An efficient solution to the manufacture of tubular products lies in the use of continously cast round billets, as they present lower costs and satisfactory quality. The study analyzes the factors that determine high performance results of this solution: quality of liquid steel, technological level of the casting system, parameter-optimized automatic control and regultion of the whole process and data monitoring and processing. The research analyzes the technological flow: heating in Eccentric Bottom Tapping (EBT), flux dosing, regulation of chemical and heating conditions, liquid steel treatment in Ladle Furnace (LF), the amount and quality of slag, outputs of Aluminum and Calcium, temperature regulation, steel casting without electromagnetic stirrer (EMS), steel overheating, primary and secondary cooling, improvements of equipment and work parameters.
