LUBRICATING COMPOSITION FOR HOT-ROLLING STEEL |
摘要 |
LUBRICATING COMPOSITION FOR HOT-ROLLING STEEL Disclosed is a lubricating composition for hotrolling steel, which comprises a base oil or base grease and a heat-insulating agent. Especially, (A) an inorganic compound which is melted by an absorption of heat at a temperature lower than 1200.degree.C and (B) an inorganic powder which is not melted or decomposed at a temperature lower than 1200.degree.C and has a heat conductivity lower than 0.01 cal/cm.s..degree.C at room temperature and a friction coefficient smaller than 0.7 are incorporated in specific amounts singly or in combination in the composition. This lubricating composition has an excellent heat-insulating effect and effectively prevents the thermal crown of a work roll.
