The blast furnace is the core equipment for steelmaking, and its refractory lining directly determines the lifespan and operating efficiency of the furnace. The function, type, and selection criteria of these materials are all important considerations. 1.Material type and function…
Kiln hole formation is a common fault in industrial production, directly affecting production efficiency and safety. Often, the root cause is not the kiln structure itself, but the improper selection or use of refractory bricks. The truth behind the material…
Ceramic fiber blanket is a thermal insulation material made mainly of ceramic fiber. It is widely used in high-temperature applications due to its excellent high-temperature resistance and low thermal conductivity. 1.Ceramic fiber blanket material composition and basic properties Ceramic fiber…
As a key refractory material for high-temperature zones in industrial furnaces, the performance stability of calcium-free silica bricks directly depends on the core processes in the production process. Among these processes, the selection and addition of binders and the control…
In the glass production process, the performance of the kiln lining material directly affects production efficiency and product quality. As an important refractory material, zirconia 20 bricks play a key role in the glass industry. 1.Zirconia 20 brick material characteristics…
Kilns are the “heart” of high-temperature industries like steel, cement, and glass. Their lining materials directly determine their lifespan and production efficiency. Ordinary refractories are often vulnerable to molten environments exceeding 1600°C, chemical attack, and mechanical erosion. Magnesia carbon bricks,…
In the high-temperature industrial sector, specialty kilns are core production equipment, and their lining materials directly determine their operating efficiency, service life, and production safety. Corundum bricks, as advanced refractory materials with alumina (Al₂O₃) as their primary crystalline phase, are…
In high-temperature industrial applications, refractory materials are crucial for the safe operation of equipment. Silica bricks are widely used due to their excellent high-temperature performance. However, in recent years, a counterintuitive material—calcium-free silica bricks—has emerged as a promising alternative to…
Zircon bricks, as a special refractory material, have been widely used in high temperature industry and chemical fields due to their excellent physical and chemical properties. 1. Basic Concepts of Zircon Bricks Zircon bricks are refractory bricks made primarily from…
Thermal shock is a serious issue during kiln operation. It not only severely impacts the kiln’s service life but can also lead to production halts and financial losses. So, how can this issue be effectively addressed? The answer may lie…
