Smelting furnace is for light metals. There is an inductive stirrer under its bottom which induces a horizontal linear flow of molten metal towards part of the surface of the furnace. An inert gas is blown into the melt under this area of the surface. This forms a curtain of gas bubbles which prevents the deposition of oxides on the surface. - Provides smelting furnace for aluminium, magnesium etc. (Provisional Basic previously advised in Week 83/33)(0/1) |
