Abstract

A method is proposed for determining the technological value of coal concentrates on the basis of industrial coking data. The technological value serves as a numerical score characterizing the influence of a concentrate from a specific supplier on coke quality (that is, the cold strength M₂₅ and M₁₀, the hot strength CSR, and the reactivity CRI), taking account of the petrographic uniformity of the coal (σ_R). On the basis of serial coking, a close correlation is found between the technological value for the suppliers and \({{\sigma }_{{{{R}_{{{\text{co}}}}}}}}\). If the technological value is estimated from the coke strength and degree of petrographic uniformity, the concentrate suppliers may be divided into functional groups on that basis: when TV < 0.7, the concentrate is regarded as filler; when TV ≥ 1, the component is regarded as contributing to the coke quality.

通过连续焦化评估煤精矿的价值

摘要

提出了一种基于工业焦化数据确定精煤技术价值的方法。技术值用作表征特定供应商的精矿对焦炭质量（即冷强度M ₂₅和M ₁₀、热强度CSR和反应性CRI）影响的数字分数，同时考虑到岩相煤的均匀度（σ _R）。在连续焦化的基础上，发现供应商的技术价值与\({{\sigma }_{{{{R}_{{{\text{co}}}}}}} \). 如果从焦炭强度和岩相均匀度来估算技术价值，则可以将精矿供应商在此基础上进行功能组划分：TV < 0.7 时，将精矿视为填料；当 TV ≥ 1 时，该成分被认为对焦炭质量有贡献。
