Application of Zircon Refractory Brick
Zirconia bricks are used for key parts of glass kilns, steel furnaces, picture tube furnaces, metallurgical furnaces, and other high-temperature industrial furnaces. It can be used for top, bottom and lining of furnaces. Our technicians have abundant experience in zirconia bricks. We have completed lots of cases about different industrial high-temperature equipment.
Advantages of Zircon Refractory Brick
1.Excellent Thermal Shock Resistance: Kerui zirconia refractory can resist thermal shock. In glass kilns, hot air will shock the refractory linings. The refractory bricks may crack or damage. Zirconia refractory can avoid this situation because of the excellent thermal shock resistance. It can effectively extend the life cycle of high-temperature equipment.
2.Good Mechanical Shock Resistance: Zircon refractory bricks can resist mechanical shock resistance because of the high density of the structure. In the production process, equipment will receive various mechanical shocks. They can used for the vulnerable parts of industrial furnaces to prolong the service time.
3.Stable Chemical Structure: Zircon refractory is an acidic refractory brick that can be used for glass kilns. It can resist acidic chemical solutions and slags. In this situation, zircon brick will not affect the production. It is an ideal refractory brick for glass kilns.
4.Low Thermal Conductivity: Zircon bricks have low thermal conductivity. It can sustain high temperatures in industrial equipment. The low thermal conductivity helps improve energy utilization. Moreover, it has good electric insulation that can use electronic materials.
