1080立方的炼铁高炉,焦炭整粒到多大块度最适宜?有相关专家知道吗,需要详细的分析,及其原因!lichh2616672网友您好!,你说的单独使用,是指炼铁过程中投料的什么阶段单独使用,我一点都不懂的新手,所以问的菜了点!_百度作业帮

根据经验：你用40mm-60mm的大块焦就行了,不要太大,否则到炉内后易破碎,从而影响炉子的透气性,甚至破坏顺行.焦炭的冷态指标和热态指标很重要,1080m3的炉子最好M40要大于82%；M10要小于7%；反应性小于26%；反应后强度大于66%.满足以上条件就可以了.至于粒度15mm-25mm的焦丁可以加到矿里用,一般15kg/t铁就可以了.25mm-40mm的中块焦也可单独使用,但不如用大块焦好.以上只供朋友参考哦!

英语翻译高炉卷扬上料系统是所有中小型高炉所普遍采用的上料方式,武钢在一号高炉和二号高炉采用主卷扬上料系统.由于料批的批重不同,对速度要求也不一样,对变频器的力矩给定要求较高,给卷扬速度控制提出了很高的要求；在检修过程中,由于紧主卷扬料车钢绳需要多工种配合,经常导致高炉降压生产；在设备维护方面,由于现场环境复杂,给人工测量翻车角度带来很大困难,增加了一定的危险因素.在高炉工艺方面,每小时的料批数量也限制了高炉产量.本文主要针对主卷扬速度控制不稳定,紧主卷扬钢绳作业流程,上炉顶人工测量料车翻车角度存在安全隐患,如何保证最大的料批速度等问题,开展技术研究.本文结合一号高炉现场实际需要,开展了相应技术研究,并对研究成果进行应用,解决了主卷扬速度控制的技术难题,对紧主卷扬钢绳作业流程进行了优化,成功解决了紧钢绳作业高炉影响降压的技术难题,通过设计专用测高炉料车翻车角度仪器,并申请了国家专利,避免了人工测量料车翻车角度存在安全隐患.同时,还对高炉炉顶控制程序进行了优化,缩短了高炉装料、布料时间,在提高高炉上料速度的同时,提高了高炉产量,为高炉稳产,高产打下了良好的基础.经过我们的努力,此次研究取得了良好的效果,实现了研究目的,在实践应用中达到了预期效果,取得了圆满成功.关键词：高炉,卷扬,变频器,
Blast furnace mainly includes process automation control, feeding and ontology, and control of blast furnace control automation, main purpose is the guarantee of blast furnace operation four main problem: correct ingredients and timely loading charging, control, with certain or foundry Adjust the burden distribution and maintain the good gas flow and thermal contact, Keep the hot blast has appropriate condition. Bf automation system including instrument and control system and electric control system and the process and management with the computer.First ingredients must accurate, once appear mistake will seriously affect XiuFeng blast furnace condition, and even discontinued. Still, the equipment should be the interlocking relationship, if control disorders, waste materials, human, the person that will lead to the normal feeding, trolleys can XiuFeng blast furnace, forcing. The blast furnace has the characteristics of process industry, based on the automation function is continuous control, batch control, logistics processing as the main content, to optimize the process as the main target. Blast furnace production as the necessary supporting system for conveying equipment, the high pressure blast blast is to guarantee the stability of the necessary conditions for the blast furnace high stability. If the control disorders caused by light, wind, temperature fluctuations of blast furnace production, affect the person will blast injury and gas explosion vault. But because of blast furnace and furnace production continuity, automation control system design, equipment selection and has high reliability and emergency handling. In the production process of poisonous gas safety endangers life and explosion in automatic control system, and the equipment selection are designed to prevent danger produce measures.In traditional blast furnace process through many simulation instrument to monitor iron-making process. It includes blast furnace and furnace body temperature, pressure, and flow of numerous data monitoring, comprehensive drum wind air temperature, air pressure, wind and other parameters of the detection and control, and the cloth in furnace process simulation shows plate etc. In order to realize the blast furnace process automation control target, constantly promote computer in blast furnace production technology application. To the 1980s, realized by microcomputer as the core of PLC and DCS control system replace traditional electric furnace and instruments as basis of automation, realize the goal of blast furnace and furnace body parameters, under the roof and weighing, ingredients of coal powder injection cloth, centralized monitoring of process parameters. While many PC monitor screen on display screen, alarm screen, trend, the application of computer can make more intuitively and more accurately reflect the dynamic changes of the blast furnace process.Keywords: blast furnace, automatic control DCS高炉风口大量破损原因分析_百度文库
