WebLead Refining /alloying system is a pyro-metallurgical process. In the processing of pure Lead, smelted Lead bullion (output of Rotary Furnace) are being collected in a refining pot/kettle for further treatment of impurities/dross. There are certain dross removal procedures and time involving in this process depending on the composition ... WebS3: Carry out secondary refining on the molten aluminum after alloying in the holding furnace, add granular refining agent at 2.8kg/t, and use high-purity nitrogen with a purity ≥ 99.999% for refining. After that, slag removal is carried out, the refining temperature is set at 790°C, and the refining is allowed to stand for 45 minutes. maria mitchell significance https://ninjabeagle.com
