Description

Technical Field

[0001] The utility model belongs to the technical field of converter technology in the iron and steel metallurgical industry, and particularly relates to an anti-sticking slag plate device for a converter. Background Art

[0002] Converter blowing is an intense autothermal process, the main purpose of which is to remove impurities from crude metals so that the target metal can be enriched. In this process, the formation and discharge of slag is inevitable. Slag is mainly composed of metal oxides and other impurities, which are separated from the molten metal during the blowing process and discharged from the converter through specific operations.

[0003] The slag discharged from the converter falls onto the slag plate, which is connected to the slag processing device. After falling onto the slag plate, the slag easily adheres to the surface of the slag plate. After a long period of accumulation, the slag accumulates on the slag plate, affecting the processing of the slag. Therefore, the problem of slag accumulation on the slag plate needs to be solved urgently. Utility Model Content

[0006] Furthermore, at least one baffle is provided on the upper surface of the slag chute along the length direction, one end of the baffle is fixedly connected to the slag chute, and the other end extends downward along the fixed connection point and forms an angle with the upper surface of the slag chute.

[0007] Furthermore, the angle is 15 to 30 degrees.

[0008] Furthermore, a compressed air nozzle is arranged under the baffle, the compressed air nozzle penetrates the slag chute, and the jetting direction of the compressed air nozzle is arranged along the extending direction of the baffle.

[0009] Furthermore, the compressed air nozzle is connected to an air compressor, and the air compressor provides an air source for the compressed air nozzle.

[0010] Furthermore, a pin shaft seat is provided on the side wall of the converter, and a pin shaft is provided on the upper end of the slag chute, and the pin shaft is rotatably connected to the pin shaft seat.

[0014] The utility model has the following advantages and technical effects:

[0015] 1. Significant anti-slag effect: The device cooperates with the shifting block and the rotating gear to make the slag plate move up and down under the drive of the rotating gear. This movement can effectively prevent the slag from sticking to the slag plate, allowing the slag to slide more smoothly, thereby ensuring the normal operation of the converter and reducing the equipment failure rate.

[0016] 2. Clever design and simple structure: The design of the slag plate fully considers the structural characteristics of the converter side wall, and the rotation connection of the slag plate is realized through the connection between the pin shaft and the pin shaft seat.

[0017] 3. Strong cleaning ability: By setting up compressed air nozzles and baffles, the airflow can be effectively used to blow off the slag on the slag plate, improving the cleaning effect. In addition, due to the design of the baffle, the airflow can be blown more concentratedly to the slag, further enhancing the anti-sticking effect.

[0018] 4. Easy operation and maintenance: The rotating gear in the device is connected to the motor, and the rotation of the rotating gear can be achieved by controlling the motor. The operation is simple and convenient. At the same time, due to the relatively simple structure of the device, it is also easy to maintain.

[0019] 5. Improve production efficiency: Since the device can effectively prevent the adhesion of steel slag, it reduces the time for cleaning steel slag, thereby improving the production efficiency of the converter. At the same time, since the equipment failure rate is reduced, the downtime in the production process is also reduced.

[0020] In summary, the utility model has shown remarkable effects in terms of anti-sticking slag, cleaning ability, ease of operation and improved production efficiency, and is of great significance for improving the operating efficiency of the converter and reducing production costs.

When the shift block 6 is inserted into the tooth gap of the rotating gear 1, the slag plate 3 is in the initial position, and the angle between the slag plate 3 and the side wall of the converter is 70 degrees; as the rotating gear 1 rotates, the shift block 6 is disengaged from the tooth gap of the rotating gear 1, and when the shift block 6 is opposite to the tooth tip of the rotating gear 1, the slag plate 3 is in the highest position, and the angle between the slag plate 3 and the side wall of the converter is 80 degrees.

[0028] At least one baffle 5 is arranged on the upper surface of the slag chute plate 3 along the length direction, one end of the baffle 5 is fixedly connected to the slag chute plate 3, and the other end extends downward along the fixed connection point and forms an angle of 15 to 30 degrees with the upper surface of the slag chute plate 3.
