At the end of 2016 US Steel entrusted Danieli to replace the stopper-rod control system together with the mould-level control sensors and automation at its Great Lakes Works and Gary Works. Both plants, which operate one double-strand slab caster and two single-strand slab casters (A-Line and B-Line), improved the casting process stability after the installation of the advanced Danieli technologies: HY-POWER® electrohydraulic stopper actuator to regulate the steel flow, eddy-current double-coil sensor for a precise measurement of the mould level, and Q-Level+ automation package for a fine control of the entire system.
Reliability and performance achieved by the newly installed systems helped to achieve the required strip quality goals. Minimum shutdown time and a non-invasive installation proved the practical and beneficial effects of this revamping method. USS confirmed once again its trust in Danieli, deciding to convert the C Line caster at the Gary Works to the same flow technology. This will bring to six the total number of the US Steel casting strands equipped with the Danieli systems.
