Description
Schlackenwolle enthaltende Formmasse für Dauergießformen. Gußformen aus feuerrfesten Steinen für das Gneß'en von Metall sind bereits ]bekannt, jedoch haben sie den Nachteil, daß sie bei hohen Temperaturen, wie sie rfür das @Gieß-en von Eisen und Stahl erforderlich sind, nur kurze Zeit halten oder daß,das flüssige Eisen anbackt, .so,daß sie oft nur einmal zu verwenden sind. Auch iSchladkenwolle ist als B'estandteil von Fornn'rnassen schon verwendet worden. Hier waren .jedoch die Formen nur für Guß von niederer Temperatur .bestimmt.Molding compound containing slag wool for permanent casting molds. Molds from refractory stones for the casting of metal are already known], however they have the disadvantage that they are used at high temperatures, such as those used for @gieß-en of iron and steel are required to hold only a short time or that, the liquid Iron caked on, so that they can often only be used once. Also iSchladkenwolle has already been used as a component of molds. Here were the molds are only intended for low-temperature casting.
Die aus der nachstehenden Mischung hergestellten Formen eignen sich dagegen vorzüglich,für ;Stahl- und Roheisenblöcke, da sie eine außerordentlich lange Lebensdauer halben und ein Ansetzen des flüssigen Materials nicht stattfindet. Auch kann die Masse immer wieder verwandt werden.The shapes made from the mixture below are suitable on the other hand excellent for steel and pig iron blocks, as they are extraordinarily long Half the life and a build-up of the liquid material does not take place. Even the mass can be used again and again.
Die der Erfindung entsprechende Masse besteht aus gemahlenen alten Schamottsteinen (4o Prozent), Schamotte (3o Prozent), Abfällen von 'Schlackenwolle =(3o Prozent).The mass corresponding to the invention consists of ground old Fireclay bricks (4o percent), fireclay (3o percent), waste of slag wool = (3o percent).
Zur Herstellung der Form werden sämtliche Bestandteile mit wenig Wasser vermischt, ,gut. durchgefeuahtet und darauf in die Gießform eingetragen und mit Hilfe des Modelles in die richtige Form gebracht.To produce the mold, all the components are mixed with a little water mixed,, good. durchgefeuahtet and then entered into the mold and with With the help of the model, brought into the right shape.
Darauf wird,die Form an der Luft getrodcnetund ungefähr 24 Stunden,im Trockenofen nachgetrocknet. Nachdem die Form noch seit Schwärze ausgestrichen ist, :ist sie ,gebrauchsfertig. Nach Entfernung des gegossenen Metallibloökes wind die Form mit Lehmwasser ausgebürstet ,und ist wieder gebrauchsfertig. Beim Entfernen -des Gußibdockesdarf die Form nicht durch Hammerschläge erschüttert werden.The shape is then trodcnet in the air for about 24 hours Drying oven after drying. After the shape has been smeared out since blackness, : it is, ready to use. After removing the cast metal block, the The mold is brushed out with clay water and is ready for use again. When removing -of the Gußibdockesmust not be shaken by hammer blows.
