Product details
Box type vacuum furnace, high-temperature energy-saving vacuum sintering furnace, atmosphere furnaceFurnace body: The furnace is built with mullite lightweight bricks, and the heating elements are arranged vertically for more uniform temperature. Sealing of furnace shell. To improve the service life of the sealing gasket, a circulating water cooling jacket is installed at the furnace entrance to reduce the temperature at the sealing point. At the end of the sintering process, the furnace can be pulled out of the furnace body, and the product can be rapidly cooled in a gas protected environment. The inlet is located at the front of the furnace, and after preheating in the heating chamber, it enters the furnace in multiple places. The exhaust is discharged through the front of the furnace top. Ensure a uniform atmosphere inside the furnace and reduce the temperature difference inside the furnace. Gas flow meters are installed on the gas path to control the flow rate of the atmosphere during normal use. High performance design, safety, reliability, and practicality all achieve ideal results.
