Heat treatment technology of round blade
Round blades are usually made of high-quality special steel. Now round blades are used in various industries and are very common. You must know that heat treatment is one of the most critical factors in addition to the choice of steel raw materials. To understand the luxurious use of round blades, it is necessary to first understand the heat treatment process of the lower round blades.
After the round blade is forged and roughed by a lathe, heat treatment is required. The commonly used heat treatments for round blades are salt bath heat treatment and vacuum heat treatment. No matter which heat treatment method is used, it is necessary to select different temperatures for different materials. For example, some materials can release the highest hardness when the tissue reaches 800 degrees, and some can release the highest hardness when they reach 1100 degrees.
When the selected round blade material reaches the highest hardness after heat treatment, it should be tempered. No matter what material the blade is tempered for at least 2-3 times, the performance of the blade can be fully delivered. If the number of tempering is less, it will be The tissue distribution in the blade is uneven and the blade is not easy to use. After two or three tempering, the round blade is placed in normal temperature air to cool, so that the heat treatment of the round blade is completed.
It should be remembered that whether it is a round blade or other blades, the hardness when used is obtained by tempering. Generally, the highest hardness is obtained after quenching and heating, and then the desired hardness of the round blade is obtained by tempering.
