The pin shaft is a kind of fastener, which will be affected by external forces during use, and the wear will be serious. It is necessary to enhance the strength, hardness, wear resistance, and fatigue resistance of the pin shaft surface. Pin shaft high-frequency hardening equipment is specially used to
Current status of hot assembly and hot removal process The workpiece is assembled and removed with interference, and the traditional process uses acetylene to bake or cook with oil to realize the interference assembly and disassembly. This is time-consuming and labor-intensive, pollutes the environment, and is not easy to grasp
High frequency induction heater operating specifications that should be paid special attention to in daily operation: There must be more than two people to operate the high-frequency induction heater, and the person in charge of the operation must be designated. Wear insulating shoes, insulating gloves, and other prescribed protective equipment.
Induction heat treatment began to be used in China in the 1950s when the process was called “high frequency quenching”.This new heat treatment process USES coil electromagnetic induction heating to quickly reach the quenching temperature of the workpiece, and then rapid cooling so that only the surface layer to obtain
1: different materials, different equipment, different process parameters, the organization, and quality after heat treatment are also different. Even if the material brand, equipment and process parameters are the same, due to different upper and lower limits of chemical composition content, upper and lower limits of heat treatment temperature, upper
When the carbon content of steel is 0.15% ~ 0.75%, the test data can be summarized as the following formula: HRC = 20+60[2 w (C) -1.3 W (C) 2] Where w (C) — carbon content of steel, if W (C) is 0.35%, 0.35 is substituted into the above equation; HRC
Generally speaking, the safety protection of medium frequency induction furnaces can be divided into the safety protection of furnace equipment and the safety protection of operators. This section describes only the safety measures for the device structure. 1. Cooling water system If power supplies, induction coils, water cables, etc., all
1. Stability and accuracy of induction power supply equipment 1) Power control accuracy of the equipment Usually, the induction heating power supply is output and controlled by the way of current and power. The output precision of the induction heating power supply directly affects the stability of induction heating. 2)
Induction brazing can be used to braze aluminum and aluminum alloy workpieces. Using suitable brazing fillers, the aluminum components will be quickly joined together under the action of induction heating. Compared to flame brazing, induction brazing is cleaner and safer. Recent advances in lower temperature aluminum braze materials have allowed
The lining used in induction melting furnace should be selected according to the smelting steel or smelting non-ferrous metal varieties Choose, for example, for some steel grades only suitable for smelting in an alkaline furnace, smelting high manganese steel grades in the acid furnace When gold, (Mn0) will combine with
