Refractory materials play a crucial role in various high-temperature industrial applications. They are used to protect equipment inside furnaces from the harsh effects of high temperatures, chemical corrosion, and mechanical stress. When it comes to selecting refractory materials, people often face a significant question: What is the difference between Firebrick and Insulating Fire Brick?

With the increasing frequency of use of refractory materials in various industries in recent years, companies have begun to tackle key technical problems and carefully control them. At present, the most difficult difficulty to overcome is the safety of the insulating fire brick, which is its service life. The following are the process management measures taken by our company to prolong the life of the insulating fire brick.

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.

With the development of social economy, people put forward higher requirements for refractories. Therefore, the refractory industry, which relies on extensive economic growth for a long time, should be adjusted to meet the needs of the new situation. However, before adjusting, we should fully understand the products of insulating fire brick in order to better tap their value. Next, by comparing with ordinary bricks, we can let more people understand the advantages of insulating refractory bricks, so as to better develop them.
