Abstract

The invention discloses an efficient and energy-saving quenching liquid. The efficient and energy-saving quenching liquid comprises the following components of, by mass, 5%-8% of polyvinyl alcohol, 1%-5% of a cooling accelerant, 1%-5% of polyether, 2%-6% of sodium phosphite, 2%-4% of a scale inhibitor, 0%-2% of an antirust agent and the balance water. The efficient and energy-saving quenching liquid has the advantages of safety, environmental protection, corrosion inhibition and long service life, the quenching liquid overcomes the problem that a traditional quenching liquid is quick to cool but prone to cracking, and the quality of steel products is effectively improved.

Description

technical field [0001] The invention relates to the technical field of quenching liquid, in particular to a high-efficiency and energy-saving quenching liquid. 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 s...
