Abstract

The present invention relates to a novel over-speed bright quenching oil composition, which contains mineral lubricating oil, a cooling accelerant, anti-oxidation additives and brightening additives. The quenching oil has good cooling properties, heating stability, oxidation stability and brightness. The preparation process of the quenching oil is simple, and the raw materials are domestic and therefore easy to get with low price. The quenching oil is suitable for the quenching of spring steel, bearing steel and mold steel and large-sized steel, particularly for the quenching of small-sized and medium-sized carbon tool steel.

Description

technical field [0001] The invention relates to a quenching oil for metal heat treatment, in particular to a novel super-speed bright quenching oil composition and a preparation method thereof. Background technique [0002] Quenching oil is a process oil used as a quenching medium. Quenching oil must have the following characteristics: Good cooling performance 1. Cooling performance is an important performance of quenching medium. Its quality directly affects the quality of quenched parts. Good cooling performance can ensure that the quenched parts have a certain hardness and pass 2. High flash point and ignition point. When quenching, the temperature of the oil will rise instantaneously. If the flash point and ignition point of the oil are low, ignition may occur. Therefore, the quenching oil should have a higher flash point and ignition point. Generally, the flash point should be 60-80°C higher than the temperature of the used oil; 3. Good thermal oxidation stability. Qu...
