1991年,“一种轧辊小挠度、高刚度轧机”获专利,专利号:89101393.8,它引起众多报刊轰动宣传。但在设备运行过程中存在辊系润滑系统漏油严重、测厚仪精度不高、AGC控制系统精度不高,生产中经常出现轧辊轴承抱死和轧制钢带断带,一些部件加工精度偏低、标准化程度不高等问题,造成了冷轧机市场混乱,行业经济损失重大。国家知识产权局和多 In 1991, “a roll small deflection, high stiffness mill ” patented, patent number: 89101393.8, which caused a lot of press sensation. However, during the operation of the equipment, there are serious oil spills in the roller lubrication system, the precision of the gage is not high, the precision of the AGC control system is not high, and the bearing of the roller bearing is often locked and the strip of the rolled strip is broken during the operation. Low, the degree of standardization is not high, resulting in chaos in the cold rolling mill market, the industry suffered significant economic losses. State Intellectual Property Office and more
