Low carbon steel well type vacuum annealing furnace

The main composition and performance characteristics of low carbon steel pit vacuum annealing furnace: complete set of RQH type strong convection vacuum heating furnace body (including air cooling system), inner tank (including strong convection fan, air guide seat, and air guide tube , Sealed furnace cover), PID program control system, vacuum system, and gas-filled protective atmosphere system. Low-carbon steel pit vacuum annealing furnace adopts heat-resistant stainless steel wind hood, which is strictly sealed to isolate the workpiece material from the outside air. It is heated and insulated And during the cooling process, it is always under gas protection, so that the annealed material keeps the surface bright and non-oxidized. In addition, due to the high-strength convection fan in the furnace, the atmosphere in the furnace forms a strong convection cycle, which promotes uniform furnace temperature, and the temperature difference at each point in the furnace can be controlled within ±3℃, so that the annealing material can obtain uniform physical and mechanical properties.
