Tubular furnace stainless steel capillary annealing furnace tubular annealing furnace copper wire annealing furnace disk round wire annealing furnace

  Four zone temperature control is adopted for the heating of tubular annealing furnace, which is heated by silicon carbide rod or spiral resistance wire
The heating temperature can reach 1150 ℃
The furnace core tube is made of high temperature resistant stainless steel 310S tube, which is arranged in a single layer along the length of the heating furnace
The annealed pipe passes through the furnace core tube and is heated, and the ammonia decomposition atmosphere is sent into the furnace core tube at the same time
The furnace body is a split structure, which is convenient for maintenance, good sealing, less heat loss and good thermal insulation In order to quickly cool the annealed stainless steel coil, the annealing furnace is equipped with a water-cooling box, and the stainless steel pipe is installed inside as the cooling pipe
The annealed pipe can obtain the supersaturated stainless steel solid solution through cooling, so as to meet the hardness and brightness required by the process
A special winding unit is set at the rear of the water cooling box
After annealing, the pipe can be taken up in disc type, and a hydrogen protection input device to prevent the oxidation of the inner hole of the pipe is set inside
While taking up, hydrogen is sent into the inner hole of the pipe for protection, so as to ensure the internal and external brightness of the annealed pipe
