Primetals Technologies will supply the complete mechanical equipment along with full Level 1 and Level 2 automation systems. The customer’s positive experiences with long casting machines from Primetals Technologies coupled with a strong portfolio of similar references were the two main factors influencing the choice of supplier.

The caster will enable the production of high-quality blooms for export markets, focusing on premium rails and wire rod, including steel cord used for tire reinforcement. It will feature the largest curved copper tube mold ever implemented by Primetals Technologies, ensuring cost-effective production of high-value-added, high-quality thick blooms. The DynaFlex hydraulic oscillator, which allows for flexible adjustment of the mold-oscillation parameters, is another key mechanical feature, resulting in improved strand-surface quality.

Advanced automation systems make sure the casting machine is optimized for both current and future needs. The fully automated roll-gap control system “Dyna Gap Soft Reduction” minimizes centerline segregation, enhancing internal strand quality. The bloom caster will also be equipped with “Dynacs 3D”, a secondary-cooling model that calculates the full 3D temperature profile along the entire strand, facilitating optimal adjustments of secondary-cooling setpoints. Mold level stability will be controlled by the automatic “Lev Con” control system, which includes autostart casting functions and auto-adaptive dynamic bulging compensation.

The producer is part of a multinational enterprise group, and the comprehensive product range includes rebar, plate, hot rolled sheet, cold rolled sheet, galvanized sheet, color coated sheet, round steel, profiled steel, wire rod, and steel rails.
