MgO Refractories in the Basic Oxygen Steelmaking Furnace

Abstract: The BOF presents an example of a hostile, complex, transient thermomechanical and chemical environment, drawn from a major commercial industry. The most modem and successful refractory linings developed for these furnaces are composed of magnesia and carbon: a ceramic composite. The character of these refractory materials is traced from its origin in processing through interaction with the corrosive BOF service environment, and the bases of durability are discussed. Present performance is illustracted by a case study.

Chemical Properties of Refractories

Abstract: The immense variety of chemical aspects of refractories applications is sampled by descriptions of a few MgO and Al2O3 types and of their interactions with severe use environments found in the steel, glass, and other process industries Some chemical origins of mechanical behavior and corrosion lifetime are illustrated

Al-Mg-Si Alloy Exhibiting Superior Combination of Strength and Energy Absorption

Abstract: The present invention relates to an aluminum 6XXX (Al-Mg-Si) alloy extrusion component exhibiting a superior combination of strength and energy absorption for crash management applications in automotive markets and for other applications where energy absorption is a critical property. These components provide yield strengths greater than 260 MPa, and preferably greater than 280 MPa, while simultaneously providing energy absorption per unit cross-sectional area of greater than 20 kJ/mm using the defined crush testing parameters in the present specification.

Aluminas in Air Pollution Control

Abstract: Alumina and alumina based sorbents, catalysts, and catalyst supports are used in many air pollution control applications because of high surface area, porosity and thermal stability. Although some air pollution abatement may use once-through sorbents, problems of solid waste make regeneration attractive, especially where high volume pollutants like SO2 can be converted to storable sulfur. “Alkalized alumina” as a regenerable SO2 sortent has been tested extensively with some recent reports indicating possible effectiveness on NOX as well. High area alumina is used as support for catalytic materials in conversion of SO2 to H2SO4, while special aluminas provide the best catalyst for the Claus process for conversion of H2S and SO2 to sulfur. The wide range of available alumina properties of value in air pollution abatement in smelters, power plants and chemical processing are illustrated by discussing (a) dry sorption of SO2 by alkalized alumina, (b) absorption of SO2 in slurries of basic aluminum sulfate, (c) catalytic conversion of SO2 to H2SO4, (d) catalytic conversion of SO2/H2S to elemental sulfur in the Claus process.
