Online Solid Solution

EQUIPMENT COMPOSITION

The power supply system composed of IGBT transistor inverter medium-frequency power cabinet and channel compensation

capacitor cabinet - the bright solid melting system composed of induction coil, cooling water jacket, gas protection device and

infrared thermometer - the cooling system composed of water-water heat exchanger, external circulating water and cooling device

- as well as the welded pipe cleaning device and electrical control system.

TECHNOLOGICAL CHARACTERISTICS

The stainless steel pipes are heated to the required solution melting temperature (1040 ℃ for 304 material) by induction heating, and

then the solution melting treatment is carried out in a sealed device with hydrogen as the protective gas to improve the microstructure

of the weld seam and eliminate stress, thereby enhancing the corrosion resistance. Using hydrogen as the protective gas can make the

welded pipes after solution melting treatment bright and accelerate the cooling rate. The cooling of stainless steel welded pipes after

heating to the solution temperature adopts an indirect cooling method to keep the welded pipes bright.
