Delivering 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 New and Existing Systems
Composition 3004, used in Zircoa slide gate 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 here.
Zircoa slide gate 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
Zircoa’s slide gate plates and Composition 3004 inserts are the best choice for both ladle and tundish gate system components, solving unsatisfactory pouring performance and reducing overall steel making costs.
