TP347H大规格厚壁管工艺优化探讨

Discussion on Process Optimization of TP347H Large Size and Thick-walled Tube

TP347HФ63mm×13mm大规格厚壁管市场需求量较大,在保证成品管材质量的前提下提高成材率是我公司提高边际利润的有效办法。本文探讨在LG90轧机新增Ф110/Ф 63mm孔型,一道次轧制大规格厚壁管材可行性。在实际生产中一道次出成品不仅提高了生产效率、降低了生产步骤费用、同时也大大的提高TP347H的成材率。

TP347H ofФ63 13mm large thick-walled tube large is great in market demand.It＇s an effective way to in-crease marginal benefit by improving the yield while the quality of finished tube is ensured.In this paper,the feasibility to add aФ110/Ф63 pass in LG90 mill for rolling large-sized and thick-walled tube at one pass was discussed.The production practice showed that producing finished product with at one pass not only improves the production efficiency and reduce the cost of production steps,but also greatly improve the yield of TP347H.
