• 論文の詳細を見る

• In the injection test of serpentine through one tuyere executed as a means to improve the furnace lower filling structure, the tuyere sampler insertion depth and the deadman temperature rose greatly by the amount of the fine serpentine injection of 20 kg/t or more. It is presumed for the melting point of slag piling up in the deadman surface part to decrease by the injection of fine serpentine through tuyere, for the fine ratio (−3 mm) of the melt origin and a slag hold-up ratio to decrease greatly, and for the gas and liquid permeabilities in deadman to have been improved. In addition, the possibility that the desulfurization reaction is able to be promoted efficiently while maintaining the active state of deadman and the possibility of the low temperature operation by the serpentine injection through tuyere were suggested.
