Our company produces two basic materials – basalt and eucor.
First and more produced one is melted basalt. It is produced from raw material, which is world-unique by its composition. From melted basalt, which features excellent properties, particularly abrasion and chemical resistance, the company produces huge amount of products of wide applicability.
The second material produced by the company is material with the trade name eucor. This material features excellent properties, too, and additionally it is resistant to high temperatures, and it is used exclusively in industrial operations, e.g. as abrasion-resistant inserts for pipe protection.
BASALT
Basalt is natural material-stone, which belongs to such materials, whose lifetime has exceeded not only centuries, but also millenniums.
In the 20th century this kind of stone features much wider application in industry and civil engineering with development of petrurgy, i.e. processing of non-metallic ores by melting and casting.
Basalt is continuously melted in pit-type furnace heated by natural gas at approx. temperature 1280° C. At 1200°C it is cast (shaped) into metal or sand moulds, and after removing it, it is stored into continuously cooling tunnel furnaces until cooling after 16-21 hours, where it re-crystallizes and gains its end-use properties.
Use
Melted basalt features general applicability and therefore it may be found in various forms practically in all industrial sectors. Additionally, you may find it in interior areas as well, where its non-traditional appearance and excellent properties are used.
Main Physical Properties of Basalt:
Strength in compression min. 300-450 MPa (CSN EN 993-5)
Mohs hardness min. 8th grade (CSN EN 101)
Use up to 400 ° C
High chemical resistance
Wearability max. decrease 5 cm3/50 cm2 (DIN 28062, 52108)
Abbrasion resistance max. decrease 110 mm3 (CSN EN ISO 10545-6)
Imbition 0 % (CSN EN ISO 10545-3)

Thermal shock resistance up to 150°C
Bend strength min. 45 MPa (CSN EN 993-6)
Volumetric weight 2900-3000 kg.m-3 (CSN EN 993-1)
Products
Our company produces literally thousands of various products from melted basalt and this amount is constantly increasing due to our own development and to the requirements of our clients as well
Main groups of products from melted basalt:
• Pavements
• Tubes
• Bends
• Reducing pieces, T-pieces, Y-pieces
• Special shaped casts
• Split gutters
• Radial shape pieces
• Sewerage gutters, tubes, bricks
• Heading tubes
• IN LINE tubes
EUCOR
EUCOR is material produced by melting of suitable raw materials in electric arc furnace at temperature exceeding 2000° C, followed by crystallizing of the melt. The melt is cast into sand moulds. The final product is aluminium-zircon-silicate, composed from corundum, baddeleyite and vitreous phase.
Eucor features excellent properties, particularly hardness, resistance against high temperatures and chemical corrosion.
Use of products from EUCOR
Due to its excellent hardness they are applied under conditions of extremely heavy abrasive load, such as pneumatic transport of silica sand, sinter, mainly in the piping bends. Other examples are: lining of separators, spiral chutes, dragline conveyors, concrete mixers, blenders etc.
Eucor’s resistance against high temperatures enables its use for masonry of glass furnaces above the melt level, for special shape pieces of burner walls and burners themselves, for shape pieces of regenerative chambers, coke-oven platforms etc. An interesting opportunity is its use in fly-ash separators with high entry temperature, where all stated properties, incl. chemical resistance, might be used.
Main Physical Properties of Eucor:
Strength in compression min. 300 MPa (CSN EN 993-5)
Mohs hardness min. 9th grade (CSN EN 101)
Use permanently up to 1000°C, short-time up to 1100°C
High chemical resistance
Abrasive resistance max. decrease 30 mm3 (CSN EN ISO 10545-6)
