Abstract
The invention discloses a medium for carrying out medium-frequency hardening on the surface of a medium-carbon alloy steel workpiece. The medium comprises a stock solution prepared from the following components in percentage by weight: 9%-10% of barium petroleum sulfonate, 14%-15% of sulfonated oil DAH, 9%-10% of triethanolamine oleic soap, 14%-15% of castor oil sodium soap, 14%-15% of benzotriazole, 29%-30% of No.5, No.6 or No.4 high-speed engine oil and 5%-11% of oleic acid. The nonflammable medium-carbon alloy steel hardening medium disclosed by the invention can be used for spraying medium-frequency hardening, has good cooling effect, can achieve the hardening qualification up to 99% and can be used for designing the hardening of various medium-carbon alloy steels according to the cooling curves of steel products.
Description
Technical field
The present invention relates to a kind of hardening media, more particularly, relate to the medium of medium carbon alloy steel mid frequency induction hardening.
Background technology
Along with China's heavy industry also obtains development, the service life of various machine components is all improving gradually, and production cost is all declining gradually.In this case, the workpiece of production existing good precision will have service life of overlength again.
For the workpiece of medium carbon alloy steel, want the service life of improving workpiece, the most important effect wanted just is served to the heat treatment of medium carbon alloy steel, but medium carbon alloy steel surface mid frequency induction hardening is but a difficult problem always.Because medium carbon alloy steel has quenching degree feature good and easy to crack, hardening media is in the past quenching oil, and oil is combustibles, can not be used in the surface spraying quenching of intermediate frequency.
Summary of the invention
The present invention aims to provide a kind of incombustible hardening media, can reach more than 99% to the intermediate frequency surface hardening qualification rate of medium carbon alloy steel workpiece.
In order to achieve the above object, a kind of medium for medium carbon alloy steel workpiece surface mid frequency induction hardening of the present invention, comprises the stoste that following composition is formulated by weight ratio by weight ratio:
Barium mahogany sulfonate: 9-10%
Sulfonated oil DAH:14-15%
Trihydroxy ethylamine oleate soap: 9-10% (content is more, and rust-proof effect is better)
Castor oil soda soap 14-15%
Benzotriazole 14-15% (content is more, and antiseptic effect is better)
No. 5, No. 6 or No. 4 high-speed engine oil: 29-30%
Oleic acid: 5-11%.
Wherein, No. 6 high-speed engine oils are preferably used when serviceability temperature is at 25 DEG C-40 DEG C; When serviceability temperature is preferably use No. 4 high-speed engine oils configurations at 5-15 DEG C.Under other able state, preferably use No. 5 high-speed engine oils.
During use, it is complete compatible rear as hardening media that above-mentioned stoste and distilled water press 8%-10% part by weight.
Advantage of the present invention is as follows:
1, cost-saving, every 10Kg stoste medium, the configurable 100Kg aqueous solution, for quenching, cost is far below the quenching oil of prior art.
2, do not burn, without safety problem
3, easily recovery is reusable.
4, without any corrosiveness, can take up in any container
5, can spray quench be adopted, compensate for the shortcoming that quenching oil can not spray.
To sum up, the present invention is a kind of nonflammable class medium carbon alloy steel hardening media, can be used for spraying mid frequency induction hardening, its good cooling results, and quenching qualifiedly reaches 99%, in addition, can design the quenching of various medium carbon alloy steel according to steel cooling curve.
Accompanying drawing explanation
Fig. 1 is hardening media cooling performance resolution chart.
Detailed description of the invention
One, the concrete composition of hardening media of the present invention is as follows:
Barium mahogany sulfonate
Sulfonated oil DAH
Trihydroxy ethylamine oleate soap (10:7)
Castor oil soda soap
Benzotriazole
No. 5 high-speed engine oils
Oleic acid
Two, the preparation of hardening media of the present invention
Various article are mixed with hardening media stoste by a certain percentage above.
Three, hardening media using method of the present invention:
Distilled water is contained in required container.
Hardening media stoste and distilled water are joined in container in 1:10 ratio.
Stir, treating after 10 minutes that two media is completely compatible can use.
The mode of spray quench can be selected during use.
Four, the cooling performance of hardening media of the present invention
Composition graphs 1 illustrates hardening media cooling performance of the present invention test (applied code: JB/T7951-2004, SH/0220-1992).Wherein, performance is as shown in the table.
| Maximum cooling velocity | Maximum cooling rate temperature | To 300 DEG C of cooling rates | Medium temperature |
| 82.8℃/S | 488.7℃ | 36.4℃/S | 40℃ |
Annotation: maximum cooling rate: in quenching process, maximum cooling velocity is the ability of reduction temperature per second.
Maximum cooling rate temperature: workpiece temperature during maximum cooling rate
To 300 DEG C of cooling rates: the time required when workpiece probe drops to 300 DEG C as shown in the figure:
15.1S, learns that 300 DEG C of cooling rates are 36.4 DEG C/S.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
