在“红十月”工厂,耐热合金、不锈钢、高合金钢及结构钢板材在两台单架式四辊轧机上进行轧制。轧机采用9×2锻钢空心轧辊,其直径为370/90毫米,辊身长度为1600毫米,表面淬火层硬度不低于95H_ш。轧辊由乌拉尔及电钢城重型机器厂按同一技术条件供货。但在同样的生产条件下,两厂所供应的轧辊具有不同的寿命。前者的寿命完全满足要求,而后者的寿命很短,且不均匀。在绝大多数情况下,电钢城重机厂(Э3ТМ)所供应的轧辊是由于某些不同于
At the “Red October” plant, heat-resistant alloys, stainless steel, high-alloy steel and structural steel sheets were rolled on two single-stand four-roll mills. Mill with 9 × 2 forged steel hollow roll, the diameter of 370/90 mm, roll length of 1600 mm, surface hardness of not less than hardened 95H_ш. Roll from Ural and Electric Steel City heavy machinery factory under the same technical conditions of supply. However, under the same production conditions, the rolls supplied by the two plants have different lifetimes. The former fully meet the life expectancy, while the latter’s life is very short, and uneven. In the vast majority of cases, the rolls supplied by Electro-City Heavy Machinery (Э3ТМ) are due to some differences
