摘要
介绍了采用半连轧工艺生产工字钢的工艺流程,根据现有连轧生产设备和工艺,对孔型系统进行了优化设计,将扩腰孔型应用到连轧工艺中,在同一套孔型中仅更换3个孔即可轧制不同规格的工字钢,降低了企业生产成本,增加了企业竞争力。
The semi-continuous rolling process for I-beam section was introduced.According to the existing rolling production equipment and process,the pass system design was optimized.The expanding waist pass was applied to continuous rolling process.Under the condition that only three passes were replaced in the same set pass system,the different specifications of I-beam section were rolled.The production cost was reduced,and the competitiveness of enterprises was increased.
