There are many types of insulating fire bricks. When choosing insulating fire bricks in industrial kilns, it is necessary to choose the appropriate ones according to the actual use temperature inside the kiln, the use conditions of insulating fire bricks, the use cycle and other aspects. This article will introduce the main applications of insulating fire bricks.

Insulating fire brick is a kind of insulating products with a regular shape. It belongs to light insulation refractory material. The common characteristics of this kind of material are small volume density, light bulk density, low thermal conductivity. But the intensity is low, high temperature reburning shrinkage is larger, heat insulation, good moisturizing effect. Refractory brick, also known as firebrick, is made of heat-resistant ceramic materials, similar in shape to ordinary building bricks, so they are often used in building kilns and a variety of thermal equipment. Firebrick won't have chemical change below high temperature on one hand, also be the material with poorer heat conduction commonly. Let's talk about the difference between insulating fire brick and refractory brick.

Refractory brick, also known as firebrick, is a type of brick that is designed or manufactured to cope with high temperature environments. Such bricks are used in kilns and furnaces, for example. Many manufacturers around the world produce refractory bricks of different sizes, shapes and styles. Mos

We all know that refractory brick is made of special material. Ordinary bricks can’t withstand very high temperatures, so it is necessary to use this material with high strength and high temperature resistance as the masonry of various industrial furnaces. In industrial production, almost all high-temperature furnaces need to use refractory bricks, such as glass works, ironmaking, steelmaking, refining furnaces and so on. The following will introduce the specific use of different types of refractory brick.

China's refractory brick production process: crushing - mixing - molding - burning - packaging - delivery. It is a kind of neutral refractory material, by bauxite or other high oxide content of raw materials by molding and calcination. High thermal shock stability, refractoriness above 1770℃. Good slag resistance. Refractory brick is mainly used for the lining of electric steel-making furnaces, glass furnaces and cement rotary furnaces. When the content of Al2O3 in the brick exceeds 71.8%, the excess Al2O3 forms corundum crystal at high temperature and generates two high-temperature crystal phases at the same time. The eutectic temperature of the brick with low Al2O3 content rises from 1595℃ to 1840℃.

From the point of view of development and growth rate, China's refractory industry has farewell to the period of rapid development, and the development mode is transiting to the stage of industrial transformation and upgrading. In the past, purely pursuing the extensive growth of production capacity has no longer adapted to the development trend of the market. At present, the refractory industry is facing a serious imbalance between supply and demand, showing a situation of oversupply. Therefore, the emergence of refractory bricks has greatly alleviated this situation. So, I don't know what you know about firebricks? Here we briefly introduce insulating refractory bricks and related knowledge. Hope to help you better understand insulating refractory bricks.
