【Abstract】 The influence of fire-resisting material grain distribution on the performance of surface coating, the consistency between fire-resisting material and silicasol as well as the influences of forming process on the surface coating and metal penetration were studied. Such studies have an important reference and application value in properly controlling the silicasol paints and the performance of its surface coating and improving the surface quality of finished-casting.更多还原
