Abstract

The invention relates to a method for producing vanadiferous pigiron by adopting vanadiferous converter steel slag, which belongs to the field of metallurgy. The invention aims to provide a method for producing vanadiferous pigiron by adopting low-grade vanadiferous converter steel slag, comprising the following steps of: a, material mixing: evenly mixing vanadiferous converter steel slag, ferruginous materials, coke, river sand and fluorite in a certain weight proportion; b, smelting: heating the materials in the step a to the temperature of 1600-1650 DEG C, and preserving the heat for 2-4 hours for smelting to obtain iron scraps and molten iron; and c, separation: separating the iron scraps and the molten iron obtained in the step b, and cooling the molten iron to obtain vanadiferous pigiron. The method of the invention has simple technical steps, supplies a new way for recovering vanadium resources in the vanadiferous converter steel slag, in particular low-grade vanadiferous converter steel slag, and has wide application potential.

Description

technical field [0001] The invention relates to a method for producing vanadium-containing pig iron by using vanadium-containing converter steel slag, belonging to the field of metallurgy. Background technique [0002] Converter steel slag is the second largest metallurgical solid waste, and its comprehensive utilization rate is only about 10% at present, and most of it is used in low-grade applications such as cement iron correction material, dry-mixed mortar and road aggregate, which not only reduces The economic utilization value of the converter steel slag also wastes resources such as vanadium and iron in the converter steel slag. [0003] Yang Subo et al., Extraction and recovery of vanadium in vanadium-containing converter slag, "Steel", No.4, (2005) discloses the high-grade vanadium-containing converter slag (V 2 o 5 >2%) use the overfire method to extract vanadium, carry out pyrometallurgical treatment on the vanadium-containing converter steel slag to obtain v...
