Stainless steel bright annealing equipment is a professional equipment, it can heat stainless steel pipe to high temperature in a short time, and quickly cool it under hydrogen protective atmosphere, so that the stainless steel pipe has a bright surface and excellent performance. What parts does this device consist of? let's have a look.

Induction heating power supply, which is the core part of the whole set of annealing equipment. It adopts advanced solid-state IGBT technology, which can automatically adjust the output power according to the load, making the power factor of the power supply up to 90%, and the efficiency up to 95%.

The induction coil is the key part of heating the stainless steel tube. It is made of multi-turn copper tube spirally wound. The softened water flows inside the copper tube, which can effectively cool the coil and prolong the service life of the coil. The induction coil can heat the stainless steel tube from room temperature to 1050°C in only ten seconds, with fast heating speed and uniform temperature.

The cooling tunnel is an important part of cooling the heated stainless steel tube, which consists of a rectangular tunnel filled with pure hydrogen. The stainless steel tubes conduct heat exchange with the hydrogen in the tunnel and transfer the heat to the outer graphite lining. Graphite bushings have high thermal conductivity and are cooled by external cooling water. In this way, the stainless steel tube can be rapidly cooled to below 100°C under the protection of hydrogen, avoiding oxidation and discoloration.

Circulating cooling system, which is a system that provides cooling water, uses a soft water circulation system, which can save water resources and reduce pollution. The soft water circulation system only needs to replace a small amount of soft water every year, which can reduce maintenance costs and protect the induction coil and graphite bushing.

Gas control system, which is the system for controlling the atmosphere, which provides pure hydrogen and argon to the stainless steel tubes. Each gas path is equipped with pressure reducing valve, pressure gauge, flow regulator and flow meter, which can stably control the pressure and flow of gas.

The temperature control system, which is a system for monitoring and adjusting the temperature, is equipped with an infrared thermometer at the outlet of the induction heating channel to measure the temperature of the stainless steel pipe. The thermometer is connected with the temperature display meter and the regulator, and the alarm temperature can be set to ensure that the heating temperature is within a reasonable range.

Man-machine control panel, which is the interface for operating and displaying equipment, uses high-precision PLC module control, and the operation logic is simple and easy to use. The man-machine screen has the functions of process parameter saving, temperature data recording, etc., which can conveniently view and manage the operating status of the equipment.
