A kind of compound steel high-frequency quenching method

Abstract

The invention discloses a method for high-frequency quenching of composite steel, which comprises high-frequency quenching equipment for composite steel. The quenching equipment includes a main body of equipment. A cleaning mechanism is fixedly connected, and a quenching mechanism and a smoke absorption mechanism are installed on one side of the main body of the equipment and located directly above the cooling box. The quenching mechanism is located inside the smoke absorption mechanism. By adding The flue gas absorption mechanism can absorb the high-temperature toxic gas generated by cooling during the quenching process of metal workpieces through this device, prevent its diffusion from affecting the construction environment of workers, and reduce the damage to human health. At the same time, the added transmission mechanism cooperates with the clamping and fixing mechanism The quenching process can be carried out on the metal workpiece of the ring gasket, and compared with the traditional manual quenching process, the quenching efficiency is high, and the probability of accidental injury during the quenching process is reduced. At the same time, it can work continuously and increase the working efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of quenching, in particular to a high-frequency quenching method for composite steel. Background technique [0002] High-frequency quenching refers to a heat treatment method that uses high-frequency current to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece to a certain depth, and the core basically maintains the structure and performance before treatment. , so it can obtain the combination of high strength, high wear resistance and high toughness, and because of local heating, it can significantly reduce quenching deformation and reduce energy consumption. Widely used in the industry; [0003] High-frequency quenching equipment adopts induction heating. The engineer explained the principle of induction heating: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube that inp...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: 1. Traditional high-frequency quenching equipment is mostly aimed at cylindrical or square steel parts during use, and its push rod high-frequency quenching process After processing to make it meet the qualified conditions, but especially for the fastening gaskets used for fastening bolts of some large-scale equipment, in order to ensure sufficient rigidity during use, it also needs to be processed by high-frequency quenching process, so that it can be formed into pieces The fastening gasket can meet its use requirements when used. However, such steel parts cannot be processed by traditional high-frequency quenching equipment during the high-frequency quenching process. Usually, they are manually placed in the electromagnetic The high-frequency quenching and then cooling in the eddy current induction ring is not only time-consuming and labor-intensive, but also the processing efficiency of the workpiece is low, which cannot meet the production needs of the enterprise; 2. The fastening gasket used for fastening bolted joints of large equipment Since the processing of this kind of equipment still adopts the position of manual operation, it is undoubtedly very close to the high-frequency quenching equipment during the high-frequency quenching process of clamping the workpiece through the clamping equipment. Certain dangers, especially the toxic and harmful steam gas generated during the cooling process, will not only erode the human body and damage human health, but at the same time, the high-temperature steam generated during the cooling process will undoubtedly splash and scald workers, thereby endangering human health and affecting the working environment of workers. also pollute the working environment
