You may encounter some problems during the process of insulating aluminum coils. These problems have troubled many friends. Today are two more common questions for everyone to answer.
First: The insulated aluminum coil formed a little deformation after processing. Why did the insulated aluminum coil I bought on the market suddenly deform after one or two days of processing?
Answer: Perfect pre-stretching eliminates internal stress processing, completely eliminates internal stress, and will not warp, crack, and deform during processing and stress.
Two: We are in the process of manufacturing insulation aluminum molds. One of the headaches is that after most of the processing is completed, we suddenly find sand holes or unknown impurities on the polished surface, and now the workpiece is scrapped.
A: Ensure the unique grain refinement process, all through aerospace use of ultrasonic detection of aluminum alloy products, sand holes, streaks, bubbles and impurities. The heat treatment technology of aluminum products has excellent volume, thickness (or diameter) 300mm, and the strength and hardness can be consistent. There are very few computers controlling the entire production process, making human errors possible, and performance can be guaranteed by producing different batches.
Of course, insulated aluminum coils not only have these two problems in this process, this requires everyone to see more in their daily work, and requires more and more learning and summary to avoid problems. Even if there are problems, they can be Solved soon
Frequently asked questions about aluminum coils include the following:
Air strips and slag inclusions: It may be caused by factors such as the production process is not strictly implemented, the degassing outside the furnace is not in place, the aluminum water treatment is not in place, the filtration effect is not obvious, the air moisture is too heavy and other factors.
Long strips of small cracks: may be caused by damage or damage to the chewing skin.
Black bars: It may be caused by poor process execution and poor aluminum water treatment.
Scratches: It may be caused by the friction between the lower table of the shearing machine and the surface of the aluminum plate.
Composite layer peeling off: Irregular defects caused by the aluminum-clad layer of composite materials leaving the matrix and falling off.
Embossing: Due to strip wrinkles, strip breaks, etc., irregular color differences on the roll surface are periodically printed on the strip surface during the rolling process.
