Slidegate Plates for the Toughest Steel Grades

Zircoa’s Own Zirconium Oxide Composition Delivers Longer Operation and Peak Performance

Current tundish and ladle gate refractories cannot, at times, meet the pouring and life requirements for some grades of steel. Zircoa’s Composition 3004, a high quality magnesia stabilized zirconium oxide refractory meets these tougher requirements.

For more detailed information on the unique properties of Zirconium Oxide (A Grain Zirconia, ZrO₂) please visit our Solutions page: www.zircoa.com/solutions, or contact a product specialist to discuss your specific needs.

For New and Existing Systems

Composition 3004, used in Zircoa slidegate plates, is designed to offer superior erosion and corrosion resistance, as well as excellent thermal shock properties. Other steel making refractory components can also enjoy similar performance characteristics, with the addition of Composition 3004 inserts as shown below. Zircoa slidegate plates and Composition 3004 inserts... stand-up to the toughest steel grades and extend refractory component service life at a favorable cost advantage.

Typical Components with Composition 3004 Inserts
