摘要

In the present research, means of reducing the content of the >80 mm class in metallurgical coke at coke batteries 1, 3, and 4 of Ural Steel are considered, in the light of the need to minimize batch cost and maximize coke quality (specifically, the strength indices M10 and M25). This problem was suggested by students in production education groups at the Novotroitsk branch of Moscow Institute of Steel and Alloys (MISIS). This first article in the series is a literature review, beginning in the 1960s. The influence of the following factors on the content of the >80 mm class is discussed: the rank composition of the batch; its moisture content; and coking parameters such as the coking time, the temperature in the controlled heating channels, and the coking rate. The second article will be devoted to mathematical analysis of a passive experiment based on Ural Steel data, with the goal of identifying the factors affecting the content of the >80 mm class in the coke produced at Ural Steel; the results of this analysis will be compared with literature data. The third article will present models of the content of the >80 mm class in the coke produced, with subsequent optimization and testing by laboratory coking.
