The zirconium spout produced by our company has regular appearance, high concentricity, good thermal shock stability and excellent scour resistance, which can fully meet the billet continuous casting. In order to suit the development of continuous casting technology, we have developed and produced zirconium composite quick-change system, which has been well applied at home and abroad; the zirconium cores produced can be used to provide supporting facilities for the production of quick-change spouts by other sister manufacturers.
