摘要：
Operating experience since the first Soviet pulverised coal preparation and injection plant was commissioned in 1980 is considered. The technology developed for injecting 60-80 t pulverised coal/t hot metal together with natural gas at a high degree of oxygen enrichment of the blast has contributed to a 22.3% reduction in coke rate, the reduction in overall fuel consumption in terms of standard fuel being 8.8%. Substantial economic benefits have been obtained.
