Returnable and non-returnable losses rise during melting and casting of molten metal. Non – returnable losses arise by melting and metallurgical treatment of molten metal as a back wash of evaporation, chemical reactions between molten metal and refractory lining, molten metal and air and between molten metal and refining additions. Value of these losses depends on the kind of alloy, on used furnace and charge quality. Except non-returnable losses, the returnable losses creates by melting. They represent a diffe...

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...

The European foundry industry is the third largest in the world for ferrous castings and the second largest for non-ferrous ones. the annual production of castings in the enlarged European Union amounts 11.7 million tonnes of ferrous and 2.8 million tonnes of non-ferrous castings. The foundry industry is a major player in the recycling of metals. steel, cast iron and aluminium scrap is remelted into new products. The most possible negative environmental effects of foundries are related to the presence of a thermal...
