Calcium-free silica bricks are becoming more and more common on the top of glass furnaces, but their appearance is similar to ordinary silica bricks. How to pick it out at a glance? The following three methods can be used directly.…
Want to choose refractory materials for high temperature kiln lining but feel overwhelmed? First focus on zircon fire bricks, and you will understand after reading this for three minutes. 1.What does zircon fire brick contain? First look at the ingredients.…
Zircon bricks are common refractory bricks in high temperature industries. However, many people don’t know where it is used specifically. Therefore, in order to let everyone better understand this brick, this article mainly introduces the common uses of this brick.…
Reverberatory furnaces must withstand the erosion of high-temperature slag and molten metal for extended periods of time, and the lining material directly determines their operating cycle. Magnesia-chrome bricks are a common choice for reverberatory furnace linings due to their balanced…
Glass melting furnace is the core equipment of glass production, and its lining material directly determines the life of the furnace and the quality of glass. Different types of refractory bricks are required for different parts due to different working…
High-temperature industries like steel, nonferrous metals, and cement all rely on refractory bricks. Magnesia-carbon bricks, due to their resistance to corrosion, high temperatures, and spalling, have become the standard for furnace linings. What are the uses of these bricks? This…
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…
