Vacuum furnace is in the vacuum near the state through the heating element of the industrial furnace, the industry is widely used in machinery, electronics, metallurgy and other industries. We all know that the usefulness of the vacuum furnace is very large, but many people certainly on the vacuum furnace is able to long-term development of doubt, here we come to tell you the development prospects of vacuum furnace.
Since the 80s of last century, foreign widely used high-pressure gas quenching instead of oil quenching, in order to avoid the cleaning process to improve the surface quality of the workpiece. The early 90s of last century, foreign countries have been developing (20 ~ 40) × 105Pa high-frequency hardening machine, the working pressure of 100 × 105Pa, the working temperature of 2200 ℃ high temperature and high pressure vacuum furnace, to the development trend of high temperature and pressure will continue The Vacuum furnace is widely used computer microelectronics technology and network technology, research and development of intelligent control system and network management system to achieve the vacuum furnace technology and equipment flexible and continuous operation.
To further improve the degree of automation and control accuracy, the main technical indicators: ① furnace temperature uniformity ≤ ± 3 ℃; ② inflation pressure 5 × 105Pa ~ 20 × 105Pa, argon-hydrogen mixed gas control cooling and recovery; ③ maximum heating temperature 2500 ℃; Pressure rise rate <6.67 × 10-1Pa / h; ⑤ vacuum degree of 10-2Pa ~ 10-4Pa.
