Title: Method for straightening bent roll
Inventor: ADACHI YUJI
IPC: B21D3/00
Filed: 1993-12-30
Abstract: PURPOSE:To straighten bent of a roll in on-line in a short time when a method is used when a steel plate is rolled or a billet is drawn. CONSTITUTION:A groove 2 is formed by gauzing a projecting side of the roll 1 in which a bent is generated by thermal stress. When the groove 2 is build-up welded, the welded part is applied with shrinking force and the bent is straightened and the original shape is recovered. For instance, 18.5kg build-up welding is executed for 1.2mm bent of a roll. Then, the surface of welded part is finished and working is continued without exchanging the roll. Accordingly, the bent of roll is straightened without exchanging roll in on-line in a short time.

Abstract: PROBLEM TO BE SOLVED: To shorten the calculating time of the refractive index and thickness of a thin film by measuring the phase slippage and displacement of main axis defined by specific expressions, which are parameters of the elliptically polarized light reflected from a sample surface, and adapting multiple regression analysis. SOLUTION: The phase slippage Δ and main axis displacement Ψdefined by formulae I, II, which are parameters of the elliptically polarized light reflected from a sample surface subjected to a thin film measurement, and the thickness and refractive index of the thin film are determined from the respectively corresponding measured values. Namely, the thickness and refractive index are approximated as the function of the phase slippage Δ and main axis displacement Ψ, and the thickness of the refractive index of the thin film are determined by use of this function. This function is determined by multiple regression analysis having the measured structural parameter on a reference sample as an objective variable and the ellipso-parameters Δi, Ψi determined with respect to the reference sample (i=1-n/2) as illustrating variables. According to this, the calculation for determining the refractive index and thickness of the thin film is ended once, the calculating time is shortened, and an ellipsometry with short measuring time can be performed.
