【摘要】 选取决定焦炭质量的主要指标———挥发分和粘结指数,运用二元线性回归的方法预测焦炭的强度。模型采用开滦集团单种煤及其配合的混煤和相应焦炭的数据,研究结果表明,运用此模型可以有效控制混煤的挥发分和粘结指数,保证焦炭的质量,检验配煤的合理性,以达到合理指导配煤炼焦的目的。更多还原

【Abstract】 Intensity of coke is predicted by use of binary linear regression method through selection of volatile and binding property as a main index for determining of coke quality.The data used in model is from single coal of Kailuan Group blending coal and its corresponding coking production.The research indicates that the model can be used to effectively control volatile matter and binding index of blending coal so as to ensure coke having required quality and to check the reasonability of coal blending for the aim of directing process of coking blended coal.更多还原
