一、前言 目前,国内65Mn之类钢带热处珲多用牵引式电炉组连续淬火、回火。淬火时用压模压紧钢带,喷射冷却液冷却,以防止钢带淬火变形,但不能达到预期的效果,存在着波浪、凹陷等变形问题,而且常发生拉槽、斑点、压印等表面缺陷。为此而作下列试验。 First, the preface At present, the domestic steel strip 65Mn heat 珲 multi-purpose traction electric furnace continuous quenching and tempering. During quenching, the steel strip is pressed and compressed by a compression die to cool the steel strip so as to prevent the steel strip from being quenched and deformed, but the desired effect is not achieved. Waves, dents and other deformation problems occur, and surface defects such as flutes, spots and embossings often occur . For this purpose, make the following test.
