Description

Verfahren zur Herstellung von ummantelten Schweißelektroden Bei der Herstellung von ummantelten Schweißelektroden wurde es bisher als sehr nachteilig, insbesondere als zeitraubend empfunden, daß die Elektroden nach Verlassen der Presse zunächst etwa 24 Stunden an der Luft getrocknet werden mußten und erst danach in einem besonderen Trockenofen bei erhöhten Temperaturen fertig getrocknet werden konnten. Ein derartiger Trockenprozeß war deswegen erforderlich, da beim schnellen Trocknen der ummantelten Elektrode, unmittelbar nach Verlassen der Presse, ein Aufreißen der Ummantelung erfolgte. Dieser langwierige Trockenprozeß hatte es bisher unmöglich gemacht, eine Bandfertigung bei der Herstellung von ummantelten Schweißelektroden einzuführen. Gemäß der vorliegenden- Erfindung werden diese Nachteile ,dadurch beseitigt, daß die ummantelten Elektroden unmittelbar nach Verlassen der die Ummantelung herstellenden Presse mit einem Überzug aus Wasserglas versehen werden. Dies kann durch Tauchen, besonders vorteilhaft jedoch durch Spritzen mittels einer Ringstrahldüse unmittelbar nach dem Verlassen des Preßmundstückes erfolgen. Danach werden die Elektroden einem starken Trockenprozeß unterworfen, indem sie beispielsweise durch eine kurze Trockenkammer, die besonders stark erhitzt ist, durchlaufen. Die Beheizung der Trockenkammer kann je nach den Verhältnissen mit Gas, Dampf oder elektrisch erfolgen. Der erfindungsgemäße Überzug mit Wasserglas ermöglicht die sofortige schnelle Trocknung, ohne daß hierbei Risse an der Ummantelung der Elektroden auftreten. Es ist demnach möglich, ummantelte Schweißelektroden in Bandfertigung herzustellen:Process for the production of coated welding electrodes Production of jacketed welding electrodes has so far been considered very disadvantageous in particular found to be time consuming that the electrodes after leaving the press first had to be air-dried for about 24 hours and only then in ready to be dried in a special drying oven at elevated temperatures could. Such a drying process was necessary because of the rapid Drying of the coated electrode, immediately after leaving the press, tearing open the sheathing took place. This lengthy drying process has so far been impossible made a tape production in the manufacture of coated welding electrodes to introduce. According to the present invention, these disadvantages are eliminated by that the coated electrodes immediately after leaving the one producing the coating Press can be provided with a coating of water glass. This can be done by diving, particularly advantageous, however, directly by spraying by means of a ring jet nozzle after leaving the press mouthpiece. After that, the electrodes are one subjected to a strong drying process, for example through a short drying chamber, which is particularly strongly heated. The heating of the drying chamber can be carried out with gas, steam or electric, depending on the conditions. The inventive coating with water glass enables immediate quick drying without cracking occur on the coating of the electrodes. It is therefore possible to sheathed Manufacture welding electrodes in strip production:
