EUCOR is material produced by melting of suitable raw materials in electric arc furnace at temperature exceeding 2000°C followed by crystallizing of resulting melt. The melt is cast into sand moulds by common casting method.
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 extreme heavy abrasive load, such as pneumatic transport of silica sand, sinter, mainly in the piping bends. Other examples cover lining of separators, spiral chutes, dragline conveyors, concrete mixers, blenders etc.
Resistance against high temperatures enables use for masonry of glass furnaces above the melt level, special shape pieces of burner walls and burners themselves, shape pieces of regenerative chambers, coke-oven platforms etc. An interesting opportunity is use in fly-ash separators with high entry temperature, where all stated properties, incl. chemical resistance, might be used.
Due to its high strength and abrasive resistance the EUCOR may be successfully applied in certain metallurgic operations for transport of scale and slag. Wire works use with satisfaction eucor conductors - racks.

EUTIT s.r.o. delivers from eucor material particularly casts for inserts of piping pieces, but also flat tiles, radial tiles, tailored shape pieces for lining of steel jackets acc. to drawing documentation from customers. Eucor is also basic material for production of complex casts for glass processing sector, metallurgical plants, power and heating plants etc.
These enterprises, but also others, order piping elements lined with eucor, too.
Main groups of products from eucor:
- Radial shape pieces
- Reducing pieces, T-pieces, Y-pieces
