Abstract

The invention discloses easily-cleaning bright quenching oil special for a bearing and a preparing method of the easily-cleaning bright quenching oil and belongs to the technical field of metal heat treatment. According to the formula, the quenching oil includes 0.2-0.4 part of a dispersing agent, and the dispersing agent is a mixture of liquid paraffin and lauryl sodium sulfate. The dispersing agent comprises, by mass, 33-40 parts of refined base oil, 4-7 parts of cooling agents, 0.2-0.5 part of a brightening agent, 0.02-0.04 part of an antioxidant and 0.3-0.7 part of a surface active agent.The refined base oil, the surface active agent and the antioxidant are evenly mixed, then, the brightening agent and a dispersing agent are added at the same time, stirring is even, finally, the catalysts are added in the manner that adding is conducted while stirring is conducted, stirring is conducted till the uniform state is reached, then the mixture is subjected to standing to reach the roomtemperature, and quenching oil is obtained. By means of the easily-cleaning bright quenching oil special for the bearing and the preparing method of the easily-cleaning bright quenching oil, the brightening agent and the dispersing agent are cooperatively used, and the color problem in the whole workpiece heat treatment process can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment, and more specifically relates to an easy-to-clean bright quenching oil for bearings and a preparation method thereof. Background technique [0002] With the development of high-end intelligent equipment, the requirements for the quality of products in the heat treatment industry are also getting higher and higher, especially for precision parts such as bearings and gears. As a commonly used precision part, bearings have very strict product requirements. It is necessary to control the deformation of the bearing while ensuring the hardness and metallographic structure are qualified. At present, there are many reports on improving bearing deformation, but there are almost no research reports on improving bearing color. In the past two years, the bearing industry has very strict requirements on the color of bearings after heat treatment. At present, the commonly used quenching medium f...
