Self uniform heating and hardening technology for grid

The invention discloses a self uniform heating and hardening technology for a grid. The technology comprises the following steps of material preparation, furnace entering, sealed heating, heat preservation hardening and furnace outgoing. In the above mode, the invention discloses a self uniform heating and hardening technology for the grid. The aerothermodynamics principle is used, cyclic heating is carried out on the grid through guiding exchange of cold and hot air, heat is automatically distributed uniformly, the grid hardening effects are good, demands on equipment is low, the hardening work efficiency is high, the process is simple and convenient, no individual heat cycle device is needed, and the energy consumption is low.
