What is a refractory tile?
A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
How much does refractory brick cost?
A typical firebrick measures 9″x4. 5″x2. 5″, weighs about 8 pounds and is yellow. The price of a good quality firebrick is currently around $2.45+ each.
What is refractory brick masonry?
A refractory brick, or fire brick, is a unit made specifically to survive high temperatures and unkind elements. It is commonly utilized in structures that must withstand high levels of heat, such as wood-fired kilns, furnaces and ovens. They are also frequently used in homes as a liner for fireplaces.
What is in refractory bricks?
For domestic uses, such as ovens, barbecue grills and fireplaces, the refractory bricks used are usually composed of clay containing mainly alumina and silica, elements capable of withstanding high temperatures. While alumina has reflective qualities, silica is an excellent insulator.
What is refractory give an example?
Examples of conducting refractories are SiC and ZrC, whereas examples of nonconducting refractories are silica and alumina. Insulating refractories include calcium silicate materials, kaolin, and zirconia. Insulating refractories are used to reduce the rate of heat loss through furnace walls.
Is 8 refractory brick specification?
3.2 The refractories shall be compact, of homogeneous texture and free from cracks, voids and other flaws. They shall be burnt evenly throughout, shall have no soft corners and have sufficient mechanical strength. Type 2 – Suitable for more critical applications.
Where are refractory bricks used?
Refractory bricks (fire brick): A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
What is basic refractory?
Basic refractories are used in areas where slags and atmosphere are basic. They are stable to alkaline materials but can react to acids. The main raw materials belong to the RO group, of which magnesia (MgO) is a common example. Other examples include dolomite and chrome-magnesia.
