Insulating & Dense Castables
The unique aggregate used in BNZ Insulating Castables allows for the formulation of especially low density, thermally efficient products unsurpassed by other products.
A general purpose lightweight castable for use as an exposed hot face refractory or as a very thermally efficient back-up to a dense refractory lining. Can be installed by casting, gunning or slap-troweling.
A lightweight, general purpose insulating castable. Can be used for back-up or exposed to furnace conditions. Used for one-shot linings, petrochemical heaters, combustion chambers and furnace doors and covers. Frequently used in those areas that would require a 2300°F (1260°C) Insulating Fire Brick.
Blazelite 2300 LI and Blazelite 2300 VLI
Similar to Blazelite 2300 but suitable for those applications where reducing conditions might be encountered. These high purity, low iron products are specifically designed for both back-up and exposed to furnace combustion conditions.
An extremely strong insulating castable designed for general purpose use in those areas that require this combination of light weight and high strength, such as forge furnace doors and roofs, reheat furnace sub-hearths, petrochemical stills and heater linings, metal heating furnace hearths, cat-cracking units, reactor vessels, flue and duct linings and kiln car tops.
Blazelite 2600 LI
A low iron, high purity castable for service to 2600°F (1427°C) in controlled atmosphere applications. Recommended for casting monolithic shapes and furnace linings.
Blazelite 2000 G
Widely used for stack linings, heaters and vessels where a gunning mix with low rebound loss is required.
Blazecrete 3000 G
High alumina castable for service to 3000°F (1667°C). Used in building new and repairing old refractory linings, for gunning
Blazecrete 2300 ARG
An alumina-silica castable with high strength and abrasion resistance. For service to 2300°F (1260°C). May be gunned or slap-troweled over Blazelite 2000G to obtain a high strength hot face with a good insulating back-up. Suitable for ash pits, dust collector flues and other areas where abrasive or erosive conditions exist.
A high alumina castable for service to 3200°F (1778°C). It has good volume stability, extremely high modulus of rupture and crushing strength, and is of high purity for special furnace atmospheres. Designed for use in casting burner blocks, roof centers in electric arc furnaces, continuous casting tundish covers, incinerators, and other areas where these extremely high temperatures are encountered.
A high alumina, high strength, general purpose castable for service to 3000°F (1667°C). Used for casting burner blocks, door linings, car tops, crucible furnace linings and special shapes. High purity for special furnace atmospheres.
An economical, high alumina refractory for service to 2800°F (1556°C). Suitable for door linings, curbs and covers, pre-cast shapes, grey iron ladles, aluminum reverberatory furnace upper side walls and roofs.
A general purpose castable for service to 2600°F (1427°C). It is especially effective in casting door linings, boiler walls, monolithic car tops, hearths, fire boxes, as well as safety linings in continuous casting tundishes.
Blazecrete 2500 HS
A high-duty castable designed to withstand loads and resist normal abrasion and erosion at moderate temperatures to 2500°F (1371°C). Use with Blazelite 2100 for a dual component lining for combined high strength and insulation. Used for ash hoppers, incinerator floors, dust collector linings, cupola charging zones and fireplace sidewalls and hearths.
