Abstract

The invention relates to a quenching oil composition and application thereof. The problems that in the prior art, the cooling performance of a high-medium-temperature zone of super-speed quenching oil is insufficient, and the cooling speed of a low-temperature zone of the super-speed quenching oil is too high are mainly solved. The quenching oil composition comprises, by weight, (a) 0.5-10 parts of a cooling accelerant, (b) 0.1-3 parts of an antioxidant, (c) 0.01-1 part of a metal deactivator, and (d) 75-95 parts of base oil. By means of the technical scheme, the problems are well solved, and the quenching oil composition can be used for quenching automobile plate spring parts.

Description

technical field [0001] The present invention relates to a quenching oil composition and its use. Background technique [0002] Quenching is the heating of steel to A c3 or A c1 A heat treatment process in which martensite and (or) bainite structure are obtained by cooling at a certain temperature above the point, maintaining it for a certain period of time, and then cooling at an appropriate rate. Quenching is an important link in mechanical manufacturing and processing. The purpose of quenching is to improve the hardness, strength and wear resistance to improve the performance of parts. Quenching medium is the cooling medium for heat treatment of metal parts, including air, water, quenching oil and water-based quenching fluid. Among them, quenching oil is currently used in the largest amount and is widely used in industries such as automobiles, tooling, bearings, fasteners, wind power and household appliances. [0003] In recent years, with the emergence of new heat tre...
