按照不退火直接冷轧工艺,研究其在BJ4不锈钢生产中的应用。结果表明:BJ4热轧态冷轧技术上完全可行,但冷轧前几道次变形抗力比退火态高15~20%,具体工艺需要大生产轧机试制。
In accordance with the direct annealing without annealing process, to study the BJ4 stainless steel production. The results show that the BJ4 hot rolling cold rolling technology is completely feasible, but the first several passes of cold deformation before deformation are 15-20% higher than the annealing temperature. The specific process needs trial production of large production rolling mill.
