B. Heizkörper, Dampf- und Pumpen-   zylindor, unbrauchbar wird.

  Method for preventing slag and sand from flowing into the mold with the casting metal.



   As is well known, when pouring intricately designed hollow castings made of cast iron, cast steel and metal, considerable scrap is obtained because, despite extreme caution, slag from the pouring ladle into the pouring trough, and molding sand removed from it with the slag through the pouring hole into the sand mold, which causes the pouring - Piece porous and for various purposes, namely z. B. radiators, steam and pump cylinders, becomes unusable.
 EMI1.1
 an iron, steel or metal sheet operated with petroleum, which reaches a few centimeters over the edge of the hole.

   The kerosene is supposed to prevent the transfer of impurities, in particular oxides, from the abdomen into the liquid metal.
 EMI1.2
 specific gravity to reach the surface of the melted material so that they can be skimmed off.



   While the impurities are being skimmed off, the cover plate melts
 EMI1.3
 The head of the casting remains.
