METHOD OF DETECTING ROLL CLEARANCE SETTING ERROR FOR UNIVERSAL ROLLING MACHINES AND METHOD OF ROLLING H-BEAM HAVING FAVORABLE FLANGE SIZE BY UTILIZING SAID METHOD |
摘要 |
A method of finishing a shaped steel having an H-shaped cross section from a roughly shaped steel piece having webs and flanges, which has been subjected to breakdown rolling, by passing the piece through a shape-steel rolling equipment array consisting of a combination of a universal rough rolling machine and a universal finishing rolling machine, characterized in that the thicknesses of four portions, i.e. the upper, lower, left and right portions of a flange of the rough shaped steel piece are measured with hot size measuring instruments located in proximity to the universal rough rolling machine, a deviation between the axies of the upper and lower horizontal rolls in the universal rough rolling machine, a deviation between the degrees of opening of the left and right vertical rolls therein and a deviation between the central position in a clearance between the upper and lower horizontal rolls and that between the vertical roll bodies being determined on the basis of the results of the measurement mentioned above. |
