首钢高速线材厂φ6．5mm系列产品的工艺优化

The Process Optimization of φ6.5mm Series Product of Shougang High-Speed Wire Rod Plant

首钢高速线材厂通过优化工艺设计，解决了φ6．5mm系列产品尺寸精度差的问题，提高了产品质量，并通过预精轧机甩机架生产，减少了工装备件，缩短了换辊时间，提高了生产作业率，经济效益显著。

Through the optimization of process design, Shougang High-Speed Wire Rod Plant solves the poor dimensional accuracy problem and improves the product quality. Moreover, through reducing the roiling pass of pre-finishing mill, the consumption of spare parts of equipment is reduced, the rolls changing time is reduced, and the production efficiency is improved. The economic profit is obvious.
