Advantages and service life of heat treatment tray and basket

When using the heat treatment material tray and basket, the material shall be ZG40Gr25Ni20 welding rod. This brand has good creep performance during quenching, and will not cause serious deformation and cracking of the slings and basket. Before use, a high temperature tempering shall be carried out. The temperature shall be controlled above 950 degrees, maintained for 1-2 hours, and cooled in the furnace, mainly to eliminate the internal stress in the casting process and increase the service life of the product.

The heat treatment material tray and basket are mainly composed of 2-4 single-layer heat treatment material basket frames, and the basket frame is made by casting process, and is fixed with a fixed rod to form a whole, while ensuring sufficient stability.

Heat treatment tray and basket
It includes 2-4 single-layer heat treatment basket frames. The single-layer heat treatment basket frame is composed of two three hole frames and three two hole frames and is cast into an integrated structure. Each single-layer heat treatment basket frame is fixedly connected through a fixed rod to form a heat treatment basket. 8-10 concave grooves are set on the two hole frames.
The number of layers of the material basket of the heat treatment tray can be increased or decreased according to the actual needs, and the parts can be suspended on the beam of each layer. The beam is used to replace the bottom frame, which not only saves space and reduces costs, but also improves the uniformity of the parts in the heat treatment process, and better ensures the effect of vacuum heat treatment. Considering the high temperature environment in actual use, the material basket for heat treatment is made of high temperature and corrosion resistant steel, which greatly improves the service life of the material basket.
