Product Introduction
Fused silica brick also known as zero thermal expansion silica brick is a high-precision and high-purity high-grade quartz refractory material.It is a excellent product for coke oven.By using zero thermal expansion silica brick, the maintenance time for coke oven shortens greatly.
Features
1.Low thermal expansion rate. 2.Excellent thermal shock resistance. 3.High SiO2 content.
Application
Fused silica brick is widely used in hot repair project on coke oven.By using zero thermal expansion silica brick, the maintenance time for coke oven shortens greatly.
