(2)Features:
1.High Refractoriness,usually The Refractoriness Is Above 2000°C.
2.Refractoriness Under Load About 1500-1550°C Because Of Poor High-temperature Intensity.
3.Strong Ability To Resist Basic (alkaline) Slag,can Not Contact With Acid Refractory Material.
4.Poor Thermal Shock Resistance,so Keep The Temperature Of Furnace Stabilized.
5.Poor Volume Stability At High Temperature,must Set Aside Appropriate Expansion Joint When Laying Brick.
6.Strong Ability Of Thermal Conductivity,sometime Need Insulating Material.
7.Hydrability, Keep Product Away From Moisture During Storage.
(3)Applications:
1.Iron Steel Industry:furnace, Metal Mixer Furnace Lining, Converter Lining, Arc Furnace Wall And Furnace Bottom, Soaking Furnace, Heating Furnace Bottom,
Non-ferrous Metallurgical Industry:copper,nickel,lead,zinc,tin Smelting Furnace Lining, Refined Copper Reverberatory Furnace,ore Electric Furnace Lining
3.Glass Industry:glass Furnace Regenerator Checker
4.Building Material Industry: Lime Kiln,cement Kiln
5.Refractory Material Industry: High Temperature Calcination Kiln,shaft Kiln And Tunnel Kiln
