Problems solved by technology

The modified grinding wheel obtained by this scheme has a better function of repairing the surface defects and out-of-roundness of the wheel, but in this application, a large amount of organic binder is added to improve the bonding force between the components of the grinding wheel. When the grinding wheel During emergency braking, a large amount of heat will be generated to cause the adhesive to decompose. The quality of the grinding wheel cannot be guaranteed, which seriously affects the braking effect and safety performance cannot be guaranteed. This solution still needs further improvement

Abstract

The invention discloses a rounding grinderabrasive block for rail traffic, and belongs to the technical field of braking material preparation. The rounding grinderabrasive block for rail traffic comprises a composite binding agent, rounding particles, an antioxidant, an abrasion-reduction assistant and fibers, the composite binding agent comprises an inorganic binding agent and an organic bindingagent, and the addition ratio of the inorganic binding agent to the composite binding agent is 1 / 10 to 3 / 10. The rounding grinderabrasive block for rail traffic can overcome defects caused by qualitydefects of the grinderabrasive block, the quality defects such as slag and lump falling caused by thermal cracks on the surface of the grinderabrasive block obtained through the method are greatly reduced, the impact strength is improved, and safety and stability are better achieved in the using process.

Description

technical field [0001] The invention belongs to the technical field of brake material preparation, and more specifically relates to a rounding grinder for rail transit. Background technique [0002] Due to its high-efficiency transportation characteristics, urban rail transit has been put into operation or construction in most large and medium-sized cities. However, due to the unique characteristics of the topography and buildings of each major city, the lines of rail transit have their own characteristics. Due to the different lines, the wheel-rail relationship of rail transit vehicles is also different. Some lines have more polygonal wheels, and some lines often have wheel or track scratches, especially polygonalization brings abnormalities to vehicles. Vibration poses a great risk to driving safety. [0003] The grinding wheel is a friction part in the tread cleaner that has the functions of cleaning, thickening, and rounding. In view of the above functions, the grinding...
