津南電熔鎂砂主要(yao)有(you)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(de)主要用途：電(dian)熔(rong)鎂砂主要是用于堿(jian)性磚、含碳制品和(he)不定型(xing)耐火材(cai)料的(de)良(liang)好原料。

 2、低硅高(gao)(gao)(gao)鈣電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)砂(sha)產品主(zhu)要是(shi)選(xuan)用低硅菱(ling)鎂(mei)(mei)石為原料(liao)，經高(gao)(gao)(gao)溫電(dian)(dian)熔(rong)(rong)爐(lu)熔(rong)(rong)煉(lian)(lian)而成的。其特點是(shi)鈣硅比大于 2 ，晶粒發育充分，顆(ke)料(liao)體(ti)積密度(du)大于 3.50g/cm3以上。低硅高(gao)(gao)(gao)鈣點熔(rong)(rong)鎂(mei)(mei)砂(sha)主(zhu)要用于中頻感應電(dian)(dian)爐(lu)熔(rong)(rong)煉(lian)(lian)、高(gao)(gao)(gao)錳(meng)鋼、不(bu)銹鋼、高(gao)(gao)(gao)鑼鋼、堿性(xing)磚、含碳(tan)制品和不(bu)定型(xing)耐火材料(liao)的良好原料(liao)。

3、大(da)結(jie)(jie)晶(jing)電(dian)熔(rong)(rong)(rong)(rong)鎂(mei)(mei)砂生產工(gong)藝：大(da)結(jie)(jie)晶(jing)電(dian)熔(rong)(rong)(rong)(rong)鎂(mei)(mei)砂主要是(shi)選用(yong)精選的特級天然菱鎂(mei)(mei)石或優質(zhi)高(gao)純(chun)(chun)輕燒鎂(mei)(mei)顆粒，在電(dian)弧(hu)爐中(zhong)熔(rong)(rong)(rong)(rong)融制(zhi)得。該(gai)產品具有純(chun)(chun)度高(gao)，結(jie)(jie)晶(jing)粒大(da)，結(jie)(jie)構(gou)致密(mi)，抗(kang)(kang)渣(zha)性(xing)(xing)強，熱(re)震穩定(ding)(ding)性(xing)(xing)好(hao)，是(shi)一種優良的高(gao)溫(wen)電(dian)氣絕(jue)緣材(cai)料(liao)，也是(shi)制(zhi)作鎂(mei)(mei)磚，鎂(mei)(mei)碳磚及(ji)不定(ding)(ding)型(xing)耐(nai)火材(cai)料(liao)的重要原料(liao)。廣泛(fan)應(ying)用(yong)于(yu)冶(ye)金(jin)、化(hua)工(gong)、國防、科研(yan)、航(hang)天航(hang)空、家用(yong)電(dian)器元件等。 大(da)結(jie)(jie)晶(jing)電(dian)熔(rong)(rong)(rong)(rong)鎂(mei)(mei)砂產品特性(xing)(xing)：純(chun)(chun)度高(gao)、結(jie)(jie)晶(jing)粒大(da)熔(rong)(rong)(rong)(rong)、點(dian)高(gao)結(jie)(jie)、構(gou)致密(mi)；熱(re)震穩定(ding)(ding)性(xing)(xing)好(hao)；具有良好(hao)的高(gao)溫(wen)抗(kang)(kang)折強度；具有良好(hao)的抗(kang)(kang)渣(zha)性(xing)(xing)能(neng)(neng)和抗(kang)(kang)腐蝕性(xing)(xing)能(neng)(neng)；導熱(re)性(xing)(xing)能(neng)(neng)強、高(gao)度絕(jue)緣。
