Abstract
The article dwells upon the assessment of operation efficiency of lubricants supplying system through the whole finishing group at continuous broadband hot rolling mill “2000” Jointstock Venture Company “Magnitogorsk Iron and Steel Works”. The lubricants influence on the main hot rolling technology parameters is analyzed. As a result of the research, there was constructed a regression model to define the “lubricants presence” coefficients in the roll contact. Using lubricants while rolling process makes it possible to reduce external friction forces on the contact surface. From rolling production theory and practice, there is widely known that all kinematic and energy power parameters in one way or another depend on external friction force. While decreasing pressure on the rolls, energy expenses also get reduced. Using lubricants also allows to produce high strength steel brands, capable of withstanding high unit loads, and harsh work conditions. There were used statistics methods to evaluate lubricants impact on rolling parameters changes with the goal of subsequent withdrawal regression function for the stands № 10–13. Regression equations were obtained with the use of “Statistica” software, they allow to define the moments of the main driver’s shaft while using lubricants. There were calculated numerical meanings of the lubricants impact coefficients on the energy power parameters changes depending on the rolled out metal group.
