ings' target='_blank'>casting is a casting process, are made from rare earth magnesium nodulizing agent, cupola and grey are the same.
Ductile casting small make up will come today to tell you about the required notice.
1, strict with chemical composition, the original requirements of carbon and silicon content in liquid iron is higher than gray cast iron, manganese in lower nodular cast iron
, phosphorus, sulfur content.
2, liquid iron melt temperature is higher than in gray cast iron, to compensate for the ball, and liquid iron temperature loss during processing.
3, spheroidizing treatment, namely nodulizing agent is added to iron.
4, adding nucleating agent to inoculation.
5, nodular cast iron liquidity is poorer, shrinkage is bigger, so you need a higher pouring temperature and the larger size of pouring system, riser, reasonable application of cold iron, in a sequential solidification principle.
6, heat treatment.
Above is about ductile casting required notice, the hope can help you.
Today small make up to you at this point, let's see you next time.
At the same time, as the recent research of XEX shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
