Title: Method for setting temperature at blowing stop in converter
Inventor: KUWAJIMA SHUJI
IPC: C21C5/30
Filed: 1994-10-20
Abstract: PURPOSE: To improve the prediction accuracy of temp. drop and to enable the economical setting of blowing stop temp. in a converter by reflecting the temp. correction through a ladle history and executing the predicted temp. correction according to the nearest time variation. CONSTITUTION: At the time of setting the blowing stop temp. in the converter, the temp. correction through the ladle history from tapping into the ladle to secondary refining is executed by using the preset continuous correcting curve under condideration of the treatment in each process and the staying time and in addition to the correcting factory by the treatment at the nearest time. By this method, by using the tundish temp. being a final time as the reference, the corrections of continuous casting reaching temp., secondary refining temp., ladle temp., etc., are executed and the blowing stop temp. in the converter can be decided.

Abstract: PURPOSE:To improve the resolution, and to execute a measurement extending from a vacuum ultraviolet area to a far infrared area by deriving a function of a wavelength and a frequency from a Verdet's constant which has converted a function of a variation of a magnetic field intensity by a difference of a Faraday rotational angle. CONSTITUTION:A light to be detected which has passed through a sample S is polarized by a polarizer P1, led to a Faraday rotary element FR to which a magnetic field has been applied by an air-core coil L, in which a polarizing surface of a polarized light is rotated plural times, and from a super-posin signal of optical information in which a Faraday rotational angle differs in accordance with a wavelength, a linearly polarized light component of one direction is detected by an analyzer P2. Also, its signal is converted to an electric signal by photoelectric detectors D1, D2, it is brought to Fourier reverse conversion by a computer CP as a function of a magnetic field intensity, and converted to a signal of a function of a Verdet's constant. The Verdet's constant is in inverse proportion to square of the wavelength, therefore, a signal of a wavelength or a frequency is derived from its signal and a spectral intensity distribution is obtained.
