Abstract
The invention discloses a formula of abrasives for a grinding wheel. The abrasives comprise the following raw materials in parts by weight: 18-24 parts of a brown corundum abrasive, 6-12 parts of one of or a mixture in any proportion of a white corundum abrasive and a monocrystalline corundum abrasive, 20 parts of a silicon carbide abrasive, 28-32 parts of feldspar, 15-19 parts of clay, and 2-4 parts of borax glass. According to the formula disclosed by the invention, one of or a mixture of the white corundum abrasive and the monocrystalline corundum abrasive is added in the brown corundum abrasive, so that the grinding wheel prepared according to the formula maintains the original hardness, the density and the like, and the grinding efficiency and the durability of the grinding wheel are improved. Therefore, through the adoption of the formula disclosed by the invention, the quality of the abrasives is improved, and besides, the cost is reduced for manufacturers, so that the comprehensive benefits are obvious.
Description
Technical field
The invention belongs to emery wheel making field, be specifically related to a kind of abrasive material formula of emery wheel.
Background technology
Emery wheel is for grinding tool topmost in Grinding Process, is widely used in all kinds of mechanical processing industry.Because abrasive material, bonding agent and manufacturing process are different, the characteristic difference of emery wheel is very large, therefore to the crudy of grinding, productivity ratio and economy important.At present, overwhelming majority emery wheel manufacturer is when abrasive material formula Design, all adopt the compound abrasive of Brown Alundum and carborundum to manufacture emery wheel, because emery wheel density is large, hardness is high, simple employing raising typed pressure improves its density certain limit, therefore requires that emery wheel has larger contraction to improve emery wheel density after burning.And the refractoriness of bonding agent is unsuitable higher, therefore, as adopted the fine granularity abrasive material of single Brown Alundum, because wherein impurity content is higher, the very easily whole foaming of emery wheel roasting process; Suitably add silicon carbide abrasive, the performance of goods can be improved, be conducive to the intensity and the hardness that improve goods.But along with the development of national economy, emery wheel uses the requirement of producer to emery wheel more and more higher, not only requires that emery wheel has higher durability, also requires that it has higher grinding efficiency simultaneously.As everyone knows, emery wheel be made to have higher durability, then the hardness of emery wheel is higher, and at this moment its grinding efficiency declines; Otherwise to improve grinding efficiency, then must reduce the hardness of emery wheel, durability declines.Therefore, under the hardness prerequisite not reducing abrasive wheel for abrasion of steel ball, improve its grinding efficiency, become a difficult problem of emery wheel manufacturing.
Summary of the invention
Object of the present invention is just to provide the abrasive material formula for making emery wheel that high, the existing higher durability of a kind of grinding cost performance has again higher grinding efficiency.
Technical scheme of the present invention is: the abrasive material formula making emery wheel is the mixture of the corundum abrasive adopting unlike material, add silicon carbide abrasive, bonding agent adopts feldspar-clay-boron glass system, its improvements are that in described formula, each component and weight proportion number are: brown corundum abrasive 18 ~ 24 parts, 6 ~ 12 parts, the mixture of a kind of or both arbitrary proportions in white fused alumina abrasive material and single alundum abrasive material, silicon carbide abrasive 20 parts, feldspar 28 ~ 32 parts, clay 15 ~ 19 parts, boron glass 2 ~ 4 parts.
Advantage of the present invention is: technical solution of the present invention breaches the formula of traditional abrasive wheel for abrasion of steel ball, adds a kind of in white fused alumina abrasive material and single alundum abrasive material or both mixtures in brown corundum abrasive.Relative to brown corundum abrasive, white fused alumina for raw material with fine aluminum oxidation powder, refines crystallization through electric smelting and forms, and has the advantages such as purity is high, self-sharpening good, acid-alkali-corrosive-resisting, high temperature resistant, hot performance is stable.Single alundum is for raw material with alumina, anthracite, iron filings and pyrite, congruent melting in electric arc furnaces, in canescence, its grain shape mostly is equivalance shape, free from foreign meter in crystal, have multangular cutting edge, under same grinding force effect, the moment formed is less than other abrasive material, therefore it is not easy to break broken, mechanical strength is higher, and individual particle compression strength is 22 ~ 38kg, and Brown Alundum is only 10 ~ 20kg.Single alundum is owing to having higher hardness and toughness, and cutting power is stronger.Show according to test, compared with conventional formulation, the emery wheel of the formula making of application technical solution of the present invention, primary characteristic is maintained in hardness, density etc., its grinding efficiency improves simultaneously, and after particularly adding single alundum abrasive material, the durability of emery wheel also improves.Moreover, due to the little brown corundum abrasive far away of the impurity in white fused alumina abrasive material and single alundum abrasive material, effectively can improve the percentage of A-class goods of product, reduce the waste product such as crackle, internal injury.In sum, the present invention both improve product quality, improved economic benefit and the market competitiveness of emery wheel making enterprise, and again for using producer to save cost, comprehensive benefit is fairly obvious.
Preferably, in described formula, each component and weight proportion number are: brown corundum abrasive 21 parts, 9 parts, the mixture of a kind of or both arbitrary proportions in white fused alumina abrasive material and single alundum abrasive material, silicon carbide abrasive 20 parts, feldspar 30 parts, clay 17 parts, boron glass 3 parts.Under such ratio, the various aspects of performance such as obtained wheel strength and hardness are in best.
Further, the abrasive material formula of described emery wheel, the granularity of its white fused alumina abrasive material and single alundum abrasive material is F180 ~ F240, when white fused alumina and single alundum granularity reach F180 ~ F240, could meet the making requirement of wheel strength.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Formulation grinding wheel formula is as follows:
According to the formula various material of precise respectively of above-described embodiment 1, embodiment 2, embodiment 3, by loading discharging after ball milling in ball mill after mixing, sieving, make emery wheel according to a conventional method.By the emery wheel that embodiment 1 makes, the discharging time of every dribbling reduces to 7.5 ~ 8 hours by original 10, and grinding efficiency improves 20 ~ 25%.By the emery wheel that embodiment 2 makes, every sheet emery wheel, by originally grinding 36 dribblings, rises to mill 40 ~ 41 dribbling, and durability improves 11.11 ~ 13.88%.By the emery wheel that embodiment 3 makes, the discharging time of every dribbling reduced to 8 ~ 8.5 hours by original 10 hours, and every sheet emery wheel was by originally grinding 36 dribblings, and rise to mill 39 ~ 40 dribbling, grinding efficiency improves 5 ~ 20%, and durability improves 8.33 ~ 11.11%.
