According to the Northwest Aluminum Processing Plant, the plant is focused on high-end development of new products. In March, it successfully produced a high value-added, high-quality special extruded section.
Since the beginning of this year, Northwest Aluminum has actively implemented the strategic deployment of Chinalco's “developing products to the high end of the value chain and the front end of the product chainâ€, and has determined several types of leading products with high-value-added finishing, and on this basis, it has continued to promote high-precision products. R & D, and constantly expand the high-end products and sophisticated.
It is understood that this kind of high-quality special extrusion profile alloy is very demanding, and the appearance size and mechanical properties are demanding, and the sectional structure is complex. In the initial stage of trial production, it is easy to cause mold blockage, uneven wall thickness, large dimensional change, and twisting. Serious phenomenon. In response to the problems in the trial production process, Northwest Aluminum promptly organized expert technicians to attend production, observe and study on site, record and collect data, analyze and summarize, and find the best by adjusting a series of parameters such as ingot temperature, extrusion speed, and ingot length. Production process standards. At the same time, the technical team also optimized the mold design and mold repair quality, adjusted the mold working belt width and die hole size, mastered the influence of the die working belt width, die hole size and mold temperature on the extruded profile during the extrusion process, and found the most Good mold structure, installation of equipment at the front of the extruder eliminates distortion defects.
In the trial production process of more than two months, Northwest Aluminum R & D team tried more than 20 times, repaired the mold more than 30 times, and finally successfully trial production at the end of March to achieve mass production. After delivery to users in early April, the user affirmed the quality of the new product and signed a follow-up contract. At present, Northwest Aluminum is actively organizing production.
Wire brushes are often used for cleaning and derusting various materials, such as surface treatment of steel and aluminum, or cleaning and derusting of industrial pipelines and mechanical screw holes.
Wire brushes are classified into wood handle wire brushes, flat wire brushes, spring wire brushes, wire brush rollers, etc
