Description

Technical Field

[0001] The utility model relates to the technical field related to a solid solution treatment cooling device, in particular to a cooling device and a duplex stainless steel solid solution treatment device. Background Art

[0002] The solution treatment cooling device makes the steel pipe structure and composition uniform, which is especially important for raw materials. Because the rolling temperature and cooling rate of each section of the hot-rolled wire are different, resulting in inconsistent structure, atomic activity intensifies at high temperature, σ phase dissolves, and the chemical composition tends to be uniform. After rapid cooling, a uniform single-phase structure is obtained, eliminating work hardening, which is conducive to continued cold processing. Through solution treatment, the distorted lattice is restored, the elongated and broken grains are recrystallized, the internal stress is eliminated, the tensile strength of the steel pipe is reduced, the elongation is increased, and the inherent corrosion resistance of stainless steel is restored. Due to the precipitation of carbides and lattice defects caused by cold processing, the corrosion resistance of stainless steel is reduced. After solution treatment, the corrosion resistance of the steel pipe is restored to the best state.

[0003] When the existing solution treatment cooling device is used to treat duplex stainless steel, it is necessary to manually place it in the solution treatment box repeatedly. During the repeated placement, cooling and drying are required, which leads to uneven rapid cooling, causing work hardening and is not conducive to further cold processing. Utility Model Content

Therefore, when the solution treatment cooling device is used to treat duplex stainless steel, it does not need to be manually placed in the solution treatment box repeatedly. It can be hydraulically pushed by the hydraulic cylinder 8 and the lifting rod 7 to avoid direct contact between the staff and the duplex stainless steel.
