Frequently Asked Questions (FAQ)
Q1: What is the zirconia content of your slide gate plates?
Our zirconia plates typically contain 70%–95% stabilized ZrO₂, depending on the application.
Q2: Can you manufacture non-standard shapes?
Yes. We support custom dimensions, thicknesses, and geometries based on your ladle slide gate system drawings.
Q3. What is the service life of your zirconia slide gate plate?
Service life varies by steel grade and casting conditions but generally lasts significantly longer than alumina-carbon plates.
Q4: What other refractory products do you supply for steelmaking?
We also manufacture Ladle Nozzles, Well Blocks, Purging Plugs, and Seat Bricks, forming a complete steelmaking refractory system.
Q5: How does Xintai ensure product quality?
We have a strict quality management system (ISO certified), advanced testing equipment, and over 20 years of experience in refractory manufacturing.
