High Temperature Silica Bricks For Hot Blast Furnace Customized Sizes
Description

High temperature silica bricks are a type of refractory brick commonly used in hot blast furnaces. These bricks are made of high purity silica, which has a high melting point and excellent thermal conductivity. They are able to withstand extremely high temperatures and thermal shock, making them ideal for use in the harsh environment of a hot blast furnace.

The properties of high temperature silica bricks make them ideal for use in hot blast furnaces. They have a high melting point, low thermal expansion, and excellent thermal shock resistance. They also have good chemical resistance to the gases produced during the combustion process. In addition, silica bricks are relatively inexpensive and easy to manufacture.
