After casting, the inlet systém castings cool on the conveyors at the end of which the molds are broken on a vibrating grate so that the inlet systems are separated from the sand mold. Inoculation of the the metal stream ensures the correct structure of ductile iron after casting, ie the formation of spheroidal graphite during solidification of the metal, eliminates the effect of inoculum fading and minimizes the necessary amount of inoculum per 1 kg of cast metal. The shape of the ladle guarantees the ideal use of magnesium for modification in the production of ductile iron.Īfter the modification, the slag is removed from the surface and the metal is poured into an automatic casting machine, which casts the metal into molds from a uniform bentonite mixture at a high rate. After melting, correction and inspection of the chemical composition, the metal is poured into a modification ladle. The charge consisting of a cast iron door, steel scrap, crude iron and alloys is placed in the furnaces by means of vibrating loading trolleys. We have a separate division for the production of cylinder liners. We produce castings for large-scale production of simple and complicated shapes in the weight category of 0.1 to 4 kg. They are designed for compressors and camshafts of internal combustion engines. The foundry produces small castings, used in the automotive field.
The technologies of metal melting and subsequent casting are completely independent of each other in both operations, as well as in the entire process of cooling, finishing, final inspection and subsequent dispatch.Ĭurrently, our foundry produces castings for major multinational companies operating worldwide. They are centrifugally cast into shell linings.
The gray iron foundry is focused on the production of cylinder liners for diesel engines. Ductile iron castings are cast in sand molds. The foundry of Seco Industries, s.r.o., which is a Czech company, boasts with more than a century of tradition in the production of ductile and gray cast iron castings.
