Material for metal casting equipment

摘要

A process is described for the production of a material for the manufacture of metal casting equipment in which an aqueous slurry comprising ingredients for the formation of a calcium silicate matrix and polyacrylonitrile-based carbon fibre is moulded, and the moulded body is autoclaved to produce a calcium silicate matrix substantially comprising tobermorite. The aqueous slurry contains from 1.5 to 25% by weight of a pre-autoclaved calcium silicate slurry.
