Magnesium reduction process is the main method of current industrial production titanium sponge, and its main chemical reactions is：TiCl4+ Mg=
Ti+MgCl2+ Q, the reduction process are the key links of titanium sponge production, and vital work is played to the quality of final products
With.Substantial amounts of heat can be produced in reduction process, if unnecessary heat can not discharge in time, conversion zone temperature mistake can be caused
Height, influence the titanium structure and chemical index of titanium sponge.
To ensure that heat caused by reduction can discharge, it is necessary to be aerated cooling to titanium sponge reduction stove in time.It is existing
Some reduction furnaces are provided with as shown in figure 1, the main body of heater 2 and reactor 4 for including coaxial package between body of heater 2 and reactor 4
Cooling air channel 3, top air outlet 5 and cold wind mouth 6 are respectively equipped with upper and lower end of the reduction reaction with H portions.By free convection or
Forced convertion enters cold air in burner hearth from cold wind mouth 6, then the top air-out for the reaction zone H upper ends setting for passing through reduction furnace
Heat dissipation into external environment condition, so as to take away the heat of the outer wall of reactor 4, is ensured reduction reaction in suitable temperature by mouth 5
In the range of.
The mode directly discharged causes the waste of amount of heat, does not meet the hair that modern enterprise is energy-saving, green
Exhibition theory, and large effect is caused to operating environment, especially heat period operation.Magnesium heat system is related in the prior art
The waste-heat recovery device of standby titanium sponge, is largely to be introduced into by pipeline in heat exchanger, with other media, such as water, enters
Row heat exchange, then applies hot-water collection, and this method one side heat exchange efficiency is low, on the other hand the waste heat application site away from
It is general from the production site of titanium sponge farther out to draw waste heat or heat exchange medium, it is necessary to lay pipeline, increase cost of investment, drop
Utilization rate low in calories, pipe laying can also increase the in disorder of place, certain potential safety hazard be present.
The content of the invention
It is existing remaining to solve it is an object of the invention to provide the residual neat recovering system that a kind of magnesiothermy prepares titanium sponge

To achieve the above object, waste heat is directed directly to waste heat recovery terminal by the inventive method, and the waste heat recovery terminal can
To be arranged in the side that magnesiothermy prepares sponge titanium eguipment, the terminal is placed with the incubator of magnesium ingot, using waste heat by magnesium
Ingot toasts drying, and it is low on the one hand need not to set up too long of pipeline, cost of investment, another aspect waste heat direct baking magnesium ingot, changes
The thermal efficiency is high, and the magnesium ingot after baking can be directly used for the production of titanium sponge.Specifically, the exhaust heat recovering method is gone out using reduction furnace
The high temperature air of air port discharge, comprises the following steps：
A, arranged in the incubator provided with walking mechanism magnesium ingot to be baked, sealing, and by incubator be pushed into it is described also
It is former stove side, spacing；
B, the blast pipe of incubator bottom is connected with the pipeline of the reduction furnace air outlet, opening is arranged on blast pipe
Valve, the magnesium ingot in high temperature air and incubator carries out heat exchange, finally from the discharge pipe discharge at the top of incubator；
C, after toasting magnesium ingot 4-6 hours, pipeline is dismantled, incubator pushes, then by the pipe of the reduction furnace air outlet
Road connects another incubator for being placed with magnesium ingot to be baked.
Preferably, the residual neat recovering system that the above method uses, is arranged on reduction furnace air outlet side, the waste heat recovery
System includes the incubator provided with walking mechanism, and the air intake being connected with the pipeline of reduction furnace air outlet is set in the bottom of incubator
Pipe, the discharge pipe emptied is set at the top of incubator；The orifice plate of arrangement magnesium ingot is provided in the incubator.
Preferably, the one side of the incubator is provided with hermatic door, and the orifice plate is horizontally disposed with 2-5 layers.
The spacing of adjacent layer orifice plate is 2-5 layers magnesium ingot height.
The magnesium ingot close-packed arrays and alternately reserves ventilative interval on orifice plate on the left side of adjacent layer orifice plate or right side,
Form the high temperature air structure that cross-current type rises from bottom to top.
Or ventilative gap is left between adjacent magnesium ingot, high temperature air is formed through between the through hole and magnesium ingot on orifice plate
The tortuous structure risen in gap.
Magnesiothermy titanium sponge production must toast drying before requiring raw materials used magnesium ingot use, can shove charge use, it is existing
Titanium sponge production enterprise takes substantially to be placed on magnesium ingot in incubator, and magnesium ingot is dried in the method baking for being passed through high-temperature steam, this
Enterprise is required to have steam throughout the year, enterprise must configure steam storage delivery system, but some middle-size and small-size sponges
Titanium enterprise can not just meet this requirement.Taken full advantage of nearby in above-mentioned technical proposal caused remaining during titanium sponge production
Heat, the structure of incubator is simple, can circulate, be used continuously.
The inventive method has the following advantages that：(1) present invention effectively solves no steam feed system enterprise to magnesium ingot
