摘要： PURPOSE:To reduce the amt. of a binder, etc., used and to improve the productivity of sintering by rolling and briquetting raw materials for sintering flaked after compacting and kneading under vibration and by sintering the resulting minipellets and other raw materials with a sintering apparatus. CONSTITUTION:Raw materials for sintering on a belt conveyor 3 and a compacting medium are charged to a compacting, plasticizing and kneading space 30, where the raw materials are kneaded under 3-10g vibrating force (g is acceleration of gravity) and flaked. The resulting flakes are fed into a granulator 40, rolled and briquetted under 3-6g vibrating force to obtain tough minipellets. These mini-pellets are mixed with other raw materials and fed into a sintering apparatus 17, where a layer of the raw material mixture is dried with hot exhaust air fed from a preheating hood 50.

摘要： PURPOSE:To correct sinkage quantity according to the surface shape of bulk material onto which a grab bucket is landed so as to get the grab quantity to approach the target set grab quantity. CONSTITUTION:The landing of a grab bucket 1 onto the surface of bulk material is detected by a landing detector 14 to stop the grab bucket 1, and the present sinkage quantity S is computed by a sinkage quantity computing element 25 from the relation between the grab quantity W and sinkage quantity S by the description of the bulk material and also by the surface shape in the landing position of the grab bucket 1, on the basis of control deviation E between the actual grab quantity W up to the preceding time and the target set value WO. A support wire 5 is then delivered by the specified quantity by a sunk position controller 12 so as to sink the grab bucket 1 into the bulk material by the sinkage quantity.

摘要： PURPOSE:To improve the permeability of sintering raw material by granulating kneaded flake having plastic state from a kneading machine with a granular machine and cascade-controlling granule grain size in accordance with the permeability of the sintering raw material on a pallet. CONSTITUTION:Moisture is added to the sintering raw material to charge this into the kneading machine 5. Then, by using compact medium, exciting-compact kneading is executed with exciting force 3-10g (g: acceleration of gravity). The obtd. kneaded flake having plastic state is charged into an exciting cylindrical type granular machine 6. A cylindrical axis in this granular machine is inclined to the gradient in the range of + or -10 deg. angle and the exciting force is adjusted into the range of 3-5g and and the above raw material is rolling-pelletized and granulated while controlling grain size of mini-pellet. This mini-pellet is blended into the ordinary sintering raw material, and after re-granulating with a mixer, this is supplied into a DL-type sintering machine. Then, the permeability of the sintering raw material on the pallet is measured and compared with the preset permeability. Based on this difference, the grain size of the above mini-pellet is cascade-controlled. By this method, the permeability at the time of sintering is improved saving of power cost in a main exhauster can be executed.

摘要： PURPOSE:To reduce fluctuation of the deviation of stock and to stabilize the stock and the facility by loading material with a loading time corresponding to a scheduled delivering quantity. CONSTITUTION:A material tank 1 is split with splitting speeds V1-V5 through a split controller. Material is loaded with loading speed V into the material tank 1, where a loading tank and a loading time are controlled through a loading controller 5. Material stock in each tank is obtained based on the splitting speeds V1-V5, the loading speed V and a position (n') of loading tank. These measurements and operated values are inputted to a stock predicting controller. In such a manner, loading time, splitting speed and loading speed are determined and loading times for respective material tanks are determined corresponding to scheduled splitting quantity preset for respective material tanks.
