Ductile iron is currently one of the most popular construction materials. Its mechanical properties are close to those of steel. The basic material in the production of ductile iron is gray iron, which can be produced in a cupola or in an electric induction or electric arc furnace. After tapping the gray cast iron from the furnace, the gray cast iron is processing into ductile iron. This process is called modification. Magnesium and its alloys and cerium are most often used as modifiers. In addition to the modific...

Castings production cover different technologies of mouls and cores production, different technologies of metal melting (depended on casting material) and technologies of pouring. All these technologies have got some advantages, disadvantages and generate some kinds of by products.There are described in the contribution the basic technologies of moulds production (sand casting, shell moulding, investment casting, lost foam casting, shaw process, vacuum process), pouring technologies (gravity casting, die casting,s...

Foundries melt ferrous and non-ferrous metals and alloys and reshape them into products at or near their finished shape through the pouring and solidification of the molten metal or alloy into a mold. The foundry industry is a differentiated and diverse industry. It consists of a wide range of installations, from small to very large, each with a combination of technologies and unit operations selected to unit the input, size of series and type of product produced by the very specific installation. The foundry proc...
