大棒线粗轧机孔型轧方坯生产实践

PRODUCTION PRACTICE OF PASS-ROLLED BILLET IN LARGE BAR AND WIRE ROUGHING MILL

为配合某钢厂高端线材和精品小棒产品开发,打通“二火”生产工艺流程,实现“二火材”生产,根据大棒线的现有工艺装备条件,在不改变设备工艺平面布置的情况下,对粗轧机孔型系统进行改造,实现了利用现有坯料开小方坯生产。

TIn order to cooperate with the development of high-end wire rods and high-quality small rod products of a steel plant,open up the"two fire"production process and realize the production of"two fire materials",according to the existing process and equipment conditions of the big rod line,without changing the equipment process plane In the case of layout,the pass system of the roughing mill was modified to realize the use of existing billets for billet production.
