四川電熔鎂砂主要有三大種(zhong)類；一、普通(tong)電熔鎂砂，二、低硅高(gao)鈣(gai)電熔鎂砂，三、大結晶電熔鎂砂；  

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(de)主(zhu)要(yao)用(yong)途：電(dian)熔鎂砂主(zhu)要(yao)是用(yong)于(yu)堿性磚(zhuan)、含碳制品和不定型耐火材料(liao)的(de)良好原料(liao)。

 2、低硅(gui)高鈣電(dian)(dian)熔(rong)(rong)(rong)(rong)鎂砂產品主要是選(xuan)用(yong)低硅(gui)菱鎂石為原(yuan)料，經高溫電(dian)(dian)熔(rong)(rong)(rong)(rong)爐熔(rong)(rong)(rong)(rong)煉而成的(de)。其特點是鈣硅(gui)比大于(yu) 2 ，晶粒發育充分，顆料體(ti)積(ji)密(mi)度大于(yu) 3.50g/cm3以上。低硅(gui)高鈣點熔(rong)(rong)(rong)(rong)鎂砂主要用(yong)于(yu)中頻(pin)感(gan)應電(dian)(dian)爐熔(rong)(rong)(rong)(rong)煉、高錳(meng)鋼、不銹鋼、高鑼鋼、堿性磚、含碳制品和不定型(xing)耐(nai)火(huo)材料的(de)良(liang)好原(yuan)料。

3、大結(jie)晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)生產工藝：大結(jie)晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)主(zhu)要(yao)是選(xuan)用精選(xuan)的特級天(tian)然菱鎂(mei)石(shi)或優(you)質高(gao)(gao)純輕燒鎂(mei)顆粒，在電(dian)(dian)弧爐中熔(rong)(rong)(rong)融(rong)制得(de)。該產品具(ju)有純度(du)(du)高(gao)(gao)，結(jie)晶(jing)(jing)(jing)粒大，結(jie)構致密，抗渣性(xing)(xing)強(qiang)(qiang)，熱震穩(wen)定性(xing)(xing)好，是一種優(you)良的高(gao)(gao)溫電(dian)(dian)氣絕緣材料(liao)，也是制作鎂(mei)磚(zhuan)，鎂(mei)碳磚(zhuan)及不(bu)定型耐火材料(liao)的重要(yao)原料(liao)。廣泛應用于冶(ye)金、化(hua)工、國防、科研、航天(tian)航空、家用電(dian)(dian)器元(yuan)件(jian)等。 大結(jie)晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)產品特性(xing)(xing)：純度(du)(du)高(gao)(gao)、結(jie)晶(jing)(jing)(jing)粒大熔(rong)(rong)(rong)、點(dian)高(gao)(gao)結(jie)、構致密；熱震穩(wen)定性(xing)(xing)好；具(ju)有良好的高(gao)(gao)溫抗折(zhe)強(qiang)(qiang)度(du)(du)；具(ju)有良好的抗渣性(xing)(xing)能(neng)(neng)和抗腐蝕性(xing)(xing)能(neng)(neng)；導(dao)熱性(xing)(xing)能(neng)(neng)強(qiang)(qiang)、高(gao)(gao)度(du)(du)絕緣。
