Abstract

The invention relates to an inner wall washer of a steel tube. The washer comprises a track, a rail car, an iron-brush motor, a trolley motor, a steel tube bracket and an iron brush, wherein the rail car runs on the track, the trolley motor is fixed on the rail car, the wheels of the rail car are driven to rotate by the rail car, the iron-brush motor is fixed at the rear part of the rail car, the end part of the output shaft of the iron-brush motor is coaxially provided with the iron brush, a water spraying pipe is mounted at the side of the output shaft and the opening of the water spraying pipe faces to the diametric plane of the iron brush. The invention has the advantages of simple overall structure, scientific and reasonable design, high washing efficiency and perfect washing effect, and can be used for effectively cleaning the graphite adhered to the surface of the inner wall of the steel tube after the process of thermal diffusion so as to reduce the adherence of graphite, which is beneficial to acid washing of steel tube, thereby improving the subsequent processing quality of steel tube.

Description

technical field [0001] The invention belongs to the field of steel pipes and relates to cleaning of steel pipes, in particular to a steel pipe inner wall cleaning machine. Background technique [0002] In the thermal expansion process of steel pipes, it is necessary to use graphite as a thermal expansion lubricant for steel pipes at high temperatures. When the thermal expansion process is over, graphite needs to be cleaned from the inner wall of the steel pipe to avoid the residual graphite on the inner wall surface of the steel pipe in the subsequent cold drawing process from scratching the inner wall surface of the steel pipe, thereby affecting the surface quality of the inner wall of the steel pipe, and further affecting the use of customers . In response to this problem, the previous treatment method was to pickle the inner wall of the steel pipe and soak it in the acid solution for 1-2 days to remove graphite. However, pickling has no obvious cleaning effect on the gr...
