博爾塔拉電熔鎂砂主(zhu)要有三大種類；一、普通電熔鎂(mei)砂(sha)，二、低硅(gui)高鈣電熔鎂(mei)砂(sha)，三、大結晶(jing)電熔鎂(mei)砂(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。電熔鎂砂的主要(yao)用途：電熔(rong)鎂砂主要(yao)是用于堿性磚、含碳制品和不定型耐火(huo)材料的良(liang)好(hao)原料。

 2、低(di)(di)硅高(gao)鈣電(dian)熔(rong)(rong)(rong)鎂(mei)砂產品主(zhu)要是(shi)選用(yong)低(di)(di)硅菱(ling)鎂(mei)石為原(yuan)料(liao)，經高(gao)溫電(dian)熔(rong)(rong)(rong)爐(lu)熔(rong)(rong)(rong)煉而成的。其特點是(shi)鈣硅比大(da)于 2 ，晶粒發(fa)育充分，顆料(liao)體(ti)積(ji)密度大(da)于 3.50g/cm3以上。低(di)(di)硅高(gao)鈣點熔(rong)(rong)(rong)鎂(mei)砂主(zhu)要用(yong)于中(zhong)頻(pin)感應電(dian)爐(lu)熔(rong)(rong)(rong)煉、高(gao)錳(meng)鋼(gang)、不銹鋼(gang)、高(gao)鑼鋼(gang)、堿性磚、含碳(tan)制(zhi)品和不定型耐(nai)火材(cai)料(liao)的良好(hao)原(yuan)料(liao)。

3、大(da)結(jie)晶(jing)電(dian)(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂生(sheng)產(chan)(chan)工藝：大(da)結(jie)晶(jing)電(dian)(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂主(zhu)要(yao)是(shi)(shi)選用(yong)精選的特級天然(ran)菱鎂(mei)石或優質高(gao)(gao)純輕燒鎂(mei)顆粒，在電(dian)(dian)(dian)(dian)弧爐中熔(rong)(rong)融制得。該(gai)產(chan)(chan)品(pin)具有(you)純度(du)高(gao)(gao)，結(jie)晶(jing)粒大(da)，結(jie)構(gou)致密，抗(kang)渣性(xing)(xing)強，熱震(zhen)穩定性(xing)(xing)好，是(shi)(shi)一(yi)種優良(liang)的高(gao)(gao)溫電(dian)(dian)(dian)(dian)氣(qi)絕緣(yuan)材(cai)料，也(ye)是(shi)(shi)制作鎂(mei)磚(zhuan)，鎂(mei)碳磚(zhuan)及不定型(xing)耐火材(cai)料的重要(yao)原(yuan)料。廣(guang)泛(fan)應用(yong)于冶金、化工、國防(fang)、科研、航(hang)天航(hang)空、家用(yong)電(dian)(dian)(dian)(dian)器元件(jian)等。 大(da)結(jie)晶(jing)電(dian)(dian)(dian)(dian)熔(rong)(rong)鎂(mei)砂產(chan)(chan)品(pin)特性(xing)(xing)：純度(du)高(gao)(gao)、結(jie)晶(jing)粒大(da)熔(rong)(rong)、點高(gao)(gao)結(jie)、構(gou)致密；熱震(zhen)穩定性(xing)(xing)好；具有(you)良(liang)好的高(gao)(gao)溫抗(kang)折(zhe)強度(du)；具有(you)良(liang)好的抗(kang)渣性(xing)(xing)能(neng)和抗(kang)腐蝕性(xing)(xing)能(neng)；導熱性(xing)(xing)能(neng)強、高(gao)(gao)度(du)絕緣(yuan)。
