Gallium – IMCR Technology For Long Products, Plates and Narrow Width Flat Products
Gallium offers innovative technology for manufacturing long products from primarily scrap based plants integrating high speed caster and a rolling mill. This technology is applicable to both Billet Based Rolling and Slab based rolling to achieve finished products by significantly reducing costs and improving output quality preventing material yield losses.
Currently, most steel is continuously cast into slabs, billets or blooms, which have to be reheated when later rolling them into final shape. Gallium ICRT integrates the casting and hot-rolling of steel into one step, thereby reducing the need to reheat the steel before rolling it.
Depending on the product end-use, various shapes can be cast. The melting/casting/rolling processes are linked which substantially conforms to the finished product.
Gallium - Skin Pass Mill
(Six High Cold of Two Stands Pinch Pass Mill of Hydraulic AGC System)
Gallium skin-pass mills include full compliance with tight strip elongation tolerances, excellent flatness performance, high surface quality with respect to roughness, peak count and residuals and the availability of wet and dry skin-passing modes.
Gallium supplies stand-alone and inline skin-pass mills in either single or two stand design for adjusting the final mechanical properties, flatness and surface finish of cold-rolled strip. Due to its higher rolling forces and torques, a two-stand skin-pass mill is the preferred solution to meet the increasing demands placed on strip flatness, elongation and roughness, especially for hard-material grades. It consists of two series of two rollers and four rollers. It is used for leveling annealed cold rolling strips for improving machinery functions to enhance the surface hardness, strength and elasticity of CR strips.
Meanwhile, the CR strips through the leveler unit can have functions of excellent deep punching, shapes and surface clearness. Four rollers leveler unit for middle and wider coils and plates is equipped with hydraulic AGC pressing down and automatic adjusting rolling elevation lever installations.
Gallium Cold Rolling
Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for use in high-stress applications. Better surface finishes: Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.
Gallium Hot Rolling
Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.
