近年来,铝合金生产中,有要求生产(?)80～112毫米圆铸锭的趋势,其根据是可以节省大水压机、提高成品率,也就是一般所谓的一次挤压。但实际上还有不少工厂采用大铸锭经挤压成挤压毛坯,再送去挤压成所需的挤压制品。在我国今后铝工业的生产建设中,究应采用哪种生产工艺,尚未统一认识。这里,特根据我国的生产实际,加以分析研究,提出我们的意见同决策机关和广大同志商讨。我们认为生产小直径圆铸锭不仅机械性能不易满足现代工业要求,而且生产成本较高。
In recent years, aluminum production, there is a requirement to produce (?) 80 ~ 112mm round ingot trend, based on the hydraulic press can save big, improve the yield, which is the so-called one-time extrusion. However, in fact, there are still many factories using a large ingot extruded into extruded rough, and then sent to squeeze into the required extruded products. In our country’s future production and construction of aluminum industry, research should adopt what kind of production technology, not yet unified understanding. Here, Te according to our country’s actual production, to analyze and research, put forward our opinions with the decision-making organs and the majority of comrades to discuss. We believe that the production of small diameter round ingot is not only difficult to meet the modern industrial requirements of mechanical properties, and higher production costs.
