Rapid heat conduction sand mold material and preparation method thereof
The invention relates to a rapid heat-conducting sand mold material and a preparation method thereof, the sand mold material is mainly composed of heat-conducting aggregate and a high-temperature working matrix, the raw material of the sand mold material is alpha-alumina powder, and the raw material is added with high-heat-conducting aggregate, magnesium oxide aggregate and binding agent RTV silicone rubber. Wherein the main raw materials of the heat-conducting aggregate comprise sintered magnesium oxide particle aggregate, graphite particles, a water glass solution and silica fume. By adopting the casting mold as a casting mold, the stress cracking phenomenon on the surface of a zirconium chromium corundum blank is obviously reduced, the product percent of pass of the material is obviously increased, and the problem of stress fracture in the casting zirconium chromium corundum annealing process can be effectively solved.
本发明涉及一种快速导热砂型材料及其制备方法，其砂型材料主要由导热骨料与高温工作基质组成，其原料为α‑氧化铝粉、外加高导热骨料、氧化镁骨料、结合剂RTV硅橡胶，其中导热骨料主要原料为烧结氧化镁颗粒骨料、石墨颗粒、水玻璃溶液、硅灰。通过采用本发明作为浇铸模具，锆铬刚玉坯体表面的应力开裂现象明显降低，材料的产品合格率显著上升，本发明能有效解决熔铸锆铬刚玉退火过程中的应力断裂问题。
