With the heavy chemical industry such as steel, machinery and chemical industry gradually shifting to developing countries, heat treatment plays an important supporting role in the revitalization and development of China's machinery manufacturing industry, and the development of machinery manufacturing industry will certainly drive the rapid development of China's heat treatment industry....

Reasonable use of induction heating equipment to reduce heat treatment deformation of workpieces and other influencing factors...

Eight processes: annealing process, normalizing process, quenching process, tempering process, surface quenching process, chemical heat treatment process, vacuum heat treatment process, special heat treatment process (laser, ion nitriding, PCD, CVD, ion plating, etc.) These eight processes, heat treatment is an expert!...

Heat treatment is actually a complicated process, and its concept is not well described. Many manufacturers use metal processing only for surface finish and shape processing. For example, rolling, forming, machining, and plating. These processing methods only process the workpiece with some appearance. Only the induction heat treatment of the workpiece can greatly improve the comprehensive mechanical properties of the workpiece....

In general, quenching, welding and other processes, the relative power can be selected smaller, the frequency is selected higher; tempering, annealing and other processes, the relative power is selected to be larger, the frequency is selected lower; red punch, hot forging, smelting, etc., need For a process with good diathermy effect, the power is selected more and the frequency is selected lower. Hardware tools 7. Material of the workpiece The relative power of the high melting point of the met...

In the current tool processing process, the induction heating process is compared, which has obvious advantages such as energy saving, environmental protection and safety....

Quenching heat treatment cooling medium, commonly used quenching medium is water, aqueous solution, mineral oil, molten salt, molten alkali and so on....

Heat treatment is an important process in our forging industry, and many of our heat-treated counterparts will encounter a variety of product problems. Today, the Haituo Power Plant is based on some examples of heat treatment misunderstandings that have been experienced by an old heat treatment plant manager for many years....

The quality of bearing quenching heat treatment is directly related to the subsequent processing quality, which ultimately affects the use performance and life of the parts. At the same time, heat treatment is the major energy consumption and pollution of the machinery industry....

In order to ensure the performance and quality of the welded components, improve the plasticity of the weld metal, eliminate or reduce the welding residual stress, prevent cracks, and heat-treat the welded components if necessary. According to the order of the heat treatment process and the welding process, the heat treatment of the welded component is often divided into three types: pre-heat treatment, post-heat treatment and post-weld heat treatment....
