直接结合镁铬砖

直接结合镁铬砖DMK是以镁砂和铬铁矿为主要原料,经高温或超高温烧制而成。它具有优异的热震稳定性,抗渣性,抗过热性损毁性能,抗真空损毁性能。另外它的抗氧化-还原性能,耐磨蚀冲刷性能也较好。在真空冶炼环境下,或强氧化性气氛下,或超热液体强烈冲刷下,或强碱性渣液和碱度变化的渣液的侵蚀下,它的寿命仅次于再结合镁铬砖,但更为经济的炉衬材料。它被广泛地用在钢铁冶金窑炉(如RH真空装置,VOD钢包,AOD转炉,EAF电炉,转炉等)的工作衬或关键部位的安全衬,有色金属冶金窑炉(IC3转炉,SMITH炉,NORANDA炉,OUTOKUMP闪速炉,反射炉等)的工作衬,有时还用于化工,造纸等工业的窑炉工作衬砖。
