Chilled Cast Iron DURANIT
Rolls from Chilled Cast Iron – which is the most common material for calender rolls – can be supplied as single-poured or double-poured rolls with grey cast iron core or nodular cast iron core. The excellent barrel surface with hardness ranges of up to 78 ShC provide excellent results to our customers.
Chrome Steel CROMANIT K
The double poured chrome steel roll which can be supplied with a hardness of more than 80 ShC, due to its carbide structure, excels due to a distinctly improved wear resistance with superior mechanical properties. It will be a pleasure for our specialists to give advice on the choice of an optimal material grade appropriate for your production.
FURTHER ROLL GRADES
For special applications or special requirements Karl Buch also supplies other grades, adapted specifically to their application. This range goes from Nodular Cast Iron rolls up to high alloyed Cast Steel rolls. It will be a pleasure for our specialists to give advice on the choice of an optimal material grade appropriate for your production.
Apart from the classic solid cast roll which is drilled afterwards, we also produce special constructions. Then the roll body or shell is provided with flanged-on, shrunk-in or glued-in necks or axes (for example rolls for IT calenders).
