Automatic Settlement System of Liquid Steel Level Into the Tundish for Continuous Casting Machine
MetadataShow full item record
The increasing quality of steel and a reliability indices of the afferent installations need an automation system for continuous steel casting machines. This paper presents an original solution of automatic settlement of liquid steel debit and level in tundish as well as an analysis of the dynamic behaviour of automatic installation. The results of continuous casting timing satisfy quite all the quality conditions of technological operations: the level variation stands in admissible limits while the records of the level allow the control of installation functions. During all the experiments, the automatic settlement was stable and reliable. The realization of automatic settlement system of liquid steel level in tundish is important for the continuous casting slab quality (under the purity aspect of nonmetalic inclusions) as well as the surface defects avoidance, with efects over productivity of continuous casting machines and cost reduction.
