Casting production is the cheapest way of manufacturing semi-finished and/or finished products. Disadvantages of the castings obtained by this method are both their dimensional accuracy and properties that are significantly inferior to those of products obtained by metal forming methods. Therefore, the development of new technologies, settings and casting equipments that would provide castings with the structure, and hence, properties being similar or superior to those of deformed ones, is an urgent task. One way to improve the processing parameters of casting production is the crystallization of melts under the influence of external factors. So, the use of ultrasound, electromagnetic field and vibration leads to an improvement in alloy mechanical properties. However, these methods of producing cast parts which ensure improved mechanical properties do not allow the manufacture of longer billets. In industries, particularly in aircraft manufacturing, the production of long billets with high mechanical properties for a short production cycle is an important production scientific and technical task. The purpose of this work is to create regimes for obtaining such products by the continuous casting method on the device developed by the authors. To achieve the goal, the following tasks have been accomplished: the design of the crystallizer has been developed, which enables to produce semi-finished products with longer length; the technological parameters of the new casting method has been optimized; the structure and properties of manufactured products are studied. The results of research of metal products from the known aluminum alloy AD1, obtained by the method of continuous horizontal casting, combined with deformation of the melt, are presented. The scheme of the crystallizer with movable walls developed at the Institute of Engineering Science and Metallurgy is presented.
The work was carried out at the Institute of Engineering Science and Metallurgy of the Far Eastern Branch of the Russian Academy of Sciences with the advice of the NUST “MISiS” on the basis of the technical task of the Skolkovo Innovation Center as part of the research on microgrants.
