Development of New Urea Grease for Steel Continuous Casting Machine Under Boundary Lubrication

摘要

The iron and steel industry requires very large and expensive equipment and optimisation of productivity is important. To achieve this, it is necessary to improve the reliability of equipment and to increase operating time by extending the periodical maintenance cycle. The latter is a particularly important task as it is directly linked to the reduction of maintenance costs. Therefore, improvement of reliability and the lifetime prolongation of individual machine elements in the equipment have been advanced by various technology developments at the JFE Steel Corporation (1,2).
