Bright annealing furnace:
Furnace atmosphere to form convective circulation, effectively improve circulation uniformity of furnace temperature. Annealing work to ensure that the physical properties of uniform, because the device has a sealed inner cover, vacuum, filling protective atmosphere system, can effectively prevent the work surface oxidation, decarburization phenomenon , achieve  reliable light treatment.

Features:
1. forced convection air flow circulation, temperature uniformity, saving process time;
2. which leads to protection of the atmosphere, the workpiece without decarburization;
3. workpiece loading capacity large, high production efficiency;
4. configuration, cooling mask, through the blast and the water spray to speed up the cooling rate.
