集装箱用特种槽钢的研制开发

Research and Development of Special Channel Steel for Container

为拓宽产品系列,济钢中型轧钢厂利用横列式轧机,150mm×150mm连铸方坯,12道次轧制,开发生产了集装箱用特种槽钢。通过优化设计关键道次的孔型、导卫、控冷、矫直及深加工工艺等,特别是K1孔设计采用了类直轧的闭口控制式孔型系统,降低了后续矫直压力和轧辊消耗。实践证明,开发的工艺可行,产品的力学性能、外形尺寸、表面质量等指标均能够满足企业标准及用户要求,成材率达到94.3%。

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%.
