目前工业生产用铝电解槽的阴极都是由炭块和钢棒组合而成的炭块组构成的。炭块和钢棒之间一般都采用高磷生铁联结,有的则用炭糊联结。我厂为了提高槽底的使用寿命和降低槽底·电压降,曾在生产的两个系列中,第1系列用炭糊联结的24台,用生铁联结的48台;第2系列用炭糊联结的和 At present, the cathode of an aluminum electrolytic cell for industrial production is made up of a carbon block group formed by a combination of a carbon block and a steel bar. Carbon blocks and steel rods are generally used high-phosphorus pig iron connection, while others use carbon paste connection. In order to increase the service life of the bottom of the tank and reduce the voltage drop at the bottom of the tank, I plant in the two series produced in the first series of 24 with carbon paste linked to 48 pig iron linked to the second series with carbon paste The combined and
