摘要
Abstract
The structure characteristics of the Direct Reduction Iron ( DRI ) shaft furnace discharging equip-ment has an important influence on discharging and materials smooth operation in the furnace , it directly affects the rationality and the economic benefit of DRI production process .Using the distinct element method software EDEM, the filling rates and solid material velocity of six different spiral discharging structures are studied in the work.The results found that the diameter of spiral blade , pitch and the angle of blade outside tangent with con-veyor main shaft in the feed zone have an influence on the filling rate and the velocity of solid material in fur -nace bottom.When the angle is 5°and the smallest pitch is 100 mm, the smallest material layer down velocity difference is 0.004 m/s, and the filling rates of the screw conveyor is 50%.This meet the requirements of the smooth operation in the shaft furnace .关键词
