Water-soluble quenching agent

Abstract

The invention provides a water-soluble quenching agent. The water-soluble quenching agent is prepared from the following raw materials of, by weight, 5-8 parts of a surfactant, 42-45 parts of polyether, 0.1-0.3 part of a defoamer, 0.2-0.5 part of a sterilizing agent, 35.7-47.5 parts of water, and 5-10 parts of sodium benzoate. Compared with the prior art, the water-soluble quenching agent has thefollowing beneficial effects that the quenching degree of materials can be met and controlled so as to avoid cracks of the materials; environment-friendly water-based quenching liquid with the high-quality polyether as a base is composited with the balanced surfactant, defoamer and sterilizing agent, thus the extremely large cooling rate is achieved at the high-temperature cooling stage, grains can be refined, and the final performance of a quenched workpiece is improved; and at the low-temperature cooling stage, the moderate cooling rate is achieved, so that the problems of cracking, deforming and the like in the workpiece cooling process are effectively solved, and the machining accuracy and surface quality of the workpiece are improved.

Description

technical field [0001] The invention relates to a water-soluble quenching agent, which relates to the technical field of metal heat treatment, in particular to a water-soluble quenching liquid used for quenching and cooling carbon steel and alloy steel parts. Background technique [0002] At present, the most commonly used quenching media in the heat treatment process of the machinery industry are water-based quenching agents and mineral quenching oils; quenching oils are likely to pollute the environment during the quenching process, generate a lot of smoke, and affect the health of operators. In addition, the flash of mineral oil Low point, easy to fire, unsafe to use; water-soluble quenching agent is to dissolve the organic polymer solvent in water, and adjust the concentration and temperature of the solution to meet the cooling performance of the quenching agent. The water-soluble quenching agent has a high cooling rate during the entire cooling process. In the high-temp...

[0002] At present, the most commonly used quenching media in the heat treatment process of the machinery industry are water-based quenching agents and mineral quenching oils; quenching oils are likely to pollute the environment during the quenching process, generate a lot of smoke, and affect the health of operators. In addition, the flash of mineral oil Low point, prone to fire, unsafe to use; water-soluble quenching agent is to dissolve the organic polymer solvent in water, and adjust the concentration and temperature of the solution to meet the cooling performance of the quenching agent

The water-soluble quenching agent has a high cooling rate during the entire cooling process. In the high-temperature cooling stage, it can promote grain refinement and regular crystal form, which is conducive to improving the performance of the work. However, in the low-temperature stage, excessive cooling speed is easy to Lead to workpiece cracking, quenching deformation and other problems
