Coal-dust fuel and blast-furnace production in Ukraine
Tóm tắt
The possibility of introducing coal-dust fuel at Ukrainian metallurgical plants is considered. The use of coal dust in blast furnaces at rates of 120 kg/t of hot metal immediately reduces coke consumption by 2.7 million t and natural-gas consumption by 1.2 billion m3. In addition, by compensation of the negative impact of coal dust on the technology, the time for conversion to blast-furnace smelting based on coal-dust fuel may be reduced to a year.
