Description

KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Bisher geschah das Abkühlen der Heizzüge und -gase in Martinöfen dadurch, daß der Gas- und Luftzutritt teilweise oder ganz gesperrt wurde. Es trat dadurch wohl eine Verminderung der Heizgase, aber keine direkte Kühlung derselben und der Heizkanäle ein, so daß zur Abkühlung eine längere Zeit erforderlich war.So far, the cooling of the heating flues and gases in Martin ovens has been done by the gas and air access has been partially or completely blocked. As a result, one probably occurred Reduction of the heating gases, but no direct cooling of the same and the heating channels, so that it took a long time to cool down.

Dieser Übelstand soll durch die vorliegendeThis evil is intended by the present

ίο Erfindung vollständig beseitigt werden, indem man die Luftzüge, ähnlich wie es bei Darren und dergl. schon geschehen ist, mit Kanälen a und b versieht, die direkt ins Freie führen und mit der kalten Außenluft in Verbindung treten, wenn ihre Schieber oder Klappen c geöffnet werden.ίο invention can be completely eliminated by providing the drafts of air, similar to what has already happened with Darren and the like, with channels a and b that lead directly into the open air and come into contact with the cold outside air when their sliders or flaps c be opened.

Hierbei wird die heiße Luft, deren Zufuhr entsprechend geregelt werden muß, durch die gegebenenfalls unter Druck eintretende kalte Luft gekühlt, und die Abkühlung der heißen Kanäle und der Gase wird unmittelbar und plötzlich bewirkt, so daß die Temperatur des Gemisches von Gas und Luft in dem Ofen bedeutend sinkt und der zu heiße Gang ~ sehr schnell auf die gewünschte Temperatur gebracht wird.Here, the hot air, the supply of which must be regulated accordingly, through the if necessary, cold air entering under pressure is cooled, and the cooling of the hot air Channels and the gases is immediately and suddenly caused so that the temperature of the Mixture of gas and air in the furnace decreases significantly and the too hot aisle ~ is brought to the desired temperature very quickly.
