91自拍視頻:烏蘭察布電熔鎂砂主要(yao)有三(san)(san)大種類；一、普通電(dian)(dian)熔(rong)鎂(mei)砂，二、低硅高鈣電(dian)(dian)熔(rong)鎂(mei)砂，三(san)(san)、大結晶電(dian)(dian)熔(rong)鎂(mei)砂；

1、普(pu)通電(dian)(dian)熔(rong)(rong)鎂(mei)砂產品主(zhu)要是選用(yong)47%以(yi)上含(han)量菱(ling)鎂(mei)石(shi)或(huo)輕燒鎂(mei)砂為主(zhu)要原料在電(dian)(dian)弧中高溫熔(rong)(rong)融而成。方鎂(mei)石(shi)晶粒大，結構致密，抗渣(zha)性強(qiang)，高溫體積穩定(ding)性優越。電(dian)(dian)熔(rong)(rong)鎂(mei)砂的主(zhu)要用(yong)途(tu)：電(dian)(dian)熔(rong)(rong)鎂(mei)砂主(zhu)要是用(yong)于堿(jian)性磚、含(han)碳制品和不定(ding)型耐火材料的良(liang)好(hao)原料。

2、低硅高(gao)鈣(gai)電(dian)熔(rong)鎂(mei)砂產品主要是(shi)(shi)選用(yong)低硅菱鎂(mei)石為(wei)原(yuan)料，經高(gao)溫電(dian)熔(rong)爐熔(rong)煉而成(cheng)的。其特點(dian)是(shi)(shi)鈣(gai)硅比大于 2 ，晶(jing)粒(li)發育充分，顆(ke)料體積密度大于 3.50g/cm3以上。低硅高(gao)鈣(gai)點(dian)熔(rong)鎂(mei)砂主要用(yong)于中(zhong)頻感(gan)應電(dian)爐熔(rong)煉、高(gao)錳鋼、不銹鋼、高(gao)鑼鋼、堿性磚、含碳制品和(he)不定型耐(nai)火材料的良好原(yuan)料。

3、大結(jie)(jie)晶電(dian)熔(rong)(rong)鎂砂生(sheng)產(chan)工藝：大結(jie)(jie)晶電(dian)熔(rong)(rong)鎂砂主要是選用(yong)(yong)(yong)精選的(de)(de)特級天然菱鎂石或優(you)質(zhi)高純輕燒鎂顆粒，在電(dian)弧(hu)爐(lu)中熔(rong)(rong)融制得(de)。該(gai)產(chan)品具有純度高，結(jie)(jie)晶粒大，結(jie)(jie)構(gou)致(zhi)密，抗渣性強，熱(re)震穩定性好，是一種(zhong)優(you)良的(de)(de)高溫電(dian)氣(qi)絕緣(yuan)材料，也是制作鎂磚(zhuan)，鎂碳磚(zhuan)及不定型耐火(huo)材料的(de)(de)重要原料。廣泛(fan)應用(yong)(yong)(yong)于(yu)冶金、化工、國防、科研、航天航空、家(jia)用(yong)(yong)(yong)電(dian)器(qi)元件等。

大(da)結(jie)(jie)晶電熔鎂砂產品(pin)特性(xing)：純度高(gao)、結(jie)(jie)晶粒大(da)熔、點高(gao)結(jie)(jie)、構致密；熱(re)震穩(wen)定性(xing)好；具(ju)有(you)良好的高(gao)溫抗(kang)折強度；具(ju)有(you)良好的抗(kang)渣性(xing)能(neng)和抗(kang)腐蝕(shi)性(xing)能(neng)；導熱(re)性(xing)能(neng)強、高(gao)度絕緣。
