前言随着钢铁工业发展、高炉、焦炉相继大型化,以区域配煤方针来扩大炼焦用煤资源已引起各方重视。我国30多年来基本以苏联萨保什尼可夫胶质层厚度测定为主指导配煤。主要以各单种煤胶质层厚度Y值为依据,参照挥发分制定配煤比,利用200Kg小焦炉作半工业性试验,以M_(40)和M_(10)作为焦炭的抗碎强度和耐磨指标,据此调整配煤比。长期实
Preface With the development of the iron and steel industry, blast furnaces and coke ovens have been large-scale one after another, with the principle of regional coal blending to expand the coking coal resources has drawn great attention from all parties. In the past more than 30 years, our country has basically guided the coal blending with the determination of the thickness of the Soviet Sapershnikov gummy layer. Mainly based on the Y value of the thickness of each single kind of coal, the semi-industrial experiment with 200Kg small coke oven was made with reference to the volatile content, and the crushing strength of M_ (40) and M_ (10) And wear indicators, adjust coal blending ratio accordingly. Long-term reality
