Description

Technical Field

[0001] This utility model relates to the field of slab discharge, specifically to a pusher structure for a steel rolling heating furnace discharge machine. Background Technology

[0002] The main function of the tapping machine in a steel rolling furnace is to lift and pull out the heated slab from the furnace during the tapping process, placing it centrally on the tapping roller conveyor. The roller conveyor is responsible for transporting the slab to the rolling mill. First, the slab reaches the tapping position at the furnace door. Upon receiving the tapping signal, the furnace door rises, the tapping machine extends into the furnace, lifts the slab, then retracts to its final position, and the tapping machine lowers. The slab is then placed on the roller conveyor.

[0003] This method currently has several problems:

[0004] 1. During the tapping process in the heating furnace, slabs often tap at an angle.

[0005] 2. When the slab tilts, the operator often needs to make manual adjustments.

[0006] 3. This process for handling slab deviation involves numerous steps and a long processing time, requiring a high level of operator experience. Furthermore, if the processing time is too long, the slab temperature drops significantly, making further rolling impossible. Prolonged slab stagnation on the roller conveyor can also cause high temperatures in surrounding equipment, reducing equipment lifespan, triggering new malfunctions, and even leading to fires. Utility Model Content

[0007] The technical problem this invention aims to solve is that the slab is prone to tilting, and if the correction process takes too long, the slab temperature drops significantly, making rolling impossible. Prolonged slab stays on the roller table, which also causes high temperatures in surrounding equipment, reducing equipment lifespan, triggering new malfunctions, and even leading to fires.

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model is a pusher structure for the tapping machine of a steel rolling heating furnace, including a roller table, on which rollers are provided, and multiple sets of rollers are provided. It also includes a tapping machine, on which multiple sets of tapping bars are provided. The tapping bars transport slabs to be placed on the rollers, and each set of tapping bars is provided with a pusher.

[0009] Furthermore, the pusher head is configured in a triangular structure.

[0010] Furthermore, the height of the pusher head is slightly lower than that of the slab.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. Fewer operation steps, shorter processing time, and lower requirements for operator experience, effectively reducing processing time by 70%.

[0013] 2. The process involves few steps, short processing time, and low skill requirements for operators. It will not affect the continued rolling of the slab, thus extending the equipment's lifespan. Attached Figure Description

[0018] Among them, 1. Roller, 2. Steel bar, 3. Pusher. Detailed Implementation

[0019] As per the instruction manual Figures 1-3 As shown, this utility model is a pusher structure for a steel rolling heating furnace tapping machine, including a roller conveyor, on which rollers 1 are provided, and multiple sets of rollers 1 are provided. It also includes a tapping machine, on which multiple sets of tapping bars 2 are provided. The tapping bars 2 transport slabs to be placed on the rollers 1, and each set of tapping bars 2 is provided with a pusher 3.

[0020] As per the instruction manual Figure 4 As shown, the pusher head 3 is arranged in a triangular structure. The height of the pusher head 3 is slightly lower than that of the slab.

[0021] In practical use: When the slab tilts, the steel bar 2 only needs to push the slab forward from the lower position. When more than two pushers 3 can contact the slab, it means that the slab has been pushed straight. After the slab is straightened, the steel bar 2 is raised again and then retreats to the center position of the slab on the roller table.

[0022] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
