岳陽電熔鎂砂主要(yao)有三(san)大種(zhong)類；一、普通(tong)電熔(rong)鎂(mei)(mei)砂(sha)(sha)(sha)，二、低硅高鈣電熔(rong)鎂(mei)(mei)砂(sha)(sha)(sha)，三(san)、大結晶電熔(rong)鎂(mei)(mei)砂(sha)(sha)(sha)；  

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)主要用途：電(dian)熔鎂砂主要是用于堿性磚(zhuan)、含碳制品和不定型耐火(huo)材料(liao)的(de)良好原料(liao)。

 2、低(di)硅(gui)高(gao)鈣電(dian)(dian)熔(rong)鎂砂產品主(zhu)要(yao)是選用低(di)硅(gui)菱鎂石(shi)為原料，經高(gao)溫電(dian)(dian)熔(rong)爐熔(rong)煉而成的。其特(te)點是鈣硅(gui)比大于 2 ，晶粒發育充(chong)分(fen)，顆料體積密度大于 3.50g/cm3以上。低(di)硅(gui)高(gao)鈣點熔(rong)鎂砂主(zhu)要(yao)用于中(zhong)頻感應電(dian)(dian)爐熔(rong)煉、高(gao)錳鋼、不(bu)銹鋼、高(gao)鑼鋼、堿(jian)性磚、含(han)碳制品和不(bu)定(ding)型耐火材料的良好(hao)原料。

3、大結(jie)晶(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂生產(chan)(chan)工(gong)藝：大結(jie)晶(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂主要(yao)是(shi)選用(yong)精選的(de)特級天(tian)然菱鎂(mei)石或優(you)質高純輕燒鎂(mei)顆粒(li)(li)，在電(dian)(dian)(dian)弧爐中熔(rong)(rong)融(rong)制(zhi)得(de)。該產(chan)(chan)品具(ju)有純度高，結(jie)晶(jing)粒(li)(li)大，結(jie)構(gou)致(zhi)密，抗(kang)渣(zha)(zha)性(xing)(xing)強(qiang)，熱震穩定(ding)性(xing)(xing)好(hao)，是(shi)一種優(you)良的(de)高溫電(dian)(dian)(dian)氣絕緣(yuan)材(cai)料(liao)，也是(shi)制(zhi)作(zuo)鎂(mei)磚，鎂(mei)碳磚及(ji)不定(ding)型(xing)耐火材(cai)料(liao)的(de)重要(yao)原料(liao)。廣泛(fan)應用(yong)于冶(ye)金、化(hua)工(gong)、國防、科研(yan)、航(hang)天(tian)航(hang)空、家用(yong)電(dian)(dian)(dian)器元件(jian)等。 大結(jie)晶(jing)電(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂產(chan)(chan)品特性(xing)(xing)：純度高、結(jie)晶(jing)粒(li)(li)大熔(rong)(rong)、點(dian)高結(jie)、構(gou)致(zhi)密；熱震穩定(ding)性(xing)(xing)好(hao)；具(ju)有良好(hao)的(de)高溫抗(kang)折強(qiang)度；具(ju)有良好(hao)的(de)抗(kang)渣(zha)(zha)性(xing)(xing)能(neng)和抗(kang)腐(fu)蝕(shi)性(xing)(xing)能(neng)；導熱性(xing)(xing)能(neng)強(qiang)、高度絕緣(yuan)。
