Are of high quality ductile cast
ing precision casting or sand casting
, reasonable design, precision machining and perfect quality control to make the casting product has the characteristic of low noise, high hardness, high life.
Applications such as engine crankshaft, connecting rod, etc.
1, strict with chemical composition of the original requirements of carbon and silicon content in liquid iron is higher than gray cast iron, manganese, phosphorus, sulfur in the lower ductile casting content.
2, liquid iron melt temperature higher than gray cast iron, to compensate for the ball, inoculation of liquid iron temperature loss.
3, spheroidizing treatment, namely nodulizing agent is added to iron.
4, adding nucleating agent to inoculation.
5, liquidity is poorer, ductile casting shrinkage is bigger, so you need a higher pouring temperature and the larger size of pouring system, reasonable application of riser and chill, in a sequential solidification principle.
6, heat treatment, the ductile casting as bearing parts need high hardness, often will cast iron pieces of quenching and tempering treatment at low temperature.
