Induction heating and quenching machine tool for spring steel wire for vehicle
Induction heating and quenching equipment can quench 6-12 mm spring steel wire with high pressure and high speed water jet quenching device and corresponding quenching process without cracking. The speed of the steel wire is 8-40 m/min. The surface hardness of the steel wire after quenching is 62-64, the hardness of the core is 60-62, and the grain size is 11-12. Grain refinement and martensite refinement are the main reasons for the significant increase in strength and plasticity of induction quenched and tempered steel.
Continuous induction heating austenitization and water spray cooling and quenching are performed using supersonic and intermediate frequencies. It is generally believed that when the mass fraction of carbon in the wire rod is greater than 0.3%, water spray cooling and quenching is easy to quench and crack. Therefore, the main contradiction to be solved in the quenching process is quenching and quenching cracking.
