Problems solved by technology

When quenching, using oil as a quenching medium is only suitable for quenching some alloy steels or small-sized carbon steel workpieces with relatively high stability of supercooled austenite, and mineral oil is a non-renewable energy source, which has high economic costs and wastes resources.
However, due to the unsatisfactory quenching effect and unsatisfactory heat treatment performance of the traditional water-based quenching liquid, cracks and deformation are prone to occur during the quenching process, which seriously restricts production.

Abstract

The invention provides a quenching agent for improving the wear resistance of a bearing ring component and a preparation method of the quenching agent and relates to the technical field of quenching agents. The quenching agent provided by the invention is prepared from the following raw materials of: sodium molybdate, p-cresol, amino silicon oil, decyl Polyglucoside, sodium ethylene diamine tetracetate, sodium chloride, barium chloride, oleamide, a preservative agent, a defoaming agent, a bactericide, polyvinyl acetate, sodium hydroxide and deionized water. The quenching agent for improving the wear resistance of the bearing ring component can greatly improve the wear resistance of the bearing ring component, is good in quenching effect and low in quenching cost, can reduce the quenching speed, can prevent formation of relatively large internal stress inside the bearing ring component, and prevents cracking of the bearing ring component.

Description

technical field [0001] The invention relates to the technical field of quenching agents, in particular to a quenching agent for improving the wear resistance of bearing ring components and a preparation method thereof. Background technique [0002] With the continuous development of current technology, especially the requirements for the mechanical properties of products are getting higher and higher. In the process of processing and production, alloys often appear in the process of production and processing. The wear resistance and hardness of castings have an important impact. The wear and tear during the use of equipment and machinery will cause hidden dangers in the operation of mechanical equipment, especially in the process of engineering and mining machinery, which often have severe wear and tear with hard ore, which greatly reduces the use of steel and causes important waste. [0003] Generally, to improve the wear resistance of steel, it is mainly to change the c...
