This equipment uses 75% hydrogen + 25% nitrogen as the protective gas. Runs through the operating system (COS). Except for furnace loading and unloading, mobile inner cover and heating and cooling cover, the entire process equipment is automatically controlled.
The furnace shell is welded steel plate, reinforced with section steel, and connected to the top, which is convenient for hoisting with a crane. The lower part of the heating mantle is made of refractory and thermal insulation materials, as well as the molded fiber module, and the upper part is a felt layer. A sealing frame is enclosed at the bottom edge of the heating mantle to seal the heating chamber.
The heating hood combustion system includes several high-speed burners arranged along the circumference of the heating hood. The burner is automatically monitored by the stove's PLC process ignition system. The flame detector uses a UV sensor head. Each burner failure and flame error is recorded separately. You can manually disengage one burner, and the annealing process continues with one less burner. The heating process is protected by two monitoring loops: one is monitored by the PLC; the other is performed by a separate temperature monitor.
After selecting the annealing program, the operator can start the annealing program by transmitting the set values to the PLC of the furnace. Then, until the annealing is completed, the operator does not need to input any data or commands, and can easily call up important information directly on the display screen, so as to obtain an ideal observation of the status of the equipment. You can manually intervene in the system and change the auto-run routine without affecting performance.
The whole set of furnace is fully automatic PID control, with large processing volume, and the energy saving effect is up to 65% compared with the traditional type. The economic benefits are obvious.
