Description

Verfahren zur Verhinderung des Aneinanderhaftens von mit einem anorganischen Stoff isolierten Eisenblechen beim Glühen in Paketen In dem Patent 716962 ist ein Verfahren angegeben, um mit einem Isolierüberzug aus anorganischem Stoff versehene Bleche beim Glühen in Paketen vor dem Aneinanderhaften zu bewahren, indem man sie mit einem überzug aus einer Zucker-, Stärke- oder Dextrinlösung versieht.Method for preventing the sticking of an inorganic one Fabric insulated iron sheets when glowing in packages In the patent 716962 is a Method specified for provided with an insulating coating made of inorganic material Keep baking sheets from sticking together when they are glowing in packets covered with a sugar, starch or dextrin solution.

Die Erfindung stellt eine weitere Verbesserung dar, die darin besteht, daß das überzugsmittel nicht in flüssiger, sondern in feinkörniger Form auf die noch feuchte Isolierschicht .aufgebracht wird. Die Blechpakete sind dann nach dem Trocknen* zum Glühen ohne neuerliches Eintauchen in eine Lösung bereit, so daß die Zeit des Zwischentrocknens erspart wird.The invention represents a further improvement, which consists in the fact that the coating agent is applied to the still moist insulating layer, not in liquid, but in fine-grained form. The sheet metal stacks are then ready for annealing after drying * without being immersed again in a solution, so that the time of intermediate drying is saved.
