Cause analysis and improvement measures of steel-heaping in wire rods production
Abstract
Based on the composition detection results of steel inclusions, it is found that the steel-heaping reason of cold heading wire is caused by the slag entrapment in steelmaking process. In view of the above reasons, by controlling the fluctuation of liquid level of tundish, controlling the fluctuation of continuous casting speed, optimizing the thickness of covering slag and tundish cover powder, the phenomenon of steel-heaping in the rolling process can be effectively reduced when producing Q195 and other cold heading steel. It is of great significance to guide process improvement.
