Обсуждение вопросов повышения срока службы валков на стане горячей прокатки с шириной валков 1450 мм; технология валков
Description: The roll is one of the important parts of the rolling mill. In the rolling production process, the roll directly contacts the billet and deforms it with a certain pressure to roll various specifications of steel. The rolls work in the harsh environment of high temperature, high pressure, high speed accompanied by alternating cold […]
Optimizing the rolling and annealing process to improve the quality of cold-rolled products
Description: Laiwu Steel’s cold rolling production line is composed of a pickling line, two single-stand cold rolling mills, 24 bell annealing furnaces, a four-roll leveling line and a tension leveling line. The cold-rolling production line is mainly used for pickling hot-rolled strips of electrical steel, ordinary carbon steel, and low-alloy high-quality steel with a thickness […]
Новый процесс отжига и травления холоднокатаной нержавеющей стали и его преимущества
Desicrption: This paper mainly describes the cold rolling pickling process technology and its advantages.
