草莓視頻下載app:常德電熔鎂砂主要(yao)有三大(da)種類(lei)；一、普通電熔鎂(mei)砂(sha)，二、低硅高鈣(gai)電熔鎂(mei)砂(sha)，三、大(da)結(jie)晶電熔鎂(mei)砂(sha)；

1、普(pu)通(tong)電(dian)熔(rong)(rong)鎂砂(sha)(sha)產品主要(yao)是選用47%以上含(han)量菱鎂石或輕燒鎂砂(sha)(sha)為主要(yao)原料在電(dian)弧中高(gao)溫熔(rong)(rong)融(rong)而成。方鎂石晶粒大(da)，結構(gou)致密，抗渣(zha)性(xing)強，高(gao)溫體積穩定(ding)性(xing)優越。電(dian)熔(rong)(rong)鎂砂(sha)(sha)的(de)主要(yao)用途：電(dian)熔(rong)(rong)鎂砂(sha)(sha)主要(yao)是用于堿性(xing)磚、含(han)碳制品和(he)不定(ding)型耐火材料的(de)良好原料。

2、低(di)硅(gui)(gui)高(gao)(gao)(gao)(gao)鈣(gai)電(dian)(dian)熔(rong)(rong)(rong)鎂(mei)砂(sha)產品主(zhu)要是選用低(di)硅(gui)(gui)菱鎂(mei)石為原料，經高(gao)(gao)(gao)(gao)溫(wen)電(dian)(dian)熔(rong)(rong)(rong)爐熔(rong)(rong)(rong)煉而成的。其(qi)特(te)點是鈣(gai)硅(gui)(gui)比大(da)于(yu) 2 ，晶粒發育充分，顆(ke)料體積(ji)密度大(da)于(yu) 3.50g/cm3以上。低(di)硅(gui)(gui)高(gao)(gao)(gao)(gao)鈣(gai)點熔(rong)(rong)(rong)鎂(mei)砂(sha)主(zhu)要用于(yu)中頻感應電(dian)(dian)爐熔(rong)(rong)(rong)煉、高(gao)(gao)(gao)(gao)錳鋼、不銹(xiu)鋼、高(gao)(gao)(gao)(gao)鑼鋼、堿性(xing)磚、含碳(tan)制(zhi)品和不定(ding)型耐火材料的良(liang)好原料。

3、大結(jie)晶電(dian)(dian)熔鎂(mei)砂(sha)(sha)生產(chan)工(gong)藝：大結(jie)晶電(dian)(dian)熔鎂(mei)砂(sha)(sha)主要是選(xuan)用(yong)精選(xuan)的(de)特級天然菱(ling)鎂(mei)石或優質高(gao)純輕燒鎂(mei)顆(ke)粒，在電(dian)(dian)弧爐(lu)中熔融制得(de)。該產(chan)品具有(you)純度高(gao)，結(jie)晶粒大，結(jie)構(gou)致密，抗渣性(xing)強，熱震(zhen)穩定(ding)性(xing)好，是一種(zhong)優良的(de)高(gao)溫(wen)電(dian)(dian)氣絕緣材料(liao)，也是制作鎂(mei)磚，鎂(mei)碳(tan)磚及不定(ding)型耐火材料(liao)的(de)重要原(yuan)料(liao)。廣(guang)泛應用(yong)于冶(ye)金、化工(gong)、國防、科研、航(hang)天航(hang)空、家用(yong)電(dian)(dian)器元件等。

大結晶電(dian)熔鎂(mei)砂產品特性(xing)(xing)(xing)：純度高、結晶粒大熔、點高結、構致密；熱(re)震穩定性(xing)(xing)(xing)好(hao)；具有良好(hao)的高溫抗折強(qiang)度；具有良好(hao)的抗渣(zha)性(xing)(xing)(xing)能(neng)和(he)抗腐蝕性(xing)(xing)(xing)能(neng)；導熱(re)性(xing)(xing)(xing)能(neng)強(qiang)、高度絕緣。
