Description

Technical Field

[0001] This utility model relates to the technical field of fixed slag-blocking chain plates, and in particular to a fixed slag-blocking chain plate. Background Technology

[0002] In the metallurgical industry, after hot-rolled steel billets are heated, a layer of iron oxide is formed on the surface of the billets. Before entering the rolling mill, the steel billets need to be descaled by high-pressure water to remove the iron oxide from the surface. High-pressure water descaling is carried out while the steel billets are being transported by conveyor rollers. Protective boxes are installed before and after the descaling device to prevent water and iron oxide chips from splashing. However, during the descaling process, a lot of water and iron oxide chips still splash out from the inlet and outlet of the protective box. In order to reduce or prevent the splashing of a large amount of water and iron oxide chips, fixed slag-blocking chain plates are installed at the inlet and outlet of the descaling box. The slag-blocking chain plates can not affect the transport of steel billets and can effectively block water and iron oxide from splashing to the outside of the protective box. Utility Model Content

[0005] According to another embodiment of the present invention, the bottom of the chain suspension plate is provided with two sets of welded chain rings, each set of welded chain rings having several sets of parallel chains.

[0006] According to another embodiment of the present invention, the protective box has a cross-sectional area smaller than that of the phosphorus removal box, and is sealed and fixed to the phosphorus removal box by welding, with the middle connected to form a semi-enclosed space.

[0007] According to another embodiment of the present invention, the steel billet is placed on the roller conveyor and moves along its length inside the protective box and descaling box of the transport roller conveyor.

[0016] like Figure 1 This is a schematic diagram of the structure of this utility model, a fixed slag-blocking chain plate 2, characterized in that it includes a protective box 1, a slag-blocking chain plate 2, a descaling box 3, a conveyor roller 4, a high-pressure water supply pipe 5, and a steel billet 6; the protective box 1 is located at the front and rear ends of the descaling box 3, with the conveyor roller 4 passing through the middle; the top of the descaling box 3 is connected to the high-pressure water supply pipe 5; the steel billet 6 is placed on the conveyor roller 4; the protective box 1 is provided with several sets of rectangular holes 7, and the slag-blocking chain plate 2 is installed in the rectangular holes 7; the slag-blocking chain plate 2 includes a ring chain hanging plate 8 and an electric welded ring chain 9; the ring chain hanging plate 8 is fixed above the protective box 1, and the electric welded ring chain 9 is vertically installed at the bottom; the electric welded ring chain 9 is perpendicular to the direction of movement of the steel billet 6.

[0017] Specifically, the conveyor roller 4 supports and transports the steel billet 6 through the protective box 1, the descaling box 3, and the subsequent processing area in sequence; the slag-blocking chain plate 2 can block high-pressure water and iron oxide chips from splashing from the inlet and outlet, while not affecting the movement of the steel billet 6; the high-pressure water supply pipe 5 provides 15-25MPa high-pressure water, which is sprayed onto the surface of the steel billet through nozzles for descaling.

[0018] According to another embodiment of the present invention, the bottom of the chain suspension plate 8 is provided with two sets of welded chain rings 9, each set of welded chain rings 9 having several sets of parallel chains.

[0019] According to another embodiment of the present invention, the protective box 1 has a cross-sectional area smaller than that of the dephosphorization box 3, and is sealed and fixed to the dephosphorization box 3 by welding, with the middle connected, together forming a semi-enclosed space to block high-pressure water and iron oxide chips from splashing.

[0020] According to another embodiment of the present invention, the steel billet 6 is placed on the roller conveyor 4 inside the protective box 1 and the descaling box 3, and moves along its length direction.

[0022] The specific operation process is as follows: Step 1, conduct a system check, specifically checking whether the conveyor roller 4 is operating normally and ensuring that there are no debris on the roller surface obstructing the movement of the billet 6; check and confirm that the high-pressure water supply pipe 5 is securely connected, the pressure is adjusted to the range of 15-25MPa, and the nozzles are not blocked; check the installation status of the slag-blocking chain plate 2, whether the ring chain hanging plate 8 is securely welded to the top of the protective box 1, and whether the welded ring chain 9 hangs vertically with its lower end free and not tangled. Step 2, start the system, turn on the conveyor roller 4, and start the high-pressure water pump. Step 3: Steel billet transportation and descaling. Steel billet 6 is fed into protective box 1 and descaling box 3 by transport roller conveyor. High-pressure water (15-25MPa) is sprayed onto the surface of steel billet 6 to remove iron oxide. When the high-pressure water is sprayed onto the steel billet 6, a large amount of water and iron oxide chips splash in all directions. The descaling box 3 and protective box 1 block the high-pressure water and iron oxide chips from splashing outward in the inlet and outlet directions of steel billet 6 in the descaling box and protective box.
