[0002] Cemented carbide roll rings (also called tungsten carbide roll rings) refer to rolls made of tungsten carbide and cobalt as materials by powder metallurgy. Cemented carbide rolls are available in two types: integral and combined. They have superior performance, stable quality, high product processing accuracy, good wear resistance and high impact resistance. Cemented carbide rolls have good wear resistance, high temperature red hardness, heat fatigue resistance and high strength. According to the differences in the working environment of each stand roll, various grades of cemented carbide roll rings have been developed. Cemented carbide rolls are one of the indispensable devices in the production of rods, wires, threaded steel and seamless steel pipes. For example, one described in the prior art announcement number (CN220216237U) A cemented carbide rolling roller is connected and processed by setting a processing roller on the outside of the connecting inner rod. Then, during the processing, there are many types of parts to be processed. The extrusion plate can be connected on both sides of the processing roller by setting a sleeve ring. Then the sealing plate is connected to provide extrusion stability. The plug-in rod is plugged into the inside of the processing roller, aligned with the internal thread, and then screwed in and fixed by fastening screws. The processing roller can be replaced during use and adjusted according to different processing materials. Then, when the rolling roller is installed on the equipment as a whole, the plug-in plate at the tip can be plugged in. The design of the tip is slightly smaller than the size of the plug-in hole, which can make the plug-in more convenient. Then the internal card slot is connected to limit the position.
