Ductile iron castings are spherical graphite obtained through spheroidization and inoculation. Due to its excellent performance, ductile iron can sometimes replace cast steel and forged steel in use and is widely used in the machinery manufacturing i..
At present, the ball mills in the market are becoming more and more large-scale equipment, so we also put forward different views on the material requirements of the mill lining board.
High chromium cast iron as a high anti-wear material has been effectively used in machinery and metallurgical equipment such as crushing, grinding, and material transportation.
Ductile iron with its excellent performance can sometimes replace expensive cast steel and forged steel in use. Ductile iron castings are widely used in the machinery manufacturing industry.
Because of the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is superior to cast steel in reducing vibration ability, so it is more beneficial to reduce stress.
Another method is the ductile iron plant on the surface coated with some epoxy coal tar pitch, it is suitable for gas pipelines, sewage pipes, there are Good adhesion.
Ductile Iron temperature control in 1570 ℃ ~ 1610 ℃ into the spheroidization, the second birth, wet sand casting or coated sand shell type casting.
On the one hand, the temperature of the nodular cast iron is reduced on the one hand, and on the other hand, magnesium and rare earth elements form slag in the ladle and pouring system.
Wear resistance of high chromium cast iron is the best.It is most widely used, such as small and medium sized ball mill lining plate, and a small, hammer crusher and hammer mill, etc..
The melting temperature of high chromium cast iron is higher than that of general cast iron, about 1200 degrees Celsius, the temperature is about 1500 degrees.
