1、普(pu)通電(dian)熔(rong)(rong)鎂(mei)砂(sha)產(chan)品主(zhu)要(yao)是選用(yong)(yong)47%以(yi)上含(han)(han)量菱鎂(mei)石或輕燒(shao)鎂(mei)砂(sha)為主(zhu)要(yao)原(yuan)料(liao)在電(dian)弧中(zhong)高(gao)溫(wen)熔(rong)(rong)融而(er)成。方鎂(mei)石晶粒大,結構致密,抗渣性(xing)強(qiang),高(gao)溫(wen)體積穩(wen)定性(xing)優(you)越。電(dian)熔(rong)(rong)鎂(mei)砂(sha)的主(zhu)要(yao)用(yong)(yong)途(tu):電(dian)熔(rong)(rong)鎂(mei)砂(sha)主(zhu)要(yao)是用(yong)(yong)于(yu)堿性(xing)磚、含(han)(han)碳制品和不定型耐(nai)火材料(liao)的良好原(yuan)料(liao)。
2、低硅(gui)(gui)高鈣(gai)電熔(rong)(rong)鎂(mei)砂產品(pin)(pin)主要(yao)(yao)是選用(yong)低硅(gui)(gui)菱鎂(mei)石(shi)為(wei)原(yuan)料,經高溫電熔(rong)(rong)爐(lu)熔(rong)(rong)煉而成的。其特點是鈣(gai)硅(gui)(gui)比大于(yu) 2 ,晶粒(li)發育充分,顆料體積(ji)密度(du)大于(yu) 3.50g/cm3以(yi)上。低硅(gui)(gui)高鈣(gai)點熔(rong)(rong)鎂(mei)砂主要(yao)(yao)用(yong)于(yu)中頻感應(ying)電爐(lu)熔(rong)(rong)煉、高錳鋼、不(bu)銹鋼、高鑼鋼、堿(jian)性磚、含碳制品(pin)(pin)和不(bu)定型(xing)耐火(huo)材料的良好原(yuan)料。
3、大(da)結晶電(dian)熔鎂(mei)(mei)砂生產工藝:大(da)結晶電(dian)熔鎂(mei)(mei)砂主要是選(xuan)用精(jing)選(xuan)的特級天然(ran)菱鎂(mei)(mei)石或優(you)質高純輕(qing)燒鎂(mei)(mei)顆粒,在電(dian)弧爐(lu)中熔融制得。該產品具(ju)有純度高,結晶粒大(da),結構致密,抗渣性(xing)(xing)強,熱震穩定性(xing)(xing)好,是一種優(you)良的高溫電(dian)氣絕緣(yuan)材(cai)料,也是制作鎂(mei)(mei)磚,鎂(mei)(mei)碳(tan)磚及不定型耐火材(cai)料的重要原(yuan)料。廣泛應用于冶金、化工、國防、科研、航天航空、家用電(dian)器元件等。
大結(jie)晶(jing)(jing)電熔鎂砂(sha)產品(pin)特(te)性(xing):純度高(gao)、結(jie)晶(jing)(jing)粒大熔、點(dian)高(gao)結(jie)、構致(zhi)密;熱(re)震穩定性(xing)好(hao)(hao);具(ju)有(you)良(liang)好(hao)(hao)的高(gao)溫抗(kang)折(zhe)強度;具(ju)有(you)良(liang)好(hao)(hao)的抗(kang)渣性(xing)能(neng)(neng)和抗(kang)腐蝕性(xing)能(neng)(neng);導(dao)熱(re)性(xing)能(neng)(neng)強、高(gao)度絕緣。
