Problems solved by technology

The disadvantage of the grinding wheel is that the grinding wheel is easy to break, causing machine and personnel casualties
The disadvantage of the grinding wheel is that the durability of the grinding wheel is low
The disadvantage of this grinding wheel formula is that it is easy to burn the rail
However, at present, the overall utilization of sulfuric acid slag is less than 50%, and the rest of the unused sulfuric acid slag flows into the environment, causing great environmental pollution.
[0011] There is no literature report on the use of sulfuric acid slag in the manufacture of grinding wheels

Embodiment 1）

[0018] The rail grinding resin emery wheel containing sulfuric acid slag of the present embodiment is made of the following substances by weight percentage:

[0019] The particle size of the abrasive is 60% of 12-mesh zirconium corundum,

[0020] The particle size of the abrasive is 16 mesh high temperature calcined brown corundum 20%,

[0021] Furfural 1% as a binder,

[0022] Phenolic resin powder 11% as binder,

[0023] As a filler, the particle size is 1250 mesh barite 4%,

[0024] As a filler, the particle size is 325 mesh cryolite 3%,

[0025] As a filler, heat conducting agent, and lubricant, the particle size is 1% of sulfuric acid slag of 500 mesh.

[0026] The manufacture method of the rail grinding resin emery wheel containing sulfuric acid slag of the present embodiment is as follows:

Abstract

The invention discloses a resin sand wheel containing sulfuric acid slag for milling a steel rail. The resin sand wheel is prepared from the following substances in weight percentage: 50-70% of corundum, 15-25% of brown fused alumina, 0.5-3% of furfural, 8-14% of phenolic resin powder, 3-6% of barite, 2-10% of kryocide and 0.5-5% of the sulfuric acid slag, wherein the granularity of the corundum is 12-16 meshes; and the brown fused alumina is high-temperature roasted brown fused alumina. According to the invention, the sane wheel is manufactured by the sulfuric acid slag, so that not only can the production cost be reduced, but also the pollution of the sulfuric acid slag to an environment is effectively reduced, thus being of great significance to environmental friendliness.

Description

technical field [0001] The invention relates to a resin grinding wheel, in particular to a rail grinding resin grinding wheel containing sulfuric acid slag. Background technique [0002] The grinding wheel is a circular bonded abrasive with a through hole in the center made of abrasives, bonding agents, pores and fillers. [0003] Grinding wheels are mainly divided into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels and diamond grinding wheels according to the types of binders used. Resin grinding wheels are grinding wheels using resin bonds. Resin and more. [0004] Rail Grinding Resin Grinding Wheel (also known as rail grinding resin grinding wheel) is a special grinding wheel used for grinding rails along the railway line. Large load, high wear resistance, long service life, safety and reliability. Therefore, ordinary resin grinding wheels obviously cannot meet this requirement. [0005] Chinese patent document CN101774159A discloses a heavy-du...
