components. broad range of materials for monocrystalline silicon ingot pulling we produce materials for a wide range of typical parts, inclu- ding heaters, crucibles, reflectors and heat shields made from high-strength, homogeneous fine-grain graphite (sigrafine) or carbon-reinforced carbon (sigrabond...
in a reduced share of electric arc furnaces in the total global crude steel production, which today stands at around 25%. electric arc furnaces use mainly ferrous scrap to produce steel. our estimates suggest that global scrap availability - the amount of ferrous scrap that can be collected and melted...
