Abstract

Patente de Invenção: <B>"PROCESSO PARA DETECçãO E REGULAGEM DA ALTURA DO NìVEL DE ENCHIMENTO DO METAL LìQUIDO EM UMA LINGOTEIRA"<D>. A invenção refere-se a um processo e a um dispositivo para detecção e regulagem da altura do nível de enchimento da fusão metálica, que se encontra em uma lingoteira, particularmente para uma instalação de fundição por extrusão para aço, que pode ser alimentada à lingoteira através de um tubo de imersão de um recipiente de alimentação, que apresenta uma abertura de fundo fechável, com um elemento de medição, que pode ser introduzido de modo verticalmente deslocável no espaço livre da lingoteira. Nesse caso, o elemento de medição de nível de enchimento (42) está unido através de um primeira linha de sinais (31) com um computador (41), que através de uma primeira linha de controle(51) está em ligação com um primeiro atuador (61), no qual está fixado um braço (71), em cuja extremidade superior está montado o elemento de medição de nível de enchimento (42). No braço (71) está previsto um sensor de medição de posição (43), que através de uma segunda linha de sinais (32) está unido com o computador (41), que através de uma segunda linha de controle (52) está em ligação com um segundo atuador (62), que está ligado com um órgão de fechamento (81), para fechamento da abertura de fundo (12) do recipiente de alimentação (11).Invention Patent: <B> "PROCESS FOR DETECTING AND ADJUSTING THE HEIGHT OF THE FILLING LEVEL OF THE LIQUID METAL IN A LANGUAGE" <D>. The invention relates to a process and a device for detecting and regulating the height of the fill level of the metal melt, which is found in an ingot mold, particularly for an extrusion casting plant for steel, which can be fed to the ingot mold through an immersion tube of a feeding container, which has a closed bottom opening, with a measuring element, which can be inserted vertically displaceable into the free space of the mold. In this case, the level measurement element (42) is connected via a first signal line (31) with a computer (41), which is connected via a first control line (51) to a first actuator (61), to which an arm (71) is attached, on whose upper end the level-level measuring element (42) is mounted. A position measurement sensor (43) is provided on the arm (71), which is connected to the computer (41) via a second signal line (32), which is connected via a second control line (52). connection with a second actuator (62), which is connected with a closing member (81), for closing the bottom opening (12) of the supply container (11).
