Abstract
The invention discloses a kind of C6H12O6Aqueous solution quenching medium, the hardening media use C6H12O6It is main component for aqueous solution, by adding micro other compositions, is configured to a kind of novel organic hardening media；The hardening media enables to steel component parts to have cooling velocity more faster than oils hardening media in high temperature perlitic transformation area, avoids pearlite type structural transformation, has the cooling velocity slower than tap water in low-temperature martensite limited proportionality.The characteristics of novel hardening media, between water and quenching oil, combines the cooling characteristics of the two；Not only quenching mechanical performance needed for having ensure that steel part, but also the phenomenon that reduce steel component parts strain cracking, and do not smolder in entire quenching process, phenomenon on fire, and asepsis environment-protecting, the cost of preparation are also more cheap.
Description
Technical field
The invention belongs to the technical fields of the design and preparation of heat-treatment quenching cooling medium, and in particular to a kind of new type water
The simple organic compound quenching medium of base.
Background technique
Hardening media is that the cooling medium for obtaining martensitic structure is quenched for metal material, ideal quenching medium
It is required that the cooling velocity in the perlitic transformation region of steel is fast, and the cooling velocity in martensite transfor mation is slow.It quenches at present
Common problem existing for fiery medium is that tap water is too fast in cold stage (martensite transfor mation stage) cooling velocity, is easy to cause
Part hardening crack, quenching oil high temperature (pearlite station conversion stage) cooling velocity is slower, and part is easy to appear quenching soft spot.For upper
Engineering problem is stated, the novel hardening media of a batch is developed in succession both at home and abroad, such as watersoluble organic polymer solution, including ethers
Solution, alcohols hardening media, PAG are exactly a kind of widely used organic polymer species hardening media at present, water based polymerization
Object hardening media overcomes the shortcomings that water and oil hardening medium to a certain extent, but that there is also products simultaneously is easy to aging, maintenance
Work many and diverse disadvantage.C6H12O6It is a kind of simple organic of non-toxic, environmental friendly, this organic compound is simple and easy to get, price
It is cheap.Experimental study shows that it embodies good cooling characteristics in quenching cooling procedure, and entire operating environment can
Maintain to obtain very cleaning, environmental protection；Based on the above background, the present invention proposes one kind with C6H12O6Aqueous solution it is as main component it is low at
This, water base organic compound hardening media easy to maintain, which is totally different from existing is with macromolecule polyalcohol
The aqueous-based polymers hardening media of main component, but to simplify organic conjunction object as main component, it makes full use of simple organic
The small characteristic of compound cold stage thermal coefficient, have the characteristics that low cost, it is easy to maintain, thus be expected substitute import, reduce
The production cost of machine industry.
Summary of the invention
The present invention uses C6H12O6Aqueous solution is main component, by micro addition other compositions, is configured to one kind
Simple organic hardening media, the cooling characteristics of the hardening media are that have between oil between water；In high temperature perlitic transformation area, this is quenched
Fiery medium enables to steel component parts to have cooling velocity more faster than quenching oil；In low-temperature martensite limited proportionality, the quenching
Medium enables to steel part to have the cooling velocity slower than water.In entire quenching process, supercooling Ovshinsky can be greatly reduced
Body is changed into pearlite, and can reduce the strain cracking of steel component parts, and cheap asepsis environment-protecting.
The present invention is achieved by the following technical solutions:
According to certain percent by volume by C6H12O6(analysis is pure) and water (deionized water) are configured to C6H12O6Aqueous solution,
Antirust agent, age resister, defoaming agent and cooling rate regulator are added, is uniformly mixed by mechanical stirring and C is made6H12O6It is water-soluble
Property hardening media, and stand 24 hours.
The formula of the hardening media are as follows:
C6H12O6(analysis is pure): 3-5% (percent by volume)
Water (deionized water): 95%-97% (percent by volume)
Additive (weight percent): 0.4% antirust agent；0.1% age resister；0.1% defoaming agent；
0.3% cooling rate regulator
Above-mentioned antirust agent is sodium phosphate；Age resister is salicylic acid；Defoaming agent is that (average molecular weight is polyethylene glycol
600)；Cooling rate regulator is polyvinylpyrrolidone (average molecular weight 58000).
Usefulness of the present invention are as follows:
Hardening media of the invention has excellent quenching cooling characteristics；It quenches in cooling procedure, turns in high temperature pearlite
Become area, which enables to the cooling velocity of steel part higher than the cooling velocity of oils hardening media, so as to avoid pearl
Body of light type structural transformation；In low-temperature martensite limited proportionality, which enables to the cooling velocity of steel component parts to be slower than
The cooling velocity of tap water has the cooling characteristics close to ideal quench medium.It is very environmentally friendly in entire quenching process, do not occur
On fire, the phenomenon that smokeing clogging, and the raw material sources in formula are easy to get extensively, and cheap.
