Continuous atmosphere protection annealing furnace equipment for metal components

Continuous atmosphere protection annealing furnace manufacturer: Analysis of common faults in annealing furnaces
Manufacturer of continuous atmosphere protection annealing furnace: Annealing furnace can change the structure of steel through heat treatment, thereby improving the performance of steel. Heat treatment can significantly improve the mechanical properties of steel and extend the service life of mechanical parts.
Appropriate heat treatment processes can eliminate various defects caused by hot working processes such as casting, forging, and welding, refine grains, eliminate segregation, reduce internal stress, and make the structure and properties of steel more uniform.
(1) Unify the chemical composition and microstructure of steel, refine grain size, adjust hardness, eliminate internal stress and work hardening, improve the workability of steel, and prepare the microstructure for subsequent quenching.
(2) The commonly used annealing operations in production include complete annealing, isothermal annealing, spheroidizing annealing, stress relief annealing, etc.
(3) Stress relief annealing is mainly used to eliminate residual internal stresses in castings, forgings, welded parts, cold stamped parts (or cold drawn parts), and mechanical processing.
Continuous atmosphere protection annealing furnace manufacturer: Analysis of common faults in annealing furnaces
Manufacturer of continuous atmosphere protection annealing furnace: 1. Reversing valve and shut-off valve components
After a malfunction occurs, an alarm prompt will appear at the top of the main monitoring screen. Based on the prompt content, the faulty equipment can be preliminarily determined. The specific alarms are as follows: V101 valve position alarm, V105 valve position alarm, heating section gas reversing alarm, heating section air reversing alarm, insulation section gas reversing alarm, and insulation section air reversing alarm. Among them, V101 valve is the heating section gas quick cut valve, and V105 valve is the insulation section gas quick cut valve. Each device consists of an action part and a valve position feedback part. The action part is operated by an electromagnetic valve with pneumatic components.
Troubleshooting: After the above alarm occurs, first check the color displayed on the main monitor screen of the alarm device to determine its status.
If the quick cut valve displays yellow and the directional valve displays red "X", it means the stroke is not in place. Check if the stroke is separated from the equipment. If not, turn on the travel switch, check if the cam in the travel is not in place, and adjust it appropriately to press the spring plate with a large arc.
If the quick cut valve or directional valve is displayed as one of red or green, it can be judged that its stroke is normal, and the key point of investigation is in the action part. When inspecting moving parts, observe whether one of the two plugs of the solenoid valve lights up on site. If both plugs do not light up, it is an electrical fault. Then, if one of the two plugs is connected, remove both plugs and use bright plugs to sequentially insert and remove the two solenoid valve sockets. If the cylinder does not move, it is a mechanical failure. If the cylinder moves, it is an electrical fault.
Manufacturer of continuous atmosphere protection annealing furnace: 2. Control valve section
The regulating valve can refer to its relevant temperature to determine whether the equipment is working properly. When a malfunction occurs, first turn off the working power supply inside the power control cabinet, open the on-site valve cover, confirm that the module inside the valve is not energized, and then use an internal hex wrench to rotate the valve body. If the rotation feels stuck, it is a mechanical fault; If the rotation feels smooth, it is an electrical fault.
Manufacturer of continuous atmosphere protection annealing furnace: 3. Simulation part
The simulation here refers to temperature, pressure, and flow rate, etc. Except for air manifold pressure and gas manifold pressure, other analog quantities are not involved in control.
