We know that in order to improve the performance of Metal heat treatment is necessary, and heating is a very important process in the whole heat treatment process, and the final processing quality of metal heat treatment has a great influence on the heating process.
Heat treatment of all kinds of stainless steel after welding: after welding, the chromium element contained in stainless steel will diffusely precipitate and combine with carbon to form chromium carbide in the high temperature region (heat affected zone), which results in the reduction of local chromium composition and the inability to form protective film. Corrosion conditions, such as perforation, often occur in these heat affected zones, which can be remedied by heat treatment of objects after welding, which can cause chromium elements from other regions to diffuse to this chromium deficiency area to achieve protective effect.
Heating is one of the important processes of heat treatment. There are many heating methods for heat treatment of metals. Charcoal and coal are used as heat sources, and then liquid and gas fuels are used. The application of electricity makes heating easy to control and free of environmental pollution. These heat sources can be heated directly or indirectly by molten salt or metal or even floating particles.
This paper is organized by remote Electric customer Induction heating equipment.
