Rehabilitation of Mini-furnace in the Foundry Workshop

Abstract

The rehabilitation of mini-furnace in the foundry workshop is undertaking. The mini-furnace assembly among other things has five main components which include; the furnace shell, the refractory lining [wall of the furnace]. The burner and its pipe, full tank scraps. Full tank and crucible pot. The furnace body is enclosed in cylindrical metal sheet measuring 575mm diameter by 500mm high it is lined internally with superior refractory bricks of 65mm thickness. The furnace by calculation has these specifications; circumstance of 942.86mm volume of 0.04m^3, weight of 49.05KN. The melting process is done in a crucial rammed externally with fire-clay and made from heat resistance sheet at temperature of 700^0 C to 800^0 C. An air-blast from electrically powered centrifugal blower is atomized with condemned diesel oil which flows down by gravity and is controlled by throttle valve in the fuel line and form the heat source when they mixed inside the combustion chamber.
