1. Overview < br Online bright annealing equipment can be well solved. Most of the solution treatment processes of stainless steel welded pipes use online black solid solution and pickling or offline bright solid solution, which brings environmental protection problems. The development of stainless steel pipe welding machines, especially industrial stainless steel pipe welding machines, is supported by national industrial policies, and the number of processes and costs increase.
2.Equipment composition < br The bright annealed stainless steel equipment is a power system consisting of IGBT transistor inverter intermediate frequency power cabinet and tank compensation capacitor cabinet-consisting of induction heating coil, cooling water jacket, gas protection device and infrared thermometer The bright solid solution system-a cooling system composed of a water-water heat exchanger and an external circulating water and cooling device-also has a welded pipe cleaning device and an electrical control system.
3 、 Technical characteristics < br The stainless steel pipe is heated to the temperature required for solid solution by induction heating (304 material 1040 ℃), and the solution is treated in a sealed device using hydrogen as a protective gas to improve the structure of the weld. Structure and eliminate stress to enhance corrosion resistance; using hydrogen as a shielding gas can make the welded pipe after solution treatment bright and accelerate the cooling rate. After the stainless steel welded pipe is heated to the solution temperature, it is cooled by indirect cooling to keep the welded pipe bright.
4. The schematic diagram of heating and cooling during the online bright solution treatment of stainless steel welded pipes is as follows
5. Work flow < br Bright bright annealing stainless steel equipment heats stainless steel welded pipes with induction heating coils to the temperature required for solid solution to complete the homogenization of austenite, that is, the solid solution process. The graphite cooling fixture at the inlet end of the water jacket 1 is rapidly cooled to reduce the temperature below 800 ° C to prevent the precipitation of carbon and chromium to maintain the solid solution effect. The cooling effect of indirect cooling always brings a small amount of precipitation of carbon and chromium, and the precipitation rate of chromium is slower than that of carbon, resulting in a chromium-depleted region (the chromium-depleted region is the main cause of intergranular corrosion). However, after the water jacket 1 is insulated between 550 and 750 ° C to provide a diffusion time for chromium, the chromium-depleted region can be eliminated. However, 550-750 ° C is a stainless steel sensitization zone. However, because the rapid cooling of the welded pipe of the graphite jacket of the water jacket 2 blocks the time effect of stainless steel sensitization, no sensitization result will occur. The temperature of the steel pipe cooled by the water jacket 2 should be lower than 130 ° C.
