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(yong)途:電熔鎂砂主要(yao)是用(yong)于堿性磚(zhuan)、含碳制(zhi)品和不(bu)定(ding)型耐火材料的良好原料。
2、低硅高(gao)鈣(gai)(gai)電熔(rong)(rong)鎂(mei)砂產品主(zhu)(zhu)要是選(xuan)用(yong)(yong)低硅菱鎂(mei)石為(wei)原料(liao),經高(gao)溫(wen)電熔(rong)(rong)爐(lu)熔(rong)(rong)煉(lian)而成的(de)。其特(te)點是鈣(gai)(gai)硅比大于(yu)(yu) 2 ,晶粒(li)發育充分(fen),顆料(liao)體積密度大于(yu)(yu) 3.50g/cm3以(yi)上。低硅高(gao)鈣(gai)(gai)點熔(rong)(rong)鎂(mei)砂主(zhu)(zhu)要用(yong)(yong)于(yu)(yu)中(zhong)頻感應電爐(lu)熔(rong)(rong)煉(lian)、高(gao)錳鋼(gang)、不(bu)銹鋼(gang)、高(gao)鑼鋼(gang)、堿性磚(zhuan)、含碳制(zhi)品和(he)不(bu)定型耐火材料(liao)的(de)良(liang)好原料(liao)。
3、大(da)結晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)砂生產工(gong)藝:大(da)結晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)砂主要是選(xuan)(xuan)用精選(xuan)(xuan)的(de)(de)特級天(tian)(tian)然菱(ling)鎂(mei)(mei)石(shi)或(huo)優質(zhi)高(gao)(gao)(gao)純(chun)輕(qing)燒鎂(mei)(mei)顆粒(li),在電(dian)(dian)弧爐中(zhong)熔(rong)(rong)融制(zhi)(zhi)得。該(gai)產品具(ju)(ju)(ju)有(you)純(chun)度(du)高(gao)(gao)(gao),結晶(jing)(jing)(jing)粒(li)大(da),結構致密,抗(kang)(kang)渣性(xing)(xing)(xing)強,熱震穩定性(xing)(xing)(xing)好,是一種優良的(de)(de)高(gao)(gao)(gao)溫(wen)電(dian)(dian)氣絕緣(yuan)材料,也是制(zhi)(zhi)作(zuo)鎂(mei)(mei)磚(zhuan),鎂(mei)(mei)碳磚(zhuan)及不定型耐火材料的(de)(de)重(zhong)要原料。廣泛應用于(yu)冶(ye)金、化工(gong)、國防、科研、航(hang)天(tian)(tian)航(hang)空(kong)、家用電(dian)(dian)器元件等。 大(da)結晶(jing)(jing)(jing)電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)砂產品特性(xing)(xing)(xing):純(chun)度(du)高(gao)(gao)(gao)、結晶(jing)(jing)(jing)粒(li)大(da)熔(rong)(rong)、點高(gao)(gao)(gao)結、構致密;熱震穩定性(xing)(xing)(xing)好;具(ju)(ju)(ju)有(you)良好的(de)(de)高(gao)(gao)(gao)溫(wen)抗(kang)(kang)折強度(du);具(ju)(ju)(ju)有(you)良好的(de)(de)抗(kang)(kang)渣性(xing)(xing)(xing)能(neng)(neng)和(he)抗(kang)(kang)腐(fu)蝕(shi)性(xing)(xing)(xing)能(neng)(neng);導熱性(xing)(xing)(xing)能(neng)(neng)強、高(gao)(gao)(gao)度(du)絕緣(yuan)。
