Method for accurately predicting cold strength of coke by introducing coal rock components

The invention discloses a method for accurately predicting the cold strength of coke by introducing coal rock components. The method comprises the step of calculating the cold strength of the coke according to the following formulas: M40=61-0.615*sigma Vdaf*CD+0.466*sigma G, CD=(50.3-26.4*sigma R0)*sigma SI. According to the method, the prediction precision of the coke cold strength can be obviously improved, so that an enterprise can optimize the cost and improve the economic benefits of the enterprise under the condition of ensuring the coke cold strength. 本发明公开了一种引入煤岩组分精准预测焦炭冷强度的方法，方法包括依据如下公式计算得到焦炭冷强度：M40＝61-0.615*∑Vdaf*CD+0.466*∑G，CD＝(50.3-26.4*∑R0)*∑SI。本发明所述方法能够明显提高对焦炭冷强度的预测精度，从而使企业能够在保证焦炭冷强度的情况下，优化成本，提高公司经济效益。
