What is the purpose of intermediate frequency quenching? What are the characteristics of intermediate frequency quenching equipment? -Kehua

In order to increase production, many factories will use intermediate frequency quenching equipment. For some laymen, they do not know what the purpose of intermediate frequency quenching is, nor do they know the characteristics of intermediate frequency quenching equipment. Today, Kehua Xiaobian will tell you the answer. The purpose of intermediate frequency quenching According to Kehua's editor, intermediate frequency quenching is a kind of surface heat treatment technology, which uses the induction current of intermediate frequency to rapidly heat the surface of the steel and then immediately cool it down. Intermediate frequency quenching is to place a metal part in an induction coil, the induction coil is connected with alternating current, an alternating electromagnetic field is generated, and an alternating current is induced in the metal part. Due to the skin effect, the current is mainly concentrated on the surface of the metal part, so the surface The highest temperature is followed by water spray cooling or other cooling under the induction coil. Since the heating and cooling are mainly concentrated on the surface, the surface modification is obvious, while the internal modification is basically absent, which can play a very special heat treatment effect. The purpose of intermediate frequency quenching Equipment The intermediate frequency induction quenching equipment is mainly composed of three parts: the intermediate frequency power supply, the quenching control equipment (including the inductor) and the quenching machine tool. The induction hardening method is a main surface hardening method in the modern machine manufacturing industry. It has a series of advantages such as good quality, fast speed, less oxidation, low cost, good labor conditions and easy realization of mechanization and automation. According to the size of the workpiece and the depth of the hardened layer to determine the appropriate power and frequency (can be power frequency, medium frequency and high frequency). The shape and size of the inductor mainly depends on the shape of the workpiece and the requirements of the quenching process. Quenching machine tools also vary according to the size, shape and quenching process requirements of the workpiece. For mass-produced parts, especially in automated production lines, special machine tools are often used. Generally, small and medium-sized factories use general-purpose quenching machine tools because of the large batches and small quantities of workpieces. The purpose of intermediate frequency quenching The characteristics of intermediate frequency quenching equipment 1. Adopt IGBT devices and components to purchase globally. 2. Adopt high-efficiency combined resonance technology. 3. Adopt low inductance circuit arrangement. 4. Adopt large-scale digital circuits. 5. Adopt more comprehensive and mature protection technology. What is the purpose of intermediate frequency quenching? What are the characteristics of intermediate frequency quenching equipment? I believe that under the introduction of the editor, friends who read the whole text carefully already have the answer in their hearts, and no longer know nothing about intermediate frequency quenching.
