THE sleeve of super large scale high alloy centrifugal composite
casting roller( CCCR)
National ivitiate super large scale multi purpose centrifugal
composite casting roller.It can be used to support large scale
equipment due tu the virtue of high surface hardness, fine
configuration, stabilize performance, evident composite layer, good
inner machining function and to replace import products.the
technique of hot roller drilling is excellent, all the ends surface
are grey cast iron and has the good drillability.
THE centrifugal composite casting thchnique
The solidfying is under the action of the centrifugal force, so it
has the high density, white iron uniform layer andthere is not any
defect of gas hole, sand explosion and residue.
The centrifugal casting roller can be inlaid with a sleeve.it can
to reduce the consumpsion of raw materil and the weight of the
IT is very convenient to drill hole due to the uniform white casing
The working surface hardness of the CCCR can be produced acoording
to the demand of the users, up to HS726, in general.it has the high
anti wear property, good inner ductility and steady quality.
The working layer of the roller are uniform and there is a small
hardness variation( bellow HS5) .the quality steability of the
roller is assured.
Long working life( more 3-5times working life than the verti cal
static casting rollers) can save number of facts for the users.
The variety scale rollers can be produced according to demand of
the users( the maximum up to $ 1000* 8000mm)
