摘要： The invention relates to a process for the desulphurization treatment of a pig iron melt in a container. The characterizing feature of the invention is that the treatment is performed in three phases:In the initial phase such solids are injected that deoxidize the initial slag and increase its basicity and also produce a circulatory movement of the melt and form a basic deoxidized cover slag. In the middle phase the desulphurizing agent is injected for the main desulphurization and in the final phase such solids are injected that purify the melt and produce a final desulphurization and also so influence the desulphurization slag formed that its content of iron granules is low.
摘要翻译：本发明涉及在容器中对生铁熔体进行脱硫处理的方法。本发明的特征在于，处理分三个阶段进行：在初始阶段，注入这样的固体，使初始炉渣脱氧并增加其碱度，并产生熔体的循环运动并形成碱性脱氧盖渣。在中间阶段，为脱硫主要注入脱硫剂，在最终阶段注入固体，净化熔体并产生最终的脱硫，同时也影响铁颗粒含量低的脱硫渣。

摘要： An improvement in a process for dispensing a fluidizable solid from the lower portion of a pressure vessel equipped with a weighing device, a closable supply, a discharge, and a source of three gas flows, a first of which is applied within the vessel at a level above the solid to be fluidized, a second of which is applied within said vessel in a lower portion thereof, and a third of which is applied within the discharge orifice of the vessel, which discharge orifice terminates in a chamber, which improvement involves determining the amount of solid dispensed and determining the throughflow of gas in relationship to the amount of solid dispensed to maintain a constant gas/solid ratio while maintaining the pressures such that the pressure applied to the lower portion of the vessel is greater than the pressure applied at a level above of the solids which, in turn, is greater than the pressure applied to the discharge orifice, all of which are greater than the pressure maintained within the chamber, and an apparatus for carrying out the process embodying control devices to maintain the desired constant predetermined gas/solid ratio.
