1、普通電(dian)(dian)(dian)熔(rong)鎂(mei)砂產品主要(yao)是選用(yong)47%以(yi)上含(han)量菱鎂(mei)石(shi)(shi)或輕燒鎂(mei)砂為(wei)主要(yao)原料在(zai)電(dian)(dian)(dian)弧(hu)中高溫(wen)熔(rong)融(rong)而成。方鎂(mei)石(shi)(shi)晶粒大(da)，結構(gou)致(zhi)密，抗渣(zha)性強，高溫(wen)體積(ji)穩定(ding)(ding)性優越。電(dian)(dian)(dian)熔(rong)鎂(mei)砂的主要(yao)用(yong)途：電(dian)(dian)(dian)熔(rong)鎂(mei)砂主要(yao)是用(yong)于堿性磚、含(han)碳(tan)制品和不(bu)定(ding)(ding)型耐火材料的良(liang)好原料。

2、低(di)(di)硅高(gao)鈣電熔(rong)(rong)(rong)鎂砂(sha)產品主(zhu)要(yao)是選用低(di)(di)硅菱鎂石為原料，經(jing)高(gao)溫電熔(rong)(rong)(rong)爐熔(rong)(rong)(rong)煉而成(cheng)的。其特點(dian)是鈣硅比大(da)于(yu) 2 ，晶(jing)粒發育充分，顆料體(ti)積密(mi)度大(da)于(yu) 3.50g/cm3以上。低(di)(di)硅高(gao)鈣點(dian)熔(rong)(rong)(rong)鎂砂(sha)主(zhu)要(yao)用于(yu)中頻感應電爐熔(rong)(rong)(rong)煉、高(gao)錳鋼(gang)、不銹(xiu)鋼(gang)、高(gao)鑼鋼(gang)、堿(jian)性磚(zhuan)、含碳制品和不定型耐火(huo)材料的良好原料。

3、大(da)結晶電(dian)(dian)熔鎂(mei)砂(sha)生產(chan)工藝：大(da)結晶電(dian)(dian)熔鎂(mei)砂(sha)主(zhu)要(yao)是選(xuan)用精選(xuan)的(de)特級天然(ran)菱鎂(mei)石或優質高(gao)純(chun)輕燒鎂(mei)顆粒(li)，在電(dian)(dian)弧爐中熔融制得。該產(chan)品具有純(chun)度高(gao)，結晶粒(li)大(da)，結構(gou)致(zhi)密(mi)，抗渣性強，熱震穩定(ding)性好，是一種優良的(de)高(gao)溫電(dian)(dian)氣絕緣材料，也(ye)是制作鎂(mei)磚，鎂(mei)碳(tan)磚及不(bu)定(ding)型耐火材料的(de)重要(yao)原(yuan)料。廣(guang)泛應用于冶金、化工、國防、科(ke)研、航(hang)天航(hang)空、家(jia)用電(dian)(dian)器元件等。

大結晶電熔鎂(mei)砂(sha)產品特性(xing)：純(chun)度(du)(du)高、結晶粒大熔、點高結、構致(zhi)密；熱(re)震穩定(ding)性(xing)好(hao)；具有(you)良好(hao)的(de)高溫抗折強度(du)(du)；具有(you)良好(hao)的(de)抗渣性(xing)能和抗腐蝕性(xing)能；導熱(re)性(xing)能強、高度(du)(du)絕(jue)緣。
