Abstract
The invention discloses a quenching agent for thermal treatment. The quenching agent comprises the following components by mass percent: 15-20% of polyether, 5 to 8% of isopropanolamine, 5 to 10% of polyvinyl alcohol, 3 to 7% of acrylic ester, 6 to 12% of sodium hydroxide, 0.1 to 2% of an additive and 6 to 8% of zinc chloride, and the balance being water. According to the quenching agent for thermal treatment, the formula is reasonable, the pollution is avoided, the quenching effect is good, and a quenched part is relatively high and uniform in hardness.
Description
Technical field
The present invention relates to axial workpiece production and processing technical field, particularly belong to a kind of heat treatment and use
Quenching medium.
Background technology
Quenching oil is a kind of process oil, is used as hardening media.Quenching oil must possess following
Characteristic: good cooling performance, high-flash and burning-point, good thermal oxidation stability, low
Viscosity, water content are low.In addition to above-mentioned characteristic, quenching oil also should nontoxic, tasteless, easily locate
Reason, environmentally safe, and make the light of the surface of the work after quenching.Can divide according to rate of cooling
For: (1) conventional quenching oil；(2) fast quenching oil；(3) super (high) speed quenching oil.Hypervelocity is quenched
Kerosene has quickish rate of cooling, than fast quenching oil faster.This oil is refined paraffin wax
Based lubricating oil adds modulation such as urging cryogen, detersive and antioxidant form.Oil temperature is 800
DEG C time its characteristic temperature be not less than 585 DEG C, be cooled to times of 400 DEG C than quickly by 800 DEG C
Quenching oil is shorter.In use, organic solution after heated can accelerated ageing so that it is cooling spy
Property changes, and as changed not in time, Ways of Heat Treatment Product Quality will be made to decline, the most qualified.
In the market for the quenching medium that the Quenching Treatment of high-abrasive material workpiece is the most unified, wear-resisting
Material quenching processing technology is to think that the important step of its workpiece toughness, research and development high-abrasive material class are quenched
Fire agent is necessary.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of heat treatment quenching medium, joined
Fang Heli, pollution-free, quenching effect is good, and quenching part can reach higher hardness, and hardness is equal
Even.
The technical solution used in the present invention is as follows:
A kind of heat treatment quenching medium, its component and mass fraction thereof are as follows: polyethers 15～20
%, isopropanolamine 5～8%, polyvinyl alcohol: 5～10%, acrylate 3～7%, hydrogen-oxygen
Change sodium 6～12%, additive 0.1～2%, zinc chloride 6～0.2%, excess water.
Described additive includes defoamer 0.05～0.1%, preservative 0.1～0.3%, antirust
Agent 0.1～0.5%, lubricant 0.1～0.5%, antibacterial 0.1～0.5%.
Described defoamer is organosiloxane.
Described preservative is sodium benzoate.
Polyethers 15%, isopropanolamine 5%, polyvinyl alcohol: 5%, acrylate 3%, hydrogen
Sodium oxide 6%, additive 0.1%, zinc chloride 6%.
Described polyethers 20%, isopropanolamine 8%, polyvinyl alcohol: 10%, acrylate
7%, sodium hydroxide 12%, additive 2%, zinc chloride 8.
Described polyethers 18%, isopropanolamine 6%, polyvinyl alcohol: 8%, acrylate 5
%, sodium hydroxide 8%, additive 1%, zinc chloride 7%.
Compared with the prior art, beneficial effects of the present invention is as follows:
Inventive formulation is reasonable, and quenching part can reach higher hardness, and hardness is uniform, available
In direct quenching, remnant forging thermal quenching and sensing flash quenching, especially for quenching of big workpiece
Fire；Sodium hydroxide used in the present invention can interact with the oxide skin on quenching part surface, produces
Raw hydrogen, makes oxide skin rapid deterioration, makes quenching part surface present the silvery white of light；Chlorination
Zinc and sodium hydroxide react generation Strong oxdiative zinc, and high-temperature region stupefied gal speed is faster than water, and low-temperature space is cold
But speed is slower than water, and quenching part deformation is little, the most easy to crack, surface-brightening.
