Abstract
The invention relates to a quenching liquid with an anti-corrosion effect, which comprises the following components in percentage by mass: 4-8% of antioxidant, 1-3% of caprylic acid, 1-3% of anticorrosive agent, 2-6% of scale inhibitor, 1-4% of defoaming agent, 0-2% of antioxidant and the balance of water. The invention has the advantages of safety, environmental protection, corrosion inhibition and long service life; the quenching liquid provided by the invention overcomes the problem that the traditional quenching liquid is fast in cooling and easy to crack, and effectively improves the quality of steel products.
Description
Technical Field
The invention relates to the technical field of quenching liquid, in particular to quenching liquid with an anti-corrosion effect.
Background
Quenching is a heat treatment process of metals in which a metal workpiece is heated to a suitable temperature and held for a period of time, and then immersed in a quenching medium for rapid cooling. The purpose of quenching is to improve the strength and hardness of the metal workpiece, increase the wear resistance, and obtain the workpiece with high strength and hardness, certain elasticity and toughness and excellent comprehensive mechanical properties through tempering treatment.
The quenching medium is usually saline water, mineral oil, air, etc. The quenching process is mainly used for steel parts, and when the common steel is heated to a temperature above a critical temperature, the original structure at room temperature is completely or mostly transformed into austenite, and then the steel is immersed into oil or water for rapid cooling, so that the austenite is transformed into martensite. The martensite hardness is highest compared to other structures in steel. The existing quenching liquid oil product has slow cooling speed, poor quenching effect and inflammability; although the water product has high speed, the workpiece is easy to crack.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the water-soluble quenching liquid with high speed and good effect.
The technical scheme adopted by the invention is as follows: a quenching liquid with an anticorrosion effect comprises the following components in percentage by mass:
4 to 8 percent of antioxidant
1 to 3 percent of caprylic acid
1 to 3 percent of anticorrosive agent
2 to 6 percent of scale inhibitor
1 to 4 percent of defoaming agent
0 to 2 percent of antioxidant
The balance being water.
As a further improvement of the present invention, the water is ion-exchanged water.
The invention has the following beneficial effects: the invention has the advantages of safety, environmental protection, corrosion inhibition and long service life;
the quenching liquid provided by the invention overcomes the problem that the traditional quenching liquid is fast in cooling and easy to crack, and effectively improves the quality of steel products.

the antioxidant accounts for 7%
Octanoic acid 3%
Anticorrosive agent 1%
Scale inhibitor 5%
2 percent of defoaming agent
1 percent of antioxidant
The balance being ion exchange water.
The invention has the advantages of safety, environmental protection, corrosion inhibition and long service life; the quenching liquid provided by the invention overcomes the problem that the traditional quenching liquid is fast in cooling and easy to crack, and effectively improves the quality of steel products.
It should be understood by those skilled in the art that the protection scheme of the present invention is not limited to the above-mentioned embodiments, and various permutations, combinations and modifications can be made on the above-mentioned embodiments without departing from the spirit of the present invention, and the modifications are within the scope of the present invention.
