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