由于粘土中各种氧化物杂质对其耐火度影响程度的不同 ,因此在粘土耐火度公式中 ,统用RO来表示各种氧化物杂质的总量 ,并乘以相同的因子系数 ,这样势必会造成用此粘土耐火度公式计算的耐火度与真实值之间存在着较大的偏差。本文针对粘土耐火度公式所存在的问题 ,提出了此公式的修正公式 ,通过实验验正与误差分析 ,表明该修正公式更具准确性和实用性。同时 ,作者对修正公式的适用范围也进行了讨论。
Due to the different degrees of influence of various oxide impurities on the refractory resistance in clay, in the formula of clay refractory, RO is used to denote the total amount of various oxide impurities and multiplied by the same factor, which is bound to be There is a big deviation between the refractoriness and the real value calculated by the clay refractory formula. Aiming at the existing problems of clay refractory formula, this paper presents a formula for the correction of this formula. Through the experimental verification and error analysis, it shows that the correction formula is more accurate and practicable. At the same time, the author also discussed the scope of application of the correction formula.
