CS237760B1 - Method of rolling rectangular blanks - Google Patents

Abstract

The method of rolling rectangular blanks includes shaping the initial blanks in multi-cavity diagonal sizing rolls, consisting of several blanks connected by loops with the thickness of the loops being brought to a value equal to 0.02 to 0.25 of the width of the narrower edge of the blanks, with their further longitudinal division by mutual lifting of the blanks and final shaping. A characteristic feature of this method is that rectangular blanks with an aspect ratio equal to 0.75 to 0.1 and with one of the diagonals positioned close to the horizontal are shaped in multi-cavity sizing rolls, the division is carried out by rolling in smooth rolls, and the final shaping of blanks with a given aspect ratio is carried out by drawing wide blanks in the same rolls.

SUBJECT INVENTION A method of rolling rectangular blanks, comprising forming a precursor in multi-cavity diagonal calibrations, consisting of several blanks connected by loops with a thickness of 0 to 0.25 to 0.25 widths of the narrower edge of the blanks, with a longer longitudinal distribution of the blanks shaping, characterized in that, in order to simplify the process of separating and unifying the calibration of the rolls, rectangular blanks having an aspect ratio of 0.75 to 0.1 and direction of one of the diagonals of the blank close to its horizontal position are formed in multi-chamber calibration cylinders; smooth rolls and the final shape of the stock with the specified ratio of stx'an is done by passing wide edges of the stock through the same rolls. Recognized by the invention based on the results of expertise carried out by the State Committee for Inventions and Discoveries of the USSR, Moscow, SU.
