1、普通電(dian)(dian)熔(rong)鎂(mei)(mei)(mei)砂(sha)產(chan)品主(zhu)(zhu)要是選用(yong)47%以上含量(liang)菱鎂(mei)(mei)(mei)石或(huo)輕燒鎂(mei)(mei)(mei)砂(sha)為主(zhu)(zhu)要原料在電(dian)(dian)弧中高(gao)溫熔(rong)融而成(cheng)。方鎂(mei)(mei)(mei)石晶粒大,結構致密,抗渣性(xing)強,高(gao)溫體(ti)積(ji)穩定性(xing)優(you)越。電(dian)(dian)熔(rong)鎂(mei)(mei)(mei)砂(sha)的主(zhu)(zhu)要用(yong)途:電(dian)(dian)熔(rong)鎂(mei)(mei)(mei)砂(sha)主(zhu)(zhu)要是用(yong)于(yu)堿性(xing)磚、含碳制品和不定型耐火材料的良(liang)好原料。
2、低(di)硅(gui)(gui)高鈣電熔(rong)(rong)(rong)鎂(mei)(mei)砂(sha)產品主要是選用(yong)低(di)硅(gui)(gui)菱鎂(mei)(mei)石為原料(liao),經高溫電熔(rong)(rong)(rong)爐熔(rong)(rong)(rong)煉(lian)而成的(de)。其特點是鈣硅(gui)(gui)比大于 2 ,晶粒發(fa)育(yu)充分(fen),顆料(liao)體積密度大于 3.50g/cm3以(yi)上(shang)。低(di)硅(gui)(gui)高鈣點熔(rong)(rong)(rong)鎂(mei)(mei)砂(sha)主要用(yong)于中頻感應電爐熔(rong)(rong)(rong)煉(lian)、高錳(meng)鋼、不(bu)(bu)銹鋼、高鑼鋼、堿性(xing)磚、含碳制(zhi)品和不(bu)(bu)定型耐火材料(liao)的(de)良好(hao)原料(liao)。
3、大(da)結晶(jing)電(dian)(dian)熔(rong)鎂砂生產工(gong)藝(yi):大(da)結晶(jing)電(dian)(dian)熔(rong)鎂砂主要(yao)是選用(yong)精(jing)選的特級天然(ran)菱(ling)鎂石或(huo)優質高純(chun)輕(qing)燒鎂顆粒(li),在電(dian)(dian)弧爐中熔(rong)融制(zhi)得。該產品具有純(chun)度(du)高,結晶(jing)粒(li)大(da),結構致密,抗渣性強,熱(re)震穩(wen)定性好,是一種優良的高溫電(dian)(dian)氣絕緣材料,也是制(zhi)作鎂磚(zhuan),鎂碳磚(zhuan)及不定型耐火材料的重要(yao)原料。廣泛應用(yong)于冶(ye)金、化工(gong)、國防、科研、航(hang)天航(hang)空、家用(yong)電(dian)(dian)器(qi)元件等。
大(da)結(jie)晶電熔鎂砂(sha)產(chan)品特性(xing)(xing):純(chun)度(du)高(gao)(gao)、結(jie)晶粒大(da)熔、點高(gao)(gao)結(jie)、構致密;熱震穩定(ding)性(xing)(xing)好(hao);具(ju)有(you)(you)良好(hao)的高(gao)(gao)溫抗(kang)折強(qiang)(qiang)度(du);具(ju)有(you)(you)良好(hao)的抗(kang)渣性(xing)(xing)能(neng)和抗(kang)腐蝕性(xing)(xing)能(neng);導熱性(xing)(xing)能(neng)強(qiang)(qiang)、高(gao)(gao)度(du)絕緣(yuan)。
