Has the following advantages: 1. the utility model has reasonable design, simple structure, strong practicability, smooth feeding and good stability, avoids feeding deviation and can greatly reduce the labor intensity of operators behind the furnace; 2. when the feeding is finished and the blowing-out equipment is needed to be overhauled, the operation handle rotates the chute straight plate to drive the chute inclined plate, so that the chute inclined plate can be rotated to a position far away from the furnace body side, and the furnace body rotation and the blowing-out equipment overhauling are not influenced.
Description
Technical Field
The utility model belongs to the technical field of steelmaking converter accessory, a chute device for steelmaking converter is related to.
Background
At present, alloy materials are required to be added for deoxidation alloying during smelting of a steel-making converter, redundant oxygen in molten steel is removed, and the content of alloy elements in steel is adjusted so as to reach the component range of the steel-making specification. During feeding, the carburant and the silicon carbide are packaged in small bags, the granularity is 5-10mm, the materials are thrown into a steel ladle manually by an operator behind the furnace, the distance is about 3-4 meters, 20-25 bags of the carburant need to be thrown into each steel furnace, each bag is 10 kilograms in weight, 4-5 bags of the silicon carbide are arranged, each bag is 20 kilograms in weight, the labor intensity is high, the phenomenon of throwing and scattering is easy to occur, the stable smelting of a steel-making converter is not facilitated, the alloy consumption is increased, and the quality of molten steel is influenced.
Disclosure of Invention
The utility model aims at providing a simple structure, reasonable in design can effectively reduce intensity of labour when adding the alloy material, avoid appearing throwing the chute device for steelmaking converter of unrestrained phenomenon.
The utility model discloses a technical scheme do: the device comprises a fixed seat which consists of a bottom plate and a fixed shaft and is fixed at the bottom of a converter rear fire door and window opening through the bottom plate; the method is characterized in that: the fixed shaft of the fixed seat is inserted into a shaft sleeve, and the upper part of the shaft sleeve is connected with the lower part of the straight chute plate through a shaft sleeve plate; two sides of the upper part of the straight chute plate are provided with side plates, and the rear part of the straight chute plate is provided with a rear plate; the front end of the chute straight plate is connected with the upper end of the chute inclined plate with the skirt board arranged on the two sides, and the outer side of the rear plate is connected with a handle through a connecting rod.
By adopting the structure, when the chute inclined plate is used, the handle is held, the chute straight plate rotates by taking the fixed shaft as the shaft through the connecting piece, so that the chute inclined plate is driven to rotate, and the position of the lower end of the chute inclined plate is adjusted to be aligned to a ladle. At the moment, staff behind the furnace pick up the carburant and the silicon carbide to place on the chute straight plate and push the carburant and the silicon carbide to the chute inclined plate, and under the action of the inclination angle of the chute inclined plate and gravity, the added materials can slide into the steel ladle through the chute inclined plate and react with molten steel in the steel ladle. The skirt plate plays a height limiting role, the phenomenon that materials are thrown and scattered partially is prevented, and after feeding is finished, the chute straight plate is rotated to drive the chute inclined plate until the chute side is far away from the furnace body side. The utility model has the advantages of as follows: 1. the utility model has reasonable design, simple structure, strong practicability, smooth feeding and good stability, avoids feeding deviation and can greatly reduce the labor intensity of operators behind the furnace; 2. when the feeding is finished and the blowing-out equipment needs to be overhauled, the chute straight plate is rotated by the operating handle to drive the chute inclined plate, so that the chute inclined plate can be rotated to a position far away from the furnace body, and the rotation of the furnace body and the overhauling of blowing-out equipment are not influenced; 3. through the utility model discloses add in raw material, can be with the alloy material direct addition steel on flowing, with the molten steel abundant contact reaction, reduce the loss, improve molten steel alloy yield 3-5%, improve the molten steel quality, create economic benefits for the enterprise.
