Description

Technical Field

[0001] The present application relates to the technical field of feeding a thermal walking beam treatment furnace, and in particular to a walking device for a thermal walking beam treatment furnace. Background Art

[0002] With the rapid progress of modern society, the international community's demand for steel is doubling day by day. Continuous heating furnaces are widely used in current rolling production due to their high thermal efficiency. Among them, the walking beam heating furnace is a continuous heating furnace. It is a product of the development from one-stage to multi-stage to adapt to the sharp increase in steel. It is also the most widely used heating furnace.

[0003] The walking beam heating furnace usually uses a walking feeding mechanism to transport the material to the static walking beam in the walking beam heating furnace. The static walking beam is placed with steel billets to be heated of basically the same shape and size, and then the material is driven forward by the moving walking beam. Usually, the walking feeding mechanism includes two layers of steel structure, and the upper steel structure moves horizontally along the lower steel structure, such as Figure 1 As shown, in the prior art, the upper steel structure 2 and the lower steel structure 1 move through an arc-shaped copper block 3. During use, the upper steel structure 2 moves in direct contact along the lower steel structure 1, and the copper block 3 will be worn. After wear, the horizontal positions of the upper steel structure 2 and the lower steel structure 1 will be offset, thereby affecting the conveying effect. Frequent replacement of the copper block 3 leads to an increase in the use cost of the equipment, and the replacement process is relatively cumbersome, affecting the overall work efficiency.

[0004] After a detailed search, the applicant did not find any technical solution that could stably maintain the horizontal position between the upper steel structure and the lower steel structure.

[0005] In summary, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content
