Cel The aim of the research is to inject massive quantities of coal at the main tuyères of a blast furnace using cold blast with a very high oxygen content. This pig iron production system has numerous advantages which may be summarized as follows: - very low coke rate of around 200-250 kg per tonne of hot metal; - fuel diversification as a result of injecting some 375 kg of coal; - elimination of hot-blast stoves; - higher calorific value of the top gas: about 6 Kj/Nm 3 compared to 3 to 3.5 Kj/Mn3 for conventional operation with or without coal injection; - low silicon content in the pig iron; - improved blast furnace productivity; Program(-y) ECSC-STEELRES 7C - Medium-term guidelines (ECSC) "technical steel research", 1986-1990 Temat(-y) B - Reduction of iron ores Zaproszenie do składania wniosków Data not available System finansowania CSC - Cost-sharing contracts Koordynator CENTRE DE RECHERCHES METALLURGIQUES Wkład UE Brak danych Adres Rue Ernest Solvay, 11 4000 LIEGE Belgia Zobacz na mapie Koszt całkowity Brak danych
