2、低(di)硅(gui)高(gao)鈣電(dian)熔(rong)(rong)鎂砂(sha)(sha)產(chan)品主(zhu)要是(shi)選用低(di)硅(gui)菱鎂石為原料，經高(gao)溫電(dian)熔(rong)(rong)爐熔(rong)(rong)煉而成的(de)。其特(te)點(dian)是(shi)鈣硅(gui)比(bi)大(da)于 2 ，晶(jing)粒發育(yu)充分(fen)，顆料體(ti)積(ji)密度大(da)于 3.50g/cm3以上(shang)。低(di)硅(gui)高(gao)鈣點(dian)熔(rong)(rong)鎂砂(sha)(sha)主(zhu)要用于中頻感應電(dian)爐熔(rong)(rong)煉、高(gao)錳(meng)鋼(gang)、不銹鋼(gang)、高(gao)鑼鋼(gang)、堿性磚、含碳制品和不定型耐火(huo)材料的(de)良好原料。

3、大結(jie)晶電(dian)(dian)熔(rong)鎂(mei)砂(sha)生產(chan)工(gong)藝：大結(jie)晶電(dian)(dian)熔(rong)鎂(mei)砂(sha)主要(yao)(yao)是選(xuan)用(yong)精選(xuan)的(de)特級天然菱(ling)鎂(mei)石或優質高純輕燒鎂(mei)顆(ke)粒，在電(dian)(dian)弧爐中熔(rong)融制得。該產(chan)品具(ju)有純度高，結(jie)晶粒大，結(jie)構致密(mi)，抗渣性強，熱(re)震(zhen)穩定性好，是一種優良(liang)的(de)高溫電(dian)(dian)氣絕緣材料，也是制作鎂(mei)磚，鎂(mei)碳磚及不(bu)定型耐(nai)火材料的(de)重要(yao)(yao)原料。廣泛應用(yong)于冶金、化工(gong)、國防、科研、航天航空、家(jia)用(yong)電(dian)(dian)器元(yuan)件等。

大結晶(jing)(jing)電熔(rong)鎂(mei)砂產品(pin)特(te)性(xing)：純(chun)度高(gao)、結晶(jing)(jing)粒(li)大熔(rong)、點高(gao)結、構致密；熱震穩定性(xing)好；具有良(liang)好的高(gao)溫抗(kang)(kang)折強度；具有良(liang)好的抗(kang)(kang)渣性(xing)能(neng)和抗(kang)(kang)腐蝕(shi)性(xing)能(neng)；導熱性(xing)能(neng)強、高(gao)度絕緣。
