Abstract

The invention discloses high-performance quenching oil, and belongs to the field of quenching cooling media. An oil-based quenching oil raw material for preparing the high-performance quenching oil isinfluenced by a benzene ring substituent group and the carbon atom number, a straight chain structure of the oil-based quenching oil raw material is low in pour point and better in thermal stability,and the lubricating performance and the dispersing performance of an oil base are improved on account of an introduced polar benzene ring; a cooling adjusting additive used for preparing the high-performance quenching oil is used for decreasing the low-temperature cooling speed of water and reducing deforming and cracking of a workpiece, when the temperature is lowered to a turbidity point or below, the cooling adjusting additive which is separated out is dissolved into the water again, the temperature condition in the quenching process is achieved, and damage of overheating to the workpieceis prevented; and through a flash point adjusting active agent for preparing the high-performance quenching oil, the viscosity of the oil base is adjusted, the condition that the quenching oil loses the efficacy due to the fact that gel is formed is prevented, the heat resistance of the oil base is improved, therefore, the flash point and the ignition point are increased, and the using performanceof the quenching oil is improved. According to the high-performance quenching oil, the problems that existing quenching oil is poor in cooing performance and low in flash point are solved.

Description

technical field [0001] The invention relates to the technical field of quenching cooling medium, in particular to a high-performance quenching oil. Background technique [0002] Chemical heat treatment is a heat treatment process that puts a metal or alloy workpiece in an active medium at a certain temperature to keep one or several elements infiltrated into its surface to change its chemical composition, structure and performance. Chemical heat treatment uses chemical reactions and sometimes physical methods to change the chemical composition and structure of the steel surface in order to obtain a metal heat treatment process with better technical and economic benefits than homogeneous materials. Since most of the failure and damage of mechanical parts germinate in the surface layer, especially for parts that may cause wear, fatigue, metal corrosion, oxidation and other conditions, the performance of the surface layer is particularly important. Iron and steel parts that ha...
