Problems solved by technology

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 being heated, which will change its cooling characteristics. If it is not replaced in time, It will reduce the quality of heat treatment products, even unqualified, frequent replacement of quenching agent, high cost and low efficiency

Embodiment 1

[0024] A quenching agent for special steel, comprising the following raw materials in parts by weight: 4 parts of polyether, 1 part of sodium carbonate, 0.5 part of polyvinyl alcohol, 2 parts of boric acid, 1 part of starch, 0.1 part of triethanolamine, 3 parts of sodium benzoate, 10 parts of water share.

Embodiment 2

[0026] A quenching agent for special steel, comprising the following raw materials in parts by weight: 8 parts of polyether, 2 parts of sodium carbonate, 1 part of polyvinyl alcohol, 4 parts of boric acid, 3 parts of starch, 0.2 part of triethanolamine, 4 parts of sodium benzoate, 15 parts of water share.

Embodiment 3

[0028] A quenching agent for special steel, comprising the following raw materials in parts by weight: 14 parts of polyether, 4 parts of sodium carbonate, 1.5 parts of polyvinyl alcohol, 5 parts of boric acid, 5 parts of starch, 0.3 part of triethanolamine, 5 parts of sodium benzoate, 20 parts of water share.

[0029] 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 to water is between 1:4 and 1:20, and the ratio can be set according to requirements. The invention belongs to the synthetic quenching agent of high molecular organic matter, with neutral PH, non-toxic, non-combustible, and the cooling speed characteristic of the aqueous solution with the ratio of 1:4-1:6 is between the wind ten spray cooling speed and the slow speed The cooling rate of quenching oil is between 30°C / s-60°C / s, and the cooling rate at 300°C is close to that of oil, which solves the problem ...

Abstract

The invention discloses a special steel quenching agent. The special steel quenching agent is non-insoluble, small in consumption, energy-saving, non-combustible, safe, pollution-free, environment-friendly, free of aging after being used for a long time, and stable in performance, and only original liquid needs to be supplemented during use without replacing the quenching agent of the whole groove; and by adopting the quenching agent, the problems that the workpiece quenching crack is caused by quenching through slow quenching oil, and the hardness of the workpiece is low due to spray quenching are solved.

Description

technical field [0001] The invention belongs to the field of quenching agents, and in particular relates to a quenching agent for special steel. 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 being heated, which ...
