Ductile Iron Spheroidal Graphite Introduction
Ductile iron is a kind of high-strength cast iron material. Its comprehensive performance is close to that of steel. It is based on its excellent performance and has been successfully used to cast some parts with high stress, high strength, toughness and wear resistance.
Ductile iron is obtained by spheroidizing and inoculation to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, resulting in higher strength than carbon steel.
Cast iron is an iron-carbon alloy with a carbon content of more than 2.11%. It is obtained by high-temperature melting and casting of steel and its alloy materials such as industrial pig iron and scrap steel. In addition to Fe, carbon in other cast irons is precipitated in the form of graphite. If the precipitated graphite is in the form of a strip, the cast iron is called gray cast iron or gray cast iron, the cast iron in the form of a worm is called vermicular cast iron, and the cast iron in the form of a floc is called white cast iron or code iron, and is spherical. Cast iron is called ductile iron.
The chemical composition of ductile iron except iron is usually: carbon content of 3.0 to 4.0%, silicon content of 1.8 to 3.2%, total manganese, phosphorus and sulfur content of not more than 3.0% and appropriate amount of spheroidized elements such as rare earth and magnesium.
1.Q: Where is your factory located?
A: Our factory address is :Zhongyao, Xishan district, Wuxi, Jiangsu, P.R.China
2.Q: As the shipping period will take long time, how can you make sure the machine won’t be broken?
A: Our machine is film wrapped, to make sure the machine can be delivered to our customer smoothly, we will use the steel wire to fix the machine with the container.
3.Q: After we placing an order, will you arrange the installation of the machine at present?
