Although the use of monolithic refractories has been for many years, it has not been generally accepted in the industry until the 1960s. Refractory aggregate, fine powder and binder (or additive) according to the use of the formula by the appropriate proportion of the mixture to form a monolithic refractory, can be used directly or can be added to the appropriate amount of liquid for use. In terms of transportation, monolithic refractories usually in the form of bulk materials, and then according to the use of the site requirements of different construction methods.

Monolithic refractories by a certain size grading refractory aggregate and powder, binder, admixtures and become refractory materials, also known as scattered refractory materials. Monolithic refractories are used for the lining of thermal equipment. They can be baked directly without firing. Compared with firebrick, monolithic refractories have a simple process (because of eliminating the burning process), energy saving, low cost, easy to mechanized construction and other characteristics, in some thermal equipment to use the effect is better than firebrick.

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.

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.

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.

​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.

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
