Description
Technical field
The utility model relates to a kind of stuffing sand adding set of ladle nozzle, belongs to technical field of ferrous metallurgy.
Background technology
It is electric furnace and pneumatic steelmaking two kinds of methods that current international and domestic main flow makes steel the method for making steel taked in batches, no matter take which kind of steel-making scheme, molten steel all must be transferred to ladle (being commonly called as large bag) from converter or electric furnace, or takes to continuous casting after refining, or directly after Argon to continuous casting.During cast, the moment stuffing sand that steel ladle slide board is opened needs under the static pressure effect of molten steel, to flow out ladle along the mouth of a river, molten steel is taken advantage of a situation outflow, be called that ladle " is opened " certainly, otherwise the moment stuffing sand that slide plate is opened can not flow out along the mouth of a river under the static pressure effect of molten steel, molten steel can not flow out, then need to pass into purity oxygen by oxygen lance stuffing sand is boiled thus molten steel can be flowed out along the mouth of a river enter tundish, complete casting process.
But at present when the mouth of a river adds stuffing sand, usually strict operation scheme and suitable operation tool is not had, all manual hand manipulation, cause the working strength adding stuffing sand large, what operate is lack of standardization, random, the compactness causing stuffing sand to add is lower, and it is irregular that stuffing sand adds rear shape, have impact on ladle self-opening rate.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of stuffing sand that improves to add compactness, improves the stuffing sand adding set of the ladle nozzle of ladle self-opening rate.
The purpose of this utility model is achieved in that
The stuffing sand adding set of the utility model ladle nozzle, comprise adding and sand flat platform, the described top sanding flat platform that adds is provided with pulley fixing device, described pulley fixing device is fixed with and is located at its other fixed pulley, described fixed pulley is wound with steel wire rope, one end of this steel wire rope is fixed with and adds sand hopper, the other end of steel wire rope is around on steel wire rope collection cylinder, this steel wire rope collection cylinder is connected with decelerator by shaft coupling, described decelerator is connected with the output of motor by adhesive tape, described motor is also equipped with rotating gauge tap, described add sand hopper bottom opening and fix with a perpendicular long sleeve pipe, the bottom of described sleeve pipe is communicated with adding tube by adapter sleeve, the bottom of described adding tube is arranged at directly over the mouth of a river of steel ladle, the inwall at this mouth of a river is provided with brick cup, through hole in the middle of described brick cup is wide at the top and narrow at the bottom, the bottom of described adding tube to be inserted in positioning pipe and to be welded and fixed with it, the internal diameter of described positioning pipe is greater than the external diameter of adding tube, the two ends, left and right of described positioning pipe are close on the inwall of brick cup.
The beneficial effects of the utility model are:
The stuffing sand adding set of this ladle nozzle adds sand operation by mechanically actuated standardization, reduce labor strength, overcome large lack of standard, the randomness with operating of labour intensity that tradition adds sand operation, adding tube is fixed on the center at the mouth of a river by it simultaneously, be evenly distributed when center, the mouth of a river is added towards periphery when can ensure that stuffing sand adds, can prevent the residue above brick cup from dropping in stuffing sand, realizing stuffing sand adds clean, fine and close, prevent stuffing sand from oozing slag sintering, improve ladle and open and water self-opening rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the stuffing sand adding set of the utility model ladle nozzle.
Fig. 2 is the structural representation at mouth of a river place in Fig. 1.
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Wherein: add and sand flat platform 1, pulley fixing device 2, fixed pulley 3, motor 4, adhesive tape 5, decelerator 6, steel wire rope collection cylinder 7, shaft coupling 8, sleeve pipe 9, add sand hopper 10, steel wire rope 11, rotating gauge tap 12, adapter sleeve 13, adding tube 14, steel ladle 15, the mouth of a river 16, brick cup 17, positioning pipe 18.
Detailed description of the invention
See Fig. 1 to Fig. 3, the utility model relates to a kind of stuffing sand adding set of ladle nozzle, it comprises adding and sands flat platform 1, the described top sanding flat platform 1 that adds is provided with pulley fixing device 2, described pulley fixing device 2 is for being fixed at its other fixed pulley 3, described fixed pulley 3 is wound with steel wire rope 11, one end of this steel wire rope 11 is fixed with and adds sand hopper 10, the other end of steel wire rope 11 is around on steel wire rope collection cylinder 7, this steel wire rope collection cylinder 7 is connected with decelerator 6 by shaft coupling 8, described decelerator 6 is connected with the output of motor 4 by adhesive tape 5, rotating gauge tap 12 described motor 4 is also equipped with for controlling the receipts of steel wire rope 11 and putting, thus control the lifting adding sand hopper 10.
Described add sand hopper 10 bottom opening and fix with a perpendicular long sleeve pipe 9, the bottom of described sleeve pipe 9 is communicated with adding tube 14 by adapter sleeve 13, the bottom of described adding tube 14 is arranged at directly over the mouth of a river 16 of steel ladle 15, the inwall at this mouth of a river 16 is provided with brick cup 17, through hole in the middle of described brick cup 17 is wide at the top and narrow at the bottom, the bottom of described adding tube 14 to be inserted in positioning pipe 18 and to be welded and fixed with it, the internal diameter of described positioning pipe 18 is slightly larger than the external diameter of adding tube 14, the two ends, left and right of described positioning pipe 18 are close on the upper wider inwall of brick cup 17, and the tube wall of positioning pipe 18 has eight apertures, for weight reduction with ventilative.
