Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment cooling, in particular to an intelligent rapid circulation device for cooling liquid in a quenching pool. Background Art

[0002] Forging workpieces are generally used as basic blanks for the manufacture of large equipment. They need to withstand great bending and compressive strength. At the same time, the surface of the forged workpieces needs to have high surface hardness and high wear resistance to meet the operating requirements and service life of large equipment. In the process of forging workpieces, quenching technology is a necessary process technology. In order to improve the strength, hardness and wear resistance of the forged workpiece itself, the austenite of the forged workpiece is transformed into bainite, thereby improving the quality of the forged workpiece.

[0003] As the cooling medium in the quenching process, the coolant plays an important role in the quenching process. The quenching liquid in the quenching pool undergoes multiple quenching cooling. The coolant absorbs the heat in the quenching workpiece, causing the temperature of the coolant in the quenching pool to gradually rise. When the temperature of the quenching coolant reaches a certain temperature, it will affect the cooling effect of the coolant.

[0004] In the prior art, in the general workpiece processing field, the cooling of the coolant is generally achieved by stirring; the main problems of this cooling method are: 1. The stirring method has a poor cooling effect on the coolant and the coolant cannot circulate; 2. The stirring method cannot accurately control the temperature of the coolant and the degree of automation is not high; based on the defects in the prior art, the inventor has developed an automatic circulation cooling device for the quenching pool coolant, which can well solve the problems existing in the prior art.
