Nov 20, 2016· Copper slag is inevitably produced by slag cleaning furnaces as a final byproduct; this type of setup is widely used in the sand-blasting industry. Although waste copper slag has several advantages as a raw material for utilization in various applications, hazardous elements (e.g., As, Pb, Bi, Sb) are dispersed physicochemically within the slag.
Control of copper in the SCF slag within the 3 to 5% range has been a challenge, due to changes in size and quality of metallurgical coke, and slag chemistry. Table II shows the average composition of SCF slag from March 2009 to December 2010. Table I: Typical analysis of Slag Cleaning Furnace (SCF) slag, mass % Cu Fe SiO2 CaO MgO Co S Al2O3 Fe3O4
Channel induction furnaces are commonly used for melting low-melting-point alloys and/or as a holding and superheating unit. Channel induction furnaces consist of a refractory-lined steel shell that contains molten metal. The two types of channel furnaces are horizontal and vertical.
Induction furnace capacities range from less than one kilogram to one hundred tonnes capacity, and are used to melt iron and steel, copper, aluminium etc. The one major drawback to induction furnace usage in a foundry is the lack of refining capacity; change material must be clean of oxidation products and of a known composition.
