The horizontal type centrifugal casting machines are used to produce the
duplexed mill roll shell/outer layer. The roll casting process divided into two
steps. The first step is the horizontal casting of roll shell/outer layer, the
second step is the vertical static casting of roll core. The two steps are
proceeded continuously in sequence in two separated casting sites. After the
static casting is finished, the newly casted roll will be positioned in the
ground pit for curing for 24 hours in a certain degreed temperature. Comparing
with vertical type centrifugal casting machine, the horizontal type roll
centrifugal casting machine’s cost is cheap, investment is low and more
flexible, but its mechanization degree is low, thus the labor cost is on high
side because the two casting process (centrifugal casting and static casting)
need to be done by two separated machines in two different casting sites.
The horizontal mill roll centrifugal casting machine adopts fully automated systems utilizing programmable logic controllers (PLC) with functions of automatic pouring, automatic mold coating, automatic mold inner wall cleaning and automatic extraction. The duplexed mill roll’s diameter ranged from 300mm to 800mm with length ranged from 500mm to 5,000mm.
