STRATEGIES FOR THE PRODUCTION OF LOW SILICON AND LOW

The performance of a blast furnace is generally evaluated by the level of its productivity, fuel rate and the quality of the hot metal Superior quality hot metal with lower and lower silicon and sulphur contents is required for the production of quality steel through LD-CC route Low silicon and sulphur operation contributes not only to reduction of the heat required to reduce silica in the Blast Furnace - Industrial-Craft-Wiki,The Blast Furnace is a heat based machine using solely for the creation of Steel To create Steel with the Blast Furnace, input a source of Iron, such as Iron Ingots, Iron Ore, or Iron Dust, and also 6 Compressed Air CellsSTRATEGIES FOR THE PRODUCTION OF LOW SILICON AND LOW ,source of silica input into the blast furnace in India is coke ash, which accounts for 70% In a similar way, sulphur enters the furnaces through coke and due to higher coke rate in our furnaces, it is difficult to maintain basicity at the desired level RSP blast furnaces do not have high top pressure which can favour low silicon hot metal The input used eg
