从可能是造成耐火炉衬损坏的主要原因的参数出发进行了试验,发现镁碳砖的质量是最适于电炉和浇注钢包的渣线的采些生产条件的。现场试验结果大体上证实了理论上的研究。直接比较价格与寿命的结果表明,镁碳砖的质量是可以经济地加以应用。试验结果还表明,一般含有抗氧化剂的镁碳砖的质量比不含抗氧化剂的要好。试验进一步表明,没有必要采用高纯度的基体材料,因为它不会产生比低纯度材料更好的经济效果。 From the possible parameters that led to the failure of the refractory lining, the quality of the magnesia-carbon bricks was found to be the most suitable production conditions for the electric furnace and the slag line for ladle casting. Field test results generally confirm the theoretical research. The direct comparison of price and lifetime results shows that the quality of magnesia-carbon bricks can be economically applied. The test results also show that magnesia carbon bricks, which generally contain antioxidants, are better in quality than antioxidants. Experiments further show that it is not necessary to use high-purity matrix materials because it does not produce better economic results than low-purity materials.
