Abstract
The invention discloses a kind of abrasive wheel for abrasion of steel ball formula, its raw material and weight proportion number be: brown corundum abrasive 18～24 parts, the mixture 6 of a kind of or both arbitrary proportions in white fused alumina abrasive material and single alundum abrasive material～12 parts, silicon carbide abrasive 20 parts, Anhydrite 28～32 parts, clay 15～19 parts, boron glass 2～4 parts.The present invention adds a kind of in white fused alumina abrasive material and single alundum abrasive material or both mixture in brown corundum abrasive, the abrasive wheel for abrasion of steel ball made, primary characteristic is maintained at the aspect such as hardness, density, its grinding efficiency improves more than 20%, after particularly adding single alundum abrasive material, the durability of emery wheel improves about 10%.Moreover, due to the remote little brown corundum abrasive of the impurity in white fused alumina abrasive material and single alundum abrasive material, the percentage of A-class goods of product can be effectively improved.Therefore, the present invention had both improve product quality, and again for using producer to save substantial amounts of manpower, financial resources, comprehensive social benefit is fairly obvious.
Description
Technical field
The present invention relates to a kind of ceramic binder for steel ball grinding wheel formula, be mainly used in the emery wheel making grinding spherical balls.
Background technology
Abrasive wheel for abrasion of steel ball is at the special grinding wheel of below 76.20mm spherical balls for grinding diameter, has the features such as specification is big, fine size, hardness are high, density is big, is widely used in machinery, bearing industry.At present, all abrasive wheel for abrasion of steel ball manufacturers are when formula designs, it is all that the compound abrasive using Brown Alundum and carborundum manufactures abrasive wheel for abrasion of steel ball, because density is big, hardness is high for mill steel sand wheel, simple employing raising typed pressure improves its density certain limit, therefore requires that emery wheel has bigger contraction to improve emery wheel density after burning.And the refractoriness of bonding agent is unsuitable higher, therefore, as used the fine granularity abrasive material of single Brown Alundum, because wherein impurity content is higher, the most whole foaming of emery wheel roasting process；It is suitably added silicon carbide abrasive, the performance of goods can be improved, be conducive to improving intensity and the hardness of goods.But along with the development of national economy, emery wheel uses producer more and more higher to the requirement of abrasive wheel for abrasion of steel ball, not only requires that emery wheel has higher durability, the most also requires that it has higher grinding efficiency.It is known that abrasive wheel for abrasion of steel ball to be made has 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 premise 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
It is an object of the invention to provide a kind of grinding cost performance higher durability high, existing and have again the formula for making abrasive wheel for abrasion of steel ball of higher grinding efficiency.
The technical scheme is that the formula manufacturing ceramic binder for steel ball grinding wheel is the mixture of corundum abrasive using unlike material, add silicon carbide abrasive, bonding agent uses Anhydrite-clay-boron glass system, it thes improvement is that in described formula, each component and weight proportion number are: brown corundum abrasive 18～24 parts, the mixture 6 of a kind of or both arbitrary proportions in white fused alumina abrasive material and single alundum abrasive material～12 parts, silicon carbide abrasive 20 parts, Anhydrite 28～32 parts, clay 15～19 parts, boron glass 2～4 parts.
Further scheme is: in described formula, each component and weight proportion number are: brown corundum abrasive 21 parts, 9 parts of 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, Anhydrite 30 parts, clay 17 parts, boron glass 3 parts；The granularity of described white fused alumina abrasive material and single alundum abrasive material is F180～F240.
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 mixture in brown corundum abrasive.Relative to brown corundum abrasive, white fused alumina is with fine aluminum oxidation powder as raw material, refine crystallization through electric smelting to form, purity is high, self-sharpening is good, acid-alkali-corrosive-resisting, high temperature resistant, hot performance is stable, and hardness is slightly higher, purity is high, self-sharpening is good, grinding capacity is strong, caloric value is little, efficiency is high, acid-alkali-corrosive-resisting, high temperature heat-resistant good stability；Single alundum is with Alumina, anthracite, iron filings and pyrite as raw material, congruent melting in electric arc furnace, in canescence, its grain shape mostly is equivalance shape, in crystal free from foreign meter, having multangular cutting edge, under same grinding force effect, the moment formed is less than other abrasive material, therefore it is the most easy to break broken, mechanical strength is higher, and individual particle comprcssive 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 abrasive wheel for abrasion of steel ball that the formula of application technical solution of the present invention makes, primary characteristic is maintained at the aspect such as hardness, density, its grinding efficiency improves more than 20% simultaneously, after particularly adding single alundum abrasive material, the durability of emery wheel improves about 10%.Moreover, due to the remote little brown corundum abrasive of the impurity in white fused alumina abrasive material and single alundum abrasive material, the percentage of A-class goods of product can be effectively improved, reduce the waste product such as crackle, internal injury.In sum, the present invention had both improve product quality, improved economic benefit and the market competitiveness of emery wheel making enterprise, and again for using producer to save substantial amounts of manpower, financial resources, comprehensive social benefit is fairly obvious.
Detailed description of the invention:
Formulation grinding wheel formula is as follows:
Formula according to above-described embodiment 1, embodiment 2, the embodiment 3 various material of precise respectively, by loading discharging after ball milling in ball mill after mixing, sieving, makes emery wheel according to a conventional method.By the emery wheel of embodiment 1 making after one, Hefei steel ball factory is on probation, the discharging time of every dribbling was reduced to 7.5～8 hours by original 10 hours, and grinding efficiency improves 20～25%.By the emery wheel of embodiment 2 making after one, Changzhou steel ball factory is on probation, every emery wheel, by originally grinding 36 dribblings, rises to mill 40～41 dribblings, and durability improves 11.11～13.88%.By the emery wheel of embodiment 3 making after one, Zhejiang steel ball factory is on probation, the discharging time of every dribbling was reduced to 8～8.5 hours by original 10 hours, and every emery wheel, by originally grinding 36 dribblings, rises to mill 39～40 dribblings, grinding efficiency improves 15～20%, and durability improves 8.33～11.11%.
