Brick
Cer-Met, Inc. is a distributor of all
types of brick used in the refractory industry.
Often used in high temperature applications, firebrick can be used as a
lining or as a backup to monolithic refractories. Throughout the refractory industry there are
several types of brick which fall under four main classes. The four main
classes of brick can be classified as Basic, Fireclay, High Alumina and Silica. Insulating Firebrick (IFB) are lightweight, high temperature brick with excellent thermal shock resistance properties.
Basic
Basic refractory brick are used to provide resistance to corrosive reactions and fluxing agents such as iron oxide. Several types of brick fall under the basic class with main raw materials consisting of magnesites, dolomite, chrome and carbon.
Fireclay
Fireclay refractory brick are the most popular brick used in refractory applications. The four standard classes are composed of low-duty, medium duty, high duty, super duty. Used throughout the industry, fireclay brick have good strength properties along with low thermal conductivity and resistance to thermal shock and abrasion.
High Alumina
The High Alumina refractory brick is classified directly to the proportion of alumina content. These bricks are selected due to several features that differentiate them from other classes of brick. The main selection for High Alumina brick comes from its use in extremely high temperatures. However, resistance to abrasion, spalling, and corrosion along with high strength also led to the selection of High Alumina Firebrick.
Silica
Silica fire brick has a high refractoriness that allows the brick to perform at high temperatures with great strength properties. Silica brick are also essential free of thermal spalling and have better thermal conductivity properties then fireclay brick.
Insulating Firebrick (IFB)
Insulating Firebrick are lightweight, energy efficient brick with excellent alkali resistance. IFBs are very stable and strong at high temperatures and can be easily cut and shaped. These brick can be used as a backup lining behind firebrick or as a stand alone lining in furnaces and forges.
