配入粘结剂生产优质焦炭的研究与应用

根据配煤炼焦原理、煤的成焦特性及粘结剂的性质,结合宣钢煤源情况,进行了在单种煤、配合煤中配入粘结剂的炼焦实验室研究、半工业生产试验研究,并成功应用于工业生产。与配粘结剂前相比,冶金焦冷强度、热性能指标得到大幅改善,取得了提高焦炭质量、大幅度降低成本的效果。

Study and Application of Blending Binder to Produce High Quality Coke

According to coal blending and coke-making principle, coke formation characteristic of coal and nature of binder and in combination with coal source situation of Xuanhua Iron & Steel Company, the coking experimental study and semi-commercial production test study with binder blended into single coal and coal blend is conducted, the study result is applied in industrial production. Compared with the result before binder blended, both metallurgical coke cold strength and thermal index are substantially improved, the effect of improving coke quality and substantial cost reduction are achieved.
