Abstract

The invention discloses a quenching oil preparation method, belonging to the technical field of heat treatment and surface treatment of metals. The quenching oil comprises the following components in parts by weight: 17-19 parts of refined base oil, 0.2-0.6 part of cooling accelerating composite agent, 0.1-0.3 part of blackening composite agent, 0.2-0.5 part of brightening agent and 1-2 parts of surfactant. The quenching oil prepared by the preparation method has the advantages of good dispersibility, good stability, good heat transmissibility, and the like, can ensure that bearing steel parts (including bearing rings, rollers and retainers) automatically blacken after quenching, not only can obtain ideal quenching hardness and metallographic structures and achieve the mechanical strength and toughness required by workpieces but also can achieve the effect that the surfaces automatically blacken, and is conducive to reducing coating and rust-proof retreatment of the surfaces after heat treatment, saving energy, reducing procedures and improving the efficiency.

Description

Technical field [0001] The invention belongs to the technical field of metal heat treatment and surface treatment, and more specifically, relates to a method for preparing quenching oil. Background technique [0002] Metals usually use heat treatment to improve the strength and metallographic structure of the metal to obtain the desired properties, and the quenching medium is one of the key factors to obtain high quenching quality. Commonly used quenching media include brine, water, and minerals. Oil, air, etc. Blackening is a common method of chemical surface treatment. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. In the prior art, quenching and blackening treatment are two different processes. Due to different requirements for quenching medium and blackening liquid, it is difficult to perfectly combine the two processes of heat treatment and surface blackening treatment to save resources.
