Embodiment 1～5

[0024] Pump the base oil into the blending kettle, turn on the agitator and the heating switch, and when the oil is heated to 65°C, add the required amount of each component in turn, and continue to heat and stir at 65°C for 3 hours to obtain a uniform black liquid. The components and content of the anti-emulsification type overspeed quenching oil composition are shown in Table 1, and the corresponding performance index results are shown in Table 2 and Table 3.

[0025] By adopting the test method of ISO 9950, the cooling performance of each quenching oil composition was measured by using an IVF quenchotest cooling performance tester.

Abstract

The invention relates to an anti-emulsification type overspeed quenching oil composition and application thereof, and mainly relates to overspeed quenching oil with good oil-water separation and excellent cooling performance. The anti-emulsification performance of the overspeed quenching oil in the prior art is improved, and the oil-water separation performance is enhanced so as to solve the problem of emulsification of the overspeed quenching oil in the cleaning process of quench workpieces in the prior art. The anti-emulsification type overspeed quenching oil composition comprises, by weight, (a) 0.5-10 parts of cooling agents, (b) 0.1-3 parts of antioxidants, (c) 0.05-1 part of brightener and (d) 75-95 parts of base oil. The anti-emulsification type overspeed quenching oil composition can be used for quenching workpieces which require high emulsifying performance and have high thickness, large cross section and low hardenability, such as automobile fasteners, gears, bearings and seamless steel pipes.

Description

technical field [0001] The invention relates to an anti-emulsification type overspeed quenching oil composition and its application. Background technique [0002] Quenching is heating the steel to A c3 or A c1 It is a heat treatment process to obtain a martensite and (or) bainite structure by cooling at a certain temperature above the point 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...
