Trimming scrap occurs during the production process when the edges of coils are trimmed.
Light and medium scrap
Scrap castings 3a, crushed to handy size, in particular clean, thick-walled cast iron pipe scrap, cast iron scrap from construction sites, sewage pipes, plating and unfired furnace parts, unfired gratings and sectional boiler scrap, free of cast steel and fired furnace scrap, wrought iron and enamels
Cupola furnace scrap
Today this grade is more often called foundry steel scrap and is preferably structural steel, fragmentised to charging size. Hammer mill waste, iron section waste, superstructure scrap, spring steel and leaf spring scrap etc. are all well suited for use in foundry melting furnaces.
Machine castings 2a, fragmentised into handy sizes, in particular thick-walled pieces from machine tools, other machines and motors or engines, generally not less than 10 mm thick, filling plates, all free from steel and fired furnace scrap, wrought iron and enamels
Rails cut to foundry size
Special foundry steel scrap made of old pieces of rail, ideal length for use in foundries between 30 and 80 cm.
Nodular cast iron
This cast iron scrap (cast iron with nodular graphite) comes from equipment and components as unfragmentised material or material fragmentised into handy sizes with a unit weight of not more than 40 kg.
Discarded waste from the production process is understood by the caster to be uniform steel waste from one particular production machine in a steel-processing plant.
Deep-drawing sheet packs
Deep-drawing sheet steel (including car body sheets) is very good feed material which is pressed into packs of sheet of various sizes. No contaminants or foreign metals whatsoever must be pressed into packs of sheet.
