Abstract: PURPOSE:To enable exact discrimination of the presence or absence of fusion cutting slag of an ingot by subjecting the oscillation which conveying rollers receive during conveyance of the ingot adhered with the fusion cutting slag to a spectral analysis. CONSTITUTION:The oscillation signal detected by an oscillation detector 3 mounted to the bearing of the conveying roller is inputted to a frequency spectral analyzer 11 at the time of conveying the ingot fusion-cut to a suitable length from a steel ingot to the next stage. On the other hand, an ingot position detector 12 is installed just before the oscillation detector 3 to detect the approach of the ingot to the roller mounted with the oscillation detector. The ingot pass signal thereof is inputted to the above-mentioned analyzer 11. The analyzer analyzes the spectral density of the oscillation signal during the passage of the ingot and feeds the spectral density P(phi) to a specific frequency band integrator 13 and a base frequency band integrator 14. An integral value ratio R is computed by an integral value comparing computing element 15 which inputs the ratio together with the threshold value SL to a comparator 16. The ratio is then compared with the SL value and the fusion-cutting slag adhesion signal is outputted as an alarm to a monitor 18.

Title: Determination method of hydrogen sulfide gas by tcd gas chromatograph
Inventor: INABA TOSHIHARU
IPC: G01N27/18
Filed: 1995-05-26
Abstract: PURPOSE: To obtain a determination method in which hydrogen sulfide can be determined precisely without being adbsorbed and saturated even when a pipe is a stainless steel pipe to which the hydrogen sulfide is adsorbed easily by a method wherein a carrier gas with which hydrogen sulfide gas has been mixed is used. CONSTITUTION: When hydrogen sulfide gas is determined by a thermalconductivity- detector(CD) gas chromatograph, a carrier gas with which the hydrogen sulfide gas has been mixed is used, and a pipe or the like is adsorbed and saturated by hydrogen sulfide. Consequently, hydrogen sulfide which is contained in a sample to be measured is not adsorbed to the pipe, and the hydrogen sulfide which is contained in the sample can be determined precisely. As the range of the concentration of the hydrogen sulfide which can be contained in the carrier gas, 0.001 to 0.1mol% is appropriate because of the following reason.  That is to say, the allowable time of a warming-up operation to raise the PCD gas chromatograph needs generally one hour; it is proper that the hydrogen sulfide is saturated and adsorbed to a stainless steel pipe by utilizing the time; and the smaller the usage amount of the hydrogen sulfide, the better because the hydrogen sulfide is a corrosive gas.
