Description
Technical field
The present invention relates to a kind of smelting process of metal, especially a kind of working method that adopts the high ferrotianium of 70# of high pressure resistant high temperature resistant reaction stove.
Background technology
As everyone knows, the high ferrotitanium alloy of titaniferous 65% ~ 75% is the important source material that the steel-making industry is used for smelting all kinds of special steels and steel alloy owing to have suitable proportion and lower fusing point always.Therefore the production of high ferrotianium also is the hot subject of The ferroalloy industry research always.
The method of at present, producing high ferrotianium mainly contains two kinds: remelting process and perrin process (being metallothermics).Remelting process is to be raw material with useless titanium material, in the electric furnace under open type or the vacuum state, adds the iron remelting, is cast into high ferrotianium ingot after the slagging-off.The advantage of this method is that Composition Control is accurate, and technology is simple, and titanium recovery rate is high, and the product oxygen level is low.For example: one Chinese patent application number: 96117080.8, this Invention Announce a kind of open type electric furnace remelting method of producing high ferrotianium.The shortcoming of remelting process is that a large amount of purchases of useless titanium material are had any problem, and the production cost of useless titanium is very big with the fluctuation of pure titanium price, and then cost is too high to adopt pure Titanium Sponge 40-60 mesh, is difficult to meet the need of market.Perrin process employing rutile is a main raw material, and aluminium powder adds VAL-DROP (or Potcrate) as heat-generating agent as main reductive agent, adds lime and/or fluorite as production high ferrotitanium alloys such as slag formers.It is wide that this method has raw material sources, low price, and production cost is little with pure titanium price volalility, can produce in enormous quantities.Although the high ferrotianium titanium content that traditional perrin process is produced has reached more than 70%, oxygen level is very high, and generally about 8 ~ 12%, this high ferrotianium is tested through steelworks, can't from molten steel, receive titanium elements.Domesticly also study reducing high ferrotianium oxygen level; For example: Chinese patent numbers 201010514572.3 has been announced and a kind ofly on the basis of traditional perrin process, has been adopted the calcium-magnesium alloy reductive agent to carry out for two steps to strengthen reductive technology, obtained oxygen level at the high ferrotianium below 1%.But this method need be carried out the smelting of two steps, and high-temperature fusant is poured the careful safety features of manipulation require of the crucible that fills calcium-magnesium alloy, technology relative complex into.
Summary of the invention
To the deficiency among the high ferrotianium preparation technology of present traditional perrin process, the invention provides a kind of HTHP and rock the method that metallothermy under the condition prepares high ferrotianium, solve the outer legal system of present traditional burner and be equipped with the problem that there is too high oxygen level in high ferrotianium.
Technical scheme of the present invention is achieved in that
A kind of perrin process is produced the method for the high ferrotianium of 70#, comprises starting material preparatory process, smelting procedure and separates finishing procedure.
(1) said starting material preparatory process: select required starting material to carry out technological preparation, comprise the oven dry of rutile, concentrated ilmenite, reductive agent, VAL-DROP, slag former, bake out temperature is 120 ℃ ~ 250 ℃, and the furnace charge of oven dry is uniform mixing in proportion;
(2) said smelting procedure: mixed furnace charge pack into one can the high-temperature-resistant high-pressure-resistant Reaktionsofen of control pressure in; Spread an amount of magnesium powder at the compound top, the sealing bell is fixed in airtight Reaktionsofen on the rocking equipment that can produce vertical plane then; The mode of the electricity consumption sparking magnesium powder that ignites outside stove; Start and smelt reaction, start rocking equipment in the reaction process, and control furnace pressure between 1MPa ~ 20MPa through the purging valve on the Reaktionsofen; Stop after reaction in furnace finishes shaking and exhaust is put and is depressed into normal pressure, and be cooled to room temperature;
(3) said separation finishing procedure: open Reaktionsofen and take out the slag gold bullion that said smelting procedure produces, it is broken apart to carry out the slag gold, and separating obtained metal block carries out broken finishing can obtain the high ferrotianium of 70#.
Further preferred: the size range of said rutile and concentrated ilmenite is 80 order to 200 orders, and the size range of slag former is 20 order to 40 orders.
Further preferred: said reductive agent is one or more the combination in aluminium powder, aluminium calcium powder and the magnesium powder, and the granularity of reductive agent powder is greater than 20 orders.
Further preferred: the mixing of said rutile, concentrated ilmenite, reductive agent, VAL-DROP, slag former is respectively by mass ratio: 70 ~ 85:10 ~ 25:40 ~ 60:10 ~ 20:3 ~ 6.
Further preferred: said slag former is one or both the combination in lime and the fluorite.
The method that a kind of perrin process of the present invention is produced the high ferrotianium of 70#: the closed environment of the controllable high-voltage confined reaction stove of the band rocking equipment of employing makes the lost significantly reduction of the heat of reduction reaction, can reduce the amount of allocating into of heat-generating agent VAL-DROP and reductive agent, saves cost; Airtight environment still is enclosed in the system material that splashes in the reaction process, and high ferrotianium yield is improved; Rocking that rocking equipment produces makes sufficient reacting carry out, and the slag gold separates fully, and high ferrotianium yield improves, and oxygen level descends; The combination of aluminium powder, aluminium calcium powder and magnesium powder makes that aluminium content reduces in the reaction product, and oxygen level reduces; Compare with traditional perrin process, reaction process does not have dust to produce, and has saved dust removal installation; Because the high temperature hold-time in when reaction is long, sedimentation is abundant, and the golden separator well of slag has been created good condition for next step operation, has reduced cost; In order to prevent the pressure rising overpressure scope of design in the airtight reaction under high pressure stove, the automatic pressure relief valve on the Reaktionsofen plays the effect of SV through venting adjustment internal pressure.
