Magnetic Billet Crane for Round & Square Billet Handling
Electromagnetic Overhead Cranes & Gantry Cranes for Handling Types of Ingots & Billets

A steel bloom and billet crane is a highly maneuverable electric overhead crane that moves large pieces of hot, soft metal from the melt shop to its next destination. Because the melt shop is so dangerous, it is normally located away from the other manufacturing working sites. The overhead crane feeds steel blooms and billets onto shaping rollers, transports the metal to be reheated in another furnace before shaping, transports the shaped steel to another conveyor for further processing, or delivers it to a storage location.

A steel bloom or billet crane is designed to transfer heavy loads rapidly and safely from the melt shop to the rolling mill to storage. To address the issues of handling either hot and soft metal or cooler pieces, the travelling crane employs a number of Smart Features including as Sway Control, Slack Rope Prevention, and Target Positioning, which enable operators to accomplish complex operations with ease.It can be customized to your specifications, all the way up to full automation.

Steel billet

What is steel billet ? Steel billet is a term used to describe freshly manufactured steel that is still in the shape of a rectangle or a metal bar. The billet steel needs to be processed into more useful pieces before it can be sold on the market. Raw steel is useless in its raw form, so it must be cast into the desired shape.

Billets (also known as ingots) are not usable until they are shaped into more practical forms and sizes. Although they have been heated in steel furnaces, they still require a series of molding and shaping operations such as cold and hot process, milling and cutting before being sold in shops or used for diverse applications.

Magnetic billet cranes for round billet / bar handling

Steel bloom and round billet are semi-finished steel products made by rolling ingots or continuous castings through a series of rollers to reduce their thickness, width, and length. As a result, the name "bloom" refers to a long bar with a cross-section that resembles a flower. It can then be formed into shapes like circular bars and squares. Steel blanks are often utilized in applications that require strength, toughness, and flexibility. Steel blooms are semi-finished products made from ingots, billets, or steel blooms. Blooms have a rough surface and are often rectangular or square. They are utilized in the manufacturing of forged objects such as railway wheels and axles.

Magnetic billet cranes for square billet

A square billet is a form of semi-finished steel product created by hot rolling or extrusion. In contrast to blooms, billets are typically square or rectangular in shape with uniform lengths along their length. They are utilized in applications where strength and durability are required but ductility is not, such as structural components such as I-beams or other massive constructions. A billet is a semi-finished steel product cast in the shape of a rectangle or square. Billets have a smooth surface and are used to make items like bars, rods, and pipes.
