The female silk attachment means of metal iodide purified reaction stove electrode
Technical field
The utility model belongs to purification of metals device technique field, connects dress particularly to the female silk of metal iodide purified reaction stove electrode
Put.
Background technology
Iodate method of purification is mainly used in the purification of Titanium, zirconium, hafnium, for remove in metal not with Iod R or generate not
Gaseous impurity in the impurity element that the iodide of volatilization and iodide at high temperature do not decompose, and reduction metal plays effectively
Refining effect.The general principle of iodate method of purification is to arrange two warm areas in vacuum reaction stove, i.e. one low-temperature space (iodate
District) and a high-temperature region (resolver or crystallizing field), iodine steam reacts at low-temperature space and raw material and generates volatile iodide,
Iodide resolve into metal and iodine steam in high-temperature region, and metal deposit, on red-hot female silk, makes heated filament grow up, and iodine steam returns
Raw material district continues to react with raw material, reaches the purpose purifying.
The temperature control that it is critical only that low-temperature space (iodate district) and high-temperature region (resolver or crystallizing field) of iodate method of purification, low
Warm area (iodate district) is mainly by the temperature of Heating Furnace Control raw material, and high-temperature region (resolver or crystallizing field) then uses connection electricity
Female silk of pole, by changing size control female silk temperature realization of electric current, voltage.The factor of the female silk temperature of impact mainly has iodate
The connected mode of electric current, iodate voltage, the material of female silk, diameter and the female silk of electrode.Female silk temperature control directly affects iodate
Thing generating rate, the speed of metal deposit and deposition quality, and then affect the refining effect of metal.
At present, the connected mode of the female silk of iodate purifying plant electrode mainly has: (one) uses welding manner directly to connect mother's wire bond
On iodate device metal electrode, this connected mode is the more commonly used mode of current iodate method of purification.The shortcoming of this mode exists
In iodate crystallization rod with electrode growth together with, cause when coming out of the stove iodate excellent dismantle from electrode relatively difficult, bothersome arduously,
Need many people compounding practice, and easily cause the damage of metal electrode.(2) on metal electrode, processing meets dimensional requirement
Female for iodate silk is passed through metal electrode and fixes at the other end, by outside tightening nuts, mother's silk being tightened to electricity by circular hole
Extremely go up.The shortcoming of this mode is that course of iodization can make the circular hole of metal electrode block, and causes metal electrode not reuse,
To re-work new metal electrode every time, cause the increase of iodate cost;And use this electrode connection mode to assemble not
Local current can be caused well excessive and cause fracture of wire, production efficiency is low.(3) use metal molybdenum filament that mother's silk and electrode are bundled in one
Rise.This mode shortcoming is that female silk electric conductivity is relatively poor, easy fracture of wire, and the same with welding, final products crystallization rod
With electrode separation difficulty;And after product crystallizes rod and electrode separation, it is also necessary to by the termination excision with molybdenum filament, cause product
Waste.
