Talking about the Requirement of Using Refractory Material in Boiler 's Refractory Belt

The main properties of refractory material in the boiler shall include slag resistance, high strength, wear resistance, thermal stability and high thermal conductivity. The traditional fire-burning refractory material Ladle Permeable Brick mainly uses chrome ramming material. Due to the shortage of domestic high-quality chrome resources, the main use of silicon carbide ramming material, silicon carbide high aluminum coating material, high aluminum phosphate plastic, high temperature Expandable plastic.

The first two kinds of materials, the price is higher, but long life, good performance, while the latter two materials, although the price is low, but the performance in general, and short life. For this reason, it is not advisable to use high phosphate refractory ladle slide gate plastic or ramming compound in the cyclone furnace and the liquid slag discharging furnace to avoid the occurrence of peeling or cracking in use, so as to enhance the slag resistance of the material and reduce the repair frequency.

High-temperature micro-expansion of fire-resistant plastic and super-3000 fire-resistant water clay quite the same performance, used in the wall through the boiler and boiler roof to show a certain advantage. However, this material itself, a longer solidification clay insulating bricks time, prone to shrinkage cracks, which for the construction and maintenance of a lot of trouble. At the same time there is a certain quality of supply volatility, and sometimes the refractoriness and strength at room temperature less than 1580 degrees and 981N / cm2.

Refractory company Henan Xinmi Changxing Refractory Material Co., Ltd. Located in Henan Province,China.ChangXing's product portfolio covers shaped products such as refractory materials,refractory brick, refractory castable,refractory nozzle, ceramic fiber, slide gate, etc; unshaped products including repair, construction and casting mixes and mortars.exported to more than 20 countries, such as Thailand, Indonesia, Pakistan, Saudi Arabia, South Africa, Turkey, Iran, Iraq and so on.
