Aug 22, 2020 · Refining is a very important process in aluminum smelting process. The refining flux should be selected correctly and its dosage should be controlled to increase the alloy quality by 0.5% – 0.7%. Master the refining temperature, usually control the refining temperature at 700-720 ℃. During the aluminum melt refining process, approximately 2 / 3 of the refining flux is pressed into the molten surface in batches with a bell shaped cover, and then it is rotated slowly and evenly clockwise.

Gold Smelting & Metal Melting Equipment - 911Metallurgist

Electric-Furnace Refining of Pig Iron. High-silicon pig irons smelted from Rogers and Black Mountain ores were refined in indirect-arc and induction furnaces. The objectives were to remove major portions of the silicon, carbon, and phosphorus through oxidation and slagging or, in the case of carbon, oxidation and volatilization. Refining involved maintaining oxidizing conditions over the molten iron by using oxidizing slags or lancing directly with air, oxygen, or air-oxygen mixtures.
