Annealing furnace for steel tube is a kind of heat treatment process which heats the metal workpiece to a certain temperature and then cools the metal workpiece at a suitable rate. The mechanical properties of annealed stainless steel pipe can be tested by tensile test or hardness test. A lot of steel is supplied by annealed heat treatment. The hardness of stainless steel pipe can be tested by Rockwell hardness tester and HRB hardness. For thin steel plate, steel strip and thin-wall steel pipe, the surface Rockwell hardness tester can be used to test the hardness of HRT.
The purpose of annealing is to improve or eliminate all kinds of microstructure defects and residual stresses caused by stainless steel pipe in casting, forging, rolling and welding, so as to prevent annealing deformation and cracking of stainless steel pipe.
2, soften stainless steel pipe annealing for cutting.
3. The medium frequency annealing furnace refines the grain and improves the microstructure to improve the mechanical properties of the metal workpiece.
4. Stainless steel pipe annealing is prepared for final heat treatment (quenching, tempering).
Medium frequency annealing furnace using imported motor, independent research and development of aluminum alloy fuselage, the use of lighter. Because of its exquisite design, automatic input and exit design, reliable overall performance and other advantages, the material is anti-corruption, the service life is more than 40 years, the medium frequency annealing furnace is made of high strength special steel exquisite welding, no corrosion, acid and alkali resistance, not easy to aging, not deformed. Therefore, it has been widely used in large steel plants, power plants and other industries, stainless steel pipe annealing treatment is not limited by space. According to the needs of users, the heating furnace is equipped with electric, mechanical and other different driving methods, which has the characteristics of high speed, low energy consumption, convenient disassembly and assembly, simple maintenance and so on. Stainless steel pipe annealing treatment should be widely used in petrochemical, pipeline engineering, steel structure engineering, aerospace and other fields.
