Efficient recovery and utilization of waste heat during sintering is crucial for iron and steel industry (or plants, not enterprises) in China. The thermal performance of the prepared granulated sinter mixes in the dry zone, in the weight range of 10mg, 10g, and 100g, respectively, was investigated using the techniques like thermogravimetric and differential thermal analysis. The results indicated that the drying of a sinter mix consisted of three stages, including a short rising-rate period, a long constant-rate period, and a certain falling-rate period, ascribed to the drying behavior. Depending on the sintering conditions, the moisture contents of samples were 5.5-6.0% by weight of solid in the first 5-7 minutes, and the critical moisture contents were approximately 2.3-3.0% after the flash drying through a tunnel dryer. It was found that the drying efficiency could be improved within a certain range by increasing the temperature, which played a greater impact, and the flow rate of the hot air. Overall, the result was suggestive of rational capabilities of the low-temperature waste heat for drying the sinter mixes in the iron and steel industry.
大概给你改了改,希望对你有所帮助吧~括号内的是注释,你看完可以删掉。
你原文主要的问题出了语法,貌似还有专业词汇的使用~我去google你用的那些词组,都不太能找到,我帮你重新改过了,但是因为不是你们专业,所以不确定是不是你想要的意思。建议你以后翻译专业词汇时直接去找英文文献,不要单纯依赖辞典,呵呵 |
