Influence of Concentration of Sodium Metasilicate and Descaling on the High Temperature Lubricating Effects Evaluated by Hot Rolling Mill

Lubricant is vital to improve energy efficiency and workpiece durability for the moving counterpart. High-temperature lubricants are important hot rolling process reduce force protect roller strips. The current paper concerns eco-friendly sodium metasilicate as a high-temperature lubricant. A mill employed evaluate lubrication effect of metasilicate. influence crucial factors concentration lubricant descaling discussed; rolled surface was analyzed by scanning electron microscopy, dispersive spectroscopy, 3D profilometer. results depict that can about 7.8% when 18% above, stripe makes more effective, which reach 12.7% reduction in force. This attributed formed melts silicate layer offers an easy shearing interface. For un-descaled samples, will be compacted mixed with oxide scale, weakens effect. work suggests rolling; vital, not only quality product but also useful selection glass
