Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an oil-like water-based quenching agent that replaces quenching oil, has no inverse solubility, no toxicity, no smoke, no combustion, no fire hazard, no pollution, no Corrosion, no aging, long service life and other characteristics, only need to replenish the original solution when using, and do not need to replace the whole tank; the quenching agent of the present invention solves the problem of PAG quenching agent in the low temperature zone of martensite transformation temperature. When used at high temperature, there is a problem that inverse solubility cannot be used

Embodiment 1

[0024] An oil-like water-based quenching agent that replaces quenching oil, including the following raw materials in parts by weight: 4 parts of polyether, 1 part of sodium polymaleate, 0.5 parts of isopropanol, 2 parts of maleic acid, citric acid 1 part of sodium, 0.1 part of triethanolamine, 3 parts of sodium benzoate, 10 parts of water.

Embodiment 2

[0026] An oil-like water-based quenching agent that replaces quenching oil, including the following raw materials in parts by weight: 8 parts of polyether, 2 parts of sodium polymaleate, 1 part of isopropanol, 4 parts of maleic acid, citric acid 3 parts of sodium, 0.2 parts of triethanolamine, 4 parts of sodium benzoate, and 15 parts of water.

Embodiment 3

[0028] An oil-like water-based quenching agent that replaces quenching oil, including the following raw materials in parts by weight: 14 parts of polyether, 4 parts of sodium polymaleate, 1.5 parts of isopropanol, 5 parts of maleic acid, citric acid 5 parts of sodium, 0.3 parts of triethanolamine, 5 parts of sodium benzoate, 20 parts of water.

[0029] The quenching agent of the present invention is a colorless or light yellow transparent liquid with a pH value of 7. This product is easily soluble in water, and its concentration is easy to measure and control. By changing different concentrations, different quenching speeds from water to oil can be obtained; by controlling the concentration , long-term stable quenching and cooling characteristics can be obtained.

[0030] The method of using the product of the present invention: Proportion the original solution of the quenching agent with water, the ratio of the original solution and water is between 1:4 and 1:20, and the rati...

Abstract

The invention discloses an oil-like type water-based quenching agent for replacing quenching oil. The oil-like type water-based quenching agent has the characteristics of being free from counter-solubility, nontoxic smogless, incombustible, free from fire risk, free from pollution, free from corrosion, free from ageing, and long in service life. A stock solution is supplemented, rather than replacing the whole cell during use. The quenching agent solves the problems that a PAG quenching agent is excessively fast cooled in a low temperature area of martensite transformation temperature, and counter-solubility occurs under the temperature beyond 70 DEG C and influences the use.

Description

technical field [0001] The invention belongs to the field of quenching agents, in particular to an oil-like water-based quenching agent instead of quenching oil. Background technique [0002] Quenches are water-soluble solutions of liquid organic polymers and corrosion inhibitors. The quenching agent is mainly used for all kinds of carbon steel, low alloy structural steel, spring steel, carburizing steel, and bearing steel workpieces for body-increasing immersion quenching and induction heating quenching. When cooling hot metal with a dilute solution of quenching agent, the liquid organic polymer will deposit on the metal surface, forming a thin film, and the cooling can be controlled by adjusting the temperature or stirring degree of the quenching liquid. At present, steel parts are easily quenched and cracked when using a quenching agent, which causes huge waste and also causes environmental pollution. Moreover, in use, the organic solution will accelerate aging after bei...
