In order to reduce roll wear consumption and improve energy saving,a low temperature micro-lu-brication optimization process was established,and roll consumption tests were carried out on 2160 mm hot tandem rolling with seven stands.The transverse distribution of pressure between rolls under process lubri-cation was analyzed by field test,and the index parameters before and after low temperature micro-lubrica-tion optimization were compared.The results show that the thermal slip index is reduced by about 15%af-ter adding low temperature micro-lubrication technology compared with before lubrication optimization.The slip factor is reduced by about 13%.Roll consumption is reduced by about 18%.The low temperature mi-cro-lubrication optimization method in this paper effectively reduces the roll consumption,and then effective-ly avoids the skid phenomenon,and finally optimizes the strip outlet shape,realizing the energy saving ef-fect and greatly improving the quality of hot rolling.
