Description
The present invention is divisional application, former Chinese Patent Application No.: 201310350402.X, the applying date: on 08 13rd, 2013, patent name during application: a kind of environment-friendly water-soluble quenching medium and manufacture method thereof.
Technical field
The invention belongs to quenching medium and manufacture field, specifically, a kind of manufacture method of environment-friendly water-soluble quenching medium is related to, more particularly, relate to one to diameter at 2m and more than 2m, and the axle that material is 40Cr carries out quench adopted quenching medium and manufacture method thereof.
Background technology
Steel performance after quenching depends on steel microtexture after quenching, and microtexture of quenching is decided by the composition of steel, the size of part and quench cooling rate.Improve steel part through hardening effect and have two effective ways: one is that the alloying element content improving raw material makes C curve move to right; Two is improve quench cooling rate.The simple cost of the latter is lower, it is the effective way improving steel part quenching quality, simultaneously, quenching thermal stresses and structural stress size depend on the homogeneity (i.e. surface wettability homogeneity) of speed of cooling and cooling, workpiece quenching process strain cracking is avoided to be the problem must considered during thermal treatment process is formulated, therefore, the homogeneity of controlled cooling model speed and cooling is optimized significant for quenching technology, quenchant should have suitable cooling characteristic, carbon steel and low alloy steel quench cooled is to before 650 DEG C, austenite is also more stable, allow to cool with slower speed, to reduce the thermal stresses that workpiece causes because of internal-external temperature difference, 650 ~ 450 DEG C of scopes, require enough fast speed of cooling, should drop to very low lower than the following speed of cooling of Ms point, to reduce structural stress, prevent excessive distortion and hardening crack, the temperature range of the austenite of different steel grade least stable region is different, therefore desirable cooling curve is different because of the austenite kinetic curve of different steel grade, the quenchant obtaining being applicable to various steel and different size workpiece is wanted to be practically impossible, the cooling characteristic of various quenchant must be understood, to select suitable quenchant and rational quenching method according to the concrete part of different steel grade.The quenching of thick heavy parts is not tractable class quenching during thermal treatment process is produced always, because its volume is large, contain heat high, hardenability and hardening capacity require high, conventional quenching oil and water-soluble quenching liquid cannot realize its speed of cooling needed, thus mechanical property and the microtexture requirement of part cannot be met, generally aqueous sodium hydroxide solution is adopted in modern industry, SODIUMNITRATE-Sodium Nitrite-Alkitrate, water glass (i.e. water glass) aqueous solution etc. quenches, but because the aqueous sodium hydroxide solution of high density has corrodibility, be used alone and workpiece surface can be caused to get rusty, and Sodium Nitrite has toxicity, easily carcinogenic, in-situ production environment and operation operating mode poor, extreme influence environment clean, and water glass (i.e. water glass) aqueous solution is when workpiece quenching cools, because workpiece surface temperature is more than 800 degrees Celsius, the solution rapid vaporization being attached to workpiece surface can be made, this steam or mist have stimulation and corrodibility to respiratory mucosa, chemical pneumonitis can be caused.Liquid or mist have intense stimulus to eye, can cause conjunctiva and keratohelcosis.Skin contact liquid can cause dermatitis or burn.Along with the development of science and technology, science and technology is improving, especially effective diameter is at 2m and more than 2m, and material is the axle of 40Cr, the occasion of present application gets more and more, the cost of this axle is very expensive, but this axle is when quenching, common quenching medium is easy to hardening crack, causes huge waste, for this reason, present needs designs special quenching medium, not only want effectively to meet the quenching requirement that diameter is the axle of 40Cr at 2m and more than 2m, material, also will reduce environmental pollution, high degree improves Working environment.
Summary of the invention
The problem that 1, will solve
For existing quenching medium to diameter at 2m and more than 2m, and the problem of material is the axle of 40Cr when quenching easy hardening crack, the invention provides a kind of manufacture method of environment-friendly water-soluble quenching medium, this quenching medium is by adding rational component and the strict component proportion controlled, speed of cooling for large profile shaft can strictly control, the generation of hardening crack situation can be avoided, the manufacture method of this quenching medium, by controlling order of addition and the temperature of raw material, guarantee that in this quenching medium, the complete disperse of each component is uniformly distributed, make this quenching medium meet quenching requirement.
