Summary:This article presents the results of studies comparing the mix sintering process in a bed loosened with vertical rippers and a dense bed of a mix. In this study, for the first time, it was established that mix sintering in a loosened bed with a maximum height of 700 mm is more efficient in terms of sintering speed than that in dense beds of lower heights (up to 550 mm), without deteriorating the quality of the sinter cake. The results confirm that in a loosened bed, the vertical sintering rate of the mix increases as its height increases. This article discusses relevant problems associated with the operation of the ignition hearth, throttling of wind boxes, and energy-consuming operation of exhausters.
