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~��！謝謝 |

| 大概改了一下，摘要中要用過去式，還有，樓主用的長句子太多，最好長短穿插。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. |

Efficient recovery and utilization of waste heat in sintering process is a great challenge for iron and steel enterprises in China. In this paper a series of experiments of sinter mixture in drying process were developed, and the sinter mixture was divided into three orders of magnitude in weight, 10mg, 10g, and 100g, respectively. The experimental results showed that sinter mixture’s drying process can be divided into three stages according to the drying rate, i.e., the short rising rate drying, the long constant rate drying and certain falling rate drying. Based on the experimental conditions, the moisture content of sinter mixture is 0.055~0.06kg (water)/kg (material) in the first 5-7 minutes, the critical moisture content of sinter mixture is about 2.3~3.0%, the hot air temperature and flow rate are the main factors affect the drying process, within a certain range, the influence must be bigger than drying process obviously to hot air temperature to flow rate the influence, the hot air temperature is higher, the flow rate is greater, so lead to the drying rate bigger, drying time shorter. The encouraging results can provide fundamental data for rational utilization of waste heat in sintering process. 請高人，從句子結(jié)構(gòu)，語法，及整個摘要的 宏觀層次上，提出意見~！ 謝謝 |

Efficient recovery and utilization of waste heat in sintering process is very crucial to iron and steel industry (enterprises) in China. In this paper a series of experiments on sinter mixture during a drying process were carried out , and the sinter mixtures were categoried into three weightlevels , 10mg, 10g, and 100g, respectively. The sinter mixture’s drying process can be divided into three stages according to the drying rate, i.e., the low rising rate of drying, the high rising rate of drying and a fixed falling rate of drying. The experimental results showed that Based on the experimental conditions, the moisture content of sinter mixture is 0.055~0.06kg (water)/kg (material) in the first 5-7 minutes, the critical moisture content of sinter mixture is about 2.3~3.0%. The temperature of hot air and the flow rate are the main factors affecting the drying process. within a certain range, the influence of hot air temperature is bigger than the flow rate in the drying process obviously .the higher the hot air temperature is , the larger (greater) the flow rate, which leads to a bigger drying rate and shorten the drying time .The study's results can provide fundamental data for a promising reasonable utilization of waste heat in sintering process. |

| 感覺樓主的二稿過于直白了，不夠?qū)W術(shù)呀~今天有點忙~沒辦法幫樓主仔細(xì)改了，抱歉！在這里先提點建議：建議樓主先看看相關(guān)文獻的摘要的用語再大修一下！還有貌似基本沒有在摘要里看到過"in this paper“的用法，直接描述實驗內(nèi)容即可。下面那句話請務(wù)必修改，一來太長，二來太碎！句子與句子之間甚至沒有必要的連接詞，只是用逗號隔開，語法上也說不通呀，對不？實在想不出辦法可以加一些"in addition"之類的廢話嘛！"Based on the experimental conditions, the moisture content of sinter mixture is 0.055~0.06kg (water)/kg (material) in the first 5-7 minutes, the critical moisture content of sinter mixture is about 2.3~3.0%, the hot air temperature and flow rate are the main factors affect the drying process, within a certain range, the influence must be bigger than drying process obviously to hot air temperature to flow rate the influence, the hot air temperature is higher, the flow rate is greater, so lead to the drying rate bigger, drying time shorter.
