Flexible Furnace Concepts for Vacuum Heat Treatment Combined with High-pressure Gas Quenching Karl Ritter1,Stefan Wiebach1 (1.ALD Vacuum Technologies AG, Hanau - Germany) 摘要:IN the past five years.... In the meantime furnace concepts for various applications are available to the industry. In the following report three plant varieties are introduced, which differ in process flexibility and throughput......
Thermodynamic modeling of lead blast furnace TAN Peng-fu(谭鹏夫) (Mount Isa Mines Limited, Queesland 4825, Australia) Abstract: A thermodynamic model was developed to predict the distribution behavior of Cu, Fe, S, O, Pb, Zn, As, and the heat balance in a lead blast furnace. The modeling results are validated by the plant data of a lead smelter in Kazakhstan. The model can be used to predict......
