不锈钢毛管二次穿孔工艺的探讨

APPROACH TO SECONDARY PIERCING PROCESS OF STAINLESS STEEL SHELL

介绍了在φ100mm斜轧穿孔机上生产1Cr18Ni9Ti不锈钢毛管的二次穿孔工艺。该工艺比一次穿孔工艺生产的毛管壁更薄、外径更大,由此为减少冷轧道次,扩大品种创造了条件。

Introduced in the paper is the secondary piercing piocess of 1Cr18Ni9Ti stainless steel sheel with the φ100 cross-rolling piercer, which turns out the thinner wall and bigger O.D. of shell comparing with that of preliminary piercing process, thereby creating the conditions of reducing cold rolling pass and expanding the product variaties.
