Induction heating process of materials handling

In the induction heating process, such as quenching and tempering material handling, largely depends on the shape. Processing equipment can be divided into two kinds: designed for continuous workpiece cross section is rules, the following gause will explain several typical deal for you.A, continuous heating processingRules of cross section of the workpiece, such as round rod and tube, the material handling system is similar with the induction heating system. These systems include loading, feed and other equipment. The only major difference is that used for quenching, water cooling or austenitizing additional workbench, the following will discuss the establishment of the continuous induction heating processing line.Bar and the continuous heating shaft processingDue to the mass production, automation of artifacts such as axial heating processing by the induction heating process is complete. The device includes an automatic processing system, programmable controller and the optical fiber sensors. By the transmission system to the heating zone, workpiece by four head tilting cylinder system (abbreviation OHD) processing. Scroll drives associated with appetizers, make the workpiece rotation or linear movement. Once the artifacts into the system, optical fiber sensors to feel the location of austenitizing heating. This sensor can detect abnormal operation (such as improper feeding), and can automatically shut down.OHD system of quenching process, the frequency of the induction generator is usually 500.000 Hz or 3000-10000 Hz. In each case, a temperature controller automatically check the temperature of the workpiece is too high or too low, to prevent being inappropriate austenitizing workpiece through the system, if the appropriate function key heating, through a quenching ring, so that it is cooled to 90 degrees Celsius. In moving to the front of the drawing part form martensite. Fiber optical copper again aware of artifacts, began using low frequency (300 hz) current heating, because the temperature needed for tempering is about 400 degrees Celsius, or steel can still maintain the temperature of the magnetic permeability. Artifacts once again by automatic heating, tempering, from processing the workspace, this was taken to the grinding area.Continuous heating pipesThe biggest application of induction heating and quenching, tempering is used for oil well pipe and gas pipe. In a typical application, an assembly line to complete the whole process, on the assembly line, steel is austenitizing, quenching, tempering, and cooling at room temperature. In this system, the pipe of hot working is over, will be sent to the inlet side and sent to the conveyor belt. Each function will love you by austenitizing workbench (5 of coil) in rotation to ensure temperature uniformity, tilt the roller because of one part of the heating pipe, only to control the deformation.After austenitizing, pipe into the pipeline under a few feet of the quench ring, remove moisture, to temper the workbench, then pipe cooling section, continue to move to different rotation to ensure that its not ovality.Continuous hot working of metal plateUsing the induction heating process of a text plate of high speed, continuous hot working is also possible. Lateral induction heating is the most economical, in this method, the eddy current magnetic field and its orthogonal to produce steel. After heating, the plates were cut by air after quenching cold so dry. The assembly line, the material is cooling, into the horizontal line for other operation. Because of different measurement, production line and speed detection device. Its signal and a controller, it is to adjust the input power to maintain the required temperature.Second, the local separation artifacts hot workingIrregular shape or see artifacts usually cannot be continuous processing of local hot working. In these cases, the need for special fixed or heat treatment process. The most commonly used devices include special scan and single use equipment, rotary table and automatic device.The shaft quenchingSingle use and scanning equipment widely used in all kinds of shaft all or partial quenching process automatically. In a typical longitudinal sensor scans, two of the six workpiece automatically at a set of shaft. Then each function keys by a single scanner heating and quenching. Preset variable control scanning speed and quenching parts. Preset variables and control power, at the same time, control of quenching cycle and the rotation of the workpiece. Artifacts can then be automatically discharged, now to reduce the manual operation with automatic device.If vertical shaft together with automatic online processing without artificial operation, the level of shaft can be in alone or scanner internal processing. Each step a solution by the horizontal conveyor belt or axis type device into the machine. Shaft is pull in and clip on the four head rest. Three refers to the rotation of the shaft flange sandwiched between them, the end of the plywood fixed to the rotating frame. Flange level also has a framework, but it is only in the pick up and help in the initial placement operations, a flange clamp, it will retract. Shaft has been in the process of the whole machine working, until he had to unload it. After placement, shaft turn at the next table. Where the sensor and the workpiece in order to maintain gas gap alone get uniform heating and reduce the deformation. Plate at the end of the rotating frame automatically adjust thermal expansion when the workpiece is fixed when heated. After heating, the workpiece quenching area are real quenching. Fourth, also is the last work is another chilling, go out to the rest of the heat. Completion of these operations, shaft is walking type reclaimer moved to a conveyor belt, to turn it back to the fire area, is also based on the induction of or a gas furnace.Fully automatic horizontal shaft quenching method are also popular. These devices can load without help operators and the number of quench, fine design step type feeder and workpiece fixed makes this possible.Turn the wheelSmall workpiece automatic processing and widely used in the hot working machine is the rotary wheel. Artifacts into lifting compartment, salt inclined rail material. When artifacts into the rotary table, can design different supports to place the artifacts. In different phases of the processing, but also for maintaining the workpiece and the induction coil or nozzle (used to push the artifacts in the quenching area) it is very important to the precise distance between usually turntable in the first stage consists of a number of test instruments. It checks the incorrect placement and alternate work so that if there is a full damage to the coil.
