heat treatment process of hardness tester

This process is the final heat treatment process of the pinion and the ring gear. Usually the inspectors only test the HRC hardness tester for soft material, and then cut the sample for metallographic analysis,it is the level of martensitic, carbide grade, morphology distribution, it is retained for the austenite amount morphology, heart martensitic grade, and shore hardness tester meter is to test the penetration layer from the surface to hardness above the deep depth operation as a final inspection. However, from the accident analysis of the early, failure of the tooth shaft and the serious wear of the tooth, it was found that the physical hardness was lower than the hardness of the sample, especially in the deep carburizing. The reason is that the actual pinion, ring gear.The digital hardness tester is not cut off from the same block, nor it is pretreated by the same furnace. In this way, the original structure of the material and the sample before infiltration is different, and there is a certain difference between the microstructure  hardness meter after the infiltration, and more importantly, the entire surface area of the pencil hardness tester is due to the great difference between the placement of the workpiece and the carburized surface(chemical heat treatment absorption). 

The interfacial reaction of the process and the main factors is included for the concentration of each component of the infiltrating medium and the surface state of the workpiece, it is the surface shape, the surface area size, and the surface energy that have an extremely important influence on the chemical heat treatment process. the Leeb hardness tester is compared by measuring the rockwell hardness tester and the microhardness tester,it is combined with the metallographic analysis of the rubber shore hardness tester penetration layer, the cause of the quality problem can be found quickly and accurately. In addition to necessary process adjustments, accidents can be hidden before the assembly of the workpiece.

The hardness meter is measured to analyze and verify the process of medium and large-scale complex structure molds. This is a feed mold made of martensitic stainless steel and mainly used for the production of feed. There are 10,000 to 27,000 holes in the mold, and 10 tons of mixed feed powder per hour is extruded from the die hole area into pellets. Therefore, the critical control point of the quality and service life is the hardness and penetration of the area in the ring transducer. Due to the large size of the mold and the distribution of the holes on the outer circle, the test point is a curved surface. 

The distance between the hole is generally 3 to 4 mm. Under this condition,the Leeb hardness tester is used in a variety of applications and compactness. Convenient features can accurately test the actual hardness at the die hole. According to the measured hardness meter and the metallographic analysis of the test block, the process can be modified and developed more rationally, the material potential can be fully utilized, and the service life can be improved. For example, if a ring mold can produce 10 tons of feed in one hour, 100 tons of feed can be produced when the service life is extended by 10 hours, which will bring huge economic benefits to the enterprise.
