Technological possibilities and justification of electro-contact rapairing
Апстракт
This paper presents a selected repair technology for different types of electro-contacts by replacing the contact plates on the brass body of the electro-contacts and connecting the elements by process of brazing with silver solder. Quality assessment of the soldered connection was performed by metallographic examining of the structure soldered connection of the contact plates, hard brazing, and the body of the electro-contacts carrier. Determination of the exploitation period of the repaired electro-contacts is derived by comparison with new electro-contacts in industrial conditions. Analysis of economic and financial data is derived by comparing the costs of reparations and the cost of purchasing new electro-contacts annually in production conditions in the manufacturing Steel Plant - Smederevo. On the basis of investigation of the structure of the soldered connection, the exploitation period and analysis of economic and financial indicators, a feasibility assessment was given of the... applied technology of repair of electro-contacts in industrial conditions of the Steel Plant - Smederevo.
