Abstract

Keksintö on liukusuljinmekanismi sulan metallin virtauksen säätelemiseksi laskukanavaan metallurgisesta uunista tai astiasta. Liukusuljinmekanismissa on uunin tai astian laskuaukon suhteen kiinteästi sovitettavissa oleva vastinlevy ja vastinlevyn suhteen liukumaan sovitettu säätölevy virtauksen säätelemiseksi laskukanavaan. Säätölevyssä on virtauskanavia, joka ovat liuotettavissa vastinlevyn virtauskanavan ja laskukanavan väliin metallin virtauksen säätelemiseksi. Säätölevyssä on myös kaasunsyöttökanavia, jotka käsittävät huokoista materiaalia ja joiden läpi syötetään kaasua liukusuljinmekanismin virtauskanaviin. Keksinnön avulla voidaan laskea ja valaa suhteellisen matalla sulavia metalleja ja niiden seoksia ilman, että metalli jähmettyy laskuaukkoon pidempienkään laskun katkojen aikana. Keksinnön avulla laskettavan tai valettavan metallin suihku voidaan kohdistaa täsmällisesti toivottuun paikkaan ilman roiskeita.&sr;(Kuva)The invention is a slide gate mechanism for regulating the flow of molten metal into a discharge channel from a metallurgical furnace or vessel. The slide gate mechanism has a counter plate that can be fixedly adapted to the discharge opening of the furnace or vessel and an adjustment plate that is adapted to slide relative to the counter plate for regulating the flow into the discharge channel. The adjustment plate has flow channels that can be dissolved between the flow channel of the counter plate and the discharge channel to regulate the flow of metal. The adjustment plate also has gas supply channels that comprise a porous material and through which gas is fed into the flow channels of the slide gate mechanism. The invention makes it possible to cast and pour relatively low-melting metals and their alloys without the metal solidifying in the discharge opening even during longer interruptions in casting. The invention allows the jet of metal to be cast or poured to be precisely directed to the desired location without splashing.&sr;(Image)
