Aluminum profile production enterprises generally realize that it is increasingly difficult for industrial aluminum profiles to survive, develop and grow according to traditional production technology and profit points of enterprises. After more than 20 years of development, a large number of on-site technicians and industrial workers have been trained in the field of building profile production, and rich practical experience has been accumulated. But at present, the technical added value of products is still relatively low. In order to improve the product competitiveness of building materials, we must break through the existing technical bottleneck, and start from the aspects of new product development, improving production efficiency and strengthening process technology control and improvement, so as to improve the core competitiveness of enterprises and products.

Improve the melt quality of aluminum bars: Some aluminum production enterprises often account for about 50% of the product quality problems in the extrusion production process due to insufficient attention to the quality of molten cast products. Combined with the soaking effect, the influence on extrusion speed accounts for about 70%. It is observed that the process control in the melting and casting workshop of most aluminum profile manufacturers is not ideal, and the refining effect of the melt is poor, so the problem of "how to prevent the secondary pollution of the melt after the furnace" has not been paid enough attention.

Improve the design, processing and manufacturing level of dies: At present, most manufacturers of building aluminum profiles in China use single-hole die extrusion, and the application of porous dies is limited to the production of small-section profiles by small-tonnage extruders. For ordinary building profile products, the output of a single section is usually large, and there are many batches. Therefore, the conditions for adopting porous die extrusion are met, which requires the innovative consciousness of die designers, processing equipment and accuracy to reach a new level, thus improving the efficiency of extrusion production. In this respect, there is a big gap between us and our European and American counterparts.

Adopt advanced extrusion technology: At present, individual manufacturers of industrial aluminum profiles adopt this method, which has achieved good results and significantly improved the output of single extrusion machine. Bright Lo, a die expert, believes that on the basis of optimizing die design, improving die material performance and surface treatment effect, the purpose of "low-temperature rapid extrusion" can be achieved by using high-quality aluminum bars after soaking and heating quickly, and the bar temperature can be controlled in a relatively low temperature range under the condition that the extrusion outlet temperature is above 500℃.

Degassing and filtering treatment method of industrial aluminum profiles

Everyone may not know much about the degassing and filtration treatment methods of industrial aluminum profiles. The following Wuxi aluminum profile manufacturers will share them with you:

Any melt treatment, filtration and degassing are complementary, and slag and gas cannot be completely separated. Generally, slag is associated with gas, and the more inclusions, the higher the gas content in the melt, and vice versa. In the degassing process, the inclusions in the melt must be removed at the same time, and the gas content in the melt must be reduced at the same time. Therefore, the combination of degassing and melt is very beneficial to improve the purity of melt. Many degassing devices mentioned above are melt on-line processing devices combining degassing and filtration. This is also the way used by many aluminum processing enterprises to treat aluminum melt online. Therefore, the combination of degassing and filtration online treatment will not be introduced separately here, which needs to be applied by the vast aluminum processing industry according to the quality requirements and production conditions of products. Due to the limited development of in-furnace treatment and purification technology, the major aluminum processing, melting and casting enterprises all over the world focus on the on-line purification technology of melt outside the furnace. Its main development direction is to continuously improve the purity of melt and continu

ously pursue efficient and cheap purification technology to meet the development needs of aluminum processing and melt purification technology.
