24 Manufacture of basic metals
This division includes the activities of smelting and/or refining ferrous and non-ferrous metals from ore, pig or scrap,
using electrometallurgic and other process metallurgic techniques. This division also includes the manufacture of metal
alloys and super-alloys by introducing other chemical elements to pure metals. The output of smelting and refining,
usually in ingot form, is used in rolling, drawing and extruding operations to make products such as plate, sheet, strip,
bars, rods, wire or tubes, pipes and hollow profiles and in molten form to make castings and other basic metal
products.
24.1 Manufacture of basic iron and steel and of ferro-alloys
This group includes activities such as direct reduction of iron ore, production of pig iron in molten or solid form, conversion of
pig iron into steel, manufacture of ferro-alloys and manufacture of steel products.
24.10 Manufacture of basic iron and steel and of ferro-alloys
This class includes:
–
–
–
–
–
operation of blast furnaces, steel converters, rolling and finishing mills
production of pig iron and spiegeleisen in pigs, blocks or other primary forms
production of ferro-alloys
production of ferrous products by direct reduction of iron and other spongy ferrous products;
production of iron of exceptional purity by electrolysis or other chemical processes
– remelting of scrap ingots of iron or steel
–
–
–
–
–
–
–
–
production of granular iron and iron powder
production of steel in ingots or other primary forms
production of semi-finished products of steel
manufacture of hot-rolled and cold-rolled flat-rolled products of steel
manufacture of hot-rolled bars and rods of steel
manufacture of hot-rolled open sections of steel
manufacture of sheet piling of steel and welded open sections of steel
