The technological value of coking coal may usefully be discussed in terms of the coking potential. Attention focuses on the coking potential of clinkering coal—alone, in blends from enrichment plants, or in coking batch. Calculation of the batch composition on the basis of predictors of...
The prospects for replacing Kuznets Basin coal with local Sverdlovsk coal at Ural steel plants are considered. The coal characteristics are analyzed. Detailed prospecting is required to refine the rank assignment, ease of enrichment, and reserves of Sverdlovsk coal.
The optimum stability of coal cake is essential for producing good quality of coke in stamp charged coke making process. A suitable binder named as ‘X7’ was identified to improve the stability of coal cake, oven throughput, coke quality and reduce specific energy consumption for stamp charged...
The optimality of coking batch may be assessed on the basis of the coefficient K
opt(Vt). A method is proposed for determining K
opt(Vt) by means of petrographic and reflectogram analysis. This approach permits ongoing assessment of the optimal composition of the coking batch and prediction of...
The strength of some model binder-filler composites is investigated. Specifically, these composites consist of pitch with various fillers: anthracite, pitch coke, sand, and glass. The proportions of the components vary. The dependence of the composite’s strength on the filler/binder ratio may be...
The possibility of isolating organic kerogen from shale at low temperatures is demonstrated for the example of Volga fuel shale.
The influence of the gaseous medium (volatiles, inert gas, oxygen, and chlorine) on the carbonization of a composite consisting of carbon filler and binder is considered. The porosity, strength, structure, and other properties of the composite are discussed.
