Blast furnace overhauling residual iron placing device and method

Abstract

The invention provides a blast furnace overhauling residual iron placing device and method. The blast furnace overhauling residual iron placing device comprises a residual iron groove, a residual iron platform, multiple hot metal ladles and multiple hot metal ladle diversion trenches, wherein the upper end of the residual iron groove corresponds to a residual iron port of a blast furnace so as to guide the residual iron in the blast furnace to flow out of the blast furnace; the residual iron groove is formed in the residual iron platform; the hot metal ladles are linearly arranged and used for collecting residual iron; the hot metal ladle diversion trenches are respectively connected between adjacent hot metal ladles to connect the hot metal ladles together; and at least one hot metal ladle diversion trench is connected with the lower end of the residual iron groove, so that the residual iron in the blast furnace sequentially passes through the residual iron groove and the hot metal ladle diversion trenches and flows into the hot metal ladles. The device provided by the invention has the advantages of simple structure, convenience in manufacturing and mounting, easiness in operation, safety and reliability and the like, can guarantee timely discharge of residual iron, prevents molten iron from burning out the hot metal ladles and a hot metal ladle car in the residual iron discharge process, and saves the overhauling time.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a device and method for discharging residual iron in a blast furnace overhaul that can easily and safely discharge residual molten iron in the furnace. Background technique [0002] In the field of iron and steel production, when the iron-making blast furnace is shut down for overhaul, after the blast furnace is finished with the last furnace iron, there is still a large amount of residual molten iron inside the blast furnace. Exhausted. Once the residual iron port is opened, the molten iron will flow out continuously, and the molten iron must be sent into the pre-prepared molten iron tank through the residual iron release device. [0003] The normal tapping of the blast furnace flows into multiple molten iron tanks through multiple tributary iron troughs. The process of discharging residual iron is different from the normal tapping of blast furnace, and a residual iron discharging de...

AI Technical Summary

Problems solved by technology

However, this method needs to open the residual iron port twice to discharge the residual iron, which is time-consuming, laborious and unsafe.
