Abstract

The invention provides environment-friendly high-temperature isothermal step quenching oil. The environment-friendly high-temperature isothermal step quenching oil is prepared from 150BS bright oil, acooling accelerant, an antioxidant, a brightener, an antirust agent and an anti-foaming agent. The invention further provides a preparation method of the environment-friendly high-temperature isothermal step quenching oil. The oil has the most remarkable characteristics that high-temperature cooling is fast, low-temperature cooling is gentle, the flash point is high, the use temperature is high,the thermal oxidation resistance is good, the service life is long, the brightness and anti-rust performance are excellent, and the technical index requirements of the petrochemical industry standardSH / T 0564-93 heat treatment oil No. 2 isothermal step quenching oil in China are met. In addition, the production preparation process is simple, and the product is environment-friendly and stable in quality.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a quenching oil, in particular to an environment-friendly high-temperature isothermal graded quenching oil and a preparation method thereof. Background technique [0002] With the progress of the times, the current society has put forward higher requirements for mechanical metal materials - not only high strength and hardness, but also good comprehensive mechanical properties are required under the condition of ensuring that the cost does not increase significantly. Quenching is an important process in the processing of mechanical manufacturing materials. The so-called quenching is to heat the steel to a temperature above the austenite transformation point, keep it for a certain period of time, and then cool it at an appropriate speed to obtain martensite and (or) bainite. Body tissue heat treatment process. The purpose of quenching is to improve the hardness, strength, wear r...
