SEEIF Ceramic, a.s. is a producer and supplier of traditional refractories and wide range of refractory ceramic materials, including services and consultancy related to their use by the customer. Supplied products are intended mainly for the metallurgical, foundry and steel industry. 

SEEIF Ceramic, a.s. was established in year 2009 by the mergence of three traditional refractories producer in the Czech Republic – Moravské keramické závody, a.s., KERAVIT, spol. s r.o. and REFRAMO, s.r.o. As a result of this merge is an important, rising manufacturer and producer of shaped and monolithic refractories, focused mainly to foundries and ironworks.

Production plant 1 MKZ Fireclay Factory is located in Rájec-Jestřebí in South-Moravian Region. Plant produces fireclay and high alumina refractory shaped products. These products are used mainly in foundries, steelworks and stove-building industry. Fireclay and high alumina products for foundries (casting fireclay, foundry holloware) are used in gating systems for metal casting. Stove fireclay manufactured from both plastic mass and crumble mass are used as construction and non-construction linings of fireplaces, chimney-places and cauldrons. Special branch production line is manufacturing of heating elements – special fireclay shaped products with pressed-in electrical heating spiral – used as parts of ecological radiators for heating in habitable rooms.

Production plant 2 MKZ Refractory Masses is located in Rájec-Jestřebí in South-Moravian Region. This production plant focuses mainly on the production of monolithic masses for blast furnaces (tap hole clazs, gunning and ramming masses), including masses and accessories for foundries and steel works. The additional range of the plant production includes dried foundry sands.

Production plant 3 Keravit is located in Ostrava-Vítkovice, in Moravian-Silesian Region. It is a traditional refractory ceramic materials producer. Since its founding in the middle of 19th century, the plant focused on meeting the needs of metallurgical steel making operations in Vítkovice Iron Works, in particular in the range of production fireclay shapes for gating systems. This plant is european leader in production of high alumina gating systems for steel ingot feeding. Plant is also producer of wide range other refractories, produces structural refractory bricks for common and special industry needs and also produces unshaped refractories.

Production plant 5 MKZ Svitavy is located in  produces mainly wide range of goods based on graphite-fireclay compound and destined for the foundry and steel industries (graphite stoppers and nozzles, graphite crucibles, SiC monoblock stoppers, ladle bowls, pyrometric tubes). The other important production lines are heat-insulating moulded blocks IZOSPAR (light fireclay feeder bricks) mainly for foundry industry and variety of other thermal insulation shapes.
