1、普通電熔(rong)(rong)鎂(mei)(mei)(mei)砂產(chan)品主(zhu)(zhu)要(yao)(yao)是選(xuan)用(yong)(yong)47%以(yi)上含量菱鎂(mei)(mei)(mei)石或輕燒鎂(mei)(mei)(mei)砂為主(zhu)(zhu)要(yao)(yao)原料在(zai)電弧中高溫熔(rong)(rong)融而成。方(fang)鎂(mei)(mei)(mei)石晶(jing)粒(li)大,結(jie)構致密,抗渣性強,高溫體積穩定(ding)性優越。電熔(rong)(rong)鎂(mei)(mei)(mei)砂的主(zhu)(zhu)要(yao)(yao)用(yong)(yong)途:電熔(rong)(rong)鎂(mei)(mei)(mei)砂主(zhu)(zhu)要(yao)(yao)是用(yong)(yong)于堿性磚、含碳制品和不定(ding)型(xing)耐火材料的良(liang)好原料。
2、低(di)硅高(gao)(gao)(gao)(gao)鈣(gai)電(dian)熔(rong)鎂(mei)(mei)砂(sha)產品主(zhu)要(yao)(yao)是選用低(di)硅菱鎂(mei)(mei)石為原料,經高(gao)(gao)(gao)(gao)溫電(dian)熔(rong)爐熔(rong)煉而成的(de)。其(qi)特(te)點(dian)是鈣(gai)硅比大(da)于(yu) 2 ,晶(jing)粒發育充分,顆料體積密度大(da)于(yu) 3.50g/cm3以上。低(di)硅高(gao)(gao)(gao)(gao)鈣(gai)點(dian)熔(rong)鎂(mei)(mei)砂(sha)主(zhu)要(yao)(yao)用于(yu)中頻(pin)感應(ying)電(dian)爐熔(rong)煉、高(gao)(gao)(gao)(gao)錳鋼、不銹鋼、高(gao)(gao)(gao)(gao)鑼鋼、堿性(xing)磚、含碳制(zhi)品和不定(ding)型耐火(huo)材料的(de)良好原料。
3、大結晶電(dian)熔(rong)(rong)鎂(mei)砂生產工藝:大結晶電(dian)熔(rong)(rong)鎂(mei)砂主要(yao)是選(xuan)用精選(xuan)的(de)特(te)級天(tian)然菱鎂(mei)石或優質高純輕燒鎂(mei)顆粒,在(zai)電(dian)弧爐中熔(rong)(rong)融制得。該產品(pin)具有純度高,結晶粒大,結構(gou)致密,抗渣(zha)性強,熱震穩(wen)定(ding)(ding)性好,是一種優良的(de)高溫電(dian)氣絕緣材(cai)料,也是制作鎂(mei)磚,鎂(mei)碳(tan)磚及不(bu)定(ding)(ding)型耐火材(cai)料的(de)重要(yao)原料。廣(guang)泛應用于冶金、化(hua)工、國(guo)防(fang)、科研、航(hang)天(tian)航(hang)空、家用電(dian)器(qi)元件等。
大(da)(da)結晶電(dian)熔鎂砂產品(pin)特性(xing):純(chun)度(du)高(gao)(gao)、結晶粒大(da)(da)熔、點(dian)高(gao)(gao)結、構致密(mi);熱(re)震穩(wen)定性(xing)好;具有良好的高(gao)(gao)溫抗折強度(du);具有良好的抗渣性(xing)能和(he)抗腐(fu)蝕性(xing)能;導熱(re)性(xing)能強、高(gao)(gao)度(du)絕緣。
