     Automotive  steering rack tooth surface hardening a direct impact on the quality of their useful life. The world generally use the longitudinal magnetic field induction heating induction heating quenching and complex magnetic field quenching of two ways. Domestic induction heating equipment adopts the former, due to induced magnetic field uniformity, resulting in tooth and tooth root induced current uneven, resulting in quenching temperature, hardness of hardened layer uneven; hardened layer thickness, deformation large; efficiency low seriously flawed. Composite magnetic induction heating method is the high-frequency current simultaneously in tooth and tooth root to generate longitudinal and transverse magnetic field, making the tooth root on the tooth surface and produce uniform induced currents to ensure good homogeneity of the heating temperature and high efficiency. Now there were only a handful of companies to spend huge amounts of money from abroad quenching complex magnetic induction heating equipment, most of the enterprises are still using a single magnetic induction heating quenching method, product quality, there are significant flaws.

    Zhengzhou Kechuang Electronics Co., Ltd., Zhengzhou Branch in accordance with market needs and successfully developed a rack tooth surface hardening compound magnetic induction heating equipment. The device has high efficiency, simple operation, quenching quality has reached international advanced level, and inexpensive, is China's automotive steering an ideal choice for manufacturing enterprises.
