Problems solved by technology

In use, the organic solution will accelerate aging after being heated, and its cooling characteristics will change. If it is not replaced in time, the quality of the heat-treated product will be reduced, or even unqualified.
At present, there is no uniform quenching ag

Example Embodiment

[0014] Example 1, a quenching agent for wear-resistant shaft parts, its components and mass fractions are as follows: polyoxyethylene ether 15%, triisopropanolamine 5%, polyvinyl alcohol: 5%, acrylic ester 3 %, sodium hydroxide 6%, additives 0.1%, ammonium borate 0.05%, balance water; the additives include defoamer 0.05-0.1%, preservative 0.1-0.3%, rust inhibitor 0.1-0.5%, lubricant 0.1-0.5%, bactericide 0.1-0.5%; the defoaming agent is organosiloxane; the preservative is sodium benzoate.

Example Embodiment

[0015] Embodiment 2, a quenching agent for wear-resistant shaft parts, its components and their mass fractions are as follows: polyoxyethylene ether 20%, triisopropanolamine 8%, polyvinyl alcohol: 10%, acrylate 7 %, sodium hydroxide 12%, additives 2%, ammonium borate 0.2%, balance water; the additives include defoamer 0.05-0.1%, preservative 0.1-0.3%, rust inhibitor 0.1-0.5%, lubricant 0.1-0.5%, bactericide 0.1-0.5%; the defoaming agent is organosiloxane; the preservative is sodium benzoate.

Example Embodiment

[0016] Embodiment 3, a quenching agent for wear-resistant shaft parts, its components and their mass fractions are as follows: polyoxyethylene ether 18%, triisopropanolamine 6%, polyvinyl alcohol: 8%, acrylate 5 %, sodium hydroxide 8%, additives 1%, ammonium borate 0.1%, balance water; the additives include defoamer 0.05-0.1%, preservative 0.1-0.3%, rust inhibitor 0.1-0.5%, lubricant 0.1-0.5%, bactericide 0.1-0.5%; the defoaming agent is organosiloxane; the preservative is sodium benzoate.

[0017] The formula of the invention is reasonable, and the quenched parts can reach high hardness and uniform hardness. It can be used for direct quenching, forging waste heat quenching and induction jet quenching, especially for the quenching of large workpieces; the sodium hydroxide used in the present invention can quench the surface of the parts The oxide scale interacts with each other to generate hydrogen, which quickly peels off the oxide scale, making the surface of the quenched part ...

Abstract

The invention discloses a quenching agent for a wear-resistant shaft type part. The quenching agent comprises the following components in percentage by mass: 15% to 20% of polyoxyethylene ether, 5% to 8% of triisopropanolamine, 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, 0.05% to 0.2% of ammonium borate and the balance water. The quenching agent disclosed by the invention is reasonable in prescription, free of pollution and good in quenching effect; a quenched part can have relatively-high hardness and is uniform in hardness.

Description

technical field [0001] The invention relates to the technical field of production and processing of shaft parts, in particular to a quenching agent for wear-resistant shaft parts. Background technique [0002] Quenching oil is a process oil used as a quenching medium. Quenching oil must have the following characteristics: good cooling performance, high flash point and ignition point, good thermal oxidation stability, low viscosity, and low moisture content. In addition to the above characteristics, the quenching oil should also be non-toxic, odorless, easy to handle, non-polluting to the environment, and make the surface of the quenched workpiece bright. According to the cooling rate, it can be divided into: (1) ordinary quenching oil; (2) rapid quenching oil; (3) super (high) speed quenching oil. Overspeed quenching oil has a fairly fast cooling rate, faster than rapid quenching oil. The oil is prepared by adding refrigerant, detergent and antioxidant to refined paraffin...
