随着科学技术的不断发展,近年来我国冶金行业从国外引进一些新型的高速轧机,国内的一些重型机器厂也尝试生产高速轧机。对于高速轧机,如何保证在稳速轧制下的张力精度,如何保证有正确的动补偿量,关键在于如何得到精确的卷径,它是实现高速、稳定轧制的关键之一。特别是生产大卷 With the continuous development of science and technology, in recent years, China’s metallurgical industry introduced some new high-speed rolling mills from abroad. Some domestic heavy machinery factories also tried to produce high-speed rolling mills. For high speed rolling mill, how to ensure the tension precision under steady rolling and how to ensure the correct dynamic compensation, the key lies in how to get accurate roll diameter, which is one of the keys to realize high speed and stable rolling. Especially the production of large volumes
