1、普通電熔鎂(mei)(mei)(mei)砂(sha)產品(pin)主(zhu)要(yao)是選用47%以上含量菱鎂(mei)(mei)(mei)石(shi)或輕燒(shao)鎂(mei)(mei)(mei)砂(sha)為(wei)主(zhu)要(yao)原料在電弧中高溫熔融(rong)而成。方鎂(mei)(mei)(mei)石(shi)晶粒大,結構致密(mi),抗渣性強(qiang),高溫體積穩定(ding)(ding)性優(you)越。電熔鎂(mei)(mei)(mei)砂(sha)的主(zhu)要(yao)用途:電熔鎂(mei)(mei)(mei)砂(sha)主(zhu)要(yao)是用于堿(jian)性磚(zhuan)、含碳制(zhi)品(pin)和不定(ding)(ding)型耐火材料的良好原料。
2、低硅高(gao)(gao)鈣電(dian)(dian)(dian)熔(rong)(rong)(rong)鎂砂(sha)產品主(zhu)要(yao)是選用(yong)低硅菱鎂石為原料(liao),經高(gao)(gao)溫電(dian)(dian)(dian)熔(rong)(rong)(rong)爐(lu)熔(rong)(rong)(rong)煉而成的。其特點是鈣硅比大于(yu) 2 ,晶粒發育充(chong)分,顆料(liao)體積密度(du)大于(yu) 3.50g/cm3以上。低硅高(gao)(gao)鈣點熔(rong)(rong)(rong)鎂砂(sha)主(zhu)要(yao)用(yong)于(yu)中頻(pin)感應(ying)電(dian)(dian)(dian)爐(lu)熔(rong)(rong)(rong)煉、高(gao)(gao)錳(meng)鋼(gang)、不(bu)銹鋼(gang)、高(gao)(gao)鑼鋼(gang)、堿性(xing)磚、含碳制品和不(bu)定型耐火材料(liao)的良好原料(liao)。
3、大(da)(da)(da)結晶電(dian)熔(rong)鎂砂生產(chan)工(gong)藝:大(da)(da)(da)結晶電(dian)熔(rong)鎂砂主要是(shi)選用(yong)精選的特級天(tian)然(ran)菱(ling)鎂石或優質高純(chun)(chun)輕燒(shao)鎂顆粒(li),在電(dian)弧爐(lu)中熔(rong)融制得。該產(chan)品(pin)具有純(chun)(chun)度(du)高,結晶粒(li)大(da)(da)(da),結構致密,抗渣性強,熱震穩(wen)定性好,是(shi)一種優良的高溫電(dian)氣絕緣材(cai)料(liao),也是(shi)制作鎂磚(zhuan)(zhuan),鎂碳磚(zhuan)(zhuan)及不定型耐火材(cai)料(liao)的重要原(yuan)料(liao)。廣泛應用(yong)于(yu)冶(ye)金、化(hua)工(gong)、國防(fang)、科(ke)研(yan)、航天(tian)航空、家用(yong)電(dian)器元(yuan)件等。
大結晶電熔鎂砂產品特性(xing):純(chun)度高(gao)、結晶粒大熔、點高(gao)結、構(gou)致密;熱震穩(wen)定性(xing)好;具有良(liang)好的高(gao)溫抗折強度;具有良(liang)好的抗渣性(xing)能(neng)和抗腐(fu)蝕(shi)性(xing)能(neng);導(dao)熱性(xing)能(neng)強、高(gao)度絕緣。
