Magnesia zirconia Bricks are used in glass kilns

In the glass melting industry, kilns are constantly exposed to high-temperature, highly corrosive slag and furnace gas environments, placing extremely high demands on refractory materials. Magnesia-zircon bricks, due to their excellent corrosion resistance and high-temperature performance, especially their highly efficient alkali resistance, have become one of the key refractory materials for critical components of glass kilns.

Why do magnesia zirconia bricks have excellent alkali resistance?

Magnesia-zirconium bricks are composed of fused magnesia and zircon sand. This combination is key to their excellent alkali resistance. Fused magnesia possesses high refractoriness and good chemical stability, while zircon sand forms a dense structure that effectively resists the penetration of alkaline gases and slag. Even when exposed to the harsh alkaline environment of glass furnaces, this unique composition allows magnesia-zirconium bricks to maintain their integrity and performance.

Advantages of magnesium zirconium bricks

One of the core advantages of magnesia-zirconium bricks is their high density, with a bulk density greater than 3.08 g/cm³. This high density brings several important properties:

Erosion Resistance: The dense structure effectively resists the erosion of alkaline slag, reducing brick wear and extending its service life. Például, in high-alkali glass kilns, traditional bricks are eroded by slag by 5-10 mm per year, while magnesia-zirconium bricks can reduce this erosion rate to less than 2 mm per year.

Sparging Resistance: They have better thermal shock resistance, preventing bricks from sparging under rapid temperature changes. In glass kilns, where temperatures fluctuate frequently during melting and cooling, magnesia-zirconium bricks maintain their structural integrity better than traditional bricks.

High Temperature Resistance: Magnesia-zirconium bricks can withstand temperatures up to 1700℃, ensuring stable operation of high-temperature glass kilns.

Magnesium-zirconium bricks provide a stable, durable, and energy-efficient refractory material solution for alkaline industries, especially glass kilns. Their unique composition, high density, and superior performance help companies reduce costs, improve efficiency, and enhance environmental protection.

Selection of refractory bricks for glass kilns

Traditional refractory materials used in glass kilns often face numerous challenges, such as poor alkali resistance, frequent replacements, and high maintenance costs; gyenge hőkancia -ellenállás, which can easily lead to material spalling and affect the normal operation of the kiln. Magnesia-zirconium bricks can effectively solve these problems. Their excellent alkali resistance reduces the frequency of replacement, and their thermal shock resistance ensures stable operation of the kiln under complex temperature conditions.
