Description

(54) СИСТЕМА РЕГУЛИРОВАНИЯ ДАВЛЕНИЯ В МЕТОДИЧЕСКОЙ(54) PRESSURE REGULATION SYSTEM IN THE METHODOLOGICAL

II

Изобретение относитс  к черной металлургии , конкретнее к автоматизации процесса нагрева металла в методических печах.The invention relates to ferrous metallurgy, and more specifically to the automation of the process of heating a metal in process furnaces.

Известна система регулировани  давлени  в рабочем пространстве методической печи, содержаща  контур, регулирующий давление взаимодействием на дымовой шибер 1.A known system for regulating pressure in the working space of the furnace furnace, comprising a circuit regulating the pressure by the interaction on the smoke gate 1.

Недостатком известной системы в услови х переменкой производительности агрегата, определ емой работой стана и другими возмущени ми,  вл ютс  значительные колебани  давлени  в сварочных (особенно нижних) зонах, что приводит к увеличению подсосоввоздуха в печь, повышенному угару металла и, в конечном счете, к повышенному расходу топлива.A disadvantage of the known system under conditions of variation in the productivity of the unit, determined by the mill operation and other disturbances, is the considerable pressure fluctuations in the welding (especially the lower) zones, which leads to an increase in the intake of air into the furnace, increased metal loss and ultimately increased fuel consumption.

Известна также система регулировани  давлени  в методической печи, содержаща  два контура регулировани . Основной контур регулирует давление воздействием на дымовой шибер, а доПЕЧИAlso known is a pressure control system in a method furnace containing two control loops. The main circuit regulates the pressure by acting on the smoke damper, and doPECHI

полнительный контур регулирует давление путем изменени  расхода топлива на дополнительные горелки одной из зон 2.A complementary circuit regulates the pressure by changing the fuel consumption for additional burners of one of zones 2.

Указанна  система регулировани  давлени  выбрана в качестве прототипа. К ее недостаткам следует отнести наличие перекрестной (двухсторонней) св зи между каналами регулировани  температуры и давлени , взаимно вли кщих друг на друга. Прин та  несв занна  система приводит к снижению качества регулировани  и даже к возникновению незатухающих колебаний этих параметров.This pressure control system is selected as a prototype. Its disadvantages include the presence of a cross (two-way) connection between the temperature and pressure control channels, which mutually influence each other. The acceptance of an unrelated system leads to a decrease in the quality of regulation and even to the occurrence of undamped oscillations of these parameters.

Целью изобретени   вл етс  повышение качества регулировани  путем автономного управлени  давлением и температурой в зоне, оборудованной встречными горелками.The aim of the invention is to improve the quality of regulation by autonomously controlling the pressure and temperature in the zone equipped with opposing burners.
