铁素体耐蚀钢主要用于制做食品机械制造业的冲压制品,所需钢材主要为冷轧薄板。由于铁素体耐蚀钢具有体心立方的晶体结构,因此,塑性变形对其机械性能影响很敏感。研究用钢是由黑色冶金中央科学研究所的实验场采用50kg 容量感应炉冶炼。重17kg的钢锭加热到1 100℃锻造开坯成薄板坯,薄板坯轧制成厚3.5 mm 的半成品,热轧半成品经880℃退火酸洗后冷轧成厚1.0 mm 冷轧板。冷轧板生产过程中,经3次中间退火和酸洗,中间退火酸洗后的厚度为3.4mm、1.35 mm 和1.0 mm,与之相应的设备压下量为75%、25%和0%。冷作硬化状态的板材加热到700℃～1
Ferritic corrosion-resistant steel is mainly used in the manufacture of food machinery manufacturing stamping products, mainly for cold-rolled steel sheet. Because ferritic corrosion-resistant steel has a body-centered cubic crystal structure, plastic deformation is very sensitive to its mechanical properties. The research steel is smelted by a 50 kg capacity induction furnace from the experimental site of the Central Research Institute of Black Metallurgy. The steel ingot weighing 17kg is heated to 1 100 ° C forging to form a thin slab, and the thin slab is rolled into a semi-finished product with a thickness of 3.5 mm. The semi-finished hot rolled semi-finished steel is annealed and pickled at 880 ° C and then cold rolled into a 1.0 mm thick cold rolled slab. Cold rolled sheet production process, after three intermediate annealing and pickling, intermediate annealing pickling thickness of 3.4mm, 1.35mm and 1.0mm, with the corresponding equipment reduction of 75%, 25% and 0% . Plate hardened state is heated to 700 ℃ ~ 1
