Description
Technical field
The present invention relates to a kind of non-ferrous metal metallurgy equipment art, particularly a kind of device that is used to produce the high porosity Titanium Sponge 40-60 mesh.
Background technology
Titanium Sponge 40-60 mesh is the primary raw material in the Ti alloy, and it is the Kroll method that the main method of producing Titanium Sponge 40-60 mesh is gone up in industry at present, and this method is at first to utilize Mg and TiCl
4Reduction reaction generate Ti, remove excessive Mg, reaction product MgCl through vacuum distilling then
2With the little amount of titanium muriate, obtain spongiform titanium at last and stick together.
Large-scale 10 tons of reduction and distillation furnaces are main type of furnaces that the Kroll method is produced Titanium Sponge 40-60 mesh, but the Titanium Sponge 40-60 mesh produced of this type of furnace exists that center local superheating, spongeization rate are low, the densification of titanium piece is difficult to broken problem aborning.And be the important behave of the local agglomerating in center that sticks together of current domestic and international minimizing titanium through changing feed way.In please number be that 200620133754.5 Chinese patent has been introduced the titanium tetrachloride gasification installation that a kind of magnesium method is produced Titanium Sponge 40-60 mesh, this device ultimate principle is to react uniformly with magnesium after utilizing the heat of molten metal bath magnesium that titanium tetrachloride is fully gasified again.Though the alleviation to a certain degree of this utility model liquid titanium tetrachloride at reactor center position and MAGNESIUM METAL 99 vigorous reaction, help the raising of the quality product of Titanium Sponge 40-60 mesh, still have following problem in actual use:
(1) necessarily expects under the fast situation,, TiCl can not be provided because the heat transfer time is short
4The required heat that is gasified totally, so gasification degree is low;
(2) feeding device partly is inserted in the Mg melt, adds the rising of liquid level in the reinforced process, and the titanium piece that the filling tube pore volume is prone to generated stops up;
(3) feeding device is near the reaction zone central position, and the filling tube end can be melted, and not only causes the Fe content overproof, and has lost gasification result.
Therefore this utility model acquires a certain degree of difficulty in reality is promoted.
Application number is the titanium tetrachloride charging process that a kind of magnesium method that 200610051291.2 Chinese patent relates to is produced Titanium Sponge 40-60 mesh in addition; The ultimate principle of this method is: before titanium tetrachloride carries feeding tube to get into reactor drum, 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 drum through the titanium tetrachloride filling tube, gasiform titanium tetrachloride and molten metal magnesium uniform contact are carried out reduction reaction.Though adopt this method that titanium tetrachloride is fully gasified, a significant drawbacks is arranged, be exactly because TiCl
4Being gasified totally needs a large amount of heat, and adopts the actual heat radiation load that has increased Reaktionsofen of external heat source gasification titanium tetrachloride, under the certain situation of heat radiation load, has not only increased energy consumption, has also limited the raising of material speed, has prolonged reduction cycle.
Application number is the titanium tetrachloride atomising method that a kind of magnesium method that 200610051187.3 Chinese patent relates to is produced Titanium Sponge 40-60 mesh; Wherein mention and utilize swirl nozzle formation mist droplet to be ejected on the MAGNESIUM METAL 99; Carry out reduction reaction, after this patent thought that titanium tetrachloride atomizes, the reduction reaction in the reactor drum was carried out equably; The situation of heat accumulation can not occur, thereby guarantee the quality product of Titanium Sponge 40-60 mesh.But in the actual use of this patent, only use swirl nozzle not scatter fully by titanium tetrachloride, and because the resistance of nozzle and pipeline expect that the fast upper limit receives than limitations.
Summary of the invention
