In a metallurgical factory, cranes play a crucial role in various production processes. Here are the main applications:
Raw material handling: Metallurgical factories often deal with large quantities of raw materials such as iron ore, coal, and limestone. Cranes are used to unload these materials from transport vehicles and transfer them to storage areas. For example, grab cranes are commonly employed to scoop up bulk materials from train wagons or ships and deposit them in stockpiles.
Furnace charging: In the smelting process, cranes are essential for charging furnaces with raw materials and additives. They precisely lift and pour the required materials into the furnaces at the right time and in the correct amounts. This ensures a smooth and efficient smelting process. For instance, overhead cranes are used in steel mills to transport ladles filled with molten iron or other alloys to the furnace for further processing.
Molten metal handling: Handling molten metal is a critical and hazardous task in metallurgical factories. Cranes equipped with specialized ladles are used to transport molten metal from the smelting furnace to the casting area or other processing stations. These cranes must have high precision and reliability to prevent any spills or accidents. For example, in a copper smelting plant, cranes are used to transfer the molten copper to the casting machines for producing copper ingots.
Ingot and billet handling: After the molten metal is cast into ingots or billets, cranes are used to move them for further processing or storage. They can stack the ingots and billets neatly in the storage area and transport them to the rolling mills or other processing equipment as needed. For example, in an aluminum processing plant, cranes are used to handle aluminum ingots and transport them to the rolling mills for producing aluminum sheets and foils.
Equipment maintenance: Cranes are also indispensable for maintaining the various equipment in a metallurgical factory. They can lift heavy equipment components for repair, replacement, or installation. This helps to reduce the downtime of the production equipment and ensure the normal operation of the factory. For example, when a large – scale crusher in a metallurgical factory needs maintenance, a crane is used to lift its heavy parts for repair or replacement.
