Title: Method for desulfurizing reduced iron and apparatus therefor
Inventor: MATSUMURA TOSHIHIDE
IPC: C21B13/00
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To cost-effectively enhance the quality of reduced iron by acting gaseous hydrogen on high-temp. reduced iron pellets right after reduction and efficiently desulfurizing these pellets. SOLUTION: The reduced iron pellets right after reduction in the high-temp. state of 1000 to 1200 deg.C are charged into a desulfurization reactor. A non-oxidative gas contg. gaseous hydrogen or hydrogen source at >=30wt.% in terms of hydrogen quantity is fed as a desulfurizing gas into the reactor, by which the reduced iron is desulfurized. The desulfurizing gas is fed into the reactor after the gas is preheated to 590 deg.C by a gas heater 5 in such a manner that the gas attains the temp. 800 deg.C necessary for briquetting the reduced iron pellets in the reactor 1. The sulfur content of the reduced iron is made into <=0.05% by such desulfurization treatment. The waste gases contg. the steam and hydrogen sulfide from the desulfurization reactor 1 is as high in temp. as about 800 deg.C and, therefore, these waste gases are introduced into a heat exchanger 2 and are used for preheating the desulfurizing gas to be fed into the reactor 1. The moisture and the sulfur compd. are thereafter separated and removed from the gases by a gas cooler 3 and an H2 S removing device 4 and are returned together with a replenishing gas to the reactor 1.

As a result, the resin magnet on which the surface magnetic field is improved by about 5-30% can be obtained.

Filed: 1992-11-10
Abstract: PURPOSE:To respectively diagnose an electron beam and an electron beam mirror cylinder by judging the states of both of them on the basis of the average value of the difference between the indication position and electron beam irradiation position on a screen and the magnitude of the irregularity thereof. CONSTITUTION:When measurement is started, a control device 12 allows an electron beam to scan a sample 10 in a planar state to obtain the image of the sample. Measuring wiring is indicated on this image and secondary electron signal quantity obtained by scanning the sample by an electron beam so as to cross the wiring at a right angle is plotted to obtain a wiring profile. After the shift quantity DELTAX of the indication position and the actual irradiation position of an electron beam is stored in the memory part of the device 12, a waveform is measured to measure wiring potential. After the completion of measurement, the average value of the difference between both positions and the irregurality sigma thereof are calculated from the stored shift quantity DELTAX and the state of an electron beam or an electron beam mirror cylinder 13 is judged from the calculated results. By this constitution, it can be discriminated whether the shift of the electron beam irradiation position can be restored by correction or is caused by the non-stability of an electron beam and the electron beam or the mirror cylinder 13 can be diagnosed.
