Abstract

The invention discloses quenching liquid with an anti-corrosion effect. The quenching liquid comprises, by mass percent, 4 to 8% of an antioxygen, 1 to 3% of octanoic acid, 1 to 3% of an anti-corrosion agent, 2 to 6% of a scale restraining agent, 1 to 4% of an antifoaming agent, 0 to 2% of an antioxidant and the balance water. The quenching liquid has the advantages of being safe, environment-friendly, capable of achieving corrosion inhibition, and long in service life, the quenching liquid solves the problem that traditional quenching liquid is rapid in cooling and prone to cracking, and quality of a steel product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of quenching liquid, in particular to a quenching liquid with anti-corrosion effect. Background technique [0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. The purpose of quenching is to improve the strength and hardness of metal workpieces, increase wear resistance, and obtain workpieces with excellent comprehensive mechanical properties with high strength and hardness, certain elasticity and toughness through tempering treatment. [0003] Commonly used quenching media are brine, water, mineral oil and air. The quenching process is mainly used for steel parts. When the commonly used steel is heated above the critical temperature, all or most of the original structure at room temperature will be transformed into austenite, and then the steel is...
