发动机的机体、缸盖、机床铸件等薄壁高强度灰铸铁件是当今铸件朝着“精化”、“强化”和“轻量化”发展的代表作。本研究是以发动机机体、缸盖和缸套等薄壁高强度灰铁件为对象,根据我国目前为数众多的冲天炉熔炼,大包浇注以及废钢供应不足的生产条件下,结合生产实际,以“强化孕育”的生产方法,提高薄壁高强度灰铸铁件材质的性能和质量。目 The engine body, cylinder head, machine tool castings and other thin-walled high-strength gray iron castings is today’s casting “refinement”, “enhanced” and “lightweight” development masterpiece. This research is based on the thin-walled, high-strength gray iron parts such as the engine body, the cylinder head and the cylinder liner. According to the current production conditions of large cupola smelting, large package pouring and insufficient scrap supply in our country, “Strengthen the birth of” production methods to improve the performance of thin-walled high-strength gray cast iron material quality and quality.
