Controlling cast iron gas defects. - Free Online Library
1/9/1993· Iron or steel scrap contains about 70-100 ppm of [N.sub.2,] but the opportunity for [N.sub.2] absorption during subsequent remelting is potentially greater in a low-carbon ferrous melt. The presence of a confinuous graphite film indies that the defect is caused by [H.sub.2], but it is difficult to distinguish between fissures caused by either gas.

Petroleum coke (petcoke) is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1,200 to 1,350 C (2,192 to 2,462F), to remove moisture, drive off volatile matters, increase the density of the coke structure, increase physical
Thermal Transformations of Nitrogen and Sulfur Forms in …
The chemical pathways for nitrogen and sulfur transformations during coalifiion are elucidated by comparing the chemical forms of unaltered peats, lignites, and coals and pyrolyzed peats. Nitrogen forms are characterized by a coination of X-ray photoelectron spectroscopy (XPS) and 15N nuclear magnetic resonance (NMR). In unaltered peats, the 15N NMR and XPS nitrogen (1s) spectra are
