精密铸造Tribaloy T-800合金轴套

采用硅溶胶精密铸造工艺,生产了一系列Tribaloy T-800合金轴套,铸件经过热处理,材料相关性能指标达到技术要求。Tribaloy T-800合金产品在熔炼浇注时需要注意加料顺序,熔炼温度,钢水降温静置过程,浇注温度,并在浇注完成后采用浇冒口覆盖保温剂,缓慢冷却来控制铸件的凝固温度,从而获得Laves相充分形成的合格铸件。

Production of Tribaloy T-800 Shaft Sleeve by Investment Casting

Tribaloy T-800 shaft sleeves were produced by silica sol investment casting.After heat treatment,the shaft sleeves meet the requirements.During smelting and pouring process,some key points were paid attention such as the sequence of materials puting into the medium frequency induction furnace,melting temperature,liquid steel temperature-reduction process,pouring temperature.In addition,the riser was covered with thermal insulating agent and controlling the solidifying curve,keeping the castings cool slowly,so shaft sleeves with full Laves′phases were produced.
