降本增效是企业生存和发展的最为重要的长期奋斗目标2009年我国焦炭产量已经超过年我国焦炭产量已经超过3亿吨，年消耗各种炼焦煤量亿吨，年消耗各种炼焦煤量约约4亿吨炼焦所用煤种主要是强粘结性的烟煤，目前强粘结亿吨炼焦所用煤种主要是强粘结性的烟煤，目前强粘结性煤炭资源的需求日益紧张，炼焦用煤的价格也在年年攀升，性煤炭资源的需求日益紧张，炼焦用煤的价格也在年年攀升，焦化企业已经陷入了不断增加的成本困境和采购难的困境，焦化企业已经陷入了不断增加的成本困境和采购难的困境，降低炼焦成本、缓解煤炭资源紧张的矛盾已经成为焦化企业降低炼焦成本、缓解煤炭资源紧张的矛盾已经成为焦化企业迫切需要解决的问题迫切需要解决的问题 Energy⁃ ⁃saving and cost⁃ ⁃reducing is the most important aim of survival and development for corporations. In the year of 1999, the output of coke in China was more than 300 million ton, and 400 million ton of coking coals was consumed. We all know that coking coals are most of soft coals which have strong caking property. The requirement of strong caking property coals is more and more intensity and its price is higher and higher. Coking plants is already more and more difficult to stock coking coals and to decrease cost. We should try hard to settle these problems.1.1、论文背景1.1. The background of the paper一、论文由来一、论文由来1. Origin of the Paper 为了降本增效和节约优质炼焦煤，邯钢焦化厂从煤资源合理配煤炼焦入手，一直致力于开展一系列的新型配煤炼焦方法的研究，达到降低焦炭成本。

在这期间，进行了煤粉改性剂配煤炼焦的小焦炉试验研究，达到了减少优质炼焦煤配入量的目标 For energy⁃ ⁃saving and cost⁃ ⁃reducing and saving high quality coking coal, Han steel coking plant begin with rational coking and blending coal, and take up with researching a series of new coking coal blending methods, to achieve reducing coking cost. In this period, Han steel coking plant put up with the experimental research about using powder coal’s modified agent to blend coking coals in the small coke-oven, and obtained the aim to reduce high quality coking coal. 1.2、实验目的1.2. The aim of this experiment 煤粉改性剂是一种新型炼焦催化产品，为白色乳煤粉改性剂是一种新型炼焦催化产品，为白色乳液状液体，主要由钒、镧、铁等催化元素制成的络合液状液体，主要由钒、镧、铁等催化元素制成的络合物。

Its quality is steady and it will not be degenerative for a long time in normal environment. We just do one thing to swag powder coal’s modified agent for a short time when we use it blending with coking coals. Coal preparation workshop in a coking plant need to be equipped simple apparatus to use powder coal’s modified agent to be blended with coking coals.1.3、煤粉改性剂简介1.3. Introduction of powder coal’s modified agent  在焦炉中，煤粉改性剂可以催化煤粉裂解，使煤的热在焦炉中，煤粉改性剂可以催化煤粉裂解，使煤的热分解特征发生变化，热解产物增加，热解温度区间增宽，分解特征发生变化，热解产物增加，热解温度区间增宽，胶质体生长时间延长，从而有利于改善配合煤的结焦性能，胶质体生长时间延长，从而有利于改善配合煤的结焦性能，使焦炭的冷、热强度提高。

在保证焦炭质量的前提下，添使焦炭的冷、热强度提高在保证焦炭质量的前提下，添加极少量的煤粉改性剂，不但能达到降低优质炼焦煤，增加极少量的煤粉改性剂，不但能达到降低优质炼焦煤，增加弱粘结性煤的配入量的目的，降低配煤炼焦成本的目标，加弱粘结性煤的配入量的目的，降低配煤炼焦成本的目标，而且将缓解河北钢铁集团甚至河北省优质炼焦煤使用危机，而且将缓解河北钢铁集团甚至河北省优质炼焦煤使用危机，适应国家能源利用可持续发展的要求适应国家能源利用可持续发展的要求 In the coke-oven, powder coal’s modified agent can catalyze coking coal pyrolysis, and change the character of coking coal pyrolysis, and increase pyrolysis productions, and broaden pyrolysis temperature section, and extend plastic developing time. It is also good for improving coking properties of coordinate coal and makes cold and hot intensity increased. At the effect of little quantity of powder coal’s modified agent, it can not only decrease the quantity of good coking coals and reduce the cost of coking coal blending, but also relax the pressure of stock good coking coals for Hebei steel Co., LTD and Hebei Province. It is fit for the sustainable development of energy sources using require in China.1.4、论文意义1.4.

从表列出了各组配合煤的化验结果从表3可以看出：可以看出： （（1）各组小焦炉试验的煤种是通过不同比例的各种煤样）各组小焦炉试验的煤种是通过不同比例的各种煤样配合得到的，在配煤过程中，需要把所有的配合煤的水分配合得到的，在配煤过程中，需要把所有的配合煤的水分都调到都调到10.00% （（2）所有配合煤的灰分都在）所有配合煤的灰分都在9.00%-10.00%之间，配之间，配合煤灰分的差异主要是因为不同种类的煤样的配比不同，合煤灰分的差异主要是因为不同种类的煤样的配比不同，而煤粉改性剂配入量不足而煤粉改性剂配入量不足0.1%，它基本上不影响到配合，它基本上不影响到配合煤的灰分煤的灰分 （（3）各组试验配合煤的全硫含量在）各组试验配合煤的全硫含量在0.8%-0.9%之间 Tab. 3 lists the assay results of all experimental coordinate coals. We know from Tab. 3 that, (1) In the course of coking coals blending, we should make all experimental coordinate coals’ moisture 10.00 percent. (2) Ash contents of all experimental coordinate coals were between 9.00% to 10.00%. The differences of coordinate coals’ ash contents was mainly because of different kind and proportion of coals. (3) Sulfur contents of all experimental coordinate coals were between 0.8% to 0.9%. （（4）所有配合煤的粘结指数都在）所有配合煤的粘结指数都在80左右，胶质层最左右，胶质层最大厚度都在大厚度都在13.5mm-18mm之间，胶质体随温度之间，胶质体随温度变化的图形大多都是变化的图形大多都是“之字之字”或或“波形波形”，说明所有，说明所有的配合煤都有焦煤的性质，适合配煤炼焦的使用，试的配合煤都有焦煤的性质，适合配煤炼焦的使用，试验的选煤和混合是比较合理。

验的选煤和混合是比较合理 （（5）各组试验的配合煤的挥发分含量都在）各组试验的配合煤的挥发分含量都在25%-27%之间表3表明，在所有试验配比中，由于表明，在所有试验配比中，由于KZ煤为煤为1/3焦煤，挥发分含量在焦煤，挥发分含量在36 %daf.以上，所以以上，所以增加增加5%的的KZ煤的试验配合煤的挥发分都比其他配煤的试验配合煤的挥发分都比其他配合煤的挥发分含量要高合煤的挥发分含量要高 (4) Bond index of all experimental coordinate coals were around 80, and maximum thickness of plastic layers were between 13.5mm to 18mm, and the figures of plastic with the change of temperature were most of Z form or waveform. So we knew that all experimental coordinate coals with the character of coking coal were fit for blending and coking. In other words, it was relative scientific that we chose and blend coking coals. (5) Volatile contents of all experimental coordinate coals were between 25% to 27%. Tab. 3 was shown that KZ coal was 1/3 coking coal with more than 36%daf. Volatile contents, so the volatile contents of experimental coordinate coals were higher because we increased the mixing proportion of KZ coal  （（6）所有配合煤的塑性温度区间都在）所有配合煤的塑性温度区间都在100oC以上，以上，且所有配合煤的最大流动度都在且所有配合煤的最大流动度都在1000dd/min-6000dd/min之间，都具有焦煤的热性质。

从表之间，都具有焦煤的热性质从表3还还可以看出，配入煤粉改性剂的配合煤塑性温度区间比空可以看出，配入煤粉改性剂的配合煤塑性温度区间比空白试验的配合煤的塑性温度区间平均要宽一些，最大流白试验的配合煤的塑性温度区间平均要宽一些，最大流动度也要大一些，说明煤粉改性剂在煤炼焦过程中对胶动度也要大一些，说明煤粉改性剂在煤炼焦过程中对胶质体的性能是有所改善，更适合配煤炼焦质体的性能是有所改善，更适合配煤炼焦 (6) Plastic temperature interval of all experimental coordinate coals were more than 100 oC, and maximum fluidity were between 1000 dd/min to 6000 dd/min which were thermal properties of coking coal. It was shown on Tab.3 that plastic temperature interval and maximum fluidity of experimental coordinate coals increasing powder coal’s modified agent were more than blank test of coordinate coals. So powder coal’s modified agent can improve the capability of plastic and make coordinate coals more suitable for coking.实验方案确定实验方案确定 Experimental project confirmed论文由来论文由来 Origin of the Paper一实验装置介绍实验装置介绍 Introduction of experimental equipment二实验煤种分析实验煤种分析 Experimental coal kinds analysis3四配合煤化验结果与分析配合煤化验结果与分析 Coordinate coals assay results and analysis三3五实验焦炭结果分析实验焦炭结果分析 The assay results of experimental coke3六经济效益概算经济效益概算3七论文总结论文总结3八主要汇报内容主要汇报内容General Condensed Summary六、实验焦炭结果分析六、实验焦炭结果分析6.

相比空白试验来说，第三组炭的质量也随之呈线性增加的趋势相比空白试验来说，第三组和第四组试验焦炭的冷强度变差一些，虽然第三组试验焦炭的反和第四组试验焦炭的冷强度变差一些，虽然第三组试验焦炭的反应后强度应后强度CSR降低，但其反应性降低，但其反应性CRI都有所改善，且第四组实验都有所改善，且第四组实验焦炭的反应后强度和反应性都比空白试验的要高目前肥煤和焦焦炭的反应后强度和反应性都比空白试验的要高目前肥煤和焦煤的价格一直居高不下，在保证焦炭质量不降低的情况下，用煤的价格一直居高不下，在保证焦炭质量不降低的情况下，用1/3焦煤代替肥煤或焦煤炼焦，焦炭成本将降低很多焦煤代替肥煤或焦煤炼焦，焦炭成本将降低很多 In Map 1 and Map 2, we knew that cold and hot intensities for the experiments adding powder coal’s modified agent were more than those of blank tests. As the increase of the coal’s modified agent amount, the coke quality also showed a linear-increase trend. Compared with the blank test, the third group and the fourth group test coke cold intensity variation, although the third groups test coke strength after reaction in CSR decreased, but the reaction of CRI are improved, and the fourth groups of experimental coke strength after reaction and reaction of blank test is higher than. The fat coal and coking coal prices have been high, in ensuring the coke quality is lower, with 1 / 3 coke instead of coal or coke coke, coke cost will be reduced a lot. 实 验 结 果实验方案确定实验方案确定 Experimental project confirmed论文由来论文由来 Origin of the Paper一实验装置介绍实验装置介绍 Introduction of experimental equipment二实验煤种分析实验煤种分析 Experimental coal kinds analysis3四配合煤化验结果与分析配合煤化验结果与分析 Coordinate coals assay results and analysis三3五实验焦炭结果分析实验焦炭结果分析 The assay results of experimental coke3六经济效益概算经济效益概算3七论文总结论文总结3八主要汇报内容主要汇报内容General Condensed Summary 综合考虑焦炭的热强度、冷强度、煤炭价格和试验结果等因综合考虑焦炭的热强度、冷强度、煤炭价格和试验结果等因素，邯钢焦化厂用素，邯钢焦化厂用5%的的1/3焦煤代替焦煤代替5%的焦煤的焦煤1号，再添加号，再添加0.05%的煤粉改性剂来进行大焦炉生产，吨煤将降低成本达到的煤粉改性剂来进行大焦炉生产，吨煤将降低成本达到15元，除去煤粉改性剂成本和工艺改进的费用，煤粉改性剂配元，除去煤粉改性剂成本和工艺改进的费用，煤粉改性剂配煤炼焦的吨焦成本降低将达到煤炼焦的吨焦成本降低将达到10元以上，邯钢每年的配合煤用元以上，邯钢每年的配合煤用量达到量达到560万吨，每年为邯钢创效达到万吨，每年为邯钢创效达到5600万元。
