Abstract

On the basis of a mathematical model, a linear relation is established between the coke characteristics determined in drum tests. Specifically, the relation between the abradability M₁₀ and crushability M₂₅ is as follows: M₁₀ = 100 – KM₂₅. Analytical methods show that K = 1.00–1.11. As an example, applications of the model are presented, and K is calculated for Russian and Spanish data. The basic model may also be applied to other measures of coke’s mechanical strength, as illustrated for the example of the Irsid indices I₁₀ and I₂₀. Ordinary regression in the analysis of statistical data for M₂₅ and M₁₀ proves less informative than the use of the relationship M₁₀ = 100 – KM₂₅. An approach is suggested for finding the physical basis of the linear relation between M₁₀ and M₂₅.

在焦炭的强度特性 M25 和 M10 之间建立线性关系

摘要

在数学模型的基础上，在转鼓试验中确定的焦炭特性之间建立了线性关系。具体而言，耐磨性M ₁₀与压碎性M ₂₅的关系如下：M ₁₀ = 100 - KM ₂₅。分析方法表明K = 1.00–1.11。作为示例，介绍了模型的应用，并针对俄罗斯和西班牙的数据计算了K。基本模型也可以应用于焦炭机械强度的其他测量，如 Irsid 指数I ₁₀和I _{20的示例所示}. M ₂₅和M ₁₀统计数据分析中的普通回归证明比使用关系M ₁₀ = 100 – KM ₂₅提供的信息更少。提出了一种方法来寻找M ₁₀和M ₂₅之间的线性关系的物理基础。
