Casted basalt tiles are commonly used in various construction and architectural applications due to their durability, strength, and aesthetic appeal. Some of the common uses of casted basalt tiles include:
Automobile brake testing is a critical aspect of vehicle safety and performance assessment. To ensure accurate and reliable results in these tests, the choice of materials for testing surfaces is crucial. Cast basalt has emerged as an ideal material for automobile brake testing due to its unique properties and advantages.
Extreme Hardness: Cast basalt is one of the hardest materials available, making it highly resistant to wear and damage. This characteristic ensures that the testing surface remains consistent over prolonged use.
Excellent Wear Resistance: The abrasion resistance of cast basalt is exceptional. This property is crucial for brake testing surfaces as it prevents surface deformation, ensuring consistent testing conditions.
High Temperature Tolerance: Automobile brake testing generates significant heat due to friction. Cast basalt can withstand high temperatures without losing its structural integrity, providing stability during testing.
Low Coefficient of Friction: The low coefficient of friction of cast basalt helps replicate real-world braking conditions accurately. This property ensures that the frictional forces during testing mimic those on actual road surfaces.
Chemical Inertness: Cast basalt is resistant to chemical corrosion, ensuring that it maintains its properties over time, even when exposed to various fluids used in brake testing.
Consistency: Cast basalt offers a consistent testing surface over time, reducing the need for frequent maintenance or replacement.
Realistic Results: Its low friction coefficient and resistance to wear and temperature make it suitable for replicating real-world braking conditions.
Safety: Accurate and reliable brake testing is essential for ensuring vehicle safety, and cast basalt contributes to this by providing a stable and durable testing surface.
Cost-Efficiency: While the initial investment in cast basalt may be higher, its durability and longevity lead to cost savings in the long run by reducing the need for frequent replacement.
Environmental Friendliness: Cast basalt is a natural material, and its long lifespan reduces the consumption of resources compared to alternative testing materials.
Friction Testing: Cast basalt is commonly used in brake dynamometer testing, where it serves as the friction surface for evaluating the performance of brake materials and systems.
Component Testing: It is employed in testing individual brake components, such as brake pads and rotors, to assess their wear characteristics and performance under various conditions.
Certification Testing: Regulatory bodies and automotive manufacturers use cast basalt in brake certification testing to ensure compliance with safety standards and regulations.
Basalt tiles can be placed and jointed in cement or specially-defined bonding agents, as demanded by the intended application. Basalt tiles can be provided with a central hole that is countersunk for individual bolting, or as ready-made liner plates and pipes.
Cast basalt tiles is mainly used in thermal power plants, steel mills, mines and other parts with heavy wear, such as raw coal bunkers, mine bins, coal unloading trenches, hoppers, ore troughs, flotation machines, chutes and other parts.
These very hard tiles are made for very heavy industrial use, but also feature a beautiful metallic sheen. Originally used for sewerage systems or piping pieces, these pavement tiles are made by melting natural basalt and casting it into metal moulds.

Hard & Compact Smooth & Inner Withstands High-Abrasion & Corrosion In any of the process industries especially Sled and Cement corrosion and abrasion lead to significant downtime of the plant. Further, the useful life or the equipment itself may get impaired because of the high abrasive nature of the materials being used. Thus, ‘wear mechanism’ results in hut down, replacement, etc., which is costly, resulting in loss to tilt: tunic of millions of dollars.
The bend radius should be minimum 3 times of the nominal bore. At discharge end of each bend, cast basalt lined straight pipe of length 5 to 12 times the nominal bore must be used.
Cast basalt can be used for the lining of pipework, chutes, bunkers, cyclones, and hoppers.
It has become the global standard in areas such as ash slurry pipework, often used at fossil-fuel power stations. It is an all-round cost-effective and adaptable lining material that extends the life of equipment in pipe or tile form where affected by erosion.
Cast basalt is well-proven in a variety of industries as a cost-effective, long-lasting lining material used to extend the operating life of equipment manufactured or lined with lower-wearing materials such as steel, cast iron, rubber, and polyurethane.
Cast basalt lined steel pipe, as both a wear—resistant and corrosion—resistant materials, the transport properties of wear or corrosion of materials, after thirty years of practical verification, cast basalt lined steel pipe can be well done.

Cast basalt is a mineral of exceptionally high abrasion resistance, unlimted resistance to moisture, high compressive strength and resistance to virtually all acids and alkalis and is completely corrosion free.
Cast basalt is produced by melting selected natural basalt broken into sizes of 20-50 mm in shaft furnaces at tempreatures around 1,300C, following by casting at which the metled basalt forms uniforms pherolithic crystals hence producing its typical physical propertics, in particular its exceptional hardness and wear-resitance.
Cast basalt reaches a value of hardness of 8( min ) on the Moh's hardness scale. for comparision : the highest value10is only attained by dimonds. by virtue of these properties,the silicate cast basalt provides outstanding protection against abrasion and scrubbing.
however, it is marked by asertain sensitivity ti impacts.Under Normal services conditions, cast basalt withstands tempratures up to approx.+ 350C or-40C. However Cast basalt sholud not be subjected ti temprature shocks.
Sizes : Cast basalt produces are manufactured as tiles, from pieces and segments. straight pipes are spun-cast, available for nominal bores of 32 to 600 mm with the wall thickness ranging from 20 to 30mm and a standard lenght of 500mm.samller nominal bores of straight pipes, pipe segment for radill of 40 to 3,000mm of vatrious angles, as well as special formpiece linings are pre dominately sand-cast. The standard wall-thickness is 20mm. depending on the respective quantity, steel moulds can also be used, the wall thickness in those cases usually being 30 to 40mm.
