Abstract

The invention provides a water-based quenching agent of alloy steel, which comprises the following compositions in parts by weight: 6-8 parts of sodium bicarbonate, 20-25 parts of glucose, 1-2 parts of acetic acid, 3-4 parts of sodium hydroxide, 4-6 parts of a foaming agent, 1-2 parts of a stabilizer, and 100 parts of water. The invention further provides a water-based quenching agent of another kind of alloy steel, which comprises the following compositions in parts by weight: 6-8 parts of sodium bicarbonate, 20-25 parts of glucose, 1-2 parts of acetic acid, 4-6 parts of starch, 3-4 parts of sodium hydroxide, 4-6 parts of a foaming agent, 1-2 parts of a stabilizer, and 100 parts of water. The water-based quenching agent of the alloy steel, provided by the invention, is low in cost, not easy to cause fire, and pollution-free, can be directly used, and is in no need of temporary preparation.

Description

technical field [0001] The invention belongs to the technical field of heat treatment and quenching, and in particular relates to a water-based quenching agent for alloy steel. Background technique [0002] The traditional single-medium quenching of alloy steel is continuous cooling, and the coolant is generally oil. Because oil quenching will cause a certain degree of pollution to the environment, and there is a risk of fire, in recent years, more and more companies have given up using oil quenching in heat treatment, and used various water-soluble polymer organic solutions as alloy steel Quenching cooling medium. However, although this type of water-soluble organic cooling medium does not produce serious pollution and fire hazards when it is used for quenching, the market price is still high, and the storage period of the original medium is limited. It can be used only when it is formulated into an aqueous solution in a certain proportion. In use, the organic matter solu...
