Background
The quenching of steel is a heat treatment process for heating steel to a set temperature, preserving heat for a certain time, and then rapidly cooling down to obtain high hardness and high strength. In order to obtain a sufficient cooling rate in quenching, it is necessary to select an appropriate quenching cooling medium, and examples of the commonly used quenching cooling medium include water, brine, alkaline water, oil, and the like. In order to ensure the quenching quality, it is important to correctly select a quenching cooling medium and to ensure that the cooling medium can be kept at a constant temperature all the time in the continuous quenching process so as to ensure that the steel obtains a stable supercooling degree in a high-temperature austenite state. Therefore, a cooling circulation method is adopted to solve the problem by additionally arranging a medium pool and a cooling tower, communicating the medium pool with a quenching medium pool through a large-flow pump and a pipeline, and quickly taking away the cooling medium with the temperature raised near the quenching steel piece, cooling and recycling the cooling medium to the medium pool.
With the continuous development of modern industry, the demand of large-size and large-tonnage steel pieces is increasing day by day. Along with the above, the heat treatment quenching method of steel is also diversified, especially, the double-liquid quenching and the staged quenching are normal, and the method not only requires the heat treatment operation workers to have actual operation experience, but also puts strict requirements on heat treatment quenching equipment, wherein scientific and reasonable emphasis is placed on the details of the layout of a double-liquid quenching tank, the path setting of the staged quenching and the like.
In conclusion, the intensive and reasonable arrangement of the circulating cooling system consisting of a plurality of quenching baths, cooling towers, coolers and a plurality of pipelines is an important means for optimizing the quenching process route and improving the quenching quality and efficiency.
