Abstract

The invention discloses chain piece specific quenching oil and a quenching method thereof. The invention belongs to the field of metal heat treatment technology. The quenching oil comprises the following components, by weight, 35-40 parts of refined base oil, 7-10 parts of cooling catalyzed composite agent, 0.5-0.7 parts of blackening composite agent, 0.4-0.8 parts of brightening agent, 0.5-0.8 parts of surface activating agent and 0.02-0.04 parts of antioxidant. The effect of is best when the maximum cooling speed of the quenching oil for the chain piece is about 93-102 DEG C / s and the using temperature is 70-80 DEG C. Under the above conditions, the ideal quenching hardness can be obtained, the deformation rate is low, the effect of the automatic surface blackening can be realized, a protective film formed on the surface is strong in adhesion and not easy to fall off, and the effect of the appearance beautification and short-term rust prevention can be realized. Once more surface coating and rust preventing treatment after the heat treatment can be reduced, so that the resources can be saved, the processes can be reduced and the efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment, and more specifically relates to a special quenching oil for chain segments and a quenching method thereof. Background technique [0002] Chains are generally metal links or rings, which are mostly used for mechanical transmission and traction. From the perspective of the structure of the chain, most chains are composed of chain pieces, chain pins, bushings and other components. Other types of chains just make different changes to the chain pieces according to different needs. The chain is mainly used for mechanical transmission, so it has to bear huge friction force. Therefore, it needs heat treatment to improve its hardness, wear resistance and service life. Quenching is a commonly used heat treatment process, which refers to the process of heating the workpiece to a certain temperature for a period of time, and then cooling the workpiece with quenching oil to complete the transf...
