High temperature and high pressure valve casting manufacturing technology and application

The manufacturing process of the CF8C valve under high temperature and high pressure conditions is introduced. Propose the selection and setting methods of casting parameters such as parting surface, riser, gating system, and cold iron of stainless steel valve castings; adopt high silicon, high nickel, high temperature, high pressure double pipes to continuously blow oxygen and add alloys in time to quickly reduce the furnace Process measures such as internal molten steel temperature and reasonable power supply, and implement the smelting process of electric arc furnace return to oxygen blowing to smelt CF8C material. Practical application shows that the quality of the produced castings fully meets customer requirements
