METHOD OF FABRICATING AN INVESTMENT CASTING MOLD AND SLURRY THEREFOR |
| 摘要 |
A method of fabricating an investment casting mold includes using a zircon-containing slurry to form a facecoat of a refractory investment wall of a mold cavity in an investment casting mold. The zircon-containing slurry includes, by weight, at least 70% of zircon powder. Also disclosed is a slurry for use in an investment casting mold. The slurry includes, by weight, at least 70% of zircon powder, 10%-30% of colloidal silica material, and 1%-10% of a carrier solvent. The method and slurry can be used to fabricate an investment casting mold that has a refractory investment wall with a facecoat having, by weight, at least 70% zircon. |
