介绍了工业纯钛(Gr.2)斜轧穿孔无缝管的生产试制情况,并对生产中遇到的问题进行分析,重点讨论斜轧管冷加工过程中Q值对管材内表面质量的影响及管材镗孔问题.结果表明:在进行斜轧管冷加工时,选取合适的Q值,并且在靠近成品的加工道次进行镗孔,不仅可以有效地去除内表面微裂纹,而且能够保证成品质量.
The preproduction situation of commercial pure titanium (Gr.2) cross-rolled boring seamless tube was introduced, and the problems in it were analyzed. The effect of Q value on tube inner surface quality and boring problems were discussed. Results show that the suitable Q value and boring in finished-product-near pass can eliminate inner surface micro-crack effectively and ensure quality of finished products.
