Copper is a unique chemical element which is used since ancient times due to its universal chemical properties. By means of the method of continuous founding, hundreds of items of rod-like billets of different cross-section shapes are manufactured from copper. The problem of production of defect free copper wire rods is important nowadays, because the market of cable products still increases. As the deposits of cooper ore in the nature are being exhausted, the processing of copper scrap becomes of still growing interest for non-ferrous metallurgy. There emerged the necessity of further study and improvement of the technology of production of copper wire for electrical engineering and that of copper wire rods. In manufacturing of copper wire rods according to the method of continuous founding, there emerge violations of technological process because of formation of hot cracks in a cast billet. Just for this reason, in this article, such problems are described, and ways of their solving are considered. The character of their structure formation during crystallization of copper wire rods is analyzed. Advantages and drawbacks of the method of continuous founding of copper wire rods are described. The possibility of the use of ultrasonic oscillations for improvement of the quality of finished products is shown.
