摘要
本文研究了不同断面球墨铸铁件加热和冷却的温度场,并定性地描述断面太小、冷却速度和基体组织、机械性能的关系曲线,据此揭示了取消保温、强化冷却的快速正火工艺。
Synopsis: The paper studies heating and cooling tcmpcraturc area of nodular cast iron in various sections,describes relating curve between section size, cooding rate and matrix structure, as well as mechanical properties. And it shows a fast normalizing technology with cancelling holding and intensing cooling.
