A Guide To Refractories Firebricks

October, 14, 2013

Today, Firebricks have an extensive usage in several industries like iron & steel, chemical, construction, and many others. Firebricks are, basically, special kind of bricks that can easily withstand different temperature ranges and can bear repeated cooling and heating. Owing to the excellent structural and insulating qualities, Firebricks are best suited for building heat and flame prone areas like burner pots, chimneys, fireboxes, kilns, etc.

Firebricks-An overview

You can choose from two types of Firebricks, hard bricks and soft bricks. Hardbricks are an important material for building chimneys, burner pots, fireboxes, large kilns, etc. Because of their high density, durability and structural qualities, they are suitable for use around direct flame. Softbricks, on the other hand, are used for constructing insulating liners in reduction kilns or electric kilns. The Softbricks are also called insulating firebricks (IFBs). These lightweight bricks are made up of refractory clay that contains combustible materials.

Firebricks are majorly made up of alumina and silica, which makes them resistant to high temperatures. As per the specific use, these Firebricks can be chosen from the long list of grades that vary according to their composition and properties. These Firebricks are graded into:

  1. Low-duty Firebricks
  2. Medium duty Firebricks
  3. High Duty (first-quality firebrick) Firebricks
  4. Super Duty Firebricks
  5. High-Fired Super Duty Firebricks

Most of the Firebricks are either pressed or extruded. The brick mix is air hammered into wooden or steel molds for making bigger pieces as per the desired dimensions and shapes. Some of the most common shapes of Firebricks are:

  1. Straights
  2. Square edge tile
  3. Soaps
  4. Splits
  5. Arch
  6. Wedge
  7. Skew
