我矿是镁质碱性耐火材料的基地,生产各种冶金镁砂、制砖镁砂、镁砖等耐火材料。控制其中的杂质、确定品位,是使冶金炉长寿的重要环节之一。以前,对镁砂、镁砖化学成分的分析用的是化学分析法。鉴于光谱分析在分析速度及经济上比化学分析优越,所以我室开始试验以光谱分析法分析镁砂、镁砖的化学成分。经过一年的实践,现在我矿所生产的镁砂和镁砖满足了生产的要求。镁砂和镁砖中的杂质是SiO_2、Al_2O_8、Fe_2O_8、CaO、MgO、MnO_2、其合量范围:SiO_2 2.0~4.0%,Al_2O_8 0.7~3.0%,Fe_2O_8 0.7~3.0%,CaO 1.0~4.0%,MgO 85.0~92.0%,MnO_2 0.05%左右。所要分析的成分:SiO_2、Al_2O_3、Fe_2O_3、CaO、MgO,
Mine mine is a base of magnesia alkaline refractory, producing a variety of metallurgical magnesia, brick magnesia, magnesia brick and other refractory materials. Control one of the impurities, to determine the grade, is an important part of the longevity of the metallurgical furnace. Previously, the chemical analysis of magnesia, magnesia brick chemical analysis. Spectral analysis is superior to chemical analysis in terms of analysis speed and economy, so I began to test the chemical composition of magnesia and magnesia bricks by spectral analysis. After a year of practice, the magnesia and magnesia bricks produced by mine now satisfy the production requirements. The impurities in magnesia and magnesia bricks are SiO 2, Al 2 O 8, Fe 2 O 8, CaO, MgO and MnO 2 in an amount ranging from 2.0 to 4.0 percent of SiO 2, 0.7 to 3.0 percent of Al 2 O 8, 0.7 to 3.0 percent of Fe 2 O 8, 1.0 to 4.0 percent of CaO, MgO 85.0-92.0%, MnO 2 0.05% or so. The components to be analyzed: SiO 2, Al 2 O 3, Fe 2 O 3, CaO, MgO,
