Some semi-dry Flue Gas Desulfurization ash (SDFGDA) were taken from sinter gas of steel factory and been oxidized at experimental condition. Oxidized ash, granulated blast-furnace slag (GBFS) and steel slag were grinded and used to prepare cementing materials. Scanning electron microscope (SEM) was employed to identify the samples in order to investigate their hydration structure. The result shows that cementing materials have good hydration properties and mechanical properties, the initial and final setting time are qualified. It is recommended to control the Blaine fineness, mount of SDFGDA, ratio of GBFS/steel slag, mount of clinker to be 4500cm2/g, 19%, 1:4, 20%, respectively, when prepare eco-cement with those materials.

Abstract AL 4565 alloy has a high level of austenitizers, which provides the microstructure with a high resistance to sigma formation during welding. The high nitrogen also gives the alloy superior strength among the austenitics. Applications include flue gas desulfurization and handling seawater. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-906. Producer or source: Allegheny Ludlum Corporation.
