1、普通(tong)電熔(rong)鎂(mei)砂(sha)(sha)產品主(zhu)要是選用(yong)47%以上含量菱鎂(mei)石或輕燒鎂(mei)砂(sha)(sha)為主(zhu)要原(yuan)料在電弧中高溫(wen)(wen)熔(rong)融而成(cheng)。方鎂(mei)石晶粒大,結構致密,抗渣性(xing)強,高溫(wen)(wen)體積穩定性(xing)優越。電熔(rong)鎂(mei)砂(sha)(sha)的主(zhu)要用(yong)途(tu):電熔(rong)鎂(mei)砂(sha)(sha)主(zhu)要是用(yong)于(yu)堿性(xing)磚、含碳制品和不定型耐火材(cai)料的良好原(yuan)料。
2、低(di)(di)硅高(gao)鈣電熔(rong)鎂(mei)(mei)砂(sha)產品(pin)主(zhu)要(yao)(yao)是選用低(di)(di)硅菱鎂(mei)(mei)石為原料,經高(gao)溫電熔(rong)爐熔(rong)煉而成的(de)。其特點(dian)是鈣硅比(bi)大于(yu) 2 ,晶粒發育充分(fen),顆(ke)料體積密度大于(yu) 3.50g/cm3以上。低(di)(di)硅高(gao)鈣點(dian)熔(rong)鎂(mei)(mei)砂(sha)主(zhu)要(yao)(yao)用于(yu)中頻感應電爐熔(rong)煉、高(gao)錳鋼、不銹鋼、高(gao)鑼鋼、堿性磚、含碳(tan)制品(pin)和不定(ding)型耐(nai)火材(cai)料的(de)良好原料。
3、大(da)(da)結(jie)晶電(dian)熔鎂砂(sha)生產工(gong)(gong)藝:大(da)(da)結(jie)晶電(dian)熔鎂砂(sha)主要(yao)是(shi)(shi)選(xuan)用精選(xuan)的特級天(tian)然菱鎂石或優質(zhi)高(gao)純輕燒鎂顆(ke)粒,在電(dian)弧爐中熔融制(zhi)得。該產品(pin)具有純度高(gao),結(jie)晶粒大(da)(da),結(jie)構致密,抗渣性(xing)強,熱震穩定(ding)性(xing)好,是(shi)(shi)一種優良的高(gao)溫電(dian)氣(qi)絕緣(yuan)材料(liao),也(ye)是(shi)(shi)制(zhi)作(zuo)鎂磚,鎂碳磚及不定(ding)型耐火材料(liao)的重(zhong)要(yao)原(yuan)料(liao)。廣泛應用于冶金、化(hua)工(gong)(gong)、國防、科研、航天(tian)航空、家用電(dian)器元件(jian)等(deng)。
大(da)結(jie)晶電(dian)熔(rong)鎂砂(sha)產品特性(xing):純度高、結(jie)晶粒大(da)熔(rong)、點(dian)高結(jie)、構致密;熱(re)震(zhen)穩定性(xing)好;具(ju)(ju)有良好的高溫抗(kang)(kang)(kang)折強度;具(ju)(ju)有良好的抗(kang)(kang)(kang)渣性(xing)能(neng)和抗(kang)(kang)(kang)腐(fu)蝕性(xing)能(neng);導熱(re)性(xing)能(neng)強、高度絕緣。
