Problems solved by technology

The preparation process of the quenching agent in the prior art is complicated and the performance is poor. Although it can prevent the workpiece from cracking due to excessive internal stress at the low temperature stage, due to the slow cooling rate at the high temperature stage, it is easy to cause large grains of the workpiece and reduce the quality of the workpiece. Properties after quenching

Abstract

The invention discloses a quenching agent for workpiece treatment and a preparation method of the quenching agent. The quenching agent is prepared from, by weight, 20-40 parts of polyether, 10-20 parts of triethanolamine, 5-15 parts of sodium molybdate, 5-10 parts of calcium sulfonate, 8-17 parts of polyvinyl acetate, 8-15 parts of defoaming agent, 5-16 parts of polyamide polyethylene glycol and 10-20 parts of deionized water. The preparation process is simple, environmentally friendly, free of pollution and low in manufacturing cost, the prepared quenching agent can decrease the cooling speed and can prevent large inner stress from being formed in a workpiece, and therefore the purpose of preventing the workpiece from being cracked is achieved.

Description

technical field [0001] The invention relates to the technical field of quenching agent preparation, in particular to a quenching agent for workpiece heat treatment and a preparation method thereof. Background technique [0002] In order to obtain steels with different properties, it is necessary to improve the properties of metal materials. Usually, heat treatment is performed on metal workpieces. Commonly used heat treatment processes include quenching, tempering, annealing, normalizing and other heat treatment methods. Among them, quenching refers to, for example, rapidly cooling a workpiece heated to an austenite state at a speed above the critical cooling rate to form a quenched structure such as martensite. After quenching, the hardness of the workpiece can be increased. In the quenching process, the cooling process of the workpiece is generally divided into three stages, namely, the first stage (steam film stage) in which the metal material is surrounded by the vapor o...
