內蒙古電熔鎂砂主要有三大(da)種類；一、普通(tong)電熔(rong)鎂(mei)砂，二、低硅高鈣電熔(rong)鎂(mei)砂，三、大(da)結晶電熔(rong)鎂(mei)砂；  

1、普通電熔鎂砂產品主要是選用47%以上含量菱鎂石或輕燒鎂砂為主要原料在電弧中高溫熔融而成。方鎂石晶粒大，結構致密，抗渣性強，高溫體積穩定性優越。電熔鎂砂的主要(yao)用(yong)途：電熔鎂砂主要(yao)是用(yong)于堿性磚、含(han)碳制品(pin)和不定(ding)型耐(nai)火(huo)材料(liao)的良好原料(liao)。

 2、低硅(gui)高(gao)鈣電(dian)(dian)熔(rong)鎂砂產品主(zhu)要(yao)是選(xuan)用低硅(gui)菱鎂石為原料(liao)，經高(gao)溫電(dian)(dian)熔(rong)爐熔(rong)煉(lian)而成的。其特點(dian)是鈣硅(gui)比大于 2 ，晶粒發(fa)育充分，顆料(liao)體積密度大于 3.50g/cm3以上。低硅(gui)高(gao)鈣點(dian)熔(rong)鎂砂主(zhu)要(yao)用于中頻感應(ying)電(dian)(dian)爐熔(rong)煉(lian)、高(gao)錳鋼、不(bu)銹鋼、高(gao)鑼(luo)鋼、堿性磚、含碳制(zhi)品和不(bu)定型(xing)耐(nai)火材料(liao)的良好原料(liao)。

3、大(da)(da)結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂(sha)生產工藝：大(da)(da)結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂(sha)主要是(shi)(shi)選用(yong)精選的特級(ji)天然菱(ling)鎂(mei)石或優(you)質(zhi)高(gao)(gao)純輕燒鎂(mei)顆粒，在電(dian)(dian)(dian)弧爐中(zhong)熔(rong)(rong)融制得(de)。該產品(pin)具(ju)有(you)(you)純度高(gao)(gao)，結晶(jing)(jing)粒大(da)(da)，結構(gou)致(zhi)(zhi)密，抗渣性(xing)(xing)強，熱(re)(re)震穩定性(xing)(xing)好，是(shi)(shi)一(yi)種優(you)良的高(gao)(gao)溫電(dian)(dian)(dian)氣(qi)絕緣材料，也是(shi)(shi)制作鎂(mei)磚(zhuan)，鎂(mei)碳(tan)磚(zhuan)及不定型耐火(huo)材料的重要原料。廣泛(fan)應(ying)用(yong)于冶金、化工、國(guo)防(fang)、科研、航天航空、家用(yong)電(dian)(dian)(dian)器元件(jian)等。 大(da)(da)結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂(sha)產品(pin)特性(xing)(xing)：純度高(gao)(gao)、結晶(jing)(jing)粒大(da)(da)熔(rong)(rong)、點高(gao)(gao)結、構(gou)致(zhi)(zhi)密；熱(re)(re)震穩定性(xing)(xing)好；具(ju)有(you)(you)良好的高(gao)(gao)溫抗折強度；具(ju)有(you)(you)良好的抗渣性(xing)(xing)能和抗腐蝕(shi)性(xing)(xing)能；導熱(re)(re)性(xing)(xing)能強、高(gao)(gao)度絕緣。
