自从1829年开始使用热风以来,高炉工作者就深知热风对于降低焦比有着特别重要的作用。就现代高炉而论,可以毫不夸张地说,热风对于焦比的影响,仅次于熔剂性烧结矿的应用。虽然如此,到目前为止高炉工作者对于有无极限风温的问题,以及进一步提高风温还能节省多少焦比的问题,都不是没有争论的。从理论上回答这些问题,就是本文的目的。提高风温引起焦比降低的原因在使用热风的初期就已经发现:提高风温节省的燃料量远远地超过了热风带入的热量,为了正确地解释这种现象,??贝尔P.阿克尔曼以及M.A.巴甫洛夫做了许多工作,根据这些研究结果,可以看出节省
Since the beginning of the use of hot air in 1829, blast furnace workers have come to know that hot air has a particularly important role in reducing coke. In the case of modern blast furnaces, it is no exaggeration to say that the influence of hot blast on the coke ratio is second only to that of flux sinter. Nevertheless, it is not without debate that blast furnace workers have so far been able to solve the problem of whether there is ultimate air temperature and how much further coke air temperature can be saved. To answer these questions theoretically is the purpose of this article. The reason for the increase in the air temperature causing a reduction in the coke ratio has been found in the early stages of the use of hot air: the amount of fuel required to raise the air temperature is far more than the heat brought in by the hot air. In order to correctly explain this phenomenon, Kerman and MA Pavlov did a lot of work, based on these findings, we can see savings
