Lip Bricks

Quartz lip brick is a refractory material specially used in specific parts of
high-temperature industrial equipment (such as the "lips" of furnace mouths and
kiln mouths). It is mainly made of high-purity quartz sand (SiO2 content ≥
90%) through high-temperature sintering or melting, and may contain a small
amount of mineralizer to enhance performance.
Advantage
1. High temperature resistance: The melting point is as high as 1700°C, which
is suitable for extremely high temperature environments.
2. Thermal shock resistance: Low thermal expansion coefficient, tolerance to
sudden temperature changes, and reduced risk of cracking.
3. Corrosion resistance: Strong resistance to acidic slag and gas erosion, but
alkaline environment should be avoided.
4. High mechanical strength: Wear-resistant and impact-resistant, suitable for
parts susceptible to mechanical stress.
Application Fields
1. Glass industry: used in key parts such as melting furnace feeding port and
liquid flow hole to withstand the erosion of glass liquid.
2. Metallurgical industry: furnace door, steel outlet and other high
temperature and vulnerable areas.
3. Ceramics and chemical industry: kiln mouth and high temperature reaction
vessel lining.
