用于搪瓷的材料,有作胎体的金属材料(钢板、铸铁)和能够形成玻璃的无机原料。搪瓷设备用的钢材不仅要有好的可搪性、可焊性,而且要有高的塑性。从十九世纪末期开始,低碳钢已被广泛的用来制作搪瓷坯件。搪烧时,由于硅酸盐融体与铁鳞和金属本体发生化学反应而放出 CO、CO_2、H_2、H_2O Materials for enamel, metal materials for carcass (steel, cast iron), and inorganic materials capable of forming glass. The steel used in enamel equipment not only has good enamelability, weldability, but also high plasticity. Since the late nineteenth century, mild steel has been used extensively to make enamel blanks. At the time of enamelling, CO, CO_2, H_2 and H_2O are released due to the chemical reactions between silicate melt and the scale and the metal body
