Improvement study of quality control in process of producing flux-cored wire

Abstract

The flux-cored wire is a new kind of welding material with many advantages. The quality and uniformity of flux-cored wire are affected by its production mode greatly. In this paper, the cause of uneven quality flux-cored wire produced under steel rolling process is investigated firstly. Then, a mathematical model of relative motion between the rolling machine and the strip is carried out based on the principle of reverse engineering. After that, some reasonable design conditions for control systems and production equipment are obtained by solving the model. Finally, an example for the actual production is introduced for verification.
