What is a firebrick：

In simple terms, refractory brick is a kind of brick that can withstand combustion and high temperature, its refractoriness is about 1700°, and it is usually made of refractory raw materials by batching, forming and roasting. Refractory brick according to the use of raw materials can be made of different uses of refractory brick, according to the use of parts can be made of different shapes of refractory brick.

Refractory materials are generally divided into two types, that is, amorphous refractory materials and shaped refractory materials. Amorphous refractory material is also called castable, is composed of a variety of aggregates or aggregates and one or more adhesive mixtures of mixed powder particles, must be used with one or more liquids mixed evenly, with strong fluidity. Shaped refractories generally refer to refractory bricks, whose shape has standard rules, and can also be temporarily processed when cutting as needed.

What are the uses of firebricks：

1, refractory brick is not less than 1750°C of inorganic non-metallic products, suitable for a variety of high temperature kiln masonry lining use, its main role is to protect the furnace shell steel structure is not melted by high temperature.

2. Refractory bricks have long been used in the ceramic industry to build fire kilns.

3, because of excellent fire resistance, it has also been used in industrial and home life. Many people build villas using firebricks, which can greatly improve fire performance

4, the most common application of firebrick is in a variety of thermal equipment and high temperature containers, as a structural material and lining resistant to high temperature.

5, in the iron and steel industry, coke ovens are mainly composed of refractory materials. The blast furnace and hot blast furnace of ironmaking, all kinds of steelmaking furnaces, soaking furnaces, heating furnaces and so on are indispensable to meet the requirements of various refractories.

Note that different varieties of refractory bricks can not be mixed, in the construction of refractory bricks, the same variety of refractory mud should be used as the bonding material.
