Dross and ultrafine particulate formation in underwater plasma-arc cutting
Production rates and detailed chemical and physical characteristics of solid emissions from underwater plasma-arc cutting of non-active 304-grade stainless steel have been studied. Steel thicknesses of up to 40 mm have been cut in water depths of up to 10 metres. A hyperbaric vessel and a deep water test column and associated experimental equipment and techniques were developed for these studies. Concentrations and compositions of effluent by-product gases were also investigated. Quantitative data were collected and possible mechanisms investigated for the following aspects of the project: (i) distribution, particle size and composition of solid emissions; (ii) composition and flow rates of effluent gases; (iii) effect of depth and other cutting conditions on solid and gaseous emissions; (iv) filtration resistance characteristics of water-suspended particles, and (v) repeatability of cut quality and yields of emissions under standard cutting conditions.
