Converter slag forming process for rapid slagging

The invention discloses a converter slag forming process for rapid slagging and belongs to the technical field of converter processes for steel production. The converter slag forming process is used for rapid slagging of a converter. According to the technical scheme, in the converter slag forming process, the rotating speed of a fan is reduced before waste molten iron is added into the converter, lime powder of a small particle size is added in advance, and waste caused when lime powder of an extremely small particle size is sucked away by the fan is avoided; in addition, an initial slagging reaction is completed under the impact of the molten iron in the molten iron charging process, the rotating speed of the fan is increased to a normal value after lime powder is added, and lime blocks are added in the converting process. By means of the converter slag forming process, the slagging speed at the earlier smelting stage of the converter is effectively increased, and meanwhile waste caused when lime of an extremely small particle size is sucked away by the fan in the smelting process of the converter is reduced. The converter slag forming process is an innovation, solves the problem that the particle size of lime can not meet both sides, which brings trouble to slagging of the converter for a long term, effectively increases the slag forming speed in slagging of the converter, reduces the lime consumption in the slagging process, lowers production cost and improves the dust removing effect.
