The chopping blade is a tool used for processing files. It is generally made of M2 steel. It has to withstand huge friction during the working process, so it requires strong toughness and high hardness. In order to meet its working requirements, we usually use medium frequency induction heating power to quench and heat treat the chopping blade. The hardness after quenching is required to reach 62-65HRC. Everyone knows about chopping blades, but when it comes to its heat treatment process, very few people know about it. Today, the editor will briefly introduce to you the medium frequency heat treatment process of chopping blades.
The chopper blade uses a medium frequency induction heating power supply to first perform a preheating heat treatment of 850-870℃x40s/mm, then a heating heat treatment of 1190-1200℃x20s/mm, and finally a tempering heat treatment of 580℃x1h+550℃x1hx2 times. Heat treatment After completion, the hardness falls within the range required by the process.
The chopping blade uses a medium-frequency induction heating power source for quenching heat treatment. The grain size is controlled at 10.5-11 levels, and overheated structures are not allowed. It is rare that the hardness still exceeds 65HRC after tempering at 580℃. If it exceeds, tempering at 590℃x1h should be supplemented.
We all know that a key factor that determines the quality of workpieces is the quality of the heat treatment process. Therefore, it is very important to understand and master the heat treatment process of workpieces. Today, the editor briefly introduces to you the medium frequency heat treatment process of chopping blades. I hope you can apply it to your work.
