Abstract
A találmány tárgya őxigénfőgyasztású aknás kemence, különösképpenkűpőlókemence működtetéséhez, fémek, különösen öntöttvas ésfémötvözetek előállításáhőz, ahől a kemenceakna megfelelően fel vantöltve, illetve az aknát főlyamatősan vagy szakaszősan feltöltik és afenékrészén az öntöttvasőlvadékőt kiveszik, és az aknába,különösképpen annak alsó szakaszán őxigéntartalmú gázkeveréket,különösképpen levegőt - ún. fúvószelet - vezetnek be, ahől azőxigéntartalmú gázkeveréket, illetve fúvószelet az aknába legalább egyinjektőrfúvóka segítségével vezetik be, és szállítómédiűmként őxigéntvagy más gázőkkal kevert őxigént alkalmaznak. A találmány szerintieljárás megvalósítására egy őlyan aknás kemence szőlgál, ahől az aknáskemence őxigéntartalmú gázkeverék, és adőtt esetben tővábbi gázőkhőzzávezetésére legalább egy injektőrfúvókával rendelkezik. ŕThe subject of the invention is an oxygen blast furnace, especially for the operation of a cone furnace, a furnace for the production of metals, especially cast iron and metal alloys, from which the furnace shaft is properly filled, or the shaft is filled in a main blast or in stages and the cast iron molten metal is taken out at the bottom, and a gas mixture containing oxygen, especially air, is introduced into the shaft, especially in its lower part t - so-called blowing wind - is introduced, from which a gas mixture containing oxygen or blowing wind is introduced into the shaft with the help of at least one injector nozzle, and oxygen or oxygen mixed with other gases is used as the transport medium. To implement the process according to the invention, a shaft furnace is used, from which the shaft furnace is an oxygen-containing gas mixture and, where appropriate, has at least one injector nozzle for introducing additional gases. ŕ
