The invention discloses a seamless stainless steel tube purging device and method. The device comprises a high-pressure sand water pot portion, a pipeline portion, a stainless steel tube moving worktable portion, a structure support and sand water recycling and cyclic utilization portion and an electrical control portion. A sand water gas flow purging method is adopted for improving the degreasingquality of a seamless stainless steel tube after cold rolling, in the purging process, an earlier-period sand water purging and later-period gas blowing cleaning process is adopted in the purging process, in the earlier-period sand water purging process, a high-pressure high-speed rotating sand water gas flow is adopted for strong purging of the stainless steel tube, and in the later period, high-pressure high-speed rotary gas flow is adopted for strong cleaning of the stainless steel tube. The problems of scale breaking or pretreatment difficulty and incomplete stainless steel tube inner degreasing, unstable degreasing quality, and relatively hard and difficultly-cleaned attached impurities can be solved, and the stainless steel pipe manufacturing quality is improved.
Description
technical field [0001] The invention relates to a purging device and method for a seamless stainless steel pipe, belonging to the technical field of stainless steel pipe forming engineering. Background technique [0002] During the rolling and forming process of stainless steel pipes, the process of degreasing, heat treatment, straightening, with or without pickling and passivation (determined by the heat treatment process with or without pickling process) after cold rolling of seamless stainless steel pipes often has clean quality in the stainless steel pipes. If the requirements are not met, the main manifestations are: although the degreasing time is about 4 hours, there are still incomplete degreasing inside the stainless steel tube, and the degreasing quality is unstable. At the same time, there are relatively hard grease and dust attached to the inside of the stainless steel tube. and metal particles and other sundries, resulting in uneven oxide scale in the heat treat...
