[0002] Aluminum extrusion technology is a plastic processing method that extrude aluminum alloy billets through a die orifice of a specific shape to form the desired cross-sectional shape and size. This technology is widely used in many fields such as construction, transportation, and electronic appliances to produce aluminum profiles with various complex cross-sections.

[0003] With the continuous advancement of industrial manufacturing technology, aluminum extrusion products are widely used in aerospace, automobile, construction and other fields due to their light weight, high strength and good corrosion resistance. Especially in occasions where precise temperature control is required, such as heat treatment, mold processing and precision assembly, the importance of temperature control becomes more and more prominent. Therefore, segmented temperature control technology is widely used in the extrusion molding process of aluminum products, and its role in the extrusion molding process of aluminum products is also very important. Through segmented temperature control technology, the aluminum products can achieve the ideal plasticity and deformation ability during the processing process, and reduce the forging defects caused by temperature fluctuations.

[0004] However, during the aluminum extrusion production process, aluminum is extruded at high temperatures. However, as the production process progresses, dirt and carbon deposits will form on the inner wall of the extrusion barrel due to the oxidation of the aluminum alloy, residual substances, and the high-temperature working environment. These dirt not only affects the surface quality of the aluminum, but may also cause the heat conduction efficiency of the equipment to decrease, increase energy consumption, and shorten the service life of the equipment.
