Abstract

The best available technologies for coke production in Russia and elsewhere are briefly analyzed and the most promising is selected, with a view to producing coke with high coke strength after reaction CSR from batch containing low-value coal. For the example of Severstal coke plant, it is shown that stamp charging of the coal batch increases the hot strength of coke by a factor of 1.14 relative to traditional gravitational charging and permits the use of up to 60% of low-value coal in the batch to produce coke with CSR no lower than 50%.
