Description
Изобретение относитс к области черной металлургии, конкретнее к управлению процессом в двухьанных сталеплавильных печах.The invention relates to the field of ferrous metallurgy, and more specifically to the process control in double-steel steel-smelting furnaces.
Известны способы управлени сталеплавильным процессом в двухванных печах, включающие контроль основных технологических параметров; в частности содержани углерода в продувочной ванне и теплосодержани скрапа в холодной ванне .Known methods for controlling the steelmaking process in double-barred furnaces include monitoring the main process parameters; in particular, the carbon content in the purge bath and the heat content of the scrap in the cold bath.
Известные способы управлени процессом в двухванных печах предусматривают поддержание максимального теплопоглощени скрапа.The known process control methods in two-bath furnaces provide for maintaining the maximum heat absorption of scrap.
Однако при таких способах в случа х замедлени процесса обезуглероживани происход т перегрев и перекисление скрапа.However, with such methods, in cases of slowing down the decarburization process, overheating and perekislenie scrap will occur.
цель изобретени состоит в синх ронизации работы ванн.The purpose of the invention is to synchronize bath operation.
досгигаетс это тем, что поддерживают текущее значение теплосодержани скрапа в холодной ванне в зависимости от содержани .углерода в продувочной ванне изменени расхода топлива в холодную ванну.This is achieved by maintaining the current value of the heat content of the scrap in the cold bath, depending on the content of carbon in the purge bath, the change in fuel consumption in the cold bath.
Теплосодержание скрапа определ ют путем интегр1фовани мгновенных значений теплопоглощени , которые, в свою очередь, определ ют балансовым методом. Завионмость мевду текущими значени ми содержани углерода и теплосодерхани скрапа определ ют эвширически на серии опытных плавок з услови оптимальною нагрева скрапа к моменту достижени заданного содержани углерода в по продувочной ванне.The heat content of the scrap is determined by integrating the instantaneous values of heat absorption, which, in turn, are determined by the balance method. The availability of the current carbon content and scrap thermal heat content is determined euchirically on a series of experimental heats under the condition of optimal heating of the scrap by the time it reaches the specified carbon content in the scrubber bath.
ПРЩЩЁТ ИЗОБРЕТЕНИЯPREFERRED INVENTIONS
Способ управлени плавкой з двухванной сталеплавильной печи, включаю(ций измерение теплосодержани скрапа в холодной ванне и содержани углерода в продувочной ванне,0 тличающиис тем, что, с целью синхронизации работы ванн, поддерживают текущее значение теплосодержани скрапа в зависимости от содержани углеIрода путем изменени расхода топлива в холодную ванну.The method of controlling fusible from a two-bath steel-smelting furnace, includes (measuring the heat content of scrap in a cold bath and carbon content in the blow-down bath, 0 by the fact that, in order to synchronize the operation of the baths, the current value of the heat content of scrap depends on the carbon content by changing the fuel consumption in a cold bath.
