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.

​The raw materials used for lightweight insulating fire brick can be classified into clay, silica, aluminum and mullite. Light insulating fire brick's insulation is due to the brick body inside contains a large number of air holes (including closed air holes and open air holes). The method that causes stomata has to add combustible matter law, foam law, chemical law. Insulating fire brick has low compressive strength, poor slag resistance, poor thermal vibration resistance, and can not be in direct contact with liquid glass or flame. The article Introduces a few kinds of common insulating fire brick below.

Insulating fire brick is to have heat insulation effect of building top namely and the heat insulation material of the brick form that lays in building top, it is one of the materials that often uses at heat insulation of building top in a modern building. Insulating fire brick with the regular shape of thermal insulation products. Let's introduce the physical properties of the insulating fire brick.

Insulating fire brick is a kind of thermal insulation product with a regular shape. 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 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.

The selection and collocation of kiln furniture materials are various. In recent years, with the rapid development of China's economy, the kiln furniture industry has also made great progress. High quality kiln furniture with lightweight, thin and diversified specifications have been supplied to the market one after another. There are cordierite, cordierite mullite, mullite, common silicon carbide, oxide bonded silicon carbide and so on. There are many kinds of matching forms of materials, but it also depends on the type of products, kiln structure, bearing capacity and price bearing capacity of the ceramic factory.

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℃.

Kiln furniture has the function of isolating products from each other, so that a single product is not damaged by any external impact. The demand for kiln furniture has increased sharply in recent years. What is the kiln furniture used for? Why should choose kiln furniture? The following article will provide you with some information.

Installing kiln furniture is of great importance during manufacturing processes. Ceramic kiln furniture has the function of keeping products from each other so that individual product will not be damaged by any external impact. The demand for kiln furniture has increased a sharply in recent years. What applications does kiln furniture have? Why should we select kiln furniture? The passage below will provide you with some information.
