Abstract
The utility model relates to an 80 KA minitype prebaked anode aluminum electrolyzer cathode carbon block, steel bar grooves used to produce the cathode carbon block groups are arranged on the carbon block, the characters are that the cathode carbon block groups are connectivity structure,and the steel bar grooves on the carbon block are paratactic double-grooves. After the application of the 80 KA minitype prebaked anode aluminum electrolyzer cathode carbon block, the voltage of the hearth is reduced more than 300 MV, the voltage of the average groove is reduced lower than 4.20 V which has been improved, the current efficiency reaches 91.5%, increasing by 1-2%, while achieving a more advanced coke preheating, and a no effect start technology, the baking start voltage is reduced to 4.8-5.0 V from the original 7.5-8.0 V; during the baking, the voltage is reduced to 2 .28-2.30 V from the original 2.78-2.8 V, the voltage of electricity baking is reduced 500 MV, each electrolyzer can save electricity 9024 KWh for the purpose of energy saving, and the corrosion and the thermal impact from the aluminum-water and the high temperature electrolyte during the early start are alleviated.
Description
Technical field
The utility model relates to a kind of improved 80KA small pre-calcining anode aluminium cell cathode carbon pieces, is applied on the 80KA small pre-calcining anode aluminium cell.
Background technology
At present on China's small aluminium electrolytic cell, adopt the cathode carbon pieces group of two kinds of specifications that length is complementary more, the assembling that matches, adopt cold smash stick with paste prick solid or bonding with caking agent; Because the congenital defect of cathode carbon pieces group on aluminium cell of long and short two kind specification, construction quality is difficult to further raising, influence the work-ing life of electrolyzer, in the electrolysis production process, the furnace bottom volts lost is high, good production specifications are difficult to guarantee, influence the current efficiency of electrolyzer, influence electrolysis production and cause unfavorable factor thereby become.
Summary of the invention
The purpose of this utility model is to provide a kind of improved 80KA small pre-calcining anode aluminium cell cathode carbon pieces, can improve the construction quality of aluminium cell, reduces the volts lost of aluminium cell furnace bottom, improves current efficiency, prolongs the work-ing life of electrolyzer.
80KA small pre-calcining anode aluminium cell cathode carbon pieces described in the utility model, charcoal piece are provided with the steel bar trough of making the cathode carbon pieces group, and its cathode carbon pieces is the entire body structure, and the steel bar trough on the charcoal piece is a double flute arranged side by side.Form the entire body dual-slot structure, the cathode carbon pieces of promptly former long and short two kind specification unites two into one, and length has side by side two for both and head joint sum, steel bar trough, and employed rod iron is four of biserials.
After the 80KA of applicant unit small pre-calcining anode electrolytic tank is used, the furnace bottom volts lost reduces more than the 300mv, average cell voltage drops to below the 4.20V after the improvement, current efficiency reaches 91.5%, improve 1-2%, simultaneously, realized comparatively advanced baking coke particles, the effect-less starting technology, roasting and starting voltage is reduced to 4.8-5.0V by original 7.5-8.0V, voltage is reduced to 2.28-2.30V by original 2.78-2.8V during the roasting, electrical roasting loss of voltage 500mV, thus much one, every electrolyzer 9024KWh that can economize on electricity reaches energy saving purposes, has also alleviated the permeating corrosion and the thermal shocking of roasting and starting initial stage aluminium water and high-temperature electrolysis confrontation cathode carbon pieces.Facts have proved that the application of this technical project to improving the construction quality of aluminium cell, prolongs electrolyzer work-ing life, stablize the electrolyzer technical qualification, reduces the volts lost of aluminium cell furnace bottom, raising current efficiency has played positive pushing effect.
The physical and chemical index of the utility model cathode carbon pieces sees the following form:
