Description
Technical field
The present invention relates to non-ferrous metal metallurgy, produce the method for titanium sponge in particular to the magnesium method.
Background technology
The process that the magnesium method is produced titanium sponge is that titanium tetrachloride is added reactor, uses magnesium metal reduction, and distillation makes titanium sponge after purifying.Its reduction process prior art is the liquid titanium tetrachloride under the normal temperature directly to be added in the reactor with liquid metal magnesium in the reactor by feeding tube contact, and carries out reduction reaction.Titanium industrial expansion direction is the maximization of single furnace output, under the bigger situation of reactor capacity, reactor temperature can be up to 800～920 ℃, the reinforced reactor middle part that enters of titanium tetrachloride, most of titanium tetrachloride can be gasified and be reacted rapidly with melt metal magnesium, restores titanium; To add speed fast but because of titanium tetrachloride, the titanium tetrachloride of some liquid phase fails to gasify, MAGNESIUM METAL generation vigorous reaction with regard to direct and reactor center position, titanium tetrachloride and magnesiothermic reduction reaction are strong exothermic reaction, heat row do not go out and will cause in this position reduction heat quantity set, this position titanium sponge Yin Gaowen and sintering, thus make the stick together density of center titanium sponge product of titanium sponge higher.Reactor capacity is big more, and the reactor heat-sinking capability is poor more, and is serious more in the reduction heat quantity set.
This prior art charging process brings following consequence:
(1) distills when purifying after reduction finishes,, reduce excessive magnesium and remaining impurity such as magnesium chloride and be difficult to remove, influence quality product because of agglomerating titanium sponge compact structure;
(2) agglomerating titanium sponge compact structure, broken difficulty is difficult to be crushed to the granularity that product index is stipulated;
When (3) user uses this titanium sponge to produce the titanium ingot with vacuum arc fumace, be difficult to make electrode,, easy fracture, short circuit when the melting ingot casting, burn out crucible even made electrode, even the accident of blasting.
The inventor once applied for patent of invention, and application number 200610051187.3 " a kind of magnesium method is produced the titanium tetrachloride atomising method of titanium sponge " solves this difficult problem, and certain effect is arranged.
Summary of the invention
Purpose of the present invention just is to provide the charging process of the titanium tetrachloride gasification that a kind of magnesium method produces titanium sponge, after earlier titanium tetrachloride fully being gasified, titanium tetrachloride is entered in the reactor with gaseous form carry out reduction reaction with magnesium again, reduction reaction is carried out in reactor comparatively equably, solve the heat accumulation problem of magnesium reduction titanium tetrachloride effectively, improve the density of titanium sponge and the quality of raising titanium sponge.
For solving this difficult problem, the physicochemical property that the contriver produces the structure of reactor characteristics of titanium sponge and material to the magnesium method are studied and are thought deeply, through overtesting, invented charging process with the titanium tetrachloride gasification, the invention reside in before titanium tetrachloride carries feeding tube to enter reactor and be provided with heating unit outside, liquid titanium tetrachloride is through outside this during heating unit, be heated to the above and gasification of boiling temperature, join in the reactor through the titanium tetrachloride filling tube, gasiform titanium tetrachloride and molten metal magnesium uniform contact are carried out reduction reaction again.The invention provides a kind of device of titanium tetrachloride gasification, promptly outer heating unit: before titanium tetrachloride carries feeding tube to enter reactor, be provided with heating unit outside, should comprise outer cylinder body, shrouding, inner barrel and heating unit and flame-proof thermal insulation material by outer heating unit, described outer cylinder body two ends are provided with shrouding, in outer cylinder body, be provided with an inner barrel, being provided with heating unit, between heating unit, outer cylinder body and inner barrel, flame-proof thermal insulation material is arranged near the inner barrel place.During production, liquid titanium tetrachloride is at this heating unit of process, be heated to boiling temperature above (boiling point of titanium tetrachloride is 136.2 ℃) and gasified, join in the reactor through the titanium tetrachloride filling tube again, thereby realize that reduction reaction carries out comparatively equably in reactor.
Magnesium method of the present invention produces the charging process of the titanium tetrachloride gasification of titanium sponge, overcome liquid titanium tetrachloride in the prior art at reactor center position and MAGNESIUM METAL vigorous reaction, influence the difficult problem of titanium sponge quality; Titanium tetrachloride gasification back adds, and the reduction reaction in the reactor is carried out equably, has alleviated the heat accumulation problem of original technology, thereby has guaranteed the quality product of titanium sponge.
The present invention is applicable to the producer that adopts the magnesium method to produce titanium sponge.

Accompanying drawing 1 is a titanium tetrachloride gasification charging process synoptic diagram of the present invention.
Among the figure, 1 is the titanium tetrachloride filling tube, and 2 is reactor, and 3 is MAGNESIUM METAL, 4 gaseous titanium tetrachlorides for reinforced mouth of pipe place, and 5 is outer cylinder body.6 is shrouding, and 7 is inner barrel, and 8 is flame-proof thermal insulation material, and 9 is heating unit.
Embodiment
Embodiment
In certain titanium sponge factory, adopt the magnesium method to produce titanium sponge.Reactor 2 is packed in the process furnace, and the MAGNESIUM METAL 3 in the reactor 2 is molten state.As shown in Figure 1, heating unit outside before entering reactor 2, titanium tetrachloride filling tube 1 is installed.Should comprise outer cylinder body 5, shrouding 6, inner barrel 7 and heating unit 9 and flame-proof thermal insulation material 8 by outer heating unit, described outer cylinder body 5 two ends are provided with shrouding 6, in outer cylinder body 5, be provided with an inner barrel 7, being provided with heating unit 9, between heating unit 9, outer cylinder body 5 and inner barrel 7, flame-proof thermal insulation material 8 is arranged near inner barrel 7 places.During production, the titanium tetrachloride of the liquid phase that enters from header tank through should outside during heating unit, be heated to the above and gasification of boiling temperature, in titanium tetrachloride filling tube 1 joins reactor 2, carry out reduction reaction again, produce titanium sponge and liquid magnesium chloride with MAGNESIUM METAL 3, thereby the realization reduction reaction is carried out in reactor comparatively equably, as shown in Figure 1, the gaseous titanium tetrachloride 4 at reinforced mouth of pipe place for reinforced mouth of pipe place, titanium tetrachloride enters in the reactor with gaseous form.
The liquid magnesium chloride is discharged out, and titanium sponge then carries out vacuum distilling, removes excessive magnesium of reduction and residue magnesium chloride, and is broken again, obtains the titanium sponge product.
