Checking
the Braze at the Furnace Exit |
|||
Part was overheated. A row of airways was crushed leaving another row loose. The loose row then falls out. To remedy this situation, you need to run the tracker through. See how much the part is overheated and reduce the temperature or increase the belt speed. If there are no crushed fins, it is likely that you have a temperature dip somewhere in the furnace. Run the tracker through the furnace. The dip, if there is one, will show up clearly. The bend radius of the serpentine extrusion might be too large. Fins are loose going into the furnace in localized areas and will drop in these areas. Fixtures could be bowed. Chick the fixtures with a straight edge or height gauge. Remember that fixtures have a life and should be replaced from time to time.
