[0002] Cast steel parts refer to steel components manufactured through casting processes. The production process of cast steel parts involves pouring molten steel into a pre-prepared mold, and after cooling and solidification, forming steel components with the required shape, size, and performance. Heat treatment is required during the processing of cast steel parts.

[0003] A heat treatment device for cast steel parts (authorization announcement number: CN222455129U) uses the movement of a square pressure frame to press and fix the cast steel parts in the storage frame, so as to prevent the cast steel parts from shaking during heat treatment. However, in the above-mentioned heat treatment device, after the heat treatment is completed, the material is discharged, and only after the material is discharged can it be loaded for heat treatment again. This is not convenient for uninterrupted heat treatment operation, resulting in low heat treatment efficiency. Therefore, this utility model is proposed. Utility Model Content
