精密铸造铸件的生产流程及工艺控制

摘要

介绍了精密铸造铸件的生产流程和工艺规程方面的注意事项,包括蜡模工序的工艺控制、制壳工序的工艺控制、熔炼浇注工序的工艺控制、落砂清理工序的工艺控制、热处理工序的工艺控制、清理工序的工艺控制,得出以下结论:熔模精密铸造工序较繁杂,每一道工序都应严格控制,才能保证所生产的铸件合格,因此,操作人员必须严格执行工艺规程,工程技术人员也应不断巡查各个工序生产状况,根据生产作业条件的变化,及时调整生产工艺,这样才能保证铸件高质量、高出品率.%The precautions in the production process and process specification of precision invested mold castings were introduced.That includes process control of wax mold process,crusting process,melting and pouring,sand shakeout,heat treatment,process control clean process.The conclusions were draw as following:precision invested mold casting process was a complicated one.Each process should be strictly controlled in order to ensure the production of castings qualified.Therefore,the operator must strictly implement the process rules and engineering and technicians should continue to inspect the production of various processes.Timely adjust the production technology according to the changes in production conditions to ensure high-quality castings and high yield.
