Furnace Brick
We deal Fire Clay & High Alumina Bricks. Alumina is an excellent engineering ceramic, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. It is also an electrically insulating material, with a high electrical resistivity, increasing with purity.

High alumina Fire brick, alumina content above 48%, is a kind of aluminosilicate refractories. Bauxite and other raw materials with high aluminum content are calcined and shaped into high alumina bricks. High alumina brick belongs to aluminosilicate refractories. The main mineral composition of such products is aluminum oxide, mullite and corundum. High alumina brick has relatively high physical properties.
High alumina Fire brick, with its refractoriness above 1700โ, have high thermal stability, good slag resistance,high strength, good volume stability, low creep rate etc.
High alumina bricks are widely used in industries of blast furnace, hot blast stove, electric furnace, refining furnace and glass furnace and so on.

A fire brick, firebrick, or refractory brick is a block of refractory 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. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from wood, fluxing from ash or slag, and high temperatures. In other, less harsh situations, such as in an electric or natural gas fired kiln, more porous bricks, commonly known as "kiln bricks" are a better choice. They are weaker, but they are much lighter, easier to form, and insulate far better than dense bricks. In any case, firebricks should not spall, and their strength should hold up well during rapid temperature changes.

Fireclay Bricks or fire bricks are the most widely used refractory bricks because of their great features: low thermal conductivity; good thermal insulation performance; high resistance to thermal shock, abrasion, chemical attack to provide long service life; easy operation and installation; broad usage and applications; and low price, etc. At KT Refractories we offer a comprehensive range of Fireclay brick/fire bricks consisting of 30-55% alumina, all of which exhibit excellent strength. For higher demands we offer a hard fired "Super duty" Fire clay-brick with a very high mechanical strength.
High density, low porosity fire clay brick is our featured product in this category. Due to its low apparent porosity rate, it has great features of strong resistance to erosion, high refractoriness under load, great cold crushing strength, high mechanical strength, etc.

High Alumina Brick Properties
- High Alumina Bricks belong to advanced refractory materials. They have higher refractoriness reaching up to 1750~1790 than fire clay bricks and semi-silica bricks.
- High Alumina Bricks have higher refractoriness under load than fireclay bricks because that high alumina bricks have higher Al2O3 content and low impurities which forming little fusible vitreum body. But because mullite crystal does not form network structure, their refractoriness under load is lower than silica bricks.
- High Alumina Bricks have more Al2O3 content and belong to neutral refractory materials that can resist acid and basic slag erosion. And as they also contain SiO2 content, high alumina brick can better resist acid slag erosion than basic slag erosion.
High Alumina Bricks are mainly used to build blast furnace, hot blast stove, top of electric furnace, air furnace, reverberatory furnace and lining of rotary kiln.
High Alumina Brick is also can be used as checker bricks of heat accumulating type, chock plug for gating system, nozzle brick and so on.
