Refractory Materials for Calcining Furnace

Introduction

Through improving the manufacturing technique, continuous dense glaze of SiO2 surface course formed on the surface of brick, keep the erosion from sulfur element in carbon material, better thermal conductivity than silica bricks, used with high temperature abrasion resistant material and one layer hard ceramic glaze can be formed under high temperature, having thermal radiation capacity, efficiently reflex the infrared heat in furnace chamber to increase the heat conducting, make the petrol coke burning fast and fully to save the fuel consumption.

Features:
1: High mechanical performance, good anti-abrasion with dense structure
2: High modulus of rupture at high temperature
3: Good thermal shock resistance
4: Anti-stripping and anti-erosion
