欽州電熔鎂砂主要有三大(da)(da)種類；一、普通電(dian)(dian)(dian)熔(rong)(rong)鎂砂，二、低硅高鈣(gai)電(dian)(dian)(dian)熔(rong)(rong)鎂砂，三、大(da)(da)結晶(jing)電(dian)(dian)(dian)熔(rong)(rong)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。電熔鎂砂的主要用途(tu)：電熔鎂砂(sha)主要是用于(yu)堿性磚、含碳制品(pin)和不定型耐火材料的良好原料。

 2、低硅(gui)(gui)高(gao)鈣電(dian)(dian)熔(rong)鎂(mei)砂產(chan)品主要(yao)是(shi)選用低硅(gui)(gui)菱鎂(mei)石(shi)為原(yuan)料(liao)，經高(gao)溫電(dian)(dian)熔(rong)爐(lu)熔(rong)煉而成(cheng)的。其特點(dian)是(shi)鈣硅(gui)(gui)比大于(yu) 2 ，晶粒發育(yu)充(chong)分(fen)，顆料(liao)體積密度大于(yu) 3.50g/cm3以(yi)上(shang)。低硅(gui)(gui)高(gao)鈣點(dian)熔(rong)鎂(mei)砂主要(yao)用于(yu)中頻感應電(dian)(dian)爐(lu)熔(rong)煉、高(gao)錳鋼(gang)、不銹鋼(gang)、高(gao)鑼鋼(gang)、堿(jian)性磚、含(han)碳制品和不定(ding)型耐(nai)火(huo)材料(liao)的良好(hao)原(yuan)料(liao)。

3、大結晶(jing)電(dian)(dian)熔(rong)鎂(mei)砂(sha)生產(chan)(chan)工(gong)藝：大結晶(jing)電(dian)(dian)熔(rong)鎂(mei)砂(sha)主(zhu)要(yao)是(shi)選用(yong)(yong)精選的特(te)級天(tian)然菱鎂(mei)石或優質高(gao)純(chun)輕燒鎂(mei)顆(ke)粒，在電(dian)(dian)弧爐中熔(rong)融制得。該(gai)產(chan)(chan)品(pin)具有純(chun)度高(gao)，結晶(jing)粒大，結構致密(mi)，抗(kang)渣性(xing)強，熱(re)震穩定(ding)(ding)性(xing)好(hao)，是(shi)一(yi)種(zhong)優良(liang)(liang)的高(gao)溫(wen)(wen)電(dian)(dian)氣絕(jue)緣材料，也是(shi)制作鎂(mei)磚，鎂(mei)碳(tan)磚及不定(ding)(ding)型耐火材料的重要(yao)原料。廣泛(fan)應用(yong)(yong)于(yu)冶金、化(hua)工(gong)、國(guo)防(fang)、科(ke)研、航天(tian)航空、家(jia)用(yong)(yong)電(dian)(dian)器元件等。 大結晶(jing)電(dian)(dian)熔(rong)鎂(mei)砂(sha)產(chan)(chan)品(pin)特(te)性(xing)：純(chun)度高(gao)、結晶(jing)粒大熔(rong)、點高(gao)結、構致密(mi)；熱(re)震穩定(ding)(ding)性(xing)好(hao)；具有良(liang)(liang)好(hao)的高(gao)溫(wen)(wen)抗(kang)折強度；具有良(liang)(liang)好(hao)的抗(kang)渣性(xing)能(neng)和(he)抗(kang)腐蝕(shi)性(xing)能(neng)；導熱(re)性(xing)能(neng)強、高(gao)度絕(jue)緣。
