[交流] 摘要修改

It’s one of the key approaches for iron and steel corporations to efficiently recover the waste heat resources which are used to preheat sinter mixture in order to reduce energy consumption in the sintering process before the ignition device. Centered on the thermal performance of the sinter mixture in the drying process, mechanistic experiments such as differential thermal gravimetric analysis，forced air drying and the tunnel flashing drying, which are based on different focus, are carried out, including a series of experiments of level 10mg, level 10g, and level 100g respectively. The experimental results show that sinter mixture is a typical “three-period” drying materials, that is, the entire drying process consists of shorter rising rate period，longer constant rate period and falling rate period. At the beginning, the drying rate is faster, and then slower. Greater drying rate and the corresponding drying time is in the first 5-7 minutes when the moisture content of sinter mixture is 0.055~0.06kg (water)/kg (material) based on the experimental conditions. In the experiment of tunnel flashing drying, critical moisture content of sinter mixture is about 2.3~3.0%. The temperature and flow rate of hot air are the main factors affect the drying rate, within a certain range, the higher the air temperature the greater the flow as well as the drying rate, the effect of strengthening drying is more obvious. Both hot air temperature and flow should have an appropriate scope dues to the discrepancies exist in the effect of strengthening drying by improving the temperature and flow in different interval. Therefore, sinter mixture is easy to dry, and the existing low temperature waste heat is able to achieve sinter mixture’ drying.

求助 摘要修改~！！谢谢

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

大概改了一下，摘要中要用过去式，还有，楼主用的长句子太多，最好长短穿插。In order to reduce energy consumption in the sintering process before the ignition device， one of the key approaches for iron and steel corporations to efficiently recover the waste heat resources used to preheat sinter mixture. Centered on the thermal performance of the sinter mixture in the drying process, mechanistic experiments such as differential thermal gravimetric analysis，forced air drying and the tunnel flashing drying based on different focus, are carried out, including a series of experiments of level 10mg, level 10g, and level 100g(,) respectively. The experimental results show(ed) that sinter mixture is（was） a typical “three-period” drying materials, that is, the entire drying process consists（ed） of shorter rising rate period，longer constant rate period and falling rate period. At the beginning, the drying rate is faster(fast), and then slower(slow down). Greater drying rate and the corresponding drying time is in the first 5-7 minutes when the moisture content of sinter mixture is 0.055~0.06kg (water)/kg (material) based on the experimental conditions. In the experiment of tunnel flashing drying, critical moisture content of sinter mixture is about 2.3~3.0%. The temperature and flow rate of hot air are the main factors affect the drying rate, within a certain range, the higher the air temperature (is,) the greater the flow as well as the drying rate, the effect of strengthening drying is more obvious. Both hot air temperature and flow should have an appropriate scope dues to the discrepancies exist in the effect of strengthening drying by improving the temperature and flow in different interval(s). Therefore, sinter mixture is easy to dry, and the existing low temperature waste heat is able to achieve sinter mixture’ drying.
