Abstract
The ferro-titanium alloy with titanium content of 20-75 wt% is produced with recovered titanium and sponge titanium as raw material, which, after analysis, crushing, deoiling and roasting, is smelted together with low-carbon steel in a certain ratio inside the crucible of vacuum induction furnace. The said method can smelt ferro-titanium alloy of different quality requirement.
Description
The present invention relates to a kind of manufacture method of ferro-titanium.
Ferrotianium is the titaniferous that obtains through reduction or remelting at 20%～75% iron and titanium master alloy, is mainly used in steel-making (making reductor, alloying constituent and degasifier), industries such as casting and coating of welding electrode.
China iron alloy enterprise still continues to use traditional thermite process (also claiming perrin process) at present and produces ferrotianium, this technology be titanium magnet ore concentrate powder that roasting is good and aluminium powder, ferrosilicon powder according to certain ratio thorough mixing, light with magnesium and to carry out the reduction-oxidation titanium by self thermal source and obtain the low titanium ferrotitanium of titaniferous 25～45%.Thermite process only can production China current standards titaniferous 30% and the low titanium ferrotitanium of four trades mark of 40% two kind, but can not produce the high-titanium ferrotitanium of titaniferous about 70%, and the low titanium ferrotitanium of low Al, Si content.Because the thermite process nature of production has determined its higher impurity (Al 8～9.5%, and Si 3.0～5.0%, and Mn 2.5%).The steel-making later stage adds fashionable, is mingled with because of getting rid of to have increased in the steel, directly influences the quality of steel.Russian patent SU339701 discloses " production method of molybdenum-iron-titanium ternary alloy ", this method essence is with thermite process production " molybdenum-iron-titanium ternary alloy ", only titanium material is covered with the raw material of producing molybdenum-iron, fusing from top to bottom, with the scaling loss of minimizing titanium and the N content in the alloy, and this method is used to smelt ternary alloy, titanium content has only 40.17% in the alloy, smelt many drawbacks that ferro-titanium has thermite process equally with this method, can not produce the ferro-titanium of titaniferous about 70% certainly.
U.S. Pat 2776113 discloses " smelting the method for titanium alloy "; this method adopts consumable arc-melting process that titanium sponge is melted in the water cooled copper mould with electric arc furnace; under protection of inert gas, form titanium alloy ingot with even composition; for the processing of titanium material is supplied raw materials; this method need prepare consumable electrode; product cost is very high, and single preparation consumable electrode expense adds that the melting cost just equals the market price of ferro-titanium basically, and it is unlikely obviously producing ferro-titanium with this method.
The object of the present invention is to provide a kind of cost low, the titanium recovery rate height, environmental pollution is little, labor condition is good, be mingled with few, outward appearance and inner quality height, the manufacture method of ferro-titanium that particularly can any specification of quality of melting.
The present invention utilizes vacuum induction furnace, under vacuum condition or under the vacuum argon filling, can produce the ferrotianium of all size of titaniferous 20%～75%.The low titanium ferrotitanium impurity that vacuum induction furnace is produced is low, and this method can comprise the high-quality high-titanium ferrotitanium of titaniferous about 70% because of the ferrotianium that the difference that adopts raw material is produced desired various grades, and high-titanium ferrotitanium is owing to be the eutectic composition of iron-titanium alloy just in time, fusing point is low (1085 ℃, lower 342 ℃ than low titanium ferrotitanium), the proportion (5.4g/cm that suits
3), and the titaniferous height (in the molten steel add-on only be low titanium ferrotitanium 40%), foreign matter content is few, but uses saves energy in the steel-making, molten steel composition is even, reduced in segregation, the quality height of steel, and in vacuum induction furnace the melting ferrotianium, the titanium scaling loss is few, and flue dust is little, has improved environment and labor condition.
The present invention is a raw material to reclaim residual titanium or titanium sponge, the batching scope: residual titanium or titanium sponge or its two: 30%-80%, soft steel material 20%-70%, with by analysis, residual titanium after the fragmentation, oil removing, baking processing or titanium sponge or its two with the soft steel of proportioning in proportion, uniform mixing adds melting in the crucible of vacuum induction furnace.In order to prevent titanium and crucible reaction, select for use electrosmelted magnesite clinker or other more stable refractory materials to make crucible, under vacuum tightness≤66500Pa or vacuum argon filling≤66500Pa condition, energising is with titanium, iron fusing, after treating the even also calmness of liquid, pour in the ingot mould, cooling back vacuum breaker takes out, water-cooled, broken back barrelling.
The present invention compares with domestic and international existing ferrotianium production technique, has simple for processly, and cost is low, has reduced the scaling loss of titanium, titanium recovery rate is more than 95%, and environmental pollution is little, and labor condition is good, be mingled with few, outward appearance and inner quality height, ferro-titanium that particularly can any specification of quality of melting.The present invention has filled up the blank that China can not produce high-titanium ferrotitanium.
