Technical Field

[0001] The present application relates to the field of metallurgy, and in particular to a slag cleaning device for a cutting area of ​​a slab continuous casting machine. Background Art

[0002] The production process of continuously pouring high-temperature molten steel into ingots with a certain cross-sectional shape and certain size specifications is called continuous steel casting, and the equipment required to complete this process is called a continuous casting equipment set. The electromechanical and hydraulic integration of steel pouring equipment, continuous casting machine main equipment, cutting area equipment, ingot rod collection and conveying equipment constitutes the core equipment of continuous steel casting, which is usually called a continuous casting machine. The slab continuous casting machine is equipped with a slag ditch under the fan section and the casting roller. The main function of the slag ditch is to use slag flushing water to transport the protective slag residue, iron oxide scale, and cutting slag generated during the production process of the continuous casting machine to the vortex well. The slag in the flame cutting area is mainly the cutting slag generated when the cutting gun cuts the ingot. If the cutting slag is not washed away in time, it will accumulate into large pieces on the slag ditch, making manual cleaning difficult and bringing certain safety hazards.

[0003] However, with the different widths of the ingot, especially when cutting the ingot at or near the limit width, the slag flushing water cannot flush the slag and easily causes the accumulation of cutting slag on both sides of the slag groove, which brings certain troubles and hidden dangers to efficient production and safety. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a slag cleaning device for the cutting area of ​​a slab continuous casting machine, which can solve the technical problem of accumulation of cutting slag on both sides of the slag groove.

[0007] Furthermore, a mounting plate is provided in the slag ditch, and the end of the lateral water spray pipe is rotatably provided on the side wall of the mounting plate. A driving motor is provided on the side wall of the mounting plate along the length direction of the lateral water spray pipe, and the driving motor is used to drive the lateral water spray pipe to rotate.

[0027] The present application discloses a slag cleaning device for the cutting area of ​​a slab continuous casting machine, referring to Figure 1-4 , including a slag ditch 1. At the same time, the continuous casting machine is provided with a plurality of rollers 5. The slag ditch 1 is located directly above the plurality of rollers 5. When the slab is cut, the slag during cutting splashes and falls into the slag ditch 1. At the same time, a transverse water spray pipe 2 is fixedly installed in the slag ditch 1 along the horizontal direction. The transverse water spray is arranged along the length direction perpendicular to the slag ditch 1. A plurality of nozzles 21 are connected to the transverse water spray pipe 2 at intervals. The water outlet ends of the nozzles 21 are all provided with nozzles. The water spray direction of the nozzles 21 is toward the bottom of the slag ditch 1. When the slag splashes and falls into the slag ditch 1, the nozzles 21 spray water to wash away the slag to prevent the slag from accumulating at the bottom of the slag ditch 1.

[0028] At the same time, a mounting plate 11 is fixedly installed in the slag ditch 1 in the horizontal direction, and lateral water spray pipes 3 are arranged on opposite sides of the slag ditch 1 along the length direction of the slag ditch 1. The ends of the lateral water spray pipes 3 are rotatably supported on the side walls of the mounting plate 11, and a plurality of spray pipes 31 are connected to the lateral water spray pipe 3 at intervals. The water spraying direction of the spray pipe 31 is toward the side wall of the slag ditch 1. At the same time, a nozzle is also installed at the water outlet end of the spray pipe 31. When the slab of the maximum width is cut, when the slag splashes onto the side wall of the slag ditch 1, the spray pipe 31 sprays water toward the side of the slag ditch 1, thereby washing away the slag splashed onto the side wall of the slag ditch 1.

[0029] In addition, a driving motor is fixed to the side wall of the mounting plate 11 along the length direction of the lateral water spray pipe 3, and a coupling is fixedly installed on the output shaft of the driving motor, and the coupling is fixedly connected to the end of the lateral water spray pipe 3. When the driving motor is working, the driving motor drives the lateral water spray pipe 3 to rotate, so that the spray pipe 31 can spray a larger area of ​​the side wall of the slag ditch 1. In addition, the rotation directions of the two lateral water spray pipes 3 are arranged in opposite directions, so that the two lateral water spray pipes 3 can rotate to both sides of the slag ditch 1 at the same time, or rotate to the middle of the slag ditch 1 at the same time. In addition, a protective cover 111 is fixedly installed on the mounting plate 11, and the protective cover 111 covers the driving motor. The protective cover 111 can protect the driving motor.

[0030] In addition, the cross-section of the slag ditch 1 is trapezoidal, and an inclined steel plate 4 is arranged in the slag ditch 1. The opposite sides of the inclined steel plate 4 are fixedly connected to the inner walls of the slag ditch 1 on both sides. The transverse water spray pipe 2 and the lateral water spray pipe 3 are located directly above the inclined steel plate 4. When the water flushed out by the transverse water spray pipe 2 and the lateral water spray pipe 3 flushes away the slag, the water can be better flushed into the vortex well along the direction of the inclined steel plate 4 under the action of gravity.

[0031] The implementation principle of a slag cleaning device in the cutting area of ​​a slab continuous casting machine in an embodiment of the present application is as follows: when a slab of extreme width is cut, when slag splashes onto the side wall of the slag ditch 1, the spray pipe 31 sprays water toward the side of the slag ditch 1, and the nozzle 21 sprays water to wash away the slag at the bottom of the slag ditch 1, thereby preventing the slag from accumulating at the bottom and both sides of the slag ditch 1.

[0032] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
