Description
Technical field
The present invention relates to abrasive techniques fields, more particularly, to a kind of multiple elements design grinding tool made of industrial waste abrasive material
Preparation method.
Background technique
Grinding tool is fired by abrasive material through extrusion forming, drying and dewatering and high temperature, and abrasive material is divided into silicon carbide by material and grinds
Material and corundum abrasive two major classes, wherein silicon carbide abrasive mainly has black silicon carbide, green silicon carbide and extraordinary silicon carbide abrasive；Corundum
Abrasive material mainly has Brown Alundum, white fused alumina and single alundum abrasive material.Abrasive material has sharp keen and hard characteristic, is softer for being ground
Material surface, be processing the indispensable abrasive material of every kind of sophisticated product.Wherein silicon carbide abrasive product (grinding tool) is in ceramics
Using at most in the industries such as industry, steel, magnetic material, electromagnetism, silicon carbide articles mainly have grinding wheel, bistrique, grinding stone, carbonization
Silicon refractory slab, carbonization silicon pillar, silicon carbide push plate, silicon carbide tower tray, carborundum tube, silicon carbide deacidizing tank, silicon carbide funnel, carbonization
Silicon burner, silicon carbide crossbeam, silicon carbide club etc. a series of main components are the grinding tool products of silicon carbide.Grinding wheel is by its processing
Object difference is divided into the plain wheel made of silicon carbide and corundum and the hard grinding wheel made of diamond, and plain wheel is by viscous
Mixture is divided into vitrified bonded grinding wheel, resin bond wheel and rubber bonded grinding wheel.Vitrified bonded grinding wheel is mainly used for
Inside and outside circle mill, centreless grinding, flat stone mill and tool grinder；Resin bond wheel is mainly used for the cutting, reconditioning and famine of metal material
Mill；Rubber bonded grinding wheel is mainly used for fine granularity fine-grinding and polishing.Plain wheel dosage accounts for 90% of abrasive consumption or so, produces per year
Amount is up to 20 omnipotent tons, and wherein silicon carbide abrasive accounts for 70-80%, and annual resulting waste and old silicon carbide abrasive is up to 50,000 tons.
With the development of society, regenerated resources effective use has become the focus of people's growing interest, it can not only reduce enterprise's production
Cost and China solve resource exhaustion and nervous effective way.Therefore the waste and old abrasive material regeneration of silicon carbide how is made to be
People solve the problems, such as, and report also few, practical application in relation to the waste and old abrasive material regenerative use technology of silicon carbide in the prior art
Less.
Summary of the invention
For the above-mentioned waste and old abrasive material of silicon carbide in the prior art problem encountered in regeneration, the present invention provides
A kind of service performance not only can ensure that silicon carbide abrasive, and waste and old silicon carbide abrasive can be made full use of, it reduces enterprise and is produced into
This, the preparation method of multiple elements design abrasive material made of industrial waste abrasive material to economize on resources.
A kind of preparation method of multiple elements design grinding tool made of waste and old abrasive material of the present invention: the multiple elements design abrasive material
It is made of following raw materials: the thermosetting property tree of the silicon dioxide powder of 40-50wt%, the waste and old carborundum powder of 30-40wt%, 5-10wt%
Rouge, the waste and old schmigel of 5-10wt%, the clay of 3-5wt% and the blast furnace slag of 3-5wt%, and as follows step preparation and
At:
A, the waste and old abrasive material of silicon carbide and the waste and old abrasive material of corundum are first kept the temperature into 1-2 at 900-1000 DEG C after broken, ball milling respectively
The waste and old carborundum powder of different grain size grade specification is made in hour calcination, cooling screening,
It b, will be after silicon dioxide powder, waste and old carborundum powder, waste and old schmigel, clay and blast furnace slag raw material in proportion mixing and ball milling
The mixture of different grain size grade is made in sieving, then phenolic resin mixing system is separately added into the mixture of different grain size grade
At abrasive material,
C, the abrasive material of different grain size grade is added in mold, in the case where pressure is 20-30MPa pressure maintaining 10 minutes, then mould unloading takes out
Abrasive tool blank,
D, abrasive tool blank is kept the temperature at 80-120 DEG C is dried to water content less than 1%,
F, the abrasive tool blank dried described in step d is placed in kiln, after being warming up to 800-900 DEG C with 80-100 DEG C/h
Multiple elements design grinding tool is made in heat preservation 8-10 hours, then furnace cooling.
The different grain size grade by abrasive material in industry requirement bonded abrasive products 17 grades of general granularity (12#~
The execution of 9 most grades (30#~30#) of application in 280#).30# abrasive size is 500-650 μm and (is equivalent to 10-15
Mesh), 150# abrasive size is 80-100 μm (being equivalent to 250 mesh), and number bigger, partial size is smaller.According to the range and grinding used
Object difference carry out grinding tool abrasive grain determination.
The cheap waste residue of one kind that the blast-furnace cinder is discharged from blast furnace when being manUfaCtUre of pig iron, is a kind of meltable mixing
Object, main ingredient are calcium oxide, the silica of 30-40% and the aluminium oxide of 5-10% of 30-50%, and steel slag, which is added, can both reduce life
Cost is produced, and the intensity of abrasive matrix can be improved, while is fragile in the glassy state crystal of molten in steel slag at high operating temperatures
The broken hole for being formed as dispersion is conducive to the cooling and chip removal of grinding so that the porosity of abrasive matrix can be improved and inhale permeability.
The present invention makes full use of resource under the service performance (such as tensile strength, bending strength and hardness) for ensuring abrasive material
Abundant, cheap waste and old silicon carbide and corundum waste material, waste material dosage account for the 50% of original silicon carbide dosage, are carbonized at present
Silicon market price averagely presses 4500 yuan/ton, and 800 yuan/ton of waste and old silicon carbide deducts 500 yuan/ton of valence of waste material processing, per ton to drop
Inexpensive 1000-1500 member (being 50% calculating by waste material additional amount).By the enterprise calculation for producing 10000 tons of grinding tools per year, can reduce into
This is up to 10,000,000 yuan.
Grinding tool of the present invention has mechanical performance: tensile strength 15-20MPa, bending strength 50-60MPa, and Mohs is hard
Degree is 9-9.3, specific gravity 3-3.25 g/cm3, it is able to satisfy the linear velocity requirement of 100m/s.
The present invention keeps former in abrasive material first is that using the processed rear a part of raw material of replacement of waste and old silicon carbide and waste and old corundum
Under the mechanical performance come, abrasive material per ton can reduce nearly 1000 yuan of production cost, achieve preferable economic benefit, while can save
Resource is good for the environment the sustainable development with ecological protection and economy；Second is that the present invention uses low temperature fast firing, shorten than originally
Firing time 10 hours or more, save every 200 yuan of tondal of fuel cost.
