When using heat-treated trays baskets, the material should be ZG40Gr25Ni20 electrode, which has good creep performance during quenching will cause serious deformation cracking of the spreader the basket. Perform a high temperature before use Tempering, temperature control above 950 degrees, heat preservation for 1-2 hours, cooling with furnace, mainly to eliminate internal stress during casting increase product life.
The heat treatment tray basket is mainly composed of 2-4 single-layer heat treatment basket baskets, the basket is made by a casting process, is fixed by a fixing rod to form a whole, while ensuring sufficient Stability.
Heat treatment tray
It includes 2-4 single-layer heat treatment baskets. The single-layer heat treatment baskets are composed of two three-hole frames three two-hole frames are cast into an integrated structure. The single-layer heat treatment The material baskets are fixedly connected by fixing rods to form a heat treatment material basket, 8-10 concave grooves are provided on the two-hole frame.
The number of layers of the heat treatment tray material basket can be increased decreased according to actual needs, the parts can be hung on each layer of the crossbeam. The uniformity of the heating of the parts better guarantees the effect of vacuum heat treatment. Considering the high temperature environment during actual use, the heat treatment basket is made of high temperature resistant corrosion resistant steel, which greatly improves the service life of the basket.
