UHF welding machines, Qingdao Tianrun high frequency, ultra high frequency welding machines supplied by Run High Frequency Electric Co., Ltd. Qingdao days. UHF welding machines, Qingdao Tianrun high frequency, ultra high frequency welding machine Supply Qingdao Tianrun High Frequency Electric Co., Ltd. (www.gaozhoubo.com.cn) launched this new upgrade, the above picture is only for reference, please call this Tel pages or images on to obtain the latest information, contact: Yan Lidong. According to the frequency of the alternating current level of induction heating heat treatment can be divided into UHF, HF, super audio, frequency, frequency 5 classes. ① ultra-high frequency induction heating heat treatment used in the current frequency up to 27 MHz, the heating layer is extremely thin, only about 0.15 mm, can be used for surface hardening thin circular saws and other complex shape of the workpiece. ② high frequency induction heating heat treatment used in the current frequency is usually 200 to 300 kHz UHF welding machine use, the heating layer depth of 0.5 to 2 mm, can be used for surface hardening gears, cylinder liners, cams, shafts and other parts. ③ super audio induction heating current frequency used for the heat treatment is generally 20 to 30 kHz, for small modulus gear with ultra-audio frequency induction heating current, the heating layer substantially along the tooth profile distribution UHF welding machine, pure fire after use better performance . ④ heat induction heating current frequency used is generally 2.5 to 10 kHz, a heating layer depth of 2 to 8 mm UHF welding machine supply, and more for big modulus gear, larger diameter shafts and other parts of cold roll The surface hardening. ⑤ frequency induction heating heat treatment used in the current frequency of 50 to 60 Hz, a heating layer depth of 10 to 15 mm, can be used for surface hardening of large workpieces. Induction Hardening Machine's main role is to make the necessary workpiece positioning and movement. It should also be provided with means for quenching medium. Quenching machine can be divided into standard machine tools and special machine tools, the former for general parts, which applies to mass production of complex parts. Ultra-high frequency induction heating welding machine features a heat treatment in order to ensure the quality and improve the thermal efficiency of the heat treatment, must be based on the requirements of the workpiece shape, design and manufacture of structures appropriate sensors. Commonly used sensors outer surface of the heating sensor, the sensor bore heating, flat heating sensors, universal heat sensors, special type heat sensors, a single type heat sensors, heat sensors compound, melting furnace, etc. .
