Vertical Aluminium Alloy quenching furnace
Surface quenching of this type furnace only heat treat the surface or part surface of the workpiece , so only change the surface tissue, while the inside and other parts still retain the original low hardness, high plasticity and high toughness.
Surface quenching is easy to achieve mechanization and automation. It is stable quality, small deformation, short heat treatment cycle, less expenses and low cost.
Vertical quenching furnace uses heat - resistant stainless steel for air duct, material rack is raised at high speed, only need 3-6 seconds to get into water channel. In the process of heating and heat preservation, there is a high strength convection fan in the furnace, and a strong convection circulation is formed in the furnace, which makes the furnace temperature uniform. The temperature difference of each point in the furnace can be controlled within 1¢J, so that the anneal material can obtain uniform physical and mechanical properties.
