    This invention relates to rolling production. The purpose of the invention is to prevent surface cracking. The invention can be used in a line of a casting-rolling unit containing a continuous casting machine with a rotary mold made according to the Propecia method, from which the cast trapezoidal section goes into a rolling mill where it is crimped in two stages. At the first stage of deformation of the cast billet, a shell of small evenly distributed recrystallized grains is formed on its surface by total reduction of 5–20% in a system of mutually perpendicular calibers: vertical ellipse — horizontal ellipse — circle. This shell allows a significant reduction in the cross sectional area of the CO in the second stage without cracking the cast billet even with a high content of other impurities like lead, bismuth and antimony. oh h SP

    The invention can be carried out 5 but in the line of a casting and rolling unit containing a continuous casting machine with a rotary mold made according to the Properzi method, from which the cast billet of trapezoidal section is fed to the rolling mill.
    The essence of the method lies in the fact that during the initial deformation of the cast billet, a shell is formed on its surface 15 of fine uniformly distributed recrystallized grains. A shell of fine grains in a cast billet is formed with a total reduction of 5-20% in a system of mutually perpendicular gauges: vertical ellipse - horizontal ellipse - circle. This shell allows a significant reduction in cross-sectional area in the second stage of deformation without cracking the cast billet, even with a high content of impurities such as lead, bismuth, iron and antimony. thirty

    cm 112 Invention relates to rolling production. The aim of the invention is to prevent surface cracks. The invention can be carried out in a line of a casting-rolling unit containing a continuous casting machine with a rotary mold made according to the Propecia method, from which the trapezoidal section is cast into a rolling mill. The essence of the method lies in the fact that during the initial deformation of the cast billet, a shell is formed on its surface from small evenly distributed recrystallized grains. A shell of small grains in the cast billet is formed with a total reduction of 5-20% in the system of mutually perpendicular Rnj calibers: a vertical ellipse - a horizontal ellipse - a circle. This shell allows a significant reduction in the cross-sectional area in the second deformation stage without cracking the cast billet even with a high content of such impurities as lead, bismuth, iron and antimony. The parameters of the proposed method: The temperature of the melt With 1100-1120 flared copper in the ladle, The temperature of the cast billet at the entrance to the rolling mill, ° C 870-890 Speed of the rotary crystallizer, m / min 12 Area of the cast billet, cm 31 Reduction of the area of the cast billet during primary deformation, % 5-20 Reducing the area of the workpiece in the second stage of deformation,% Not less The degree of relative reduction in the second stage of deformation is determined by reducing the number of rolling mill stands and ensuring the required productivity. Claim method of rolling copper rod from non-uniform cast billet, including primary deformation in a system of two mutually perpendicular calibers and deformation on a final size, characterized in that in order to prevent cracks by forming a shell of small evenly distributed recrystallized grains on the surface of the rod , the total value of the relative reduction during primary deformation is 5–20%.
