Research and Development of Special Channel Steel for Container
Abstract：In order to broaden the product range, The Medium Section Rolling Plant of Jinan Steel developed and produced special channel steel for container by open-train mill, 150 mm ×150 mm continuous casting billet and 12 passes. The groove of key pass, guide and controlled cooling, straightening and deep processing technologies were designed and optimized. Especially, the design of K1 pass used a vertical-like and closed control type pass system. The follow-up straightening pressure and roll consumption were reduced. Practices showed that developed processes are feasible, the mechanical properties, dimensions and surface quality of the products all meet the needs of the standard of the enterprise and users. The qualified product radio reached 94.3%.
