Hot Rolling Oil for Steel Plants -A Case Study

摘要

A hot rolling oil was successfully developed in authors laboratory which was successfully commercialized in Indian Steel Plant. Hot Rolling Oil A is useful in improving productivity of the mill and life of rolls Regular use of Hot Rolling Oil A at the six finishing stand of Hot Strip Mill has demonstrated achievement of following benefits: (a) Reduction in roll force and power by around 6-10%, helping in rolling of steels in critical sizes. (b) Reduction in average specific off-take of work rolls by 24.0%. (c) Reduction in specific consumption of work rolls by average 14.0%. The above benefits have been achieved at specific oil consumption level of 77.10 ml/ton of production. Good correlation observed between laboratory results and plant rolling parameters
