涪陵電熔鎂砂主(zhu)要(yao)有三大(da)種類；一、普通(tong)電(dian)熔(rong)鎂砂(sha)，二、低硅高鈣(gai)電(dian)熔(rong)鎂砂(sha)，三、大(da)結(jie)晶(jing)電(dian)熔(rong)鎂砂(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。電熔鎂砂的主要用途：電熔鎂砂主要是用于(yu)堿性(xing)磚(zhuan)、含碳制品和(he)不定(ding)型耐火材(cai)料的良(liang)好原料。

 2、低(di)(di)硅(gui)(gui)(gui)高鈣電(dian)熔(rong)(rong)(rong)鎂(mei)砂產品主要(yao)是選用低(di)(di)硅(gui)(gui)(gui)菱鎂(mei)石為原料，經高溫電(dian)熔(rong)(rong)(rong)爐(lu)熔(rong)(rong)(rong)煉而(er)成的。其(qi)特點是鈣硅(gui)(gui)(gui)比大于(yu) 2 ，晶(jing)粒發育充分，顆料體積密度大于(yu) 3.50g/cm3以上。低(di)(di)硅(gui)(gui)(gui)高鈣點熔(rong)(rong)(rong)鎂(mei)砂主要(yao)用于(yu)中頻感應(ying)電(dian)爐(lu)熔(rong)(rong)(rong)煉、高錳(meng)鋼(gang)、不銹鋼(gang)、高鑼鋼(gang)、堿性磚(zhuan)、含(han)碳制品和不定(ding)型(xing)耐火材(cai)料的良好原料。

3、大結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)生產工(gong)藝：大結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)主要(yao)是(shi)選用(yong)精(jing)選的(de)(de)特(te)級天(tian)然菱鎂(mei)石或優質高純(chun)(chun)輕(qing)燒鎂(mei)顆(ke)粒，在電(dian)(dian)(dian)弧爐中熔(rong)(rong)(rong)融制(zhi)得。該產品(pin)(pin)具(ju)有(you)(you)純(chun)(chun)度高，結晶(jing)(jing)粒大，結構(gou)(gou)致密(mi)，抗渣性(xing)強(qiang)，熱(re)震穩(wen)定性(xing)好，是(shi)一(yi)種優良的(de)(de)高溫(wen)電(dian)(dian)(dian)氣絕(jue)緣(yuan)材料，也是(shi)制(zhi)作鎂(mei)磚(zhuan)，鎂(mei)碳磚(zhuan)及(ji)不定型耐火材料的(de)(de)重要(yao)原料。廣泛應用(yong)于(yu)冶金(jin)、化工(gong)、國防、科研、航(hang)天(tian)航(hang)空、家(jia)用(yong)電(dian)(dian)(dian)器元件等。 大結晶(jing)(jing)電(dian)(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)(sha)產品(pin)(pin)特(te)性(xing)：純(chun)(chun)度高、結晶(jing)(jing)粒大熔(rong)(rong)(rong)、點高結、構(gou)(gou)致密(mi)；熱(re)震穩(wen)定性(xing)好；具(ju)有(you)(you)良好的(de)(de)高溫(wen)抗折強(qiang)度；具(ju)有(you)(you)良好的(de)(de)抗渣性(xing)能和抗腐蝕性(xing)能；導熱(re)性(xing)能強(qiang)、高度絕(jue)緣(yuan)。
