Title of Invention: A Device for Cleaning Grooves of Rebar Rolling Mill

This innovative technology belongs to the field of metallurgical rolling equipment. During long-term steel rolling, scale, iron filings and debris tend to accumulate inside the grooves of rebar rolling mills, which impairs the dimensional accuracy of finished rebars. This specially designed supporting cleaning device addresses the production pain points including difficult groove cleaning, low efficiency of manual cleaning and incomplete cleaning. Together with the previous two patents concerning guide storage and guide fine adjustment, it forms a complete technical package for rolling mill auxiliary equipment.
