<p>PURPOSE:To provide the glass lubricant for hot extrusion capable of greatly reducing the dimensional fluctuation between the top and the bottom of an extruded product in the hot extrusion. CONSTITUTION:The glass lubricant for hot extrusion has the composition consisting of, by weight, 10-25% CaO, 3-10% Al2O3, 10-30% K2O, and the balance SiO2 with inevitable impurities. The yield of the stainless steel and the super alloy can be greatly improved thereby, and the extent of the shape of the shapes to meet the requests of users can be widened.</p> |
