Consumable pattern coating for lost foam castings |
摘要 |
The coated pattern is formed from a consumable pattern, preferably polystyrene, and is adapted to be decomposed and replaced by molten metal to form a casting. The improved coating is the dried residue of an aqueous coating formed from water, refractory particles, and from between about 25 wt-% and 75 wt-% organic polymer on a non-volatile solids basis (i.e., dry film basis). Lustrous carbon is reduced when casting iron.
