Abstract
A tilt-type water-quenching process for treating steel slag features that after the molten steel slag is poured in slag ladle and the slag ladle is transported to the water-quenching pool, the slag lalde is tilted for pouring the steel ladle in the pool slowly. Before the steel slag comes in water, it passes through the water curtain sprayed by granularizer to become particles. Finally, it is quenched in quenching pool. Its granular steel slag can be used as raw material of smelting iron of for road.
Description
Technical field
The present invention relates to technical field of smelting, is a kind of tilting type steel slag water quenching treatment method.
Background technology
The treatment process of slag normally in the steel melting furnace: the red slag of the fusion in the stove is poured in the slag ladle, then it is thrown on the slag field, treat that nature cooling back forms dried slag.The deficiency of this process for treating steel slag is: dried slag is piled into the mountain, and easy to clean can't not carried, and dried slag is an industrial refuse, to the place take and the pollution of environment is CR Critical problem.
Summary of the invention
The objective of the invention is, a kind of tilting type steel slag water quenching treatment method is provided, make this method have following advantage: it can make the slag recycling, and dried slag is deposited does not need big place, reduces environmental pollution, reduces labor strength etc.
The present invention for achieving the above object; be achieved through the following technical solutions; water quenching pool is set; cylinder is installed in the water quenching pool edge; in cylinder one side pelletizer is installed, after molten steel slag is poured in the slag ladle on the slag car, is transported to the water quenching pool place; hanger cooperates on suspension hook by windlass and the slag ladle; slag ladle is tilted, and after turning to certain angle, the guide arm of tumbling on the slag ladle falls within on the cylinder; making slag ladle is that the center rotates the slag of slowly tumbling in water quenching pool with the rotating shaft of cylinder again; simultaneously, the pressure water of pelletizer has sprayed the formation water curtain, makes slag enter granulation behind the water curtain; enter then in the water quenching pool, through shrend slag be seated in and deposit the slag field and get final product.The granulation baffle plate is installed at water quenching pool edge and cylinder relative position place.Pelletizer also can be made of number row water jet standpipe, and the nozzle of jet pipe is different angles with respect to horizontal direction and distributes, and the length difference of every row's jet pipe forms the multilayer water curtain.Pelletizer also can be made of number row water jet standpipe, and the angle of inclination of the relative horizontal direction of nozzle of every row's water jet standpipe is the 3-5 degree.Pelletizer also can be made of number row's water jet standpipes, the angle of inclination of the relative horizontal direction of nozzle of water jet standpipe be respectively 0 °,, 3 ° and 5 °.Pelletizer also can have water tank and number row's water jet standpipe to constitute, and water tank upper is offered water spouting nozzle, and number row water jet standpipe is installed in the water tank bottom, and the antetheca that water jet standpipe is installed on the water tank is skewed, the angle of inclination of the relative horizontal direction of nozzle of water jet standpipe be 0 °,, 3 ° and 5 °.The cylinder that uses in the inventive method can have two supporting piles, and locating shaft and rotor plate are installed in supporting pile top.Two guide arms of tumbling are installed on the container outer wall of slag ladle.
The present invention through type approval test as can be known, can reach following advantage: the slag after Water Quenching, granularity is little, the shape comparison rule, owing to contain technology desired raw material before the ironmaking, can make raw materials for production and recycle, and can do to pave the way and wait the material use, because the slag after handling can be done raw material and use, so need not take big place, free from environmental pollution, reduced working strength of workers simultaneously significantly.
Description of drawings
Embodiment
The treatment process of slag of the present invention is: at first slag is poured into slag ladle, it is transported to the indoor Water Quenching of carrying out again.Its treatment process is at the indoor water quenching pool 11 that is provided with; cylinder 6 is installed in water quenching pool 11 edges; in cylinder 6 one sides pelletizer 4 is installed; after molten steel slag is poured in the slag ladle 3 on the slag car 7; be transported to cooperating of hanger on the suspension hook of water quenching pool 11 places by windlass 1 and the slag ladle 3; make slag ladle 3 slag of tumbling; after turning to certain angle; the guide arm 13 of tumbling on the slag ladle 3 falls within on the cylinder 6; slag ladle 3 is that the center rotates the slag of slowly tumbling in water quenching pool 11 with the rotating shaft 12 of cylinder 6 again; simultaneously, the pressure water of pelletizer 4 has sprayed the formation water curtain, and slag is slowly flowed out by granulation behind the water curtain; enter at last in the water quenching pool 11; slag after shrend is seated in to be deposited the slag field and gets final product, and adopts conical screen to sift out varigrained slag as required, does different material and uses.The used various device division of the present invention is as follows: the granulation baffle plate 8 that install at water quenching pool 11 edges and cylinder 6 relative position places is sprayed onto on this plate through water curtain when being used to block slag and toppling over and falls in the water quenching pool 11.Pelletizer 4 is to be made of number row water jet standpipe, makes the relative horizontal direction of nozzle of jet pipe be the different angles distribution, and the length difference of every row's jet pipe forms the multilayer water curtain.The angle of inclination of the relative horizontal direction of nozzle of water jet standpipe be respectively 0 °,, 3 ° and 5 °.Pelletizer 4 also can have water tank and number row water jet standpipe to constitute, and water tank upper is offered water spouting nozzle, and number row water jet standpipe is installed in the water tank bottom, and the antetheca that water jet standpipe is installed on the water tank is skewed, so that jet pipe extends to the outer length difference of water tank, is convenient to form the multilayer water curtain.The angle of inclination of the relative horizontal direction of nozzle of water jet standpipe be 0 °,, 3 ° and 5 °.Cylinder 6 has two supporting piles, and locating shaft 14 and rotor plate 15 are installed in supporting pile top.2 is the windlasss of cranking arm among the figure, the 7th, and slag ladle, the 9th, dial hook device, the 10th, the plate of keeping off a car.
