1、普(pu)通(tong)電(dian)熔(rong)(rong)鎂(mei)砂產品主(zhu)要(yao)(yao)是選用(yong)47%以上含量菱鎂(mei)石(shi)(shi)或輕(qing)燒鎂(mei)砂為主(zhu)要(yao)(yao)原(yuan)料(liao)(liao)在電(dian)弧中高溫熔(rong)(rong)融而成(cheng)。方鎂(mei)石(shi)(shi)晶(jing)粒大,結構致密,抗渣(zha)性(xing)(xing)強,高溫體積穩定(ding)(ding)性(xing)(xing)優越。電(dian)熔(rong)(rong)鎂(mei)砂的(de)主(zhu)要(yao)(yao)用(yong)途(tu):電(dian)熔(rong)(rong)鎂(mei)砂主(zhu)要(yao)(yao)是用(yong)于堿性(xing)(xing)磚、含碳制品和(he)不定(ding)(ding)型耐火材料(liao)(liao)的(de)良好原(yuan)料(liao)(liao)。
2、低(di)硅高(gao)鈣電(dian)熔(rong)鎂砂(sha)產(chan)品(pin)(pin)主(zhu)要是(shi)選用(yong)低(di)硅菱(ling)鎂石為原料(liao),經高(gao)溫電(dian)熔(rong)爐(lu)熔(rong)煉(lian)而成的(de)。其特點是(shi)鈣硅比大(da)(da)于 2 ,晶粒發育充分,顆料(liao)體積密度大(da)(da)于 3.50g/cm3以上(shang)。低(di)硅高(gao)鈣點熔(rong)鎂砂(sha)主(zhu)要用(yong)于中頻感應(ying)電(dian)爐(lu)熔(rong)煉(lian)、高(gao)錳鋼、不銹鋼、高(gao)鑼鋼、堿性磚、含碳(tan)制品(pin)(pin)和(he)不定型耐火材料(liao)的(de)良(liang)好原料(liao)。
3、大(da)結(jie)晶(jing)(jing)電(dian)熔(rong)鎂砂(sha)生產工(gong)藝:大(da)結(jie)晶(jing)(jing)電(dian)熔(rong)鎂砂(sha)主要是(shi)選用(yong)精選的特級天(tian)然菱鎂石或優質高純(chun)輕燒鎂顆粒,在電(dian)弧爐(lu)中熔(rong)融制(zhi)得(de)。該產品具(ju)有純(chun)度高,結(jie)晶(jing)(jing)粒大(da),結(jie)構(gou)致密,抗(kang)渣性(xing)強,熱(re)震穩定性(xing)好,是(shi)一種優良的高溫電(dian)氣絕緣材(cai)料,也(ye)是(shi)制(zhi)作鎂磚,鎂碳磚及(ji)不定型(xing)耐火材(cai)料的重要原(yuan)料。廣泛應用(yong)于冶金、化工(gong)、國防、科研、航(hang)天(tian)航(hang)空、家用(yong)電(dian)器元件等(deng)。
大結(jie)晶電熔(rong)鎂(mei)砂產(chan)品特性:純度高、結(jie)晶粒大熔(rong)、點高結(jie)、構致密;熱震(zhen)穩定性好;具有良好的高溫抗(kang)(kang)折強度;具有良好的抗(kang)(kang)渣性能(neng)和抗(kang)(kang)腐蝕性能(neng);導(dao)熱性能(neng)強、高度絕(jue)緣。
