Chill Roll Machinery

Our newly developed quality for flacking rolls has proved its value for many years. It is a trend-setter. The material is a static cast special alloy iron of our indefinite chill quality class. An important point here is that the cast iron is molten of diver's special pig iron qualities in a cold-blast cupola furnace & Rotary furnace. The surface hard nesses of these qualities are adjustable to a range of 400 .600 HV. The decline on hardness is minimal and even with a 20% reduction in diameter the surface hardness will still remain on the same level as with the initial diameter.
