Description
Odlewanie latwo tiopnych metali jak glin, oilów, cynk, cyna i ich stopów ze stoja¬ cych lub wywrotowych zbiorników topiel¬ nych o bocznym Mb dolbym spuscie, przeszkadza i powoduje silne utlenianie me¬ talu w rynnie lub rurze wyplywowej.Przedmiotem wynalazku jest urzadzenie pozwalajace skutecznie uniknac niepozada¬ nego utleniania meftalu w spuscie zbiorników tonalnych przy odlewaniu na wolnem po¬ wietrzu w ten isposób, ze przez; spust ten przeprowadza sie w czasie odlewania gaz obojetny lub rediukiuljacy.Wykonanie takiegp urzadzenia w mysl wynalazku, przedstawione jest na rysunku.Rura / przechodzaca pnzeiz boczna sciane, np. tygla, jest nieruchomo polaczona z o- prawa zaworu 2, znajdiujacego siie w runze ochronnej 3. Wewnatrz oprawy zaworu znajduje sie stozek zaworowy 4, porusizany przy pomocy kólka 5. Aby zapobiec utle¬ nianiu wyplywajacego metalu przez rure 1, do rury tej wprowadza sie rura 6 gaz o- chronny, który wypycha z rury / powietrze.Gaz ochronny mozna doprowadzac nie przez rure 6, a przez wydrazenie 7 w zaworze i rurke 8 na rurze 3. W tym przypadku wrze¬ ciono zaworu ufczlczelnia sie dlawikiem, u- mieszczonym pod kólkiem 5. Jezeli gazem ochronnym jest gaz palny, np. gaz z pieców koksowych, generatorowy i t lochronny mozna zapalac na zewnetrznymkoncu rury spustowej, wskuitek czego do¬ plyw tego gaiziu daje sie regulowac sila jego promienia. Wmzy poisiolcy zapalnika 9, o trwalym plomieniu, mozna tein gaz zapalac wówczas, gdy jqgo plomien zostal zgaszony przez wyplywajacy metali. Przy uizyciiu ga¬ zów niepalnych jak azotu, bezwoidinika we- gloweigo i t. di., zbednem jest urzadzanie za¬ palnika. PLThe casting of easily thiopal metals such as aluminum, oils, zinc, tin and their alloys from standing or inverting melting tanks with a lateral discharge, obstructs and causes strong oxidation of the metal in the gutter or discharge pipe. The subject of the invention is a device that allows to effectively avoid the undesirable oxidation of mephthal in the drain of the tonal tanks when pouring out in the open such that by; This trigger is carried out during pouring an inert gas or a reductive gas. The implementation of such a device in accordance with the invention is shown in the drawing. A pipe / passing through a side wall, e.g. a crucible, is fixedly connected to the right of the valve 2, which is in the protective circle 3. Inside the valve holder there is a valve cone 4, moved by a wheel 5. In order to prevent oxidation of the flowing metal by the pipe 1, a protective gas pipe 6 is inserted into this pipe, which pushes the pipe / air out of the pipe. not through pipe 6, but through conduit 7 in the valve and pipe 8 on pipe 3. In this case, the spindle of the valve is sealed with a gland, located under the wheel 5. If the protective gas is a combustible gas, e.g. gas from coke ovens The generator and the ground cover can be ignited at the outer end of the downpipe, so that the flow of this pipe can be regulated by the force of its radius. The fuse 9 with a permanent flame may also be ignited when its flame has been extinguished by the flowing metals. When using non-flammable gases such as nitrogen, carbon dioxide, etc., it is unnecessary to arrange the burner. PL
