The advance well type vacuum annealing furnace series works by pre-vacuum atmosphere protection. When the furnace is pumped to a certain degree of vacuum, the furnace is filled with high-purity nitrogen or ammonia decomposition atmosphere for protection and heating, so as to achieve less oxidation. Heating, no decarburization and brightening. Due to the use of a stirring fan, the furnace has a high furnace temperature uniformity. The equipment is mainly used in the non-oxidative bright annealing of fasteners and standard parts industry.
Equipment Features:
The well type vacuum annealing furnace is made of high-quality insulation materials and refractory structure, which has good insulation performance and low energy consumption.
The temperature control adopts digital instruments imported from Japan, PID control, and high temperature control precision. The switching element adopts SSR (solid state relay, which is an upgraded product of thyristor, which has no sound, spark, and long service life)
