【Abstract】 Synopsis Industrial scale experiments of powder injection have been conducted at a 12t ladle by injecting CaO+CaC 2+CaF 2(lime plus calcium carbide plus fluorspar) with outlet charge powder injection equipment. Results show that excellent outcome of desulphurization can be achieved and smooth and reliable operation of the equipments ensured providing sufficient quantity of injection powder can be supplied, and thus transfer of injection powder in an appropriate ratio of powder-gas phase is realized.更多还原
