Description

Technical Field

[0001] This utility model belongs to the field of heating furnace technology, and in particular relates to a water-cooled steel feeding device that ensures the steel feeding position is horizontal. Background Technology

[0002] Currently, steel rolling mills use walking beam furnaces for billet heating, equipped with steel feeders to complete the steel feeding task. However, the following problems have been found during use:

[0003] 1. Due to the heavy steel feeding task and the involvement of hot delivery of continuously cast steel billets, the high frequency of steel feeding causes the steel feeding machine claws and support arms to be baked at high temperatures in the heating furnace during the steel feeding process, which is prone to deformation and reduces service life.

[0004] 2. Frequent and prolonged use of the steel feed roller conveyor leads to significant wear on some roller surfaces, making it easy for the billet to skew along the conveyor. During feeding, operators need to constantly adjust the billet using the feeding machine to ensure it is in the correct position, which severely affects feeding efficiency. If not adjusted, the billet's position will become increasingly skewed as it enters the heating furnace with the movement of the walking beam, making it impossible to exit the furnace normally. In this case, the furnace must be shut down for repairs, causing significant economic damage and prolonged downtime, which seriously affects the production line's efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a water-cooled steel feeding device that ensures the steel feeding position is horizontal. By designing a water-cooled conical arm section, the support arm point near the steel billet can be continuously water-cooled, extending the service life and strength of the steel feeding machine support arm. Through the design of the baffle mechanism, active position correction can be performed before steel feeding, ensuring that the steel billet enters the heating furnace at a straight position and ensuring the safety of the high-strength steel feeding machine support arm.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0019] Furthermore, a slag-blocking edge is fixed at the bottom edge of the front side of the baffle body, and the slag-blocking edge forms an obtuse angle with the baffle body.

[0020] This utility model has the following beneficial effects:

[0021] This invention, through the design of a water-cooled conical arm section, enables continuous water cooling of the support arm point near the billet, extending the service life and strength of the steel feeder support arm. The design of the baffle mechanism, combined with the telescopic support arm, allows for active position correction before steel feeding, ensuring the billet is parallel to the roller conveyor side plate during feeding. This guarantees the billet enters the heating furnace upright and without tilting, ensuring the safety of the high-strength steel feeder support arm. Simultaneously, the integrated cast-in-place foundation increases the positional stability of the hydraulic cylinder and baffle mechanism.

[0036] The lifting cylinder 201 is vertically positioned directly below the end of the cone arm section 402 near the lifting section 404.

The billet is lifted away from the roller table by the lifting edge 405 at the lifting section 404. The inner arm body 4 is moved a distance towards the outer frame 3 by the cooperation of the motor reducer 409, gear 410 and rack 403, thereby driving the billet to come into contact with the baffle body 203. The position of the billet is corrected to be parallel to the side of the roller table. The furnace door is opened. The cooperation of the motor reducer 409, gear 410 and rack 403 drives the inner arm body 4 and the billet to move into the furnace. After reaching the set position in the furnace, the oil cylinder 101 retracts to place the billet on the walking beam in the furnace. At the same time, the baffle body 203 and the inner arm body 4 are controlled to reset.
