IPC: C21C7/04
Filed: 1980-02-29
Abstract: PURPOSE:To improve the yield of addition of additives by adding the additives by using a cylindrical body immersed diagonally into molten steel in adding the additives to the molten steel in a tundish. CONSTITUTION:In adding additives 11 having high activity of rare earth element such as Ca or Ce to the molten steel 1 in a tundish 2, a specific cylindrical body 3 made of refractories, and a piping 7 for high pressure and a piping 8 for reduced pressure are connected thereto. The leading end of the body 3 is immersed into the molten steel diagonally down to near the bottom of the tundish, thence the internal pressure of the body 3 is increased or decreased by regulating the flow control valves 5, 9 of the piping 7 and the piping 8. At the time when the molten steel 1 is reciprocated in the body 3 by the change in the internal pressure, a feeder 13 is operated to add the additives 11 to the molten steel 1 in the body 3, whereby they are supplied to the deep part of the molten steel 1 in the tundish. An inert gas atmosphere is maintained in the body 3, and since no molten slag 4 exists, the additives are added to the molten steel in high yields without being oxidized and consumed by air and molten slag.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain a derusting method in which rust caused on the surface of a test piece as a steel material or a plated steel material can be removed quickly and precisely by a method wherein the test piece is immersed in a bath composed of an aqueous solution in which hydrochloric acid and hexamethylenetetramine at specific concentrations are contained. SOLUTION: A derusting method is a method in which rust caused on the surface of a test piece as a steel material or a plated steel material is removed in a process in which the rust is quantitatively analyzed. The test piece is immersed in a bath composed of an aqueous solution in which 5 to 25 wt.% of hydrochloric acid and 0.1 to 10 g/l of hexamethylenetetramine are contained and whose solution temperature is within a range of 20 to 70 deg.C. After the rust is dissolved and stripped in this manner, 0.1 to 5 wt.% of hydrogen peroxide is added to the bath. The hydrochloric acid has an action which dissolves iron rust, and the hexamethylenetetramine has an action which increases the removing property, especially the stripping property, of the rust. The hydrogen peroxide has an action which dissolves the rust which is stripped so as to be deposited inside a container.  Thereby, the rust on the surface of the test piece can be removed completely in a short time while the erosion of substrate iron is being suppressed.

Title: Monitoring of nuclear power plant
Inventor: ENOMOTO MITSUHIRO
IPC: G21C17/00
Filed: 1989-02-06
Abstract: PURPOSE:To prevent frequent occurrence of abnormality determination by a method wherein, when a threshold value is once exceeded, the frequency of the threshold value being exceeded is monitored to use the frequency as an information for setting another threshold value and the threshold value for monitoring an abnormal phenomenon is updated temporarily in an automatic manner. CONSTITUTION:In a data processing element 2, an average value is determined from data inputted from a data input element 1, by using a prescribed formula. A comparing-determining element 3 compares a difference between the average value determined by the processing element 2 and an instantaneous value with a threshold value and determines the same. A storing element 4 stores time-series data before and behind an abnormality when it is detected in the determining element 3. An output element 5 outputs the time-series data stored by the storing element 4, the time-series data counted in the determining element 3 and the number of times of the determined threshold value before updating being exceeded, which is counted in the determining element 3. According to this constitution, the frequent occurrence of abnormality determination and the lowering of detection sensitivity due to excessive raising of the threshold value can be prevented by updating the threshold value automatically, while an optimum threshold value can be set on the basis of the number of times of the threshold value before alteration being exceeded.
