Products Range

High Alumina Refractories

Manufactured with high purity sintered bauxite and select clays. These are versatile bricks for temperatures ranging upto 1500c (2732F).  

Lanexis also offers dense grades with low porosity, high strength and hot load strength. These bricks also comprise of Medium -High- Superduty Bricks.

Our Range: 

  • Durabrick 50 

  • Durabrick 50S 

  • Durabrick 50Dz

The 60% alumina range is wide and produced from  calcined bauxitic kaolin and high purity clays with low impurities. These brick are used in the steel industry, as well as rotary kilns. As a result of firing to high temperature, these bricks have low porosity, excellent strength and creep resistance, and good thermal stability at high temperatures. Phos bonded grades are available. 

Our Range: 

  • Durabrick® 60

  • Durabrick®62D

  • Durabrick® 60P 

  • Durabrick® 65

  • Durabrick® 65S

70% Alumina bricks are the most widely used refractory brick because of its excellent performance in multiple environments. These bricks have superior high- temperature strength and refractoriness and controlled porosity. 

70% RKB’s offer high expansion which is beneficial for a tight fit in Rotary Kilns. 

Applications include the steel-industry and various rotary kilns. The Phosphate bonded grades offer higher strength and plasticity. 

Our Range: 

  • Durabrick® 70

  • Durabrick® 70Li

  • Durabrick® 70P 

  • Durabrick® 75

  • Durabrick® 70D

  • Durabrick® 70S

Lanexis 80% alumina bricks are manufactured with high quality calcined bauxite from South America. We also add various amounts of other fine aluminas and clays for superior performance. 

Our 80% bricks offer excellent strength and thermal shock resistance. They are resistant to most slag conditions present in steel ladles. 

The mullite bonded phosphate grade offers higher thermal shock resistance and excellent alkali rating at high temperatures. 

Our Range: 

  • Durabrick® 80

  • Durabrick® 80LF

  • Durbrick 80P 

  • Durabrick® 85

  • Durabrick® 85P 

90-99% Corundum & Mullite based bricks are extremely high performance, high-quality bricks. They exhibit very low creep, very good thermal shock resistance and excellent hot load strength For high temperatures up to 1850 °C (3362F).

Capable of handling very difficult applications- These are used in Petrochemical, Slphur Recovery Units (SRU), Carbon Black Reactors, Secondary Reformer Domes & slagging rotary kilns, where it resists corrosion and penetration by slag. 

Our Range: 

  • Durabrick® 90

  • Durabrick® 90HF

  • Durabrick® 90P 

  • Durabrick® 99HF

  • Durabrick® 99D

“Latest Innovation in the World of Refractories”

Lanexis innovative Silica Mullite Bricks offer high strength with inbuilt insulation, thermal shock resistance & low thermal conductivity.

The innovation is the development & blending of high strength insulating backup material with a density of 1.8g/cm3 & still highly insulating.

Our Hybrid range of refractories can save up to 25% of heat losses in rotary kilns, ladles & static furnaces providing unmatched thermal performance and quick ROI.
