Description

TECHNICAL FIELD

[0002] The heating furnace steel structure refers to a series of mechanical devices used for guiding and supporting the billets in and out of the furnace body in the heating furnace. These structures are crucial for ensuring the efficient and safe operation of the heating furnace. They not only need to withstand the physical pressure under high temperature, but also need to ensure that the billets can be accurately sent into the heating area and smoothly taken out after heating is completed. The design points of the heating furnace steel structure include ensuring sufficient bearing capacity, thermal stability, and precise cooperation with the furnace body.

[0003] The common steel structure includes a driving mechanism, a transmission mechanism and a roller shaft. When in use, the driving mechanism drives the rotation of the transmission mechanism, so that the rotation of the roller shaft can be driven by the transmission mechanism, so that the steel can be transported to enter the interior of the heating furnace. However, this method only drives the steel to move by the roller shaft when transporting the steel, which leads to the lack of limiting mechanisms on the left and right sides of the top of the roller shaft, and the problem of billet displacement caused by vibration or impact. This increases the safety hazards caused by inaccurate position and cannot meet the working requirements of the feeding mechanism. Therefore, a heating furnace steel structure is proposed. SUMMARY
