Description

Technical Field

[0001] The present invention relates to the technical field of steel plate quenching processing, and specifically to an automatic solid solution production line for steel plates. Background Art

[0002] In the solid solution heat treatment of alloy steel plates, the solid solution heat treatment is to heat the workpiece in the solid solution furnace body and then take it out of the furnace and cool it in water. Moreover, the existing device cannot perform fully automatic processing, especially when placing the workpiece into the heating furnace or taking it out from the heating furnace, manual tools are required to pick it up and put it in. Therefore, not only is the processing efficiency slow, but also a large amount of manpower is required. In the patent application publication number CN 110616304 A, a solid solution furnace equipment and solid solution method are disclosed. Although it can heat and quench the workpiece, it mainly solves the problem that the workpiece will not oxidize during the solid solution process. However, the equipment process mainly relies on manual workpiece fixation to the workpiece support. After heating, the bottom plate of the furnace is pulled out and the workpiece is directly dropped into the quenching pool. Finally, the workpiece is manually lifted to complete the processing. Therefore, the device cannot realize fully automatic processing of the workpiece. Not only is the processing efficiency slow, but it is also not suitable for the processing of steel plates. The cooling water for quenching has no heat dissipation function and cannot be universally used. Summary of the Invention
