Plant 1 MKZ Fireclay Factory

About plant

Production plant 1 MKZ Fireclay Factory is located in Rájec-Jestřebí in South-Moravian Region and it has been built in 1908 as brickyard and rebuilt in 1911 to produce the fireclay. Plant produces and sells fireclay refractories and high alumina refractory shaped products. These products are used mainly in foundries, stove-building, building industry and also in manufacturing of industrial furnaces. Fireclay products include three production branches: fireclay bricks for building industry, stove fireclay and casting fireclay. 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. Fireclay and high alumina bricks are manufacture in more qualities for for use in very high temperatures up to 1 730 ° C. 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.
