Abstract

The invention relates to a spring steel quenching agent which is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of magnesium lithium silicate, 0.01-0.02 part of benzotriazole, 0.2-0.4 part of polyglutamic acid, 1-2 parts of maltodextrin, 3-5 parts of sodium chloride, 2-4 parts of alums, 0.2-0.4 part of perfluorooctane sodium sulfonate, 0.1-0.2 part of dioctyl sodium sulfosuccinate, 0.3-0.5 part of pentaerythritl tetraisostearate, 0.1-0.2 part of tartaric acid, 3-5 parts of assistants and 70-80 parts of water. The quenching agent provided by the invention has a good cooling performance, can effectively reduce deformation and cracking of workpieces and improve the strength and toughness of the workpiece, has a certain rustproof function, and is suitable for a quenching process of the spring steel.

Description

technical field [0001] The invention relates to heat treatment technology, in particular to a spring steel quenching agent and a preparation method thereof. Background technique [0002] Quenching is a process in which a metal workpiece is heated above the phase transition temperature, and then rapidly cooled in a quenching medium after heat preservation to obtain a martensitic structure. Through the quenching process, the purpose of improving or adjusting the hardness and wear resistance of the workpiece can be achieved. In this process, the requirements for the quenching medium (quenching agent) are to avoid deformation and cracking of the workpiece; the quenching agent is easy to clean, does not pollute and corrode the surface of the workpiece; has stable performance, high temperature resistance, aging resistance, and is not easy to deteriorate; easy to prepare and transport And storage, safe use; raw materials are easy to get, and the cost is low. [0003] Generally, q...
