弱氧化性气氛 meaning in English

weakly oxidizing atmosphere

Abstract : during the reduction of iron ore - coal pellet in air , the combustible gas generated from the reduction in pellet is burnt onto the firing surface around the pellet . between the pellet surface and the firing surface , ther e is such mixing gas containing the combudstible gas and burnt gas . it m ay b e sure that the iron ore - coal pellet is no oxidized in the week oxidizing atmos phere . the heat released by combusition on the firing surface is fast tranfered i nto the pellet , and the self - heating reduction of iron ore - coal pellet may occu r
文摘:铁矿-煤球团在空气中能够还原的原因是：从球团排出的可燃性气体在球面附近的火焰面上燃烧，在火焰面内侧是氧化性较弱的可燃性气体和燃烧产物的混合物，铁矿-煤球团在弱氧化性气氛中具有抗氧化性；在火焰面燃烧放出的热量向球团传递，进行自热还原
