Description

Technical field [0001] The invention belongs to the field of petrochemical workers, involving a quenching oil, specifically an environmentally friendly high temperature isothermal hierarchical quenching oil and a preparation method thereof. Background technique [0002] With the advancement of the times, the current society has put forward higher requirements for mechanical metal materials - without significant increase in the cost of guarantee, not only requires high strength and hardness, but also has good comprehensive mechanical properties. Quenching is an important process in the process of mechanical manufacturing materials. The so-called quenching is a certain temperature heated to the austenite transformation point, maintains a certain time, then cools the martensite and (or) Bethe The heat treatment process of body tissue. The purpose of quenching is to increase the hardness, strength, wear resistance, toughness, fatigue strength, and corrosion resistance of steel, so th...
