Изобретение отдюситс к области чер;ной металлургии, ко«|кретнее, « управлению продувкой металла в подовых сталеплавильных печах.The invention is devoted to the field of ferrous metallurgy, to the "more severe" control of metal blowing in hearth steel-smelting furnaces.
Известны способы упраълеии продувкой металла в подовых сталеплавильных печах путем иэмейани глубины реакционной зоны и состава дуть . Из1весте1Н также ко нтроль запыленности отход щих газов лодовых печей.Known methods of controlling the blowing of metal in hearth steel-smelting furnaces by imeiiani the depth of the reaction zone and the composition of the blow. Izveste1N also controls the dust content of the flue gases of the furnaces.
Цель изобретени - у.меньшить угар железа в ды.м. Это достигаетс тем, что при увеличении содержа1Ни пыли в отход щих газах выще допустимого прадела снижают глубину реакционной зоны и содержание кислорода в дутье.The purpose of the invention is to reduce the waste of iron in the hole. This is achieved by increasing the content of dust in the exhaust gases above the permissible rule, reducing the depth of the reaction zone and the oxygen content in the blast.
Запылеиность отход щих газов -контролируют с помощью, «аиример фотопылемера, измер ющего осла1бл0ние луча света ири пересечении потока газов.The dust content of the exhaust gases is monitored with a help of a photo pollen meter that measures the weakening of the light beam and the intersection of the gas flow.
Глубину реа1кциопной зоны измен ют неремещепие .м фурмы, пзменениелг расхода дуть или изменением угла наклона сопл фурмы относигельно поверхности ванны.The depth of the reversal zone is changed by non-displacement of the tuyere, flow rate blowing or by changing the angle of the nozzle of the tuyere relative to the bath surface.
Предлагаемый способ позвол ет эффективно снижать угар железа без чрезмерного увеличен и длительности продув-ки.The proposed method allows to effectively reduce the waste of iron without excessively increased and the duration of the purge.

Способ управлени продув-кой металла в подовых сталеплавильных печах, включающий измерение содержани пыли в отход щих газах, из:менение глубины реа.кционной зоны и состава дуть , отличающийс тем, что, с целью уменьщени угара железа, при увеличении содержани пылн в отход щих газах выще допустимого предела снижают глубнну реакционной зоны и содержание кислорода в дутье.A method for controlling the purging of metal in hearth steel-smelting furnaces, including the measurement of the dust content in the exhaust gases, from: changing the depth of the reactive zone and the composition of the blowing, characterized in that, with the aim of reducing the iron loss, with increasing dust content in the waste gases above the permissible limit reduce the depth of the reaction zone and the oxygen content in the blast.
