1. In the process of producing aluminum profile products, dust and impurities on the aluminum bar should be cleaned after cutting, and air duct can be used to reduce the sources of slag inclusion and black dragging. Aluminum aging furnace has not been produced for a period of time to carry out cylinder cleaning.
2. There should be a certain thickness of residual pressure, not too thin, because too thin residual pressure will lead to the aluminum bar involved in the end of the profile, forming slag inclusion and dragging black phenomenon, making it a waste product.
3. Check the aging furnace equipment of Shanghai aluminum material before use, and make standard adjustment. For example, if the extrusion rod is not aligned, it will lead to a series of adverse phenomena, so it is necessary to center it from left to right as soon as possible; moreover, the pressing block should be regularly inspected and replaced, and the barrel will be deformed after a long time of use, so attention should be paid to replacement.
