What Drives Iron Casting Scrap Rates?

Ferrous foundries’ results can be improved once metallurgists and operators understand the role of oxygen – and how and why casting defects form.

Exciting New Properties in Molten Iron

Deoxidization is not impossible, and foundries that eliminate free oxygen in the melt are revealing an impressive list of material qualities, along with reduced casting scrap…

Eliminating Iron Casting Surface Defects

Oxides always form when oxygen atoms are present, and the risk of them agglomerating and reaching the casting surface is unnecessary gamble when deoxidation is possible.

Melting Iron Without Forming Slag

Oxidation is a natural effect, but eliminating the process of slag formation is simple, and the results can be significant for material quality and foundry productivity.

Evaluating Cupola Melting and Oxidation Losses

The melting cycle is a dynamic process in which clean charge materials lead to byproducts that can reduce the metallurgical quality of the iron produced, unless an effective treatment…

Optimizing Cupola System Design

Stopping molten iron oxidation is the first priority for foundries operating cupola systems. The next step is to initiate the system and melting process changes that will improve…

Cupola System Design Optimizes Melting Operations

A cupola’s thermal efficiency determines how effectively sensible heat is directed to the molten iron, and how much is wasted. Maximizing thermal efficiency requires the cupola…

Controlling Conditions for Cupola Melting

There are several steps to maximizing cupola operating performance, but the first and most important is to manage the detrimental influences of iron oxide.

Maximizing Cupola Performance

The challenge of metal oxidation is magnified in cupola furnaces because iron oxides are produced in greater volumes. The melting cycle needs to be examined to pinpoint exactly…

A Molten Iron Improvement Strategy

Clean, quality molten metal should be the goal of every ferrous foundry, and the technology is available to achieve it — but the results depend on you.

Treating Molten Metal to Reduce Refractory Erosion

Chemical treatment technology is making it possible to extend the service life of a furnace lining — while improving the quality of the iron produced.

Treating Oxidation to Reduce Iron Casting Scrap

The chemical process that leads to surface defects, inclusions, pinholes, slag, dross, and misruns is continuous and ongoing. The only way to stop it is to cut off the supply…

Controlling Molten Iron Chemistry and Metal Fluidity

Using metal cleanliness to prejudge molten iron’s fluidity is a breakthrough technology. It substantially reduces the risk for scrapped castings.

Controlling Iron Oxide to Stop Carbon and Silicon Losses

Iron foundries must address and eliminate the effects of oxidation by controlling FeO in slag contacting the molten metal.

Harmful Effects of Molten Metal Oxidation

Ferrous foundries accept free oxygen as an unfortunate byproduct of their work, but melting iron can be simpler and more cost-effective when free-oxygen atoms are under control…
