| Anshan Iron and Steel Company's blast furnace large scale is bigger and biger, which need more and more the pellet, Anshan Iron and Steel Company Bow Ore Company has completed two chain Grate-kiln machine - rotary kilns, which of production is 2,000,000 tons/years, the Anshan Iron and Steel Company Factory belt type machine ball group can produces 2,000,000tons/years,but Anshan Iron and Steel Company every year also import massive pellets ,which consumes massive foreign capitals.These pellets play the high and stable production role in the blast furnace iron-smelting production, the blast furnace iron-smelting production could not have the high quality pellet with the quite great degree the continuously supply.Anshan Iron and Steel Company's pellet production faced with giant gap.How to had the process carries on the excavation potential? How to have these erroneous zones in the daily industrial production? How to produce the part which in the pellet in the pellet theory and the industrial production has these to come apart? Through the present pellet theory thorough research, pointed out that we are in industrial production blind place, gived the instruction comment to the daily production.This topic is proposed in under above several aspect background.
