In the world of kiln operation, few phrases are more frustrating than “frequent lining replacement.” It represents not only repeated material costs, but also production downtime, rising energy consumption, overloaded maintenance teams, and silent loss of capacity. For many operators, this cycle has become routine. … Read More
AZS refractory materials (Al₂O₃–ZrO₂–SiO₂) are core lining materials for glass furnaces. Different AZS brick grades show significant performance differences in corrosion resistance, glass contamination control, and service life. Correct selection of AZS 33, AZS 36, and AZS 41 for specific furnace zones directly affects furnace … Read More
Industrial refractory lining is not a simple combination of materials, but a system-level engineering solution driven by functional requirements. In modern furnace lining and kiln lining design, structural configuration, material selection, and performance verification must be accurately matched to real operating conditions. 1. Structure Analysis: … Read More
Refractory Gunning Material vs. Trowelling Castable — How to Choose Precisely? In the construction and maintenance of industrial furnaces and high-temperature equipment, fast and reliable lining installation is essential. Moreover, besides traditional fire bricks, monolithic refractories have become widely used because they provide greater flexibility, … Read More
Selecting the correct refractory material is one of the most important decisions in furnace construction and maintenance. Two of the most commonly used materials—insulating castable and dense castable—serve very different roles. Choosing the wrong one can result in heat loss, higher fuel consumption, premature lining … Read More
Essential Preparation for Refractory Cement Projects Successful refractory work begins with careful preparation. First, select the cement grade that matches your maximum operating temperature and thermal cycling requirements. Gather all necessary tools, including clean mixing containers, calibrated scales, trowels, and personal protective equipment. In addition, … Read More
Surface Preparation Fundamentals Proper surface preparation ensures optimal refractory cement adhesion and performance. First, thoroughly clean the substrate, removing all dust, oil, and loose particles. For metal surfaces, remove rust using grinding or sandblasting. For existing refractory surfaces, chip away damaged material and create a … Read More
