前言 在中口径钢药筒生产过程中,每次引伸前都必须进行再结晶退火,然后用硫酸洗去氧化皮并进行磷化和皂化。采用感应加热后,氧化皮虽较电炉加热减薄,但仍需酸洗,这样劳动条件差,劳动强度大,产品周转慢,要实现冲压联动化很困难。

Preface In the production process of medium caliber steel cartridge, recrystallization annealing must be performed before each extension, and then the scale is washed with sulfuric acid and phosphated and saponified. The use of induction heating, although the oxide skin thinner than the electric heating, but still need pickling, so poor working conditions, labor-intensive, slow product turnover, to achieve linkage stamping is very difficult.
