| 4 | 煤的粒度对Corex生产指标的影响显示文摘Corex工艺用煤的粒度分布是最重要的,它决定了半焦床的透气性和稳定性,因而影响气化炉的生产指标。煤的粒度可以用平均粒度(MPS)和小于6.3mm入炉煤粉比例来监测。降低煤中小于6.3mm煤粉比例和提高煤的平均粒度,都有利于改善气化炉的状况和性能。MPS和小于6.3mm入炉粉率的波动会影响燃料比,并使气化炉炉况不稳定,减少产量。采用工厂数据进行了理论计算,可知煤的粒度对熔融气化炉(MG)料床透气性的影响。采用统计分析方法研究了煤的粒度对Corex生产指标的影响,并尝试建立了入炉煤的粒度与Corex生产指标间的关系。研究结果表明:要使炉况稳定,并改善Corex的性能,要求煤的平均粒度控制在19~22mm范围内,小于6.3mm的粉末比例<15%。得出了燃料比与煤的粒度等因素关系的回归方程式。讨论了煤的粉率和平均粒度对Corex生产指标的影响。 | P Prachethan Kumar Y S Rao K Chidambaran M Ranjan 徐万仁(译) 王臣(校) | 2010 | 世界钢铁2010，，4： | 1 |

| 20 | COREX—learnings and innovations at JSW Steel Limited显示文摘Ultra pure ferritic stainless steel is a kind of new stainless steel grade with high quality developed in the mid-twentieth century,it is characterized by ultra low Carbon and Nitrogen content and micro-alloying with Ti, Nb,V,Cu etc.,so it overcomes a lot of use shortcomings of the ordinary ferritic stainless steel,such as intergranular corrosion sensitivity,low ductility and toughness under atmosphere temperature,crack inclining at the weld zone etc.,namely,it has better performance than the ordinary ferritic stainless steel in the aspect of corrosion resistance,toughness and weldability etc.Furthermore,a series of secondary refining equipments and technologies have been invented from the 1960s,low or ultra low Carbon and Nitrogen content in the molten stainless steel can be obtained during manufacturing production.Therefore,such steel has been applied in many fields,leading to the very rapid development over the past half century. This paper focuses on the secondary refining process which is the most important step of the whole steel-making process for the ultra pure ferritic stainless.Firstly,some difficulties of the secondary refining process are described,including the high purification in terms of both Carbon and Nitrogen contents,high efficient and stable control.Secondly,the development and progress of the secondary refining technology for ultra pure ferritic stainless is introduced in terms of the refining equipments,metallurgical process and assistant technologies.Some most famous secondary refining equipments and metallurgical technologies for ultra pure ferritic stainless steel had been invented mainly by Japan and European companies from 1960s to 1990s,such as VOD,SS-VOD,AOD-VCR, VOD-PB etc..During the same time of wide application of these secondary refining equipments and technologies,in order to strengthen the function and capacity of these refining equipments,some advanced assistant technologies were also introduced and applied,which consists of top lance,special raw materials,ladle refractory,process monitoring and mathematic model and so on.Finally,the prospect in the future was made for the development of secondary refining process for ultra pure ferritic stainless in terms of high efficiency,ultra purification,stable control with process model etc. | P Prachethan KUMAR | 2010 | Baosteel Technical Research2010，4，S1： | 0 |
