ductile iron foundry process

Ductile ironprovides a designer with an exceptional combination of toughness, low cost manufacturing, and reliability.PropertiesofDuctile Iron. To create different grades ofductile iron, one must control the matrix structure around the graphite during the castingprocessor through subsequent heat treatment.

Q: When we produceductile iron, we use the pour-over method of treating the baseironduring furnace tapping. This method is less than ideal for our large treatment size and results in excessive alloy additions (>1.5% addition rate). We also struggle with inconsistent magnesium recoveries, excessive slag and dross, and significant temperature loss.

Yet it isductile ironthat has become one of the most popular types ofiron casting. Development ofductile ironcontinued into the 1950s, making theprocessofductile iron castingbetter leading to acceptance ofductile iron, acceptance proven out by the nine-fold increase in use during the 1960s as an engineered material for commercial applications.

The normal quenching and tempering treatment could increase the surface hardness to about HRC 30 to HRC 40 of Rockwell Hardness, this process includes the heat heated to880-930 centigrade, then quenching in the oil, then do the tempering treatment in 500-600 centigrade.

Faircast has been a leadingiron foundryfor decades, and we pride ourselves on going above and beyond to provide you the best qualityductile ironand grayiron castingin the Midwest. Our Quality Inspectors and Managers communicate with you to make sure yourcasting processgoes as smoothly as possible.

Visitors who tour a McWaneDuctilefacility are often surprised by how much work goes into makingDuctile ironpipe.The pipe starts out as scrap metal from old cars and demolished buildings that is melted down and given a new lease on life. Up to 95% of our product is made from recycled material.

In 1961, Wells Manufacturing Company introduced theprocessof continuousiron castinginto North America. Theprocesswas originally developed in Europe after World War II as an alternate method of producing castironbar stock without patterns and conventional molding methods.

Ductile iron castingrefers to aprocessin which magnesium / cerium (as an alloy of magnesium / cerium) is added to castiron. It reacts with the sulfur and oxygen in the moltenironand changes the way the graphite is formed.Ductilecastiron(also called as spheroidal graphite castironor nodular castiron) has been widely used as a main industrial material in place of high-grade castiron.

Ductile IronHardening Treatment : Hardening treatment toductile ironcould increase the surface hardness ofcastings, to make thecastingwith good hardness and abrasive resistance.. The normal quenching and tempering treatment could increase the surface hardness to about HRC 30 to HRC 40 of Rockwell Hardness, thisprocessincludes the heat heated to 880-930 centigrade, then quenching in …

To help reduce automotive CO2 emissions there is a continued trend towards lower weight, higher strength components. Here, Norbert Schütze of Foseco Germany details the transition of the manufacture of manifolds and turbochargercastingsin an automotivefoundryfromductile ironto steel, focussing on low emission coldbox binders, sand additives and high performance coatings.
