The formation of iron silicates during casting and the resultant penetration can be eliminated by replacing silica with carbon sand. 2] combine to form a fluid slag that easily penetrates the molding media, resulting in an iron oxide iron silicate phase on the casting surface. This iron silicate slag, sometimes containing small amounts of MnO, was found to be intrinsic to white iron at temperatures below 2530-2600F. |
