【正文】 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. 、論文背景 . The background of the paper 一、論文由來(lái) 1. Origin of the Paper 為了降本增效和節(jié)約優(yōu)質(zhì)煉焦煤，邯鋼焦化廠從煤資源合理配煤煉焦入手，一直致力于開(kāi)展一系列的新型配煤煉焦方法的研究，達(dá)到降低焦炭成本。 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 cokeoven, and obtained the aim to reduce high quality coking coal. 、實(shí)驗(yàn)?zāi)康? . The aim of this experiment 煤粉改性劑是一種新型煉焦催化產(chǎn)品，為白色乳液狀液體，主要由釩、鑭、鐵等催化元素制成的絡(luò)合物。 Powder coal’s modified agent is one kind of new coking catalyzer, which is milkiness liquid and a floccule which contains coking catalyzer elementary of vanadium, lanthanum and iron. 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. 、煤粉改性劑簡(jiǎn)介 . Introduction of powder coal’s modified agent 在焦?fàn)t中，煤粉改性劑可以催化煤粉裂解，使煤的熱分解特征發(fā)生變化，熱解產(chǎn)物增加，熱解溫度區(qū)間增寬，膠質(zhì)體生長(zhǎng)時(shí)間延長(zhǎng)，從而有利于改善配合煤的結(jié)焦性能，使焦炭的冷、熱強(qiáng)度提高。 In the cokeoven, 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. 、論文意義 .
