What is magnesium-zirconium flow liquid hole cover plate brick?
magnesia–zirconia refractory bricks
The magnesium-zirconium flow liquid hole cover plate brick is made by magnesium-zirconium refractory material and is a key Block used to cover and protect the flow liquid hole of the glass kiln.
Main parameter:
·High temperature: used for a long time at temperatures above 1500 °C
·Chemical erosion: Subjected to continuous and high-speed erosion and penetration by the highly alkaline molten glass liquid.
Temperature fluctuation: Under conditions of kiln cooling, heating, or unstable working conditions, it will endure thermal shock.
·Mechanical stress: Experiencing pressure from the upper kiln structure and the flow stress of the glass liquid.
·Gas phase erosion: The alkali vapor (R₂O) in the kiln atmosphere will condense and erode the bricks.
Magnesium-zirconium bricks, due to their unique properties, have become the preferred or essential materials for modern high-performance glass kilns, especially for non-alkaline glass, electronic glass, and high-alkaline bottle and canning glass kilns.
