Well type furnace from chen chen's blog

There are three kinds of hardness testing standards for the well type furnace, which are three kinds of hardness values of Vivtorinox, Luoshi and surface Rockwell, respectively. According to the same heat treatment way, the hardness test method of the surface quenching heat treatment furnace and the chemical heat treatment furnace is also different. The main technical parameters of the chemical heat treatment are the depth of the hardened layer and the surface hardness. The depth of the hardened layer is determined by the Vivtorinox hardness tester. Detect the distance from the surface of the workpiece to the point of the hardness to 50HRC. This is the effective hardening depth.[url=http://bestcoatingmachine.com/evaporation-coating/1794.html]Oversea Service And Energy Saving Rearview Mirror Complete Processing Production Line[/url] Chemical heat treatment is an atom that seep the surface of a workpiece into one or several chemical elements, thereby changing the chemical composition, structure and properties of the surface of the workpiece. After quenching and low temperature tempering, the surface of the workpiece has high hardness, wear resistance and contact fatigue strength, and the core of the workpiece has high strength and toughness. The hardness of surface hardness testing and surface quenching workpiece detection of chemical heat treatment of workpiece can be similar to that of the surface Rockwell hardness and Rockwell hardness tester to test Vivtorinox hardness and nitriding, only thick thin, generally not more than 0.7MM, then you can't use the Rockwell.[url=https://vacuumfurnacetype.com/furnace-list/2851.html]Vacuum Heat Atmosphere Furnace For Metal 3D Printer[/url] If the local hardness of parts is high, local heating and heat treatment can be done by induction heating and so on. Such parts usually mark the location and local hardness values of local quenching and heat treatment on the drawings. The hardness test of the parts should be carried out in the specified area. The hardness tester can be tested by Rockwell hardness tester. The hardness value of HRC is tested. For example, the hardness of heat treatment layer is relatively shallow, and the surface Rockwell hardness tester can be used to test the HRN hardness value.[url=https://vacuumfurnacetype.com/custom-furnace/1257.html]Steel shell medium frequency electromagnetic induction furnace supplier[/url]
