Problems solved by technology

Disadvantages of existing quenching oil: when quenching, the temperature of the oil will rise instantaneously. If the flash point and ignition point of the oil are low, fire may occur; excessive moisture in the oil will affect the heat treatment quality of the parts, resulting in soft spots of the parts , Quenching cracking or deformation may also cause oil splashing and accidents; the steam film stage lasts for a long time, which will lead to parts after quenching and cooling: uneven cooling, uneven hardness and softness of parts, large quenching deformation; and quenching The final parts cannot meet the required mechanical properties; the effective life of quenching oil is short
At present, quenching oil often has a large amount of scale or impurities deposited in the oil due to repeated use, and new oil must be replaced, resulting in an increase in the cost of quenching oil

Abstract

Recyclable quenching oil is prepared from, by weight, 85-95 parts of 500N II-type base oil, 5-15 parts of oily phenolic resin, 5-15 parts of terpene resin, 10-12 pars of 42% chlorinated paraffin, 1-3 parts of triethanolamine, 1-3 parts of zinc dialkyl dithiophosphates, 5-10 parts of polyoxyethylene rosin ester, 0.5-4 parts of poly-alpha-alkene, and 3-4 parts of modified antioxidants. The recyclable quenching oil is low in viscosity and good in gloss; oxide skin and other impurities generated in the quenching process can easily sink to the oil bottom and are convenient to remove, and therefore the quenching oil can be used for a long time; moreover, the quenching oil is not prone to adsorption of water and is low in oxygen dissolving rate, resistant to mould breezing, stable in oil product composition and quite low in volatilization rate at a high temperature, and the cyclic utilization rate of the quenching oil is increased.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a quenching oil for recycling. 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. [0003] Iron and steel parts that have u...
