Composite steel high-frequency quenching method

Abstract

The invention discloses a composite steel high-frequency quenching method. A composite steel high-frequency quenching device is provided. The quenching device comprises a device body, wherein one sideof the device body is fixedly connected with a cooling box; one side of the cooling box is fixedly connected with a cleaning mechanism; a quenching mechanism and a smoke absorbing mechanism are arranged at the position, located over the cooling box, of one side of the device body; and the quenching mechanism is located in the smoke absorbing mechanism. The smoke absorbing mechanism is added in the device, high-temperature poisonous gas generated due to cooling in the metal workpiece quenching procedure process can be absorbed through the device, the situation that the high-temperature poisonous gas is diffused, and consequently the construction environment of workers is influenced is prevented, and harm to human health is reduced; meanwhile, an added transmission mechanism is matched witha clamping and fixing mechanism, and an annular gasket metal workpiece can be subjected to the quenching procedure; and compared with a traditional manual quenching procedure, the quenching efficiency is high, the probability of accidental injuries in the quenching process is reduced, meanwhile, continuous work can be conducted, and the work efficiency of the device is improved.

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
