Industrial surface heat treatment processes can be roughly divided into three categories: overall surface heat treatment, surface surface heat treatment and chemical surface heat treatment. Different surface heat treatment techniques are used for the same metal, which can achieve different arrangements and then have different functions. Let's take a look at specific issues to see what three methods are used for surface heat treatment:...

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;...

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....

I believe that friends who specialize in the metal heat treatment industry are not familiar with the heat treatment process, right? ! So what is cooling? What is the important role in the heat treatment process?...

The so-called metal heat treatment refers to a process in which a metal workpiece is heated to a certain temperature and then rapidly cooled by a medium such as water or oil....
