CALCAST® is a high performance
technical ceramic board
manufactured from Calcium Silicate.
The non-wetting properties of CALCAST®
are ideally suited for use in direct contact
with non-ferrous molten metal
applications. The higher density grade
exhibits extremely low shrinkage – ideal
for use in applications which require the
product to retain its dimensional integrity.
Densities range from 850kg/m3 through to
1050kg/m3 with operating temperatures
from 850˚C to 1000˚C. CALCAST® is
machined to bespoke shapes in our fully
automated CNC shop.
CALCAST® is typically used for
applications such as launder sections,
troughs, dams, skim-dams, sprue
bushes, intermediate tubes, nozzles,
down-spouts, plugging sticks, hot-top
rings and transition rings. CALCAST® is
also ideally suited as a hot-face lining for
holding furnaces and as an insulator in
various heat treatment equipment.
Other benefits include:
Non wetting to molten aluminium
Excellent insulation properties
Hot Face Lining for direct contact with Molten Aluminum in Dosing/Holding Furnaces
Oven and Dryer Shelving
Aluminium Consumables such as Floats, Spouts and Transition Plates
Back-up Insulation for Kilns and Furnaces
Non-wetting to most non-ferrous molten metals.
High chemical stability in alkaline media.Reactive in acid media.
