CHARGE MIXTURE FOR PRODUCING COKE

摘要

The invention relates to charge mixture production for metallurgical coke. Increase of charge quality, decrease of ash content and improvement of its after-reaction strength are provided by using an oil coke additive in an amount of 50-70 wt% and coal concentrates of grades GZh - 7-10 wt%, GZhO - 12-20 wt%, G - 7-10 wt%, KS - 4-10 wt%. The charge mixture comprises 16-17% of volatile substances and has vitrinite index of reflection 1.8-2.4%.
