Total Emissivity

In this paper, a novel optical technique for following the progress of the blister copper desulfurization process is presented. The technique is based on the changes observed in the continuous spectrum of the visible–near-infrared (VIS–NIR) radiation that the blister melt emits while the chemical reactions of the sulfur elimination process are taking place. Specifically, the proposed technique uses an optical probe composed of an optical fiber, a collimating lens, and a quartz tube, which is immersed in the melt. This optical probe provides a field of view of the blowing zone where the desulfurization reaction occurs. The experimental results show that the melt VIS–NIR total irradiance evolves inversely to the SO2 concentration reported by a gas analyzer based on differential optical absorption spectroscopy. Furthermore, the blister copper spectral emissivity as well as the total emissivity observed throughout the process show strong correlation with the sulfur content during desulfurization reaction.

Methods Of Application

Abstract Recommendations for shop cleaning and priming practices are broken down into seven categories: methods of surface preparation, methods of application, workmanship, supervision, inspection, priming, and fabrication. Surface preparation methods discussed include solvent cleaning, hand cleaning, power tool cleaning, flame cleaning, brush-off blast cleaning, commercial blast cleaning, white metal blast cleaning, and pickling. Application methods considered include brush, spray, hot spray, airless spray, roller, and dip. 5.9.1, 1.7.1, 5.4.7
