Synthetic quenching liquid and using method thereof

Abstract

The invention discloses a synthetic quenching liquid and a using method thereof. The synthetic quenching liquid comprises the following raw materials in percentage by weight: 83-88% of compound PAG, 10-15% of a cooling accelerant, 1.5-2% of an antioxidant and 0.5-1.5% of a defoaming agent. Through the adoption of the synthetic quenching liquid and the using method thereof, the requirement of high-difficulty heat treatment of quenching can be met, and the hardness HRC can be adjusted optionally within the range of 35-63; the synthetic quenching liquid saves oil compared with traditional quenching oil; and magnetic flaw detection shows that no quenching crack is caused and the hardness is moderate, and the metallographic structure is qualified and meets the requirement. The synthetic quenching liquid has the effects of deep hardening zone, uniform quenching hardness and no soft spot, greatly reduces the tendency of quenching deformation and cracking, cannot corrode ferrous metals or nonferrous metals, makes a quenched workpiece bright, has a short-term antirust effect, cannot age or go bad easily, has a long service life, is incombustible, is safe to use, improves the working environment, causes no environment pollution, greatly improves the processing quality of quenched surfaces and the production efficiency and reduces the production costs of enterprises.

Description

technical field [0001] The invention relates to the technical field of heat treatment and quenching, in particular to a synthetic quenching liquid and a method for using the same.
