In the vertical furnace charging manner and the charging apparatus

摘要

PURPOSE: To solve the problem of the restriction in the selection width for control of the conventional bell-less charging method in the charging method for a vertical furnace, such as blast furnace or the grain size segregation in the bell-less charging method. ;CONSTITUTION: The falling loci 3 of the charge in the vertical furnace, such as blast furnace, are controlled by blowing air or inert gas to the falling charge and regulating the position where the gas is blown at this time and the amt. and flow velocity of the gas at the time of charging the charge into the vertical furnace.;COPYRIGHT: (C)1993,JPO&Japio
