1、普通電(dian)熔(rong)(rong)鎂(mei)(mei)砂(sha)(sha)產品主(zhu)要(yao)(yao)是選用47%以上含量菱(ling)鎂(mei)(mei)石或(huo)輕燒鎂(mei)(mei)砂(sha)(sha)為(wei)主(zhu)要(yao)(yao)原料(liao)(liao)在電(dian)弧中高溫(wen)熔(rong)(rong)融(rong)而成(cheng)。方鎂(mei)(mei)石晶粒大,結構致密(mi),抗渣(zha)性(xing)強(qiang),高溫(wen)體積穩(wen)定(ding)性(xing)優(you)越(yue)。電(dian)熔(rong)(rong)鎂(mei)(mei)砂(sha)(sha)的主(zhu)要(yao)(yao)用途:電(dian)熔(rong)(rong)鎂(mei)(mei)砂(sha)(sha)主(zhu)要(yao)(yao)是用于堿性(xing)磚、含碳制品和不定(ding)型耐(nai)火材料(liao)(liao)的良好原料(liao)(liao)。
2、低硅(gui)高(gao)(gao)(gao)鈣電熔(rong)(rong)(rong)鎂砂產品主要(yao)是選用低硅(gui)菱鎂石為(wei)原料(liao),經高(gao)(gao)(gao)溫(wen)電熔(rong)(rong)(rong)爐熔(rong)(rong)(rong)煉(lian)而成的。其特點是鈣硅(gui)比大于 2 ,晶(jing)粒發育充分(fen),顆料(liao)體積密度大于 3.50g/cm3以上。低硅(gui)高(gao)(gao)(gao)鈣點熔(rong)(rong)(rong)鎂砂主要(yao)用于中頻感應電爐熔(rong)(rong)(rong)煉(lian)、高(gao)(gao)(gao)錳鋼、不(bu)銹鋼、高(gao)(gao)(gao)鑼鋼、堿(jian)性磚、含碳制品和不(bu)定(ding)型耐火材(cai)料(liao)的良好原料(liao)。
3、大結(jie)(jie)晶電(dian)(dian)熔鎂(mei)砂生產(chan)工(gong)藝:大結(jie)(jie)晶電(dian)(dian)熔鎂(mei)砂主要是選(xuan)用(yong)精選(xuan)的(de)特級天然菱鎂(mei)石或優(you)質高(gao)純輕(qing)燒(shao)鎂(mei)顆粒,在電(dian)(dian)弧爐中熔融制得。該產(chan)品具有純度高(gao),結(jie)(jie)晶粒大,結(jie)(jie)構(gou)致密(mi),抗(kang)渣性強,熱震穩(wen)定(ding)性好,是一種優(you)良的(de)高(gao)溫電(dian)(dian)氣(qi)絕緣(yuan)材料,也(ye)是制作鎂(mei)磚,鎂(mei)碳磚及不定(ding)型耐火材料的(de)重(zhong)要原料。廣(guang)泛(fan)應用(yong)于冶金(jin)、化工(gong)、國(guo)防、科(ke)研、航(hang)天航(hang)空、家用(yong)電(dian)(dian)器元件等。
大結晶(jing)電熔(rong)鎂(mei)砂(sha)產品特性(xing)(xing):純度(du)高、結晶(jing)粒大熔(rong)、點高結、構致密;熱震穩(wen)定性(xing)(xing)好;具有(you)良好的(de)高溫抗折強度(du);具有(you)良好的(de)抗渣性(xing)(xing)能(neng)和抗腐蝕性(xing)(xing)能(neng);導熱性(xing)(xing)能(neng)強、高度(du)絕(jue)緣。
