Choose your crane for steelmaking

We know the hazards and challenges of the metals production industry: open flame, molten metal, severe heat, dangerous loads and continuous production demands. Our advanced lifting equipment, technologies and service can improve the safety and productivity of operations across every area of your plant.

Equipment for Metals Industry

• Double-girder ladle handling cranes: A ladle handling crane lifts large, open-topped cylindrical containers (ladles) filled with liquid metal to the basic oxygen furnace (BOF) for mixing. The raw materials of iron ore and coking coal are combined to produce solid metallic iron, and this iron added to scrap metal creates steel. The crane also transports the liquid iron or steel from the BOF and electric arc furnace to the continuous casting machine.
• Four-girder charging cranes: A charging crane is critical in steel production. To make steel, a charging crane feeds an electric arc furnace (EOF) in the charging bay and should be able to deliver hot metal to the turret station of a continuous casting machine (CCM) or the ladle furnace (LF). This is a heavy-duty, continuous operation. The same crane can be a backup for the ladle crane if needed. Charging cranes are sometimes called teeming cranes.
• Slab and billet handling cranes: A slab and billet crane is a highly maneuverable electric overhead traveling (EOT) crane that transports large pieces of hot, soft metal – also known as slabs and billets – from the melt shop to its next destination. Because it is so hazardous, the melt shop is usually some distance away from other production locations. The crane feeds the slabs and billets into shaping rollers, takes the metal to be reheated in another furnace before shaping, moves the steel that has been shaped to another conveyor for further processing or delivers it to a storage area.
• Coil and plate handling cranes: A coil and plate handling crane handles metal bars, plates, and coils during machining processes. They can be designed for both indoor and outdoor use. Due to the wide variety of materials they need to handle, such a crane can be fitted with a variety of lifting devices that change with the nature of the material.
• Scrap handling cranes:A scrap handling crane handles scrap metal in the scrapyard of a steel mill. Scrap arrives by sea, rail, or road, stays in the scrapyard until it can be processed, and eventually gets melted down by the smelter in a melt shop. Difficult to handle, scrap has no defined shape for a hook or tong to fit onto, and it is often mixed, so it requires sorting. A scrapyard crane has to fit the size of the vehicles that deliver the scrap and must be able to access the right materials quickly from all parts of the storage area.
• Overhead Cranes: In the metallurgical industry, bridge cranes are mainly used for lifting and transporting large metal materials and equipment. For example, in the rolling workshops of steel companies, bridge cranes can be used to lift billets, steel and other materials to assist in completing production processes such as rolling and shearing. In addition, bridge cranes can also be used to transport large smelting equipment, mechanical parts, etc.

Expertise for Metallurgical Industry

The reason why cranes are used in the metallurgical industry is that during the metallurgical production process, a large number of heavy objects need to be transported, transferred, and hoisted. These tasks require the use of various types of mechanical equipment such as cranes to complete. Cranes are widely used in the metallurgical industry. For example, in steel enterprises, they are used to lift heavy objects such as hot-rolled steel coils and plates, and assist in completing production processes such as cold rolling, straightening, and packaging. In the non-ferrous metal industry, it is used to lift molten metal, semi-finished products and finished products in smelting furnaces. In the building materials industry, it is used to lift cement, bricks, slates and other building materials.

The role of cranes in the metallurgical industry is to improve work efficiency and reduce workers’ labor intensity. However, there are certain safety risks when using cranes, so operators must be trained to understand the operating procedures and safety regulations of the equipment. During operation, it is necessary to maintain a stable operating state and prevent sudden acceleration, sudden braking, etc. to avoid equipment damage and casualties. In addition, equipment must be inspected and maintained regularly to ensure its normal operation and service life.

Application of 5 Ton Metallurgic Single girder Overhead Crane in Pakistan

We have many cooperation projects in Pakistan and can provide Pakistani customers with the best metallurgical crane solutions. Today we will explain to you the main features and design of this crane

LDY Single girder overhead crane is mainly used for lifting molten metal and foundries in metallurgy. The lifting hoist is YH metallurgy wire-rope electric hoist with lifting capacity reaching 10t. LDY electric single girder crane is a product developed on the basis of LD electric single girder overhead crane. It is used in conjunction with metallurgical electric hoist, which can meet the requirements of lifting molten metal. Its main girder rigidity and strength are designed in accordance with requirements of lifting melting metal.

The bottom of main girder adopts special heat-insulation treatment with working environment temperature ﹣10℃~﹢60℃, and relative humidity ≤ 50%( 40℃). Design and manufacture meet the requirements of AQSIQ Doc # (2007)375. LDY electric single girder overhead crane is suitable for factories, mines, power stations, warehouses and workshops. The control mode of the crane can be 2 types: ground pendant or remote control. This LDY single girder metallurgy overhead crane can be also employed to lift non-molten metal and high temperature solid metal.
