Shape shape mold in cast anode plate, and with cathode plate intersects placement logical direct current is electrolysed in a cell, on anode
Metal and the active impurity element of Bi Qi oxidation dissolution occurs and enters solution, it is heavy that refined metals element then restores on cathode plate
Product, obtains the higher cathode product of purity.
The continuous oxidation dissolution of metal and other active metals enters solution on anode plate, and inactive element can remain in
On pole plate or part deposits to slot bottom and forms the earth of positive pole.The electrolysis process requirement of reasonable economic indicator is maintained to protect in electrolytic process
A certain amount of anode scrap is stayed to return in smelting furnace together with new raw material melting again, be cast into anode into next electrolysing period.
The uniformity of anode plate is to guarantee that electrorefining processes obtain high quality cathode product, uniform current distribution, low product direct current
An important factor for power consumption and the low anode scrap rate of recovery, and anode plate thickness is one of the main parameter controlled in casting process.

Set, specifically include: the data measured according to the range unit establish the change curve of measurement distance and time；According to described
Occur indicating in change curve gap between two molds apart from spike, the top edge distance of mold cavity and mold cavity
Bottom surface distance determines that the mold cavity on casting machine reaches the casting position；
When the mold cavity reaches the casting position, stop casting machine operation, and pour into the mold cavity
Cast high-temperature liquid state anode melt；
When the mold cavity reaches the casting position, and the survey when data and casting of measuring device measurement
When the difference of data away from device measurement reaches Thickness of Copper Positive Plate preset value, stop casting；
The Thickness of Copper Positive Plate preset value is calculated by following formula:
Wherein, T is anode melt temperature, γ is anode fusant density, η is anode melt viscosity, δ is casting gate and mold
Height between type chamber, a, b, c and d are constant factor.
The non-contact distance measurement device includes any in laser range finder, ultrasonic range finder and X-ray rangefinder
One kind, or the rangefinder array being made of them.
The method of anode plate quantitative casting provided by the invention accurately controls casting die by non-contact measurement mode
The thickness of Anodic melt, so that the quality of positive plate casting be greatly improved, not only realize to nickel electrowinning anode and
Copper, lead, tin etc. refine the casting of anode, but also the generally applicable Metal Production that other need to be electrolysed using casting anode
Process.The present invention is due to the contactless measurement using separate high temperature, so that the manufacture and control of casting system obtain greatly
Amplitude simplifies, and maintenance cost is greatly reduced, and improves the control precision of Nickel Anode Plate casting significantly.
