Claims (1)
где dl1= mах[dlA, dlB] dl2= min[dlA, dlB] dg1= mах[nAdAA, nBdAA] dg2= min(nAdAA, nBdAB] m = min[nA, nB] к, 1 = целые числа, так что знаменатель λL и λQ минимален d1 = расстояние между двумя пятнами в направлении по окружности валка (которое является продольным направлением прокатки листа или полосы) dg = расстояние между двумя пятнами в осевом направлении валка между двумя окружными линиями пятен (которое является поперечным к направлению прокатки) = ndА dА = расстояние между двумя окружностями в осевом направлении n = количество витков по поверхности валка до того как кратер будет иметь то же самое окружной положение на валке, h является целочисленным множителем А = первый текстурированный рабочий валок В = второй текстурированный рабочий валок
2. Способ производства металлических листов или полос по п. 1, отличающийся тем, что оба текстурированных рабочих валка состоят из пары рабочих валков в любой клети тандем-стана.1. A method of manufacturing metal sheets or strips by rolling a metal sheet or strip in cold rolling mills, characterized in that at least two work rolls are textured in accordance with a surface pattern consisting of a regular deterministic two-dimensional structure in the form of unit cells or spots, mentioned the spots are obtained by treatment with an electron beam and the fact that the interference wavelength λ L in the longitudinal direction of the roll and the interference wavelength λ Q in the transverse direction and the rolls are less than 1.5 mm, and λ L and λ Q are defined as follows
where dl 1 = max [dl A , dl B ] dl 2 = min [dl A , dl B ] dg 1 = max [n A dA A , n B dA A ] dg 2 = min (n A dA A , n B dA B ] m = min [n A , n B ] k, 1 = integers, so that the denominator λ L and λ Q is minimal d1 = the distance between two spots in the direction around the circumference of the roll (which is the longitudinal direction of rolling of a sheet or strip) dg = distance between two spots in the axial direction of the roll between two circumferential lines of spots (which is transverse to the direction of rolling) = ndА dА = distance between two circles in the axial direction n = number of turns on the surface of the roll before ater will have the same circumferential position on the roll, h is an integer multiple of A = the first textured work roll B = the second textured work roll
2. A method of manufacturing metal sheets or strips according to claim 1, characterized in that both textured work rolls consist of a pair of work rolls in any stand of the tandem mill.
