Heat Treatment Method of High Carbon Chromium Bearing Steel
Bearing steel is called the king of steel by people in the steelmaking industry. High-carbon chromium bearing steel is a large type of bearing steel, and it is the most commonly used steel for manufacturing bearings and bearing parts. The most commonly used high-carbon chromium bearing steels are...
Introduction of Planetary Gear Heat Treatment Process
Gear reducer is a combination of reduction motor and large reducer. No couplings and adapters are required, and the structure is compact. The load is distributed on the planetary gears, so its carrying capacity is relatively high. The weight of the planetary gear transmission is generally proport...
Analysis of Material Selection and Heat Treatment Process for Gear Parts
Heat treatment of gear parts is a common heat treatment. The main function of gear parts is to transmit torque, adjust speed, and change the direction of movement. A pair of mutually meshing gears transmit power through the contact and sliding of the tooth surface, so the tooth root is subjected ...
Operation Precautions And Emergency Treatment Methods Of Vacuum Sintering Furnace
Vacuum sintering furnace refers to a furnace for protective sintering of heated objects in a vacuum environment. There are many heating methods, such as resistance heating, induction heating, and microwave heating. The sub-types of vacuum sintering furnaces include silicon carbide high-temperatur...
Solutions To Common Problems In Vacuum Systems
What to do if steam appears? First, in the process of vacuum drying in the electrical products industry, the vacuum system is required to be able to extract a large amount of water vapor and solvent in a certain pressure range, and at the end of the drying, a lower ultimate pressure must be reach...
Determination of the Average Grain Size of Metals in Heat Treatment
1. The Classification of Cut-off Point Method and The Matters Needing Attention In Its Application 1. 1 Matters Needing Attention in the Straight-line Intercept Method One or several straight lines, appropriate measurement grid length and magnification, ensure that at least 50 intercept points ca...
Effect of Heat Treatment and Sintering On the Structure and Properties of 410 Stainless Steel
410 stainless steel is a martensitic stainless steel, because it does not contain Ni, which is toxic to the human body, and has high hardness, strength and wear resistance. It has a wide range of applications in medical, aerospace, machinery manufacturing and other fields. The 410 stainless steel...
SiC Ceramic Sintering Technology
Sic is a typical stable compound bonded by covalent bonds. With its low dispersion coefficient, it is difficult to achieve densification by conventional sintering methods. It is necessary to add some sintering aids to reduce the surface energy. Or increase the surface area, and use a special proc...
Factors Affecting The Quality of Vacuum Brazing
Generally speaking, the brazing quality is not only related to the process parameters, but the following factors in production practice have a greater impact on the brazing quality. 1. Leakage Rate of Equipment When the equipment leaks, the parts will oxidize. When the leakage rate is much lower ...
Changes in Mechanical Properties During Tempering Heat Treatment
Tempering heat treatment is a heat treatment operation in which the workpiece is heated to a temperature lower than the critical point after quenching, held for a certain period of time, and then cooled to room temperature. The purpose of tempering heat treatment is to obtain the required stable ...
