Abstract
The invention relates to the field of abrasive wheel manufacture and discloses a steel rail cutting abrasive wheel. The abrasive wheel is made by mixing a major material and an auxiliary material according to mass percent, wherein the major material is composed of, by weight, 55-65% of brown fused alumina and 35-45% of fused zirconia alumina, and the total mass is 100%; the auxiliary material is composed of, by weight, resin sand accounting for 17-20% of the major material, cryolite accounting for 1-3% of the major material and iron sulfide accounting for 0.5-1% of the major material. Strength, self-sharpening performance and grinding performance of the abrasive wheel can be effectively improved, thereby cutting stability and cutting efficiency of the abrasive wheel are improved correspondingly.
Description
[technical field]
The present invention relates to emery wheel and manufacture field, especially relate to a kind of for cutting the emery wheel of rail.
[background technology]
Known, rail cutting is substantially all operation in the wild, and not only operating environment is severe for it, and also comparatively harsh to the requirement of cutting equipment and emery wheel, at present, because domestic emery wheel manufacturing enterprise all has deficiency at aspects such as technology and equipments, therefore, domestic production for cutting the emery wheel of rail, not only intensity is lower, easily broken in implementation process, and its self-sharpening can be also all relative poor with grinding performance, in addition, in cutting process, existing emery wheel may cause rail to be burnt or crackle equivalent damage because oxidation appears in excess Temperature in addition, this not only can have influence on normal rail cutting, and the rail profile quality cutting out is lower, therefore, how to improve the quality of emery wheel, increase its intensity, ensure that its stability and cutting efficiency in cutting process just becomes an important subject in emery wheel manufacture.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of rail abrasive cut-off wheel, described emery wheel can effectively improve its intensity, self-sharpening energy and grinding performance, thus corresponding stability and the cutting efficiency that has improved its cutting.
For achieving the above object, the present invention adopts following technical scheme:
A kind of rail abrasive cut-off wheel, described emery wheel is mixed by mass percentage by major ingredient and auxiliary material; Described major ingredient is comprised of 55～65% brown corundum and 35～45% fused alumina zirconias, and gross mass is 100%; Described auxiliary material is the resin-oatmeal that accounts for major ingredient 17～20%, account for the ice crystal of major ingredient 1～3% and account for the iron sulfide composition of major ingredient 0.5～1%.
Described rail abrasive cut-off wheel, described major ingredient is comprised of 60% brown corundum and 40% fused alumina zirconia.
Described rail abrasive cut-off wheel, described auxiliary material by accounting for the resin-oatmeal of major ingredient 18%, the iron sulfide that accounts for the ice crystal of major ingredient 3% and account for major ingredient 1% forms.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Rail abrasive cut-off wheel of the present invention not only intensity is good, be difficult for broken, and its self-sharpening can and grinding performance better; Described emery wheel can support the use with import high speed rail cutter, and not only cutting efficiency is high for it, consumes littlely, do not damage rail, and the quality of its rail section can meet Ministry of Railways's standard completely.
[specific embodiment]
By the following examples, can explain in more detail the present invention, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Described rail abrasive cut-off wheel is mixed by mass percentage by major ingredient and auxiliary material; Described major ingredient is comprised of 55～65% brown corundum and 35～45% fused alumina zirconias, and its gross mass is 100%; Described auxiliary material is the resin-oatmeal that accounts for major ingredient gross mass 17～20%, account for the ice crystal of major ingredient gross mass 1～3% and account for the iron sulfide composition of major ingredient gross mass 0.5～1%, and auxiliary material is formulated on the quality base of major ingredient; As required, can adopt the major ingredient of being made by the fused alumina zirconia of 60% brown corundum and 40%, and by account for major ingredient gross mass 18% resin-oatmeal, account for the ice crystal of major ingredient gross mass 3% and account for the auxiliary material that the iron sulfide of major ingredient gross mass 1% makes and form.
While implementing described rail abrasive cut-off wheel, because the brown corundum hardness and the toughness that contain in described emery wheel are larger, it is applicable to middle high-tensile metal material, as the grinding of carbon steel, steel alloy, malleable cast steel and hard bronze; Not only hardness is high, toughness is large for fused alumina zirconia, and its granule strength is large, sharpness is high, is applicable to the grinding of stainless steel, adjustment steel or high-vanadium steel; Iron sulfide can play the effect of good filler; Resin-oatmeal is for improving self-sharpening, the cementability of emery wheel, and cutting efficiency; Ice crystal not only can improve bonding force, play strengthening action, but also can impel Grain Falling Off, prevent that emery wheel from stopping up, can also effectively reduce grinding skin temperature and degree of oxidation, reach minimizing burn surface area simultaneously, improve the object of cutting speed and prolongation wheel life, therefore, described emery wheel can effectively improve its intensity, self-sharpening energy and grinding performance, thus corresponding stability and the cutting efficiency that has improved its cutting.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
