We have all seen the hoe. It is a long-handled agricultural tool with a flat, thin blade that is mounted horizontally. It is specially used for cultivating, weeding, and loosening the soil around plants. During the working process, the hoe has to withstand huge friction and is usually required to have good toughness and wear resistance. For this reason, we often use a medium frequency induction heating machine to heat treat the hoe to meet its requirements. Today, the editor will briefly tell you about the medium frequency heat treatment process of hoe.
The heat treatment effect of hoes using medium frequency induction heating machine is quite good, and the heat treatment process is shown in the following table:
Steel number | Hardness requirementsHRC | Quenching temperature/℃ | Tempering temperature/℃ |
45 | 38-45 | 810-820 | 320-380 |
50 | 38-45 | 810-820 | 350-400 |
50Mn | 38-45 | 820-830 | 360-310 |
65 | 40-48 | 820-730 | 380-460 |
Q235 | 35-40 | 920-950 | 150-180 |
There are many commonly used agricultural tools. The editor simply introduces the intermediate frequency heat treatment process of hoes. After many manufacturers adopt the above process, the hoes produced meet their work requirements and the quality is quite good. If you want to know the heat treatment process of other agricultural tools, you can read more books on heat treatment, I believe you will gain a lot.
