Description

эа счет увеличени  объема подачи (расширени  диапазона варьировани  объемом подачи), увеличить производительность системы загрузки за счет .совмещени  операций осыпани  шихты со шлюзовой камеры и засыпного аппарата, уменьшить капитальные затраты на строительство и уменьшить дробление шихты за счет снижени  высоты загрузочного устройства (при заданном объеме подачи). Увеличение производительности системы загрузки может быть достигнуто также в тех устройствах, где врем  загрузки шлюзовой камеры меньше времени ее опо рожнени  (например, трехконусные загрузочные устройства при скиповой заггрузке ),, Технико-экономическа  эффективност способа загрузки по изобретению складываетс  из уменьшени  расхода кокса и увеличени  производительности доменноЯ печи за счет лучшего использовани  газового потока и большей подачи шихты. Формула: изобретени  Способ загрузки доменной печи засыпным аппаратом, включающий набор шихтовых материалов в герметичную камеру и через шлюзовую камеру периодическую выгрузку их в печь, отличающийс  тем, что, с целью увеличени  единичного объема загружаемого материала, загрузку печи осуществл ют при одновременном открывании затворов герметичной камеры и нижнего затвора шлюзовой камеры. Источники информации, прин тые во внимание при экспертизе: 1. Авторское свидетельство СССР 447432, кл. С 21 В 7/20, 1970.at the expense of increasing the supply volume (expanding the range of variation in the supply volume), increase the capacity of the loading system by combining the charge shedding from the sluice chamber and charging unit, reduce capital construction costs and reduce the crushing of the charge by reducing the height of the loading device (for a given volume filing). Increased loading system performance can also be achieved in those devices where the loading time of the sluice chamber is shorter than its emptying time (for example, three-cone loading devices with skip loading), the technical and economic efficiency of the loading method according to the invention consists of reducing coke consumption and increasing productivity blast furnace due to better use of the gas stream and greater supply of the charge. Formula: Invention A method of loading a blast furnace with a charging apparatus, including a set of charge materials into a sealed chamber and through a lock chamber, periodically unloading them into a furnace, characterized in that, in order to increase the unit volume of feed material, the furnace is loaded while simultaneously opening the valves of a sealed chamber and lower lock airlock.
