Abstract

The invention discloses novel rapid bright quenching oil. The oil comprises, by weight fraction, base oil, a catalyst cold agent, an antioxidant, a scaling inhibitor, animal and vegetable oil and a brightening agent. The scaling inhibitor is a single-handing ash-free dispersing agent T151 or polyisobutene bissuccinimide T154 or high molecular weight polyisobutene bissuccinimide T16, the brightening agent is Mirilline oleate or mushroom ene acetic acid or zinc butyl octyl dithiophosphate T202; the antioxidant is a mixture of an amine antioxidant and a phenolic antioxidant; the amine antioxidantis selected from at least one of alkylated diphenylamines, alkyl phenyl-alpha-naphthylamine or N-phenyl group-N'-alkyl group-P-phenylene dI amine. Through sintering, the oil has the good cooling, brightness and thermal oxidation stability, the cooling time is short, the cooling capacity is good, meanwhile, the brightness level can reach A, the metal luster can be effectively improved, the qualityof the treated metal is improved, and a quenched workpiece is bright in surface and free of cracking.

Description

technical field [0001] The invention relates to the field of quenching oil, in particular to a novel fast bright quenching oil. Background technique [0002] Quenching is a heat treatment process in which steel is heated to a certain temperature above the Ac3 or Am point, kept for a certain period of time, and then cooled at an appropriate rate to obtain martensite and (or) bainite. Quenching is an important link in mechanical manufacturing and processing. The purpose of quenching is to improve the hardness, strength and wear resistance to improve the performance of parts. Quenching medium is the cooling medium for heat treatment of metal parts, including air, water, quenching oil and water-based quenching fluid. Among them, quenching oil is currently used in the largest amount and is widely used in industries such as automobiles, tooling, bearings, fasteners, wind power and household appliances. [0003] Quenching oil is often used in quenching. The quenching oil in the p...
