Description
Technical field
The invention belongs to bed piece casting technique, more particularly to a kind of utilize the side for making steel tailings casting bed piece
Method.
Background technology
Lathe refers to the machine of manufacture machine, also known as machine-tool or toolroom machine, traditionally abbreviation lathe.It is generally divided into gold
Belong to stock-removing machine, forging machine tool and wood craft machines etc..The method of processing equipment part is many in modern mechanical manufacturing：Except cutting adds
Outside work, also casting, forging, welding, punching press, extruding etc., as long as category required precision is higher and surface roughness requirements are thinner
Part, typically all need to finally it be processed with the method for cutting on lathe.Lathe rises in the construction of national economic modernization
Significant role.Because lathe has strict requirements to features such as the steadiness of bed piece in the course of the work.
At present, the material of most of bed piece is mainly made using cast iron on the market, still, using cast iron
Prepare bed piece and complex process be present, die cost is expensive, and production cycle length, the low precision of product, allowance is big, surface
It is of poor quality, the problems such as damping property is poor, thermal coefficient of expansion is big.In recent years, because China's machining industry is to the quiet dynamic of lathe
It can have higher requirements, the performance of traditional machine tool structure material it was found from published data, can be made from meeting to require
Make excellent and the product with long service life is short of very much in actual applications.
Steel-making tailings is the oxidation that the impurity in steelmaking process metal charge (iron and steel scrap etc.) is oxidized agent oxidation and generated
The general name for the product that thing occurs physical-chemical reaction and formed with slag former and furnace lining again.
Steel-making tailings not only occupies cultivated land, and pollutes environment, while also waste of resource.These solid waste are handled and
Comprehensive utilization of resources, it is one of main task of sustainable development of iron and steel industry.At present, the steel-making tailings utilization rate in China is not
Foot 40%, it is mainly used in pavement construction, and reaches 98% in U.S.'s steel-making tailings utilization rate, is visited in the comprehensive utilization of steel-making tailings
We still have larger gap between developed country.Therefore it is very must to improve slag processing and comprehensive utilization of resources level
Will with it is urgent.I, which takes charge of, thinks, it is rich in many kinds of substance to steel-making tailings, possesses completely as casting after special process is handled
The feasibility of bed piece aggregate, the recovery value of steel-making tailings so can be further improved, I takes charge of proposition and will made steel for this
Tailings is used for the research topic for casting bed piece, and successful.
The content of the invention
The present invention proposes a kind of using the method for making steel tailings casting bed piece, the bed piece cast using this method
There is high stability, tension, resistance to compression, the bed piece that thermal coefficient of expansion is low, machining accuracy is high, it is possible to increase lathe adds
Work precision, reduce machine tooling cost.
Technical solution of the present invention is as follows：
A kind of method for casting bed piece using tailings is made steel, comprises the following steps：
First, the steel-making tailings of recovery is put into crusher to be crushed, then crushed again by disintegrating apparatus, obtaining size is
3-15mm irregular tailing particles are standby；
2nd, it is standby that iron sand powder is made through crushing, ball-milling treatment in the iron sand of recovery；
3rd, take 7-10 parts epoxy resin to add epoxy resin diluent by weight and be mixed into solution, add 2.1-3 by weight
It is standby that obtained mixed solution is mixed evenly in part anhydride curing agent, 1 part of bismuth of addition or antimony；
4th, steel-making tailings 65-75 parts, iron sand powder 5-10 parts, Cab-O-sil 5-10 parts, quartz sand 5-10 parts, quartz are taken by weight
Powder 5-10 parts are added in mixer, are mixed evenly, and then mixed solution made from addition step 3, is again stirring for uniformly,
Be eventually adding 1 part of carbon fiber, 1 part of basalt fibre, then by mixer sealing vacuumize, vacuum be 0.001Mpa with
Under, 5-10 minutes are again stirring for, obtain mixed material；
5th, in said mixture material vacuum pumping to bed piece mould, will be heated to 120-150 DEG C solidify 24 hours, then
The demoulding, bed piece just base is made after the demoulding；
6th, initial bed piece obtained above is machined, you can required bed piece is made.
Further, the carbon fiber and basalt fibre are 35~150mm of length chopped fiber.
Further, the Cab-O-sil is 500 mesh powder.
Further, tailings is made steel in step 1 after broken and crushing, is removed being screened via magnetic plant
Steel essence composition.
The present invention, as primary raw material, is made steel in tailings containing materials such as active mineral silicate using steel-making tailings.I
By the way that steel-making tailings is crushed, crushed, after the technique such as magnetic separation and weak basification so that steel-making tailings has cement
Hydraulic properties (intensity can reach C10~C15), with reference to iron sand powder as bed piece aggregate, enable to bed piece to have
The stability higher than mineral bed piece, abrasion resistance more more preferable than cast iron bed piece, higher stability.
The quartz sand of the present invention plays a part of similar sand with iron sand powder, has blind and enhancing steel-making tailings
Connection degree between grain, the present invention as filler, can be sufficient filling with gap using silica flour and Cab-O-sil, reduction stomata,
Strengthen bond effect.
In the present invention, carbon fiber and basalt fibre primarily serve enhancing tensile resistance, play glue combination effect so that thing
Be coupled the intensity and rigidity of integral enhancing bed piece between material so that cast out the bed piece come have it is higher steady
It is qualitative.
The present invention is using bismuth or antimony expands with cold and contracts with heat and the characteristic such as reducible, for adjusting and resisting the materials such as epoxy resin
Caused deformation coefficient, thermal coefficient of expansion is adjusted, while solve the problems, such as glass thermal expansion poor performance.
The present invention uses curing agent of the anhydride curing agent as epoxy resin, and after being heating and curing, cured product shrinks
Rate is low, heat resistance is high, stability is good, and has very high mechanical strength and electrical insulation properties.
By the specific test result in foregoing description and embodiment, compared to the prior art, the present invention has such as
Lower advantage：
The present invention can be obviously improved machine tool mechanical performance comprehensively using the bed piece of steel-making waste residue casting, and it is stable to improve lathe
Property, reduce thermal coefficient of expansion, improve machine tooling Process Precision and and product yield, reduce processing cost indirectly.Utilize steel-making
Waste residue casting bed piece realizes recycling for resource, and realization is turned waste into wealth, and is reduced environmental pollution, and is bed piece casting material
Significant innovation of material, is significant.
