| Abstract: | Simulating the solidification process of compressor exhaust cylinder,the optimized casting process was determined by designing reasonable gating system,subsidies and risers.Using EAF+LF-VD double smelting process,and careful controlling chemical composition,the content of inclusions and gas in liquid steel reduces,the purity of the molten steel improves,which can satisfy the quality requirements of purity liquid steel. |
