Embodiment 1
[0035] This embodiment discloses a preparation formula for rail grinding wheel, which is made of the following components, and its weight fraction ratio is: 70 parts of zirconium corundum, 5 parts of iron sulfide powder, 4 parts of cryolite, 1 part of calcium carbonate, gypsum 1 part of powder and 7 parts of phenolic resin are mixed according to the aforementioned production process, sintered, wound, dried and hardened to shape. In order to make the produced grinding wheel stronger in cutting force, the zirconium corundum with a grain size of 14-16 meshes is selected.
Embodiment 2
[0037] This embodiment discloses a preparation formula of a rail grinding wheel, which is made of the following components, and its weight fraction ratio is: 100 parts of zirconium corundum, 8 parts of iron sulfide powder, 8 parts of cryolite, 3 parts of calcium carbonate, gypsum 4 parts of powder and 10 parts of phenolic resin are mixed according to the above-mentioned production process, sintered, wound, dried and hardened to shape. In order to make the produced grinding wheel stronger in cutting force, the zirconium corundum with a grain size of 14-16 meshes is selected.
Embodiment 3
[0039] As the best embodiment of the present invention, it is made of the following components, and its weight fraction ratio is: 85 parts of zirconium corundum, 6.5 parts of iron sulfide powder, 6 parts of cryolite, 2 parts of calcium carbonate, 2 parts of gypsum powder, phenolic 8.5 parts of resin, mixed, sintered, wound and dried and hardened according to the aforementioned production process. In order to make the produced grinding wheel stronger in cutting force, the zirconium corundum with a grain size of 14-16 meshes is selected.
