Preparation of Arc Furnace for Powdered Products

Abstrak

Electric arc furnaces (EAFs) are extensively employed in steel production and nonferrous metal smelting. Typical electric arc furnaces have a power range of 10MW to 100MW. Laboratory electric arc furnace is a minimized AC electric arc furnace which consumes around 5KW of power. The aim of remodeling a minimized EAF is to refine some types of metals to have much better electrical and thermal conductivity, the way of getting these characteristics in laboratory with a cost-effective method is by melting the material using the minimized EAF, then rapidly cooling the molten metal with crushed ice put around the crucible. Using this type of EAF in combination with this cooling method will give smallest grain size possible after the material reforms in a mold (amorphous crystal shape), which is the best in terms thermal and electrical conductivity. Stainless steel is an example for the materials that could be refined in that way, which can be used in variety of applications in the biomedical field and prosthetics inside the human body.
