Sponsoring company: Tata Steel The Llanwern Zodiac continuous galvanising line is installing nitrogen knives for controlling Zinc coating thickness. These gas knives blow nitrogen at the strip, at a specific pressure, to remove excess Zinc.
Strip steel runs at a speed of 170 metres per minute, through the gas knife gap of less than 12mm. Precision is key therefore, to avoid strip break conditions which could stop the line. To address the risk, an electromagnetic stabilisation system to minimise lateral movement of the strip within the gas knife gap, has been purchased. This equipment should permit a smaller gas knife gap and increased line speed, without compromising surface quality.
The Research Engineer will: • Evaluate effectiveness of the electromagnetic stabilisation system and determine product dependent minimum safe strip-knife separation; • Investigate the relationship between coating weight across strip width and strip position to inform true strip-knife alignment and an operational assessment technique; • Develop a process to align gas knives to achieve a uniform Zinc coating thickness with minimal strip-knife separation, in a production environment; • Assess differences in wiping behaviour between conventional Zn/Al and Zn/Al/Mg coatings and to make setup recommendations to maintain coating quality; • Work collaboratively with Tata Steel sites in Europe to identify and share best practice.
