What is the Name of Refractory Bricks?

Refractory bricks are also called fire bricks. They are a kind of shaped refractory material indispensable in high-temperature environments. They have the characteristics of high-temperature resistance, creep resistance, earthquake resistance, and corrosion resistance. They can resist high-temperature erosion and medium corrosion, so they are often used for lining high-temperature equipment and furnaces, such as aluminum melting furnaces, blast furnaces, trolley furnaces, glass kilns, etc. They are widely used in metallurgy, construction, chemical industry, power, and other industries. The reason why refractory bricks are also called fire bricks is because they have very high refractoriness. The refractory temperature of some common refractory bricks can reach 1790℃, and the refractory temperature of some high-quality refractory bricks can even reach about 2000℃, such magnesium bricks and corundum bricks. It is precisely because of its excellent refractory temperature that it is widely used in high-temperature industries to ensure the stability of the working environment of smelting furnaces in high-temperature industries and provide stable assistance for the development of high-temperature industries. At the same time, its development is also the key to restricting the development of high-temperature industries. The higher the refractory temperature, the higher the melting point of high-temperature industries. Only in this way...

The Role of Honeycomb Heat Storage Body

Honeycomb heat storage body is an efficient and environmentally friendly heat storage material. Its main role is to recycle and utilize industrial waste heat and waste heat, thereby improving the utilization rate of energy. The structure of the honeycomb heat storage body is similar to a honeycomb, consisting of many small cells, each of which is filled with heat storage materials. When heat passes through the honeycomb heat storage body, the heat storage material absorbs the heat and stores it. When heat is needed, such as heating or power generation, the honeycomb heat storage body can release the stored heat. Therefore, the role of the honeycomb heat storage body is equivalent to an energy storage device. Its appearance has greatly reduced the emission of industrial waste heat and waste heat, reduced energy waste, and also reduced the burden on the environment. In addition, the honeycomb heat storage body also has a high thermal efficiency. Due to its special structure, the honeycomb heat storage body can quickly absorb and release heat. This rapid heat transfer process helps to improve the operating efficiency of the equipment and reduce energy waste. In general, the role of the honeycomb heat storage body is to...
