Abstract

Existing criteria for optimal coke quality used in practice in batch formulation are reviewed. The chemical and petrographic parameters of the optimal batches are presented for various Russian coke plants and for the production of high-quality coke. It is found that the economic indices of blast-furnace operation—such as the coke consumption and productivity—depend more on the mechanical strength M₁₀ of the coke than on M₂₅. A cost–quality criterion is proposed for finding the optimal coke. In contrast to previous criteria, the cost–quality criterion is based on a model for M₁₀, ignoring M₂₅. That simplifies the calculations required to find the optimal batch.

优化焦炭质量和批次参数的新标准

摘要

回顾了批次配方中实际使用的最佳焦炭质量的现有标准。为俄罗斯各种焦炭厂和优质焦炭生产提供了最佳批次的化学和岩相参数。研究发现，高炉操作的经济指标——如焦炭消耗量和生产率——更多地取决于焦炭的机械强度M ₁₀而不是M ₂₅。提出了一个成本质量标准来寻找最佳焦炭。与以前的标准相比，成本质量标准基于M ₁₀的模型，忽略了M ₂₅。这简化了找到最佳批次所需的计算。
