The high vacuum system is used to provide a higher vacuum during tempering and improve the surface quality of the tempered workpiece. You can choose to rush into the mixed gas of nitrogen and hydrogen to improve the brightness of the workpiece after tempering. You can choose double-chamber oil quenching tempering furnace or high-pressure air-cooling tempering furnace to more effectively avoid secondary tempering brittleness.
The low temperature convection heating system can improve the furnace temperature uniformity and heating speed at low temperatures. The rapid cooling system can effectively improve production efficiency.
