Heat treatment Fixture for industrial furnace, material frame, material rack, tray, shelf, mesh, etc. The materials of heat treatment tooling mainly include heat-resistant steel Cr25Ni20, 310S, 2520, 304, etc. As a heat treatment tooling, the following requirements must be met:
①It is convenient for hoisting, suitable for heating and cooling of the workpiece, and can prevent or reduce deformation;
②It can be used repeatedly, and the tooling itself will not be deformed after repeated heating, with less oxide scale and no failure;
③Easy to process and manufacture, and low cost.
Heat treatment Fixture is also called casting combination tooling. For larger workpieces of heavy machinery, such as main shaft, large gear blank, ring gear, marine rudder stock, etc., cast iron tooling is often used, which can be used for normalizing furnace, quenching furnace, tempering furnace , Annealing furnace, mesh belt furnace, continuous furnace, roller hearth furnace, vacuum furnace, multi-purpose furnace and other heat treatment fixtures. The same processing system for smaller workpieces, mild steel welding tooling can be used.
