摘 要: 以氧化鋁生產(chǎn)流程的基準物流圖概念為基礎(chǔ)， 構(gòu)筑了拜耳法生產(chǎn)氧化鋁流程的基準物流圖， 為定量分析拜耳法流程中物流對能耗的影響提供了一個比較的基準，并以某拜耳法氧化鋁廠生產(chǎn)數(shù)據(jù)為依據(jù)， 繪制了該廠的實際物流圖， 構(gòu)筑了與其相對應的基準物流圖。 用基準物流圖法定量地分析了各個工序的工序能耗變化和折合比變化對氧化鋁綜合能耗的影響，以及生產(chǎn)流程中物流對能耗的影響， 為指導該廠今后的節(jié)能降耗工作提供了定量的依據(jù)。

Abstract:Based on the concept of standard materials flow diagram (SMFD) of alumina manufacturing process, the SMFD of alumina manufacturing process by Bayer method was constructed. A comparative benchmark for analyzing the influence of material flow on energy intensity was provided. On the basis of the data of an alumina manufacturing plant by Bayer method, the real material flow diagram of this plant was drawn and the SMFD was constructed accordingly. The influence of the change of the unit process energy intensity and the alumina-process product-ratios on the overall energy intensity and the influences of material flow in a manufacturing process on its energy intensity were analyzed quantitatively as an example.
Key words: alumina； Bayer method； standard materials flow diagram； real materials flow diagram； overall energy intensity； unit process energy intensity
