Abstract
The present invention is the barium titanium silicon iron master alloy.Be characterized in containing simultaneously in the alloy vanadium, titanium.Can be used for directly smelting the microalloyed steel of the Ti low alloyed steel of vanadium, steel alloy, particularly controlled rolling and controlled cooling.It can directly utilize the vanadium slag of China's Panzhihua Iron, and for a new way has been opened up in the comprehensive utilization of Flos Bombacis Malabarici vanadium titano-magnetite, simultaneously, the present invention can improve the rate of recovery of vanadium aborning, and the carbon content in the control alloy is for favourable condition has been created in steel-making.Owing to contain vanadium, titanium, silicon simultaneously in the alloy, so can reduce production costs greatly.
Description
The present invention relates to the iron-based master alloy.Mainly be applicable to and smelt low alloy steel and steel alloy.
The vanadium titanium to development low alloy steel, steel alloy, particularly to the vanadium titanium high-strength low-alloy steel of development microalloying, improves the quality of carbon steel as the alloying constituent and the widespread use at home and abroad of little treatment agent of steel, has critical role and remarkable economic efficiency.
Vanadium iron master alloy in the past, vanadiumcontent be all 40～75%, and titaniferous not, as russian patent SU1084329 and SU559992.So when smelting vanadium titanium high-strength low-alloy steel and microalloyed steel, when adding vanadium iron, also to add ferrotianium, very inconvenient, and also the easy oxidation of ferro-titanium, yield of alloy is low, and stable inadequately, content is restive; The ferrotianium production technique is complicated, the cost height.
The objective of the invention is to open up a new way for the comprehensive utilization of Flos Bombacis Malabarici v-ti magnetite ore resources simultaneously for smelting low alloy steel, steel alloy, particularly microalloyed steel provide a kind of new barium titanium silicon iron compound master alloy.
The present invention is a raw material with the vanadium slag of Panzhihua Iron, adopts electric silicothermic process, the compound master alloy of direct production barium titanium silicon iron.
In this compound master alloy, the content of vanadium should not surpass 30%, because of containing the vanadium height, must the raising vanadium slag in the ratio of vanadium and iron, thereby make in the prereduction treating processes, vanadium also commercial weight is big, has increased the loss (entering in the reduced iron) of vanadium, and the rate of recovery of vanadium is low, and the carbon content height of alloy, problems such as easily sticking furnace bottom are so in the alloy, content of vanadium is controlled at 20～25% and is advisable.The source of the titanium of this compound master alloy is exactly the titanium that utilizes in the vanadium slag; According to the content range of titanium in common low alloy steel and the microalloyed steel, more suitable in titanium content control 2～5% scopes.Silicon is with the ferrosilicon form in the compound master alloy, adds as the reductive agent of smelting ferrovanadium; During smelting, with addition of ferrosilicon quantity directly influence the rate of recovery of producing vanadium, improve silicone content and can improve the recovery rate of vanadium when alloy smelting, solve the low problem of vanadium recovery, and alloy of the present invention can be made reductive agent without aluminium, in alloy, there are certain restricting relation in silicone content and carbon content, by controlling suitable silicone content, carbon content in the may command alloy, not only can eliminate because of forming the difficulty that too much carbide alloy production brings, and for steel-making creates favorable conditions, being unlikely to increases carbon content because of adding this composite alloy.For this reason, silicone content is controlled in 20～30% scopes and is advisable.
In sum, the chemical ingredients (weight %) of the compound master alloy of barium titanium silicon iron of the present invention is: V20～25%, and Si20～30%, Ti2～5%, S＜0.04%, P＜0.1%, C＜0.3%, surplus is Fe.
The present invention is a raw material with the vanadium slag of Panzhihua Iron, adopts electric silicothermic process to produce.Its concrete technical process is:
The compound master alloy smelting-finished product of vanadium slag-magnetic separation-prereduction-barium titanium silicon iron.
Vanadium slag carries out prereduction after magnetic separation, make (FeO) as much as possible being reduced in the molten state vanadium slag, and (V
2O
3) be retained in the slag as far as possible; Vanadium slag after the prereduction of gained can enter electric furnace, directly smelts the compound master alloy of barium titanium silicon iron.
This method has changed existing vanadium iron production method, has saved vanadium slag earlier through this great operation of chemical treatment, has not only simplified technology, and has reduced cost widely.
Compare with existing similar ferro-vanadium etc., adopt the compound master alloy of the present invention, can directly smelt Ti low alloyed steel of vanadium and microalloyed steel, can directly utilize the vanadium slag of Panzhihua Iron, for a new approach has been opened up in the comprehensive utilization of Flos Bombacis Malabarici vanadium titano-magnetite; Simultaneously, the present invention also can improve the rate of recovery of vanadium aborning, and the carbon content in the may command alloy is for favourable condition has been created in steel-making; Owing to contain vanadium, titanium, silicon simultaneously in the alloy, so production cost reduces greatly.
Embodiment
The chemical ingredients scope of compound master alloy according to the present invention is a main raw material with the atomizing vanadium slag of Panzhihua Iron, adopts electric silicothermic process, has produced the compound master alloy of four stove barium titanium silicon irons on electric furnace.
The atomizing vanadium slag carries out prereduction after magnetic separation, gained prereduction vanadium slag is the raw material of the compound master alloy of electrosmelting.Simultaneously, as required, add the ferrosilicon of different quantities and lime, coke during smelting, behind electrosmelting, obtained the different compound master alloy of four stove chemical ingredientss.And they chemical composition analysis and fusing point, specific gravity test have been carried out.Table 1 is the chemical ingredients of the compound master alloy of four stoves.
