High Vacuum Heating Furnace 1600 degree 12L MoSi2 Heating
What is a high vacuum heating furnace ?
A high vacuum furnace is a type of furnace that is designed to operate under very low levels of pressure, typically in the range of 10^-3 torr or lower. The main purpose of a high vacuum furnace is to heat materials in a vacuum environment to facilitate various processes, such as sintering, brazing, annealing, and heat treatment. The low-pressure environment helps to prevent contamination of the material being processed, which can be critical for certain applications like electronic and aerospace components. Typical features of a high vacuum furnace include a vacuum chamber, heating elements, temperature controls, cooling systems, and gas handling systems.
High vacuum heating furnace features:
A. Good temperature uniformity, three-stage heating, computer temperature control, automatic PID adjustment;
B. External circulation air cooling system, high-efficiency heat exchanger, uniform cooling of the workpieces in all directions, fast cooling speed, uniform cooling;
C. Double heat exchanger structure; significant reduction in cooling time;
D. 300kg protective loading sintering furnace, the control box adopts fully mechanical drive, the material can stop at any position, reliable operation and easy maintenance.
