Description
Technical field
The present invention relates to a kind of non-ferrous metal metallurgy equipment art, particularly a kind of reactor row magnesium chloride pipe making method that is used to produce titanium sponge.
Background technology
Titanium sponge is the primary raw material in the titanium alloy melting, and the main method of present industrial production titanium sponge is the Kroll method, and this method is at first to utilize Mg and TiCl
4Reduction reaction generate Ti, remove excessive Mg, reaction product MgCl by vacuum distilling then
2With a little amount of titanium muriate, obtain spongiform titanium at last and stick together.Reduction distil container is the key equipment in the whole production technical process; row's magnesium chloride pipe is the appurtenances of reduction distil container; bear the vital task of row's magnesium chloride between reduction period; in row's magnesium chloride process; row's magnesium chloride pipe working temperature can reach 800 ℃～840 ℃, after row's magnesium chloride finishes, need will arrange the sealing of magnesium chloride pipe transverse tube with blind plate; in order to shorten the blind plate settling time, water pouring with cold water earlier usually and directly will arrange and install after magnesium chloride transverse tube temperature is reduced to normal temperature.
CN1831163A " produces the reactor of titanium sponge " and discloses a kind of manufacture method of arranging magnesium chloride pipe, its weak point mainly is that row's magnesium chloride pipe transverse tube adopts the individual layer plain carbon stool to make, row's magnesium chloride transverse tube temperature can reach more than 700 ℃ during row's chlorination, easy oxidation attenuate, adding the welding of lower flange short cylinder and reactor shell restrains, row's magnesium chloride pipe transverse tube laterally is subjected to bigger thermal stresses effect, easy deformation not only, and the place that is connected with last lower flange short cylinder and reactor shell is easy to crack under the situation of expanding with heat and contract with cold, and causes the air admission reactor to pollute titanium sponge and causes substandard products even waste product.
In addition owing to row's magnesium chloride transverse tube is exposed in the normal temperature environment, heat radiation is very fast, in case discharging is not smooth, row's magnesium chloride transverse tube is easy to be chlorinated magnesium and magnesium stops up, in case occur stopping up, have to blowing out cooling is opened big lid and is severed row's magnesium chloride pipe, dredges, sometimes have to slice off whole row's magnesium chloride transverse tube and use new pipe again instead, this not only takies the plenty of time, has also increased meaningless power consumption, the more important thing is that degradation appears in quality product.
Summary of the invention
Technical problem to be solved by this invention provides a kind of row's magnesium chloride pipe making method that is used to produce titanium sponge, utilize row's magnesium chloride pipe of this method made, can improve the work-ing life of row's magnesium chloride pipe, shorten fault handling time, can guarantee titanium sponge production quality again, reduce production costs.
For the purpose that realizes solving the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of row's magnesium chloride pipe making method that is used to produce titanium sponge of the present invention, described row's magnesium chloride pipe is made up of closure plate, row's magnesium chloride transverse tube flange, row's magnesium chloride transverse tube, row's magnesium chloride vertical tube and row's magnesium chloride transverse tube inner sleeve, and gusset will be arranged the magnesium chloride vertical tube and reactor shell links together; Row's magnesium chloride transverse tube and reactor shell, row's magnesium chloride vertical tube and upward lower flange short cylinder continuous welding; Closure plate welds with row's magnesium chloride vertical tube at an angle, and its angle can be between 195～240 degree; Row's magnesium chloride transverse tube, row's magnesium chloride transverse tube inner sleeve, row's magnesium chloride transverse tube flange are formed row's magnesium chloride outlet pipe; Keep certain interval between row's magnesium chloride transverse tube and the row's magnesium chloride transverse tube inner sleeve.This gap can be between 2～30mm.
Described row's magnesium chloride pipe inside can be filled with aluminosilicate fiber cotton, can not fill yet, row's magnesium chloride transverse tube inner sleeve left part point is welded on row's magnesium chloride transverse tube, and does not weld the right part, and the row's of assurance magnesium chloride transverse tube inner sleeve Shi Yiduan that is heated can stretch.
By above-mentioned connection, gusset will be arranged the magnesium chloride vertical tube and reactor shell links together, and assurance is arranged both can compatible deformation.Row's magnesium chloride transverse tube reactor shell, row's magnesium chloride vertical tube and upward lower flange short cylinder continuous welding are guaranteed air tight.Closure plate welds with row's magnesium chloride vertical tube at an angle, stops up in case row's magnesium chloride vertical tube is connected corner with row's magnesium chloride transverse tube, is convenient to dredge with iron bar.
These technical schemes comprise that improved technical scheme also can make up mutually or combination, thereby reach better technique effect.
By adopting technique scheme, the present invention has following beneficial effect:
1, row's magnesium chloride transverse tube adopts two-layer sleeve pipe to form, the outer external world and the reactor of guaranteeing seals, internal layer contacts with melt in row's magnesium chloride process, because there is certain clearance in inside and outside cover sleeve pipe, the row's of making magnesium chloride transverse tube temperature is very low, and thermal stresses reduces, and has avoided row's magnesium chloride transverse tube weld seam to break, inner layer sleeve can freely stretch in addition, has prolonged inner layer sleeve work-ing life.
2, the place that is connected with vertical tube of row's magnesium chloride transverse tube, the vertical tube top is a tilted mouth shape, in case the junction is stopped up, can dredge pipe anyhow with iron bar.
3, because the inner sleeve point is welded on row's magnesium chloride transverse tube,, stops up when being difficult to dredge by row's magnesium chloride pipe transverse tube in case taking place, can the row of severing magnesium chloride transverse tube, and take out the inner sleeve of obstruction and can dredge, avoided the blowing out processing of uncapping, guaranteed quality product greatly.
4, because the heat-insulation and heat-preservation effect of row's magnesium chloride transverse tube inner sleeve is discharged in the magnesium chloride process, and melt is difficult for heat radiation, reduced the blocking probability of row's magnesium chloride pipe.
