| Summary |
"A thesis giving the details of construction of a rotating induction furnace and its use to experimentally determine the amounts of copper absorbed in high-iron and low-iron slags at various temperatures. A rotating induction furnace is advantageous for slag study in that the slag is contained in a molten pure metal cup and does not come in contact with any refractory, which would be attacked by the slag and contaminate it. The molten pure metal cup is formed by melting the pure metal in a refractory crucible and spinning this inside an induction coil. The induction coil supplies heat for melting both the pure metal and slag, and this type of heating also facilitates close temperature control. The rotating induction furnace is enclosed in a gas-tight box and an inert atmosphere is supplied to this to prevent any possible oxidation or reduction of the slags under test. The slags are melted in contact with molten copper at various temperatures, and the copper and slag allowed to reach equilibrium. Samples of slag are taken from each melt and analysed [sic] to find the copper absorbed"--Abstract, leaf [i]. |
