Description

Basic Brick are high magnesia made primarily from periclase, formed by high temperature firing of synthetic magnesium hydroxide or natural magnesium carbonates.

Heavy duty firebrick comes in Alumina-Silica and High Alumina types, offering stability and high density with good chemical and atmosphere resistance.

Insulating Firebrick, also of Alumina-Silica and High Alumina type compositions, is lightweight and lower density with a higher percentage of air bubbles dispersed throughout the brick.

Application

Basic bricks are used in applications where their greater resistance to fluxing agents, such as iron oxides and alkalies, are needed.

Various grades of heavy-duty firebrick are available for applications where there is a corrosive environment or to provide structural strength and support to a furnace's cold face.

Insulating Firebrick (IFB), produced for service up to 3250°F, offers unsurpassed performance in a wide variety of markets requiring structural insulation. Included are industries as diverse as ceramic ware hobby kiln manufacturers and primary aluminum producers. Common markets for these brick are:

  • New Furnace and kiln builders
  • Aluminum Electrolytic pot cells
  • Carbon anode baking pits
  • Blast furnace stoves
  • Steel reheat furnaces
  • Petrochemical heaters
  • Technical ceramic kilns

Features and Benefits

Heavy-duty firebrick offer marked resistance to spalling, exceptional load carrying capacity at high temperatures, and maintain the ability to withstand chemical attack and high heat conditions.

Insulating firebrick offer lower heat conductivity plus the ability to withstand chemical attack and high heat conditions without weakening. They conduct less heat away from its work within a furnace, and exhibit lower heat storage, heating quickly and economically to the operating temperature and cooling fast to speed turnarounds.
