连轧中型生产线矫直机改造

REFORMATION OF STRAIGHTENER OF MEDIUM SECTION CONTINUOUS ROLLING LINE

介绍了宣钢连轧中型生产线矫直机改造情况。因800矫直机矫直能力不足,限制了更大规格、更高强度钢种产品及矿用U型钢的开发生产,技术人员根据连轧中型生产线工艺布置及设计品种的工艺要求,对矫直机改造提出技术要求。根据现场使用经验,自主设计了各规格矫直辊;在矫直机初步设计审查中,对矫直机部分结构提出改进方案,使矫直机更适用于现场工艺。通过矫直机改造,提高了矫直能力,增加了矫直产品规格,提高了产品产量和质量,满足了市场需求。

It is introduced the reformation of straightener of continuous medium section rolling line in Xuan Steel. Because of not enough straightening capacity, the 800 straightener limits the further development of steel grades with larger specification and higher strength as well as mine - using U - type steel. According to the process layout of continuous medium section rolling line and process requirement of designed grades, our technician proposed the reformation demand for the straightener. Based on the actual experiences, we design ourselves straightening rolls with various specifications; propose improving plan for part structure of straighte- ner in preliminary design examination to make the machine more suitable for site process. With the reforma- tion the straightening capacity is expanded, the products specification increased, output raised, quality im- proved, and the market requirement met.
