Abstract
The invention discloses a kind of novel quenching mediums, it is made of in parts by weight following raw material: 5-15 parts of polyethers, 1-5 parts of sodium bicarbonate, 5-10 parts of glycerine, 2-5 parts of ammonium borate, 0.1-0.5 parts of gelatinized starch, 3-5 parts of polyvinyl alcohol, 0.5-1 parts of sodium molybdate, 1-2 parts of sebacic acid, 0.02-0.2 parts of fluorine silicon defoaming agent, 2,4,6- 0.1-0.5 parts of tert-butyl hydroquinone, surplus are deionized water；The present invention has the advantages that safe and environment-friendly, inhibition, long service life；Quenching liquid of the invention overcomes the cooling fast but easy to crack problem of traditional quenching liquid, effectively raises the quality of steel product.
Description
Technical field
The present invention relates to metal quenching technology fields, and in particular to a kind of novel quenching medium.
Background technique
Oiliness quenching medium is easy pollution environment in quenching process, generates a large amount of smog, causes to the health of operator
It influences, in addition, the flash-point of mineral oil is low, is easy to happen fire, use is dangerous；Water-soluble quenching agent is that organic polymer is molten
Agent is soluble in water, meets the cooling performance of quenching medium by adjusting the concentration and temperature of solution.Water-soluble quenching agent is entire
Have high cooling velocity in cooling procedure, crystal grain refinement, crystal form rule can be promoted in the High-temperature cooling stage, be conducive to improve
The service performance of work, but in cold stage, there are excessively high cooling velocities to be easy to cause workpiece cracking, quenching distortion, appearance
The problem of soft spots.
Summary of the invention
To solve the above problems, the present invention provides a kind of novel quenching medium, asked with solve to occur in above-mentioned background technique
Topic.
A kind of novel quenching medium, is made of following raw material in parts by weight: 5-15 parts of polyethers, 1-5 parts of sodium bicarbonate, the third three
5-10 parts of alcohol, 2-5 parts of ammonium borate, 0.1-0.5 parts of gelatinized starch, 3-5 parts of polyvinyl alcohol, 0.5-1 parts of sodium molybdate, sebacic acid 1-2
Part, 0.02-0.2 parts of fluorine silicon defoaming agent, 0.1-0.5 parts of 2,4,6- tert-butyl hydroquinone, surplus be deionized water.
As present invention further optimization, be made of in parts by weight following raw material: 12 parts of polyethers, 3 parts of sodium bicarbonate,
6.5 parts of glycerine, 3.6 parts of ammonium borate, 0.33 part of gelatinized starch, 4.2 parts of polyvinyl alcohol, 0.85 part of sodium molybdate, sebacic acid 1.65
Part, 0.12 part of fluorine silicon defoaming agent, 0.30 part of 2,4,6- tert-butyl hydroquinone, surplus be deionized water.
As present invention further optimization, the molecular weight of the polyethers is 50000-60000.
Beneficial effects of the present invention: the present invention has the advantages that safe and environment-friendly, inhibition, long service life；Of the invention quenches
Fiery liquid overcomes the cooling fast but easy to crack problem of traditional quenching liquid, effectively raises the quality of steel product.
Specific embodiment
Below in conjunction with specific preferred embodiment, the invention will be further described, but not thereby limiting the invention
Protection scope.
A kind of novel quenching medium, is made of following raw material in parts by weight: 12 parts of polyethers, 3 parts of sodium bicarbonate, glycerine
6.5 parts, 3.6 parts of ammonium borate, 0.33 part of gelatinized starch, 4.2 parts of polyvinyl alcohol, 0.85 part of sodium molybdate, 1.65 parts of sebacic acid, fluorine silicon
0.12 part of defoaming agent, 0.30 part of 2,4,6- tert-butyl hydroquinone, surplus be deionized water.
Preferably, the molecular weight of polyethers is 55000.
Although the present invention has been indicated and described referring to specific preferred embodiment, shall not be construed as to invention itself
Limitation, without prejudice to the spirit and scope of the invention as defined in the appended claims, can to it on device form,
Various combination variations are made in material, in details.
