本文系沈阳农业机械厂在1957年所作的冲天炉工作总结,文中介绍了该厂的冲天炉改装工作及改装后的实际效果。其中,废气的回用装置是值得注意的。如何使这一装置更趋合理,使废气的热能得到更充分的利用,还需要作进一步的研究。至于把焦铁比提高到1∶22-23左右(层焦层铁比,包括接力焦,不包括底焦)却与一般公认的不能高于1∶15的原则相违背,希望大家慎重考虑并展开讨论。目前,对三排小风口冲天炉的认识还不统一,在结构方面还没有完善的典型设计,在实践上也没有一套正规的操作方法,为了改进冲天炉熔化工作,合理地提高冲天炉热效率,特刊出本文供大家广泛讨论。—编者
In this paper, Shenyang Agricultural Machinery Factory in 1957 made a summary of the cupola, the paper describes the factory modified cupola and the actual effect after modification. Among them, the exhaust gas recycling device is noteworthy. How to make this device more reasonable and make the heat energy of exhaust gas get more fully use, need further research. However, it is contrary to the generally accepted principle of not being higher than 1:15 to raise the ratio of coke to iron around 1:22-23 (layer coke ratio, including relay coke, excluding bottom coke), and we hope everyone will consider it carefully open discussion. At present, the understanding of the three rows of small-outlet cupola is not uniform, the structure is not perfect typical design, in practice there is no set of formal methods of operation, in order to improve the cupola melting work, to improve the thermal efficiency of the cupola reasonably , Special issue of this article for your extensive discussion. -editor
