In industrial projects involving corrosion and high temperatures, two materials are often confused: acid resistant bricks (acid proof bricks) and acid refractory bricks used in acidic environments. Although they may seem similar, these two products are designed for completely different working conditions and are not … Read More
Neutral refractory materials play a key role in industrial furnace linings because they maintain chemical stability in both acidic and basic environments. Unlike strictly acidic or basic refractories, these materials adapt well to complex or changing furnace conditions, making them widely used in industries such … Read More
Acidic refractory materials are designed to perform in environments where acidic slags (SiO₂-rich) dominate and basic components such as CaO or MgO are limited. These materials provide excellent chemical stability and high-temperature resistance, making them widely used in glass furnaces, coke ovens, ceramic kilns, and … Read More
Basic refractory materials play an essential role in high-temperature industrial processes, particularly in environments containing alkaline slags and aggressive chemical reactions. These materials offer excellent resistance to basic slags and maintain stability at extreme temperatures, making them widely used in industries such as steelmaking, non-ferrous … Read More
When it comes to high-temperature insulation, selecting the right material is crucial for efficiency, safety, and cost-effectiveness. Two widely used fabrics in industrial applications are ceramic fiber cloth and glass fiber cloth. Understanding their differences helps engineers and plant managers choose the most suitable insulation … Read More
In the refractory industry, manufacturers usually classify high alumina bricks by their Al₂O₃ content, with common grades including 55%, 65%, and 75%. Many buyers assume that a higher alumina percentage automatically means better performance. In reality, experienced furnace engineers evaluate much more than numbers. The … Read More
High alumina brick is one of the most widely used refractory bricks in industrial furnaces. From steel ladles to cement kilns, from glass furnaces to heat-treatment equipment, it remains a core material in high-temperature lining systems. However, selecting high alumina bricks is not simply about … Read More
Don’t Just Compare Prices — 3 Critical Factors That Determine 20+ Years of Service Life In chemical plants, electroplating workshops, pickling lines, or laboratory projects, the first question buyers usually ask is: “How much does acid resistant brick cost per square meter?” At Kerui Refractory, … Read More
Stop Judging by “White” and “Numbers” From an engineering perspective, Kerui Refractory frequently encounters these misconceptions when assisting customers with high alumina brick selection across steel, cement, and non-ferrous industries.In refractory purchasing, many buyers fall into the same trap: over-focusing on a few visible or … Read More
In practical furnace operation, refractory materials are not selected by name, but by material system, working temperature, corrosion environment, and mechanical load. Below, refractory products are grouped by material category, with international brand names listed inside each category, showing how different names often refer to … Read More
