| titleOfInvention | Fused silica based, deformation resistant mold |
| abstract | The invention relates to a mold shell based on fused silica and anti-deformation, comprising a mold shell surface layer and a multi-layer mold shell back layer. The particle size of the zircon powder for preparing the slurry in the surface layer slurry is 300 mesh to 1250 mesh, and the aggregate of the surface layer sanding layer is zircon powder, and its particle size is 100 to 150 mesh; The shell back layer slurry and the back layer sand-spraying material are solidified and combined to form. The particle size of the fused silica powder and fused silica sand for preparing the slurry in the back layer slurry of the mold shell is 100 mesh to 1250 mesh, and the back layer is sprinkled with sand. The aggregate of the layer is quartz sand, and its particle size is 10 to 50 mesh; the surface layer slurry of the shell uses zircon powder, and the back layer slurry uses fused silica with a very small expansion coefficient, and the obtained shell has a small thermal expansion coefficient, And strictly control the particle size of the powder used to reduce the difference in thermal expansion coefficient between the shell surface layer and the shell back layer. |
