The integrated track with chain rail section is the track plate with meshing teeth, the trend is meshing with the driving wheel, and the track plate itself becomes the rolling track of the supporting wheel and other wheels. The material used for the track plate is mostly light weight, high strength, simple structure and cheap rolled plate. There are single tendons, double tendons, three tendons and so on.
The chain rail section is placed on the conveyor belt, and the feed speed of the conveyor belt is driven by a stepless DC motor. The chain rail section passes through the inductor, and is heated and quench. Early after quenching, caterpillar track section to the low temperature tempering tempering furnace, quenching machine tool of modern, the sensor technology has been adopted, its means of tempering or scanning, in order to ensure the tempering time, can be set to 2 back to the fire area, the purpose of tempering is to eliminate stress, because the caterpillar track about energy saving, modern tempering sensor also according to requirements, points of left and right type sensor. The disadvantage of scanning quenching method is that it is not easy to get a deep hardening layer, and it is easy to overheat the edge part of chain rail joint, so it is necessary to spray water or water gas mixture.
