電熔(rong)(rong)(rong)磚的制造工藝是將鋯英(ying)石(shi)(shi)砂(sha)和工業(ye)氧化鋁粉按(an)1:1配(pei)合,外加(jia)少量NaZO(以(yi)碳酸鈉的形式(shi)加(jia)入)、B2O(以(yi)硼酸或硼砂(sha)的形式(shi)加(jia)入)熔(rong)(rong)(rong)劑,混合均勻,經1900~2000℃熔(rong)(rong)(rong)化后澆鑄(zhu)(zhu)成型,可制得含 zrO233%的熔(rong)(rong)(rong)鑄(zhu)(zhu)磚。在此基礎上,采用(yong)部分脫硅鋯英(ying)石(shi)(shi)砂(sha)作原(yuan)料,可制得含ZrO2 36%~41%的熔(rong)(rong)(rong)鑄(zhu)(zhu)磚
