Problems solved by technology

If the quenching cooling rate is too slow, the workpiece cannot obtain the ideal quenching hardness and hardened layer depth; if the cooling rate is too fast, it may cause quenching cracks and too deep hardened layer
Too fast or too slow quenching cooling rate will also cause out-of-tolerance deformation of the workpiece

Abstract

The invention relates to a novel water-based inorganic quenching agent which is characterized by being prepared from the following components in percentage by weight: 0.1 to 10 percent of glycerol, 0.1 to 10 percent of diethanol amine, 0.1 to 10 percent of triethanolamine, 0.1 to 10 percent of sodium benzoate, 0.1 to 10 percent of sodium formate, 0.005 to 1 percent of sodium hydroxide and the balance of water. The quenching agent provided by the invention is high in cooling speed in a high-temperature stage and relatively low in cooling speed in a low-temperature stage, so that the quenching agent can satisfy the hardenability of a material and also prevent relatively high internal stress from being generated in a workpiece; therefore, the performance of the workpiece is improved; and furthermore, the quenching agent is safe, environmentally friendly, colorless, tasteless, sediment-free, non-combustible, pollution-free, inverse solving-free and low in use cost, and little quenching agent can be brought out.

Description

technical field [0001] The invention relates to the field of metal heat treatment, in particular to a high-efficiency, environment-friendly, safe and low-cost quenching agent. Background technique [0002] In the production process of metal heat treatment, quenching is to use rapid cooling to obtain the ideal martensitic structure of the workpiece. If the quenching cooling rate is too slow, the workpiece cannot obtain the ideal quenching hardness and hardened layer depth; if the cooling rate is too fast, it may cause quenching cracks and too deep hardened layer. Quenching cooling speed is too fast or too slow, and it will also cause out-of-tolerance deformation of the workpiece. Therefore, the quenching agent is required to have the characteristics of "cooling at high temperature quickly and cooling at low temperature slowly". The goal of developing a new type of quenching agent is to reduce the cooling rate of water at low temperatures and increase the cooling rate at hig...
