Abstract:
The invention relates to a method of providing an electric current taker (6a, 6b) made from silver and having a highly electro conductive contact surface into an aluminium support bar (1) to be used in electrolysis. In order for the support bar (1) and the electric current taker (6a, 6b) there into be easily, quickly and inexpensively manufactured,the method comprises a) heating a first end (2) of the support bar (1) and providing on top of it a solder containing a substance whose affinity to oxygen is high after a temperature of an aluminium surface is at a temperature which exceeds a melting temperature of the solder, whereby the solder is spread in a molten state on top of the surface, b) breaking an aluminium oxide layer between the aluminium and the molten solder by a mechanical treatment so that oxygen is released from the aluminium oxide layer, the oxygen reacting with the substance of the solder having a high affinity to oxygen and forming, together with the substance, on the surface of the molten solder an oxide layer, and c) providing, on top of the solder, the electric current taker (6a, 6b) and letting the solder to solidify and the electric current taker to become attached to the solidified solder. The invention further relates to a support bar (1).
Abstract:
The invention relates to a method of providing an aluminium conductor rail (1) used in electrolysis with a silver electric current supplier (6a, 6b, 6c) having a contact surface that conducts well electricity. In order for the conductor rail (1) and the electric current supplier (6a, 6b, 6c) thereof to be economical, easy and rapid to manufacture, a) the material selected for the conductor rail (1) is a aluminium-based alloy, b) the surface of the conductor rail (1) having an aluminium surface is heated and once the surface of the aluminium reaches a temperature exceeding the melting temperature of the solder, a zinc-based solder is arranged on top of it, the solder containing a substance with high affinity to oxygen and the solder being then spread in the molten state onto said surface, c) an aluminium oxide layer formed between the aluminium and the molten solder is broken by a mechanical treatment so that oxygen is released from the aluminium oxide layer, the oxygen reacting with the substance of high affinity to oxygen and forming together with said substance an oxide layer on the surface of the molten solder, and d) an electric current supplier (6a, 6b and 6c) is arranged on top of said solder, the solder is allowed to solidify and the electric current supplier to attach in place into the solidified solder. The invention also relates to a conductor rail (1).
