Abstract
The utility model relates to a passage heating mantle for producing sponge titanium. A heat insulating material and fire bricks are arranged in a shell, resistance wires are connected in the fire bricks in a snakelike way, a post head is arranged on the shell; specially, the cross section of the fire brick is semicircular, the pore passage for arranging the resistance wires is a direct passage, the axes thereof is parallel with the axes of the fire bricks, namely, the axes of the passage; or the pore passage for arranging the resistance wires is semicircular, the plane of which is vertical to the axes of circular fire bricks, namely, the axes of the passage; the pore passage is directed to the axes direction of the fire bricks, that is, the passage direction is opened with a gap, the width of which is less than the diameter of the resistance wires, so as to lead the heat to be transmitted to the passage. As the pore opening is less than the diameter of the resistance wires, short circuit accidents caused by the resistance wires being deformed at high temperature and contacting with the passage can be avoided; stainless steel plates adopted by the inner layer of the shell can not be peeled and are durable in use. The nickel chromium wires are not crispy at high temperature, thus being suitable for dismounting and moving the passage frequently.
Description
Technical field:
The invention belongs to the technical field of smelting of non-ferrous metal, particularly produce titanium sponge and be used for the passageway heating mantles that vacuum distillation process connects process furnace and condensation stove.
Background technology:
The principle of produce titanium sponge by combination method is, need not lower the temperature after also original production finishes and tear stove open, directly changing distillation over to produces, direct commentaries on classics distillation production just needs a passage process furnace and two stoves of cool furnace is linked together, make that to need isolating product directly to be condensate in another reactor by high-temperature vacuum distillation in the process furnace be in the cool furnace, after the production cycle, distillment in the cool furnace just can directly hang in the process furnace and produce, shorten the production cycle, reduce production costs, guarantee the quality of raw material, so we design a passageway heating unit that satisfies these processing condition.
Summary of the invention
In order to realize this purpose, design a kind of passageway heating mantles that titanium sponge is used of producing, it is that insulation filler and refractory brick are set in housing, resistance wire is snakelike and is connected in the refractory brick, on housing, be provided with terminal stud, its special character is that the cross section of refractory brick is the hemicycle annular, the duct that resistance wire is installed is straight channel, the axis of its axis and annular refractory brick, the axis that is the passageway is parallel, the duct that resistance wire perhaps is installed is the hemicycle annular, the axis of its plane, place and annular refractory brick, it is the axis normal in passageway, the duct is towards the axis direction of refractory brick, be that the passageway direction has the breach of width less than the resistance wire diameter, so that heat conducts to the passageway.
Housing is a bilayer structure, and inside and outside layer is made by stainless steel plate, and resistance wire adopts nichrome wire (Ni20Cr80) or siderochrome niobium resistance wire.
The utility model is owing to hold the diameter of the duct opening of resistance wire less than resistance wire, can prevent from that resistance wire at high temperature is out of shape with the passageway to contact, and causes short circuit accident.Because the resistance wire duct that is installed in the heating mantles of the outside, vertical passageway is the hemicycle annular, resistance wire is the level of state, and the resistance wire duct that is installed in the heating mantles of the outside, horizontal passageway is straight channel, and resistance wire also is the level of state, and can prevent the softening length of stretching of resistance wire under the high temperature like this.The stainless steel plate that the housing internal layer adopts is not at high temperature peeled, and is durable in use.Nichrome wire does not become fragile through high temperature, and suitable passageway is often dismantled, moved.

Embodiment
A kind ofly produce the passageway heating mantles that titanium sponge is used, by outer 1 and the housing that constitutes of internal layer 2 in insulation filler 3 and refractory brick 4 and 6 are set, resistance wire 5 is snakelike and is connected in refractory brick 4 and 6, is provided with terminal stud 7,8 and 9 on housing.Because the passageway is made up of two vertical tubes and a transverse tube, so heating mantles forms by four, and two backs that are harmonious are identical with the passageway.Every heating mantles all is made of transversary F and vertical structure E, the shape of cross section of refractory brick is the hemicycle annular in two kinds of structures, but the duct shape difference of resistance wire is installed wherein, the duct 6.1 that resistance wire 5 is installed in the refractory brick 6 of the transversary F that cooperates with the passageway transverse tube is straight channel, the axis of its axis and annular refractory brick 6, the axis that is the passageway is parallel, and the duct 4.1 that resistance wire 5 is installed in the refractory brick 4 of the vertical structure E that cooperates with the passageway vertical tube is the hemicycle annular, the axis of its plane, place and annular refractory brick, it is the axis normal in passageway.Can guarantee any duct like this, promptly the resistance wire in transversary F and the vertical structure E all is in horizontality, avoids that resistance wire is in contact with one another under the high temperature, short circuit.The duct towards the axis direction of refractory brick, be that the passageway direction has the breach of width less than the resistance wire diameter, shown in sequence number 6.2,, and guarantee that resistance wire can not contact with the passageway so that heat conducts to the passageway, avoid the accident of being short-circuited.The internal layer of housing and skin are made by stainless steel, and resistance wire adopts nichrome wire (Ni20Cr80).
