通过对各种煤系用性物的灰分、挥发分、粒度、比表面积及煤／惰比等因素对炼焦用煤粘结指数的影响进行综合试验，并与专用标准无烟煤所测得的粘结指数进行对比，找出了与标准无烟煤所测得的粘结指教有良好相关性的其它惰性物。将选出的煤系用性物和专用标准无烟煤同步测定了武钢焦化厂生产用煤的粘结指数，建立了二者的相关方程，确认了煤系用性物替代专用无烟煤的良好效果。 The comprehensive tests on the cohesive index of coking coal were carried out on the basis of the ash content, volatile content, particle size, specific surface area and coal / The index is compared to identify other inert materials that have a good correlation with the bonding advice measured with standard anthracite. The selected coal properties and special standard anthracite coal WISCO coking plant simultaneously measured the bonding index of the production of coal, the establishment of the correlation equation between the two, confirmed the use of anthracite coal anthracite good results.
