Special Refractory

Special Refractories are principally both oxides and non-oxides and derived composite mixture. They are specially being designed for specific raw materials and mixed as per the design mix to work against high temperature to safeguard the surfaces.

Any refractory material or a product, if it got added value with a mix design or a project-specific shape, with special thermal and physical, is always referred as Specials.

As a material required for specific application against heat, abrasion, load and self-weight, is added with high melting point oxides, high melting point non-oxides, and the derived composite compounds and reinforcing materials.

Pre Cast Refractory

Pre - Cast refractory is principally varied shapes that are made to assemble a system of burning or firing which also made the operations of the furnace or Kilns safely.

One important special shape is burner blocks with thermal shapes to assemble metal operating parts in the heat environment.

• Kiln Car Bottom
• Burner Blocks
• Ladle Liners
• Baffles
• Launders
• Crucibles
• Hearth Plates
• Stopper Rods
• Thermocouples
• Insulation LTM Blocks
• Pouring Nozzles

Functional Refractory

Functional refractory materials are fired or non-fired refractory materials that are mixed with granulated and powdered refractory raw materials and binders to form a certain shape and have specific smelting applications.

In industries like Steel and non-ferrous ore melting, high alumina at more than 99% ,high purity products are required to work against adverse temperature and chemical reactions.

These products are Client-specific with exclusive shape and dimensions.

• Calcined Aluminas (Particle Sizes varying at 2.5, 3.5 micron)
• Reactive Aluminas (Particle Size 0.6 micron)
• Dispersing Aluminas

Silica Bricks

Silica refractories are to have more than 90% Silica and characterized for high strength at high temperatures, residual expansion, low specific gravity, high expansion coefficient at low temperatures and low expansion coefficient at high temperatures.

The Silica compositions can be applied for hot patching, shrouds and bricks.

Silica Bricks & Blocks

Silica Bricks are made of quartz stone material, the content of SiO2 is more than 96%. The nature and craft process of silica bricks are closely related to the crystal transformation of SiO2. The density is an important quality indicator of silica bricks. The density of silica bricks should be below 2.38 g/cm 3. Silica Refractory Bricks have the advantages of high strength at high temperatures

Fused Silica Bricks & Blocks

Silica Refractory Bricks have the advantages of low thermal expansion coefficient, high thermal shock resistance, low thermal conductivity and low specific gravity. Silica Refractory Bricks are mainly used for Coke ovens.

Corundum Bricks

Corundum brick refers to refractory with alumina content ≥90% and corundum as the main phase. Corundum bricks are mainly used in blast furnaces, hot blast stoves, refining outside the furnace, and sliding nozzles.

They do exhibit high purity, high density and high performance, used in the large blast furnace and the ladle of the steel plant and achieved good results. It is the best lining material for all types of furnaces.

Alumina Hollow Ball Products

They are high-temperature products and energy-efficient lining material, as they have low density and low thermal conductivity.

Industrial Ceramics

Ceramic structural parts. Shapes, Monolithic components and assembled structures.

• Ceramic Sheets or Plates
• Ceramic Rods and Bars
• Ceramic Tubes
• Ceramic Rings (Raschig Rings)
• Ceramic Plungers
• Ceramic Flanges
• Ceramic Nozzles
• Ceramic Arms ( specific dimensions)
• Any Ceramic Structural Parts ( as per dimensions)

Plastic Refractory

Plastic refractories are in general amorphous refractory materials with good plasticity over a long period of time. It is composed of a special grade of refractory clay/mineral, plasticizer and proprietary admixture, as per the special design mix.

They are highly suitable for application in all types of heating furnaces, annealing furnaces and sintering furnaces
