von Eisengegenständen.of iron objects.
Bei dem Eintauchen der Eisenwaaren in Bader von geschmolzenem Zinn und seinen Legirungen bilden sich in dem geschmolzenen Metall allmälig grofse Mengen kleiner Metalltheilchen bezw. schwerer schmelzbarer eisenhaltiger Legirungen, welche das, Bestreben haben, zu krystallisiren. Dieselben lagern sich auf die Oberfläche der herausgezogenen Eisen-.'! waaren, krystallisiren beim Erkalten und geben dadurch den Waaren, die anfangs schön glänzend erschienen, allmälig ein mattes, sogar; ein völlig rauhes Ansehen.When the iron goods are immersed in baths of molten tin and its alloys, large quantities of small metal particles or metal particles are gradually formed in the molten metal. more difficult, fusible, ferrous alloys which tend to crystallize. These are deposited on the surface of the extracted iron. '! were, crystallize when they cool, and thereby gradually give the goods, which at first appeared beautifully shiny, a dull, even ; a completely rough appearance.
Aus diesem Grunde ist es nöthig geworden, in den Weifsblechfabriken die Eisenbleche in drei bis fünf nach einander folgende Zinnbäder einzutauchen, von denen jedes folgende Bad immer reiner bezw. freier von eisenhaltigen Zinnlegirungen ist. For this reason it has become necessary the iron sheets in the white sheet factories to immerse in three to five consecutive tin baths, each of which is consecutive Bathroom always purer and is free from iron-containing tin alloys.
Diese schwerer schmelzbaren Legirungen werden aus dem Bade leicht entfernt durch Eintauchen hinreichend kalter Körper j am besten mittelst Durchleitung kalter Flüssigkeiten (tropfbarer oder gasförmiger), wodurch diese Legirungen zur Erstarrung gebracht und abgeführt werden. Nach Beseitigung derselben liefert das Bad wieder schön glänzende Ueberizüge. These alloys that are more difficult to melt are easily removed from the bath by immersing sufficiently cold bodies best by means of conduction of cold liquids (drippable or gaseous), whereby these alloys are solidified and removed. After eliminating the same the bathroom provides beautifully shiny covers again.
; Es wird zu diesem Zwecke in dem Bade iein U-förmiges Rohr, welches am besten von kaltem Wasser durchströmt wird, so lange hin- und herbewegt, bis die zur Krystallisation geneigten und leichter erstarrenden Metalltheilchen sich hinreichend an das Rohr festgesetzt haben; mit dem Herausziehen des Rohres aus dem Bade werden diese schadr liehen Theile völlig aus demselben entfernt.; It is used for this purpose in the bath ie a U-shaped tube, which is best made of cold water is flowed through, moved back and forth until the crystallization inclined and more easily solidified metal particles have sufficiently attached themselves to the pipe; with pulling out the If they come out of the bath, these will be damaging borrowed parts entirely removed from it.
