Each element of steel has different effects on the depth of hardenability of auto parts. For the required hardenability of the automotive gear, it is possible to reach the depth of the top quenching test penetration of 18 or 14. Broaden a series of steel types and processes, and use In the direct normalizing, quenching and tempering process, the addition of elemental alloys and precise control of the alloy elements have greatly improved the chemical composition, microscopic structure and hardenability of the steel, enabling the production of a large number of t and traditional quenching. Tempered parts have the same strength of coupling, crankshaft and many other accessories. Furnace structure is very important to reduce energy consumption, so many improvements can be made on the production line. The effective thermal conductivity depends on the heat capacity determined by the insulator, heat source, furnace structure and size. It will greatly affect the quality, productivity and economy of the product. Further research will rely on the application of high-energy effective heat sources such as lasers, far-infrared rays, and advanced vacuum technologies. In order to make the heat treatment operation more flexible, Japan has used many small or single new furnaces, many new furnaces use ceramic fiber insulation materials, have less heat capacity, lower gas consumption due to the atmosphere and low pressure or vacuum in the furnace These stoves are designed and manufactured to meet energy saving and flexible production. Japan's low-load production systems are also used for heat treatment. For annealing and quenching, many small, flexible arrays of equipment and furnaces are installed. After the steel is directly forged or cooled after hot forging, the heat treatment step is not only less, but also the heat energy consumed during the heat treatment process is saved, so that the stored energy can be used for boiling water and cleaning, and can also be used as the surface modification in the cooling process as shown.
