摘要
设法改善QT550-6的铸态金相组织和力学性能,实现铸态供货,取代传统热处理工艺,可节约能源降低成本。成功的关键就是对球墨铸铁的化学成分的控制,并配合适当的球化、孕育及冷却处理。
Take measures to improve the microstructures and mechanical properties of as-cast nodular cast iron QT550-6, so as to realize supplying castings in as-cast status instead of heat treatment, can both save the energy and reduce the cost, The key of such measures is to strictly control chemical composition and to conduct proper nodulizing treatment, inoculation and cooling treatment.
