എങ്ങനെ ഉപയോഗിക്കാം ഉയർന്ന ആവൃത്തിയിലുള്ള ശമിപ്പിക്കൽ ഉപകരണങ്ങൾ to improve the hardness of the axe blade?

The blade of the axe can be high-frequency quenched with water and air, first cooled with water, then pulled out, paused in the air for a few seconds, then re-entered in the water for a few seconds, then pulled out again, paused in the air for a few seconds, and so on. And so on until cooled to room temperature and room temperature.

The purpose of the axe blade quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then temper at different temperatures, which can greatly improve the strength, hardness and resistance of the steel. Grindability, fatigue strength and toughness to meet the different application requirements of various mechanical parts and tools. It can also meet the special physical and chemical properties of some special steels through quenching, such as ferromagnetism and corrosion resistance.
