Abstract

The present invention discloses a synthetic aqueous quenching liquid and a use method thereof. Raw materials of the lubricating oil comprise, by weight, composite PAG, a cooling accelerant, and an antioxidant. The synthetic aqueous quenching liquid has the following advantages that: high difficulty heat treatment requirements of aqueous quenching are met; hardness HRC is in a range of 28-63, and can be randomly adjusted; metallography can be 3-5 grade; non-renewable energy source utilization is reduced; compared with the traditional quenching oil, the oil is saved by 80-90% with the synthetic aqueous quenching liquid of the present invention; magnetic inspection results show that no quenching crack is generated, hardness is moderate, and the metallography structure is qualified and meets enterprise production needs and harsh machining requirements; a quench-hardened layer of the quenching liquid is deep, quenching hardness is uniform, and no soft spot is generated, such that tendencies of quenching deformation and cracking are substantially reduced; no corrosion is generated to ferrous metals and nonferrous metals; the resulting quenched workpiece has characteristics of brightness, short-term antirust, aging resistance, deterioration resistance and long service life; and the synthetic aqueous quenching liquid further has characteristics of no toxicity, no oil fume, no burning, no fire disaster risk, safe use, improved working environment, and no environmental pollution.

Description

technical field [0001] The invention relates to a quenching cooling medium, in particular to a synthetic water-based quenching liquid added with synthetic composite PAG and capable of replacing mineral oil, and a use method thereof. Background technique [0002] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. Quenching is one of the processing techniques of heat treatment. After the workpiece is heated and kept warm, it is rapidly cooled in water, oil or other inorganic salts, organic aqueous solutions and other quenching media. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness and wear resist...
