草莓視頻下載app:豐臺電熔鎂砂主要有三(san)大種類；一、普通電熔(rong)(rong)鎂砂(sha)，二、低硅高(gao)鈣電熔(rong)(rong)鎂砂(sha)，三(san)、大結晶電熔(rong)(rong)鎂砂(sha)；

1、普(pu)通電(dian)(dian)熔(rong)鎂(mei)砂產品主要(yao)(yao)是選用(yong)47%以上(shang)含(han)量菱(ling)鎂(mei)石或輕燒(shao)鎂(mei)砂為主要(yao)(yao)原料在電(dian)(dian)弧中高溫熔(rong)融而成。方(fang)鎂(mei)石晶(jing)粒大(da)，結(jie)構致密(mi)，抗渣性(xing)(xing)強，高溫體積(ji)穩定性(xing)(xing)優越。電(dian)(dian)熔(rong)鎂(mei)砂的(de)主要(yao)(yao)用(yong)途：電(dian)(dian)熔(rong)鎂(mei)砂主要(yao)(yao)是用(yong)于堿性(xing)(xing)磚、含(han)碳制品和(he)不定型耐火材料的(de)良好原料。

2、低(di)硅高(gao)(gao)鈣電熔(rong)(rong)(rong)(rong)鎂(mei)砂產品(pin)主要是選用低(di)硅菱(ling)鎂(mei)石為原料，經高(gao)(gao)溫電熔(rong)(rong)(rong)(rong)爐熔(rong)(rong)(rong)(rong)煉(lian)而成(cheng)的。其(qi)特點是鈣硅比大于 2 ，晶粒(li)發育充分，顆料體積密度大于 3.50g/cm3以上。低(di)硅高(gao)(gao)鈣點熔(rong)(rong)(rong)(rong)鎂(mei)砂主要用于中頻感(gan)應電爐熔(rong)(rong)(rong)(rong)煉(lian)、高(gao)(gao)錳鋼、不銹鋼、高(gao)(gao)鑼鋼、堿性磚(zhuan)、含碳制品(pin)和不定型耐(nai)火(huo)材(cai)料的良(liang)好原料。

3、大(da)結晶(jing)電(dian)熔(rong)(rong)鎂砂(sha)生產工藝：大(da)結晶(jing)電(dian)熔(rong)(rong)鎂砂(sha)主(zhu)要是(shi)選用(yong)(yong)精選的(de)(de)特級天然(ran)菱鎂石(shi)或優質高純(chun)輕燒鎂顆(ke)粒，在電(dian)弧(hu)爐中熔(rong)(rong)融制得(de)。該產品具有(you)純(chun)度高，結晶(jing)粒大(da)，結構致密，抗渣(zha)性強，熱震穩定性好，是(shi)一種優良的(de)(de)高溫電(dian)氣絕緣材料，也是(shi)制作鎂磚，鎂碳磚及(ji)不定型耐(nai)火材料的(de)(de)重要原料。廣泛應用(yong)(yong)于冶金、化工、國防、科研、航(hang)天航(hang)空、家用(yong)(yong)電(dian)器元件等。

大(da)結晶(jing)電熔鎂砂產品特性(xing)：純(chun)度高、結晶(jing)粒大(da)熔、點(dian)高結、構(gou)致密(mi)；熱(re)震穩(wen)定性(xing)好(hao)；具有(you)良(liang)好(hao)的高溫(wen)抗(kang)折強度；具有(you)良(liang)好(hao)的抗(kang)渣性(xing)能(neng)和抗(kang)腐蝕性(xing)能(neng)；導熱(re)性(xing)能(neng)強、高度絕緣。
