Zero Thermal Expansion Silica Brick

Zero thermal expansion silica brick is also known as fused-quartz brick or thermal shock resistance silica brick. The main raw materials are amorphous fused silica and the thermal expansion coefficient is near zero, so the product is named zero thermal expansion silica brick.

Advantages:

1. Longer service life, accurate size tolerance, pure color, luster appearance.

2. Excellent thermal shock resistance.

3. Good structural strength at high temperature.

4. Zero thermal expansion rate

5. Without crack and peeling phenomena.

Application:

1. It is widely used in hot repair project on coke oven.

2. Coke oven maintenance time shortens greatly. Ensure the quality of coke oven repair. Improve the production of coke oven.

3. CUNSE is not only providing the hot repair method of coke oven, but also contracting for coke oven maintenance.
