Abstract
A process for preparing the VTi-alloyed pig iron from V-Ti magnetite includes proportionally mixing SiO2, V-Ti magnetite concentrate and additive, sintering, smelting at 1390-1440 deg.C while adding technological elements and casting.
Description
Affiliated field
The present invention relates to a kind of production method of alloy pig iron, particularly utilize red lattice vanadium titano-magnetite to produce the method for vanadium, the titanium series alloy pig iron.
Background technology
The geographic vanadium titano-magnetite of red lattice is that the Panxi Diqu composition is the most complicated, the contained element of general vanadium titano-magnetite kind more than 30, and the contained unit in Hongge Deposit district have nearly 50 kinds, half of the occupation of land nodularization periodic table of elements, can enter the kind more than 30 of molten iron, mainly contain Fe, V, Ti, Ni, Cr, Co, Ga, Sc, Cu, Mn, Nb, Ta, Se, Si, Te, Zr, platinum family and rare earth have certain content in the middle of ore, the existence of these elements, to chemistry and the physicals of improving the pig iron all is useful, so Duo useful composition concentrates in the ore body, is very rare in the world, or even unique.How to make good use of these element values and get fine research.Nine experts to the Panxi Diqu tissue whole nation of Fang Yi vice-premier study the comprehensive utilization of Panxi Diqu vanadium and titanium resources, have the expert side of giving to calculate an account always, and iron only accounts for 1/9th of Panxi Diqu schreyerite value.We have also calculated an account when research, by the existing market price, the value that enters beneficial element in the molten iron is greatly about 3000 yuan/t, get its center line also 1500 yuan/more than the t, utilize the beneficial element in the V-Ti alloyed pig iron of Hongge Deposit production can reach 2.3---2.7%, exceed 2 times of Flos Bombacis Malabarici mining area, wherein form a part Ni, Cr content more than 1% by 2, Mo, V, Si content are greater than 0.8%, all greater than the requirement of national low alloy steel to alloying element.Therefore, how to utilize these elements, be worth excellent research.By the smelting pattern of climbing steel at present, the wherein useful composition of oxidative extraction from molten iron, be processed into various iron alloys, be added to again and produce various steel alloys and alloy pig iron in molten iron or the molten steel, except that the V oxidation rate of recovery can reach 60%, the Cr oxidation ratio has only 64%, and the rate of recovery is less than 50%, Ni, Co not oxidation basically remain in the molten iron.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, and a kind of method of utilizing red lattice vanadium titano-magnetite to produce vanadium, the titanium series alloy pig iron is provided, and it is simple to operate, can efficiently utilize resource, and energy consumption is few, and cost is low.
Purpose of the present invention is achieved through the following technical solutions: selecting for use and climbing western red lattice v-ti magnetite concentrate is raw material, at first prepares burden, and the weight percent of furnish component is SiO
21～5%, high-Ti type V-Ti magnetite concentrate 99%～95% utilizes sintered material, adopts dual alkalinity, gets agglomerate; Advance stove then, Control for Kiln Temperature is at 1390～1440 ℃; Come out of the stove at last, in the slag ratio of titanium dioxide less than 23%, the SiO in the concentrate
2And TiO
2Content decide SiO in the batching
2Content.Suitably add other technology element in the smelting, regulate coherent element in the molten iron, molten iron is directly used the modified back of intermediate frequency furnace cast article.V can reach 0.45% in the pig iron, Cr0.8-0.9%, Ni0.18-0.4%, Co0.04%.Also can be in guaranteeing the pig iron V＞0.3% o'clock, according to customer requirements, adjust the interpolation element of Co, Ni, Cr arbitrarily,
By top narration as can be seen, the present invention has the following advantages: needn't be by the beneficiating ingredient in the oxidative extraction molten iron, but directly contain the pig iron of various alloying elements, solved the biggest problem of Hongge Deposit development and use, reduced the waste of resource, reduce cost, be suitable for big industrial production.
