随着我国冷轧事业的发展,对冷轧辊质量的要求越来越高。某些冷轧辊的质量不能满足使用要求,主要问题是使用寿命低,辊耗高,例如φ245×600×1235毫米的铝箔精轧机轧辊的质量问题曾在77年的冶金部机修热处理会议中提出。为此我厂在试制该辊时, With the development of cold rolling in China, the quality of cold roll is getting higher and higher. Some of the quality of cold roll can not meet the requirements of use, the main problem is the low life, high roll consumption, such as φ245 × 600 × 1235 mm quality of aluminum foil finishing mill roll in Machinery and Metallurgy in 77 years proposed heat treatment conference. To this end I plant in trial production of the roller,
