[0034] MnV 2 O 5

[0035] Table 1

[0036] First, add 2000kg of bottom coke to the empty furnace of 1800KVA electric furnace; according to the batch ratio of 400 parts of vanadium slag, 600 parts of manganese ore, 236 parts of coke with particle size of 10mm~25mm, 47 parts of silica and 90 parts of limestone, stir well and add to the furnace. Inside; adjust the secondary output voltage of the electric furnace transformer (with a power of 1800kVA) to the lowest level of 73V; after power-on, the primary current is slowly increased from 10A to 120A, and the furnace will be released after 6 hours; the slag and iron after the furnace are separated to obtain the slag and silicon-manganese-vanadium composite alloy .

Abstract

The invention relates to a production method of a silicon-manganese-vanadium composite alloy, and belongs to the technical field of metal smelting. According to the method, vanadium-containing steel slag, manganese ore and silica are taken as raw materials, a proper amount of solvent is added, and submerged-arc smelting is carried out in a submerged arc furnace with a short furnace body. 90% of vanadium in the vanadium-containing steel slag can be enriched in the alloy to obtain the silicon-manganese-vanadium composite alloy, and the vanadium-containing steel slag is well utilized; and the production process is simple, the operability is high, the production cost is low, and the production method is conveniently carried out in industrial production.

Description

Technical field [0001] The invention belongs to the technical field of metal smelting, and particularly relates to a method for producing a silico-manganese-vanadium composite alloy by using vanadium-containing steel slag, manganese ore and silica as raw materials. Background technique [0002] Vanadium is known as the "universal alloy". About 85% of vanadium is ultimately used in the steel industry, and the remaining 15% is used in chemical and energy storage battery industries. Adding a small amount of vanadium to steel can refine the structure and grains of the steel, increase the grain coarsening temperature, and increase the strength, toughness and wear resistance of the steel. [0003] A small amount of vanadium is added to alloy the silico-manganese steel. It can increase strength while maintaining plasticity and toughness. Due to the current vigorous development of high-strength steels: the production of high-strength steel pipes, high-strength rebars and high-speed rail ...
