The wheel support shaft is a large-scale heavy-duty outer-circle variable-section induction hardening part. Its material is imported from Europe (part material according to European standard), its composition is close to domestic 35G steel, and the heat treatment requirements are very strict....

What is shaft heat treatment? The so-called shaft-type induction heat treatment in the industry generally refers to partial quenching of the shaft surface, the material is 45 steel or 40Cr, and the hardness of quenching can set the induction current and heating time according to the diameter of the material....

What is the heat treatment of the spline shaft? What is the purpose? The spline shaft is made of 42CrMo steel, and the processing flow is forging blank - quenching and tempering - machining - surface induction quenching - fine grinding - flaw detection - storage. The technical requirements for heat treatment are: tempering 266~311 HB, surface hardness of quenching part ≥52 HRC;...

Induction hardening technology has been widely recognized for its advantages of fast heating speed, high production efficiency, energy conservation, environmental protection, easy mechanization and automation, and has been widely used in the mechanical manufacturing industry, especially in the automotive industry....

10 methods commonly used in the quenching process of 2019...

What is the significance of quenching and tempering? Quenching and tempering treatment: The heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500-650 °C. Quenching and tempering can make the properties of steel and materials be adjusted to a large extent, and its strength, plasticity and toughness are good, and it has good comprehensive mechanical properties....

Why use induction heat treatment technology? In the metal heat treatment industry, traditional resistance furnaces and oil burners are still in use by some companies. However, some work, such as the drive wheels used in construction machinery such as bulldozers and excavators, have certain requirements on the mechanical properties of the various parts of the workpiece, in addition to the specific requirements for the material....

Why does the car universal joint need heat treatment? Today's cars take the overall layout of the engine front and front wheel drive, the front wheel is both the steering wheel and the drive wheel. As a steering wheel, it is required to be at its maximum...

The deformation of gears during heat treatment is a common phenomenon. There are many factors affecting the heat treatment deformation of gears, including: gear processing, materials and heat treatment processes. For these factors, Dongguan Haituo Power Plant has based on nearly 20 years of production practice experience. You have summarized the control methods for reducing the thermal stress distortion of gears and hope to help your metal heat treatment....
