摘要

通过分析湿型砂低强度、喷涂涂料易起皮、开裂的原因,开发了一种适用于湿型铸钢件用醇基刚玉复合喷涂涂料。这种涂料在50波美度的低密度下有着良好的悬浮稳定性;厚喷涂在湿砂型上,涂层不起皮;与钢液接触时,涂层有着很高的热稳定性,不与FeO等金属氧化物起熔蚀反应而生成低熔渣相,抗钢液渗透能力强。用这种涂料生产的摇枕、侧架铸钢件表面光洁。
        By analysis on mechanisms of low strength of green sand mold and peeling and crack of coating that is sprayed on the green mold, an alcohol base corundum compound spray coating is developed to apply to the green sand mold for steel castings. This coating has excellent suspension stability under low density of 50 Baume degree. The coating is not peeled off or does not appear crack when it is sprayed thickly on the green sand mold.The coat has high heat stability and does not react with metallic oxides such as FeO to produce low melt phase when it touches molten steel. This coating has strong ability to resist penetration of molten steel. Bolster and side frame steel castings with clean surfaces can be produced by this coating.
