel receiving bay.
Main feartures of casting overhead crane
Main characteristics include high safety, a high working level (A7A8), and a harsh working environment (high temperature, dusty).
Casting cranes are classified into five types based on their overall structure: four-beam and four-track double trolley type, four-beam and six-track double trolley type, double-beam and double-track single trolley type, double-beam four-track double trolley type, and double-beam and double-track combined trolley. We called it QDY metallurgy overhead crane for capacities less than 75 tons, and YZ metallurgy overhead crane for capacities greater than 75 tons.
Main type sof casting overhead crane
Our casting crane is distinguished by its novel structure, safety and dependability, economy and durability, and ease of maintenance. We can also offer the following options:
Grab cranes are useful in metallurgy, building materials, the chemical industry, coal mining, and other industries. It loads and unloads ore, slag, coke, coal, sand, and other bulk materials in the workshop, warehouse, or open air. We have two types of grab cranes in our Overhead Bridge Crane Factory: the General QZ grab overhead crane and the garbage grab overhead crane. The crane manufacturer can supply you with a single girder grab crane, a double girder grab bridge crane, and any customized grab bucket crane for your warehouse application.
Main features of grab overhead crane
The bridge frame, crane traveling mechanism, trolley, and electrical equipment are the main components of the QD model double-girder bridge crane. It is appropriate for machining workshop, auxiliary workshop of metallurgical plant, warehouse, stockyard, power station, and other operations; it is also appropriate for production workshops in the textile, chemical, and food industries. Its working level is classified as light, medium, or heavy depending on the frequency of use. The working temperature range is -25°C to 40°C, and it is not supposed to be used in flammable, explosive, or corrosive media environments.
The girder structure, crane travel device, and trolley with lifting and moving device comprise the LDY model foundry overhead crane. On the main girder, there are rails for the hoist trolley to move. The heat insulation device is installed beneath the electric hoist. The main girder joint is connected to the two side end carriages by a joint point in the middle.
In the steel mill/metallurgy industry, for light weight ladle handling, a ldy single girder overhead crane is a cost-effective solution. The LDY single girder ladle crane is specially designed to lift hot small ladles. The working temperature could reach 60 degrees.
The single girder ladle crane material has good resistant to high temperatures. And electrical components will be outfitted with a cooler fan. For cabin control, the motors are H class, cooler, and insulated.
The crane has a detachable electric disk, which is especially suitable for metallurgical factories to load and unload or transport ferrous metal products and materials with magnetic permeability such as steel ingots, section steel, pig iron blocks, scrap iron, and scrap steel in fixed bays indoors or in the open air. It is also commonly used in machinery factories and warehouses to carry materials such as steel, iron blocks, scrap iron, scrap steel, iron filings and so on.
The overhead crane is equipped with an detachable electric disk or chuck, which is ideal for loading and unloading ferrous metal products and materials which are with magnetic permeability such as steel ingots, section steel, pig iron blocks, scrap iron, and scrap steel in fixed bays indoors or outdoors. Steel, iron blocks, scrap iron, scrap steel, iron filings, and other materials are commonly transported in machinery factories and warehouses.
LDA Single Girder Overhead Cranes are commonly used to lift goods in plants, warehouses, and material stores. The equipment cannot be used in a combustible, explosive, or corrosive environment. A single girder overhead crane has a more reasonable structure and higher strength steel overall when used in conjunction with a CD, MD model electric hoist as a complete set. It is primarily used for maintenance in the metallurgy workshop.
A BZD type floor mounted jib crane is a type of light duty overhead crane that is used in conjunction with a wire rope electric hoist or an electric chain hoist. A column, slewing arm, slewing drive device, and electric hoist comprise the crane. Anchor bolts secure the column's bottom to the concrete foundation. The cycloidal pinwheel reduction device rotates the cantilever, and the electric hoist runs in a straight line left and right on the cantilever I-beam, lifting heavy objects.
Jib cranes are a new generation of light hoisting equipment designed to meet the demands of modern manufacturing. It is particularly well-suited to short-distance, frequent use, and intensive hoisting operations. It has high efficiency, energy savings, trouble saving, a small floor area, and is simple to operate and maintain.
For a range of applications in foundries, we have the correct crane solutions: casting cranes with up to four crane girders for safe and effective ladle handling. In-house transfer of casting components (e.g. mold boxes) and handling of the castings to be processed with double-girder overhead traveling cranes.
Scrap metal is a major raw material used in steel production. Steel mills can be reached by sea, rail, or road. When the scrap metal arrives at the scrapyard, the crane must reach into the transport vehicle and safely and quickly unload the metal. These unloading cranes must be dependable and efficient in order for transport vehicles to pass through the facility and waste to flow into the factory. Speed is critical: the faster the vehicle is unloaded, the sooner it can leave.
Sometimes there is more waste than can be processed immediately. It is frequently mixed and must be classified before smelting. You may have a large storage area, and your crane must be able to reach all areas of the area in order to obtain the necessary materials quickly. Bridge cranes are typically used to unload trains or road vehicles, sort materials, and load steel drums for loading into the furnace.
We recommend high-speed grab overhead cranes and high-speed electromagnetic cranes because waste is a difficult-to-handle material with no fixed hook or pliers shape. The claw grab can grab anything that can be bit with its teeth. The magnet attracts the entire metal sheet to its surface. Both types of cranes can adapt to your load type and site conditions, and they are outfitted with the level of automation that you require.
Steel production is a continuous process. The smelting workshop is a dangerous place with suffocating dust, hot metal, and open flames. The smelting shop crane must be capable of lifting and transporting liquid metal drums safely.
Manufacturing molten steel
Steel is made from two primary sources: iron ore raw materials and scrap. They are treated separately because they are different substances. In a direct reduction process, iron ore and coking coal are combined to produce solid metallic iron. The molten iron is lifted by the ladle crane and mixed with scrap to create molten steel.
An overhead crane loads scrap from the scrapyard into the furnace. The hopper is lifted to the melting furnace by the main lifting machinery. During loading, the auxiliary crane on the crane opens and closes the bucket. An alkaline oxygen furnace or an electric arc furnace can be used, depending on the equipment. Scrap is added to iron in large steel mills, but scrap may be the only original source of liquid metal in small steel mills.
Cast molding
A pouring crane assists in mixing the molten metal in the correct proportions from the initial blast furnace in the steelmaking process. The molten steel will be cast into shape once the mixing is complete. Tundish cranes are typically employed in tundish maintenance and handling.
Multifunctional crane
Loading cranes, ladle cranes, gate cranes, and tundish cranes are all very similar, and their names are determined by where they are located and what they do in the factory. They are typically bridge cranes outfitted with special attachments for lifting massive ladles filled with liquid metal. They typically serve multiple functions and serve as backups for one another. A waste charging and maintenance hoist, such as cleaning the empty ladle or lifting the furnace shell, can be added.
The smelting plant's slabs and billets are incandescent and ductile. They can be rolled into any shape needed using a rolling machine. This is sometimes done right away. They are sometimes placed in a storage area for later processing. from the casting to the rolling mill necessitates the use of a crane.
Move hot metal
Typically, the billet or slab crane is a highly maneuverable electric overhead (EOT) crane. The distance between the smelting workshop and the rolling area is considerable. It can transfer hot, soft metals from the casting area to the storage area if necessary. When necessary, it can also feed steel billets or slabs into the rolls. Perhaps the steel needs to be reheated in another furnace before it can continue to form. The formed steel can be transported by the same crane to another conveyor for further processing or to a storage area.
Suitable for load handling equipment of various shapes and sizes
Because of the variety of products and shapes that fall off the drum, the crane requires a special load handling device. Mechanical or hydraulic clamps can hold slabs in place, while magnets can hold slabs, billets, or coils in place, and C-hooks can lift coils and smaller billets. Because steel must be insulated and formed, there is some radiant heat, and the grab must be insulated.
Positioning aid
Each factory has a limited amount of floor space. A rotating trolley or lifting beam assists the operator in placing the steel more precisely on the conveyor that feeds the drum or storage area. Auxiliary cranes aid in the location of larger objects and maintenance tasks.
Storage and staging
Some steel products may be shipped immediately after leaving the production line, while others must be transported to storage facilities.
Electric overhead cranes (EOT) are typically installed above the main storage area in warehouses. These areas are not particularly hot or dusty, but they do require some thermal protection. Wall console cranes can be used in smaller facilities that do not have enough space for gantry or bridge cranes. These can also be used as auxiliary cranes in large-scale operations. Yuantai provides the lifting equipment needed for safe and efficient steel storage. We can help you improve the efficiency of your warehouse operations whether you operate a large steel warehouse, a small regional distribution office, or any organization in between.
Our EOT cranes can also be outfitted with a variety of smart features. Target positioning, sway control, and load floating, for example, not only shorten processing time but also reduce crane wear and tear, extending its service life.
