Design General Information
Steel is generally refers to a iron, steel rolling plete production cycle of metallurgical plants. Blast furnace steelmaking provide raw materials for workshop is the workshop.
The graduation design for the design of a topic of iron million tons of iron and steel (15%) iron casting 85% of the blast furnace process design, the design workshop, the main task of the blast furnace body design calculation, ingredients, system design, blast furnace roof equipment design, selection of air blower, blast design calculation, slag processing system and gas processing of iron and workshop layout design system, and on the part of the process.
The part of the BF includes the BF internal size calculation , the brick design, cooling system and BF construction design etc. The heat stove part inclube calculation of the thermic transfor of the heat stove ,the construction design, calculation of blower machine. These two parts are the main parts of the ironmaking design.
The other process includes the slag and hot meatal treating system ,air-balst and blowing system off gas treating system and the layout for transportation in the plant area.
Key words: blast furnace,calorifier,technological design, equipment.
