Description

technical field [0001] The invention relates to a metallurgical method technology, more specifically, the invention relates to a detection and analysis method in blast furnace smelting of high-titanium all-vanadium titanium ore, which belongs to the field of metallurgy. Background technique [0002] The blast furnace smelting method of all-vanadium-titanium ore is a major issue in the field of metallurgy today. This method can completely get rid of the precondition of relying on the addition of ordinary ore for production. [0003] Vanadium-titanium ore is 300 kilometers below the mantle and rises to the surface through multiple movements inside the earth. The process is structured in the form of spar and spinel. Because the ore-forming principle is different from that of ordinary iron ore, its composition is very complex. There are 94 kinds of natural elements on the earth, and there are at most 51 kinds in vanadium-titanium ore, and many useful elements coexist; there are ...
