Casting Quality Enhancement of Bushings Made of Foundry Aluminium Bronzes

Abstract

The paper is devoted to the establishment of the technology of castings manufacture out of multicomponent aluminium bronzes for oil and gas producing equipment. Aluminium bronze containing iron has been chosen as a material for casting manufacture. Founding into sand mixtures has been chosen as a manufacturing method. It has been shown that this type of founding allows obtaining the castings with minimal subsequent treatment and high quality surface. The use of the coke furnace at metal melting allows obtaining the castings with high performance characteristics due to gas protection of the melt.
