Abstract:

The correlations between the factors of stability and moisture of blended coal, coal grain size composition and stamping frequency etc. of coal cake in the stamping cokemaking process are studied. The comprehensive analysis indicates that the coal cake stability expressed with the indexes of compressive strength and shear strength is more accurate. When the moisture of blended coal is controlled in the range from 9% to 11%, stamping frequency is about 5 and the fineness of blended coal is about 90%, the stamping cokemaking production  is more suitable. At this time the stability of coal cake is better.
