Description

Technical Field

[0001] The utility model belongs to the technical field of cooling devices, and particularly relates to a steel pipe cooling device. Background Technique

[0002] The rapid cooling treatment of steel pipes is a method of strengthening steel pipes by using the quenching process. After the red-hot steel pipes are subjected to rapid cooling treatment, a layer with higher hardness will be formed on the surface, thereby increasing the strength and wear resistance of the steel pipes. The basic principle of the rapid cooling treatment of steel pipes is to quickly cool the steel pipes to reach a metastable state through rapid cooling, so as to form a change in the cooling tissue structure and achieve the purpose of strengthening. The water cooling method is one of the most commonly used methods for the rapid cooling treatment of steel pipes. The specific operation steps are to quickly put the red-hot steel pipes into water to quickly cool the surface of the steel pipes. It should be noted that when using the water cooling method, the water temperature should be about 5°C to avoid using overly cold water that will have a negative impact on the mechanical properties of the steel pipes.
