Abstract
Using models the possibility of repair of worn-out flat panels of machines of continuous casting of billets (MCCB) moulds by autovacuum brazing of restoration copper layer was tested. The brazed joint was produced between two copper plates without defects in the form of pores and cracks. The tensile strength of copper brazed joint for separation between layers was investigated, and also the bend tests were performed. Thermal resistance of the brazed joint was evaluated. The obtained results allow the method of autovacuum brazing to be recommended for repair of flat panels of the moulds. 12 Ref., 6 Figures.
