Title: Desulfurization and dephosphorization of molten pig iron
Inventor: SATOU SHIYUNJI
IPC: C21C1/02
Filed: 1979-06-30
Abstract: PURPOSE:To raise both desulfurization and dephosphorization efficiencies as well as to make the discharge of slag easier by a procedure in which a slag-softening agent is added to molten pig iron after being taken out of furnace and then a desulfurizing agent and/or a dephosphorizing agent is added with stirring. CONSTITUTION:A slag-softening agent, e.g., soda ash, fluirite, a boronic compound, etc., together with a carrier gas, is blown into the molten pig iron 3 in the mixer car 2 from the lance 1 to lower the coagulating temperature and viscosity of the slag 4 for softening. Then, a desulfurizing agent and/or a dephosphorizing agent is injected, together with a carrier gas, into the molten pig iron 3 from the lance 1, where the wettability of the slag 4 and the molten pig iron 3 is made better because of the fluidity of the slag 4 and therefore the desulfurizing and/or dephosphorizing reaction in the molten pig iron 3 is rapidly accelerated. Thus, the desulfurizing agent, etc., used can be contributed to the desulfurizing and/or dephosphorizing reaction without wasteful consumption substantially.

Title: Remote water level sensing device
Inventor: YOKOAJIRO YOSHIYUKI
IPC: F24H1/00
Filed: 1987-04-03
Abstract: PURPOSE:To provide a highly accurate water level sensing device by computing the water level in the water level computing section from the difference between the signal from a pressure sensor and the stored reference value by detecting that portion of pressure which has leveled after the hot water delivery was started, said pressure being stored in the reference pressure memory section, and detecting the pressure build-up thereafter. CONSTITUTION:Upon reception of command for starting hot water delivery through a control button, a three-way valve 13 is switched to the (b) side by a water level control section 22 to start the hot water delivery to a bath tub 11 through a hot water supply passage 14, a pump 15 and a supply pipe 16, and one end of a return pipe 12 si closed at the same time by the three-way valve 13. While the water level remains in the (c) range after the start of hot water delivery, the signal from a pressure sensor 17 maintains a constant level as shown by (d), and the leveling sensing section detects a lack of change in pressure over a certain time interval (t) and transmits it to the reference pressure memory section. When the water level enters the (e) range thereafter, the signal from a pressure sensor 17 increase with the increase of the water level, and the pressure build-up sensing section picks up the rising water level at the moment (g). The water level computation section 21 determines the difference between the signal from the pressure sensor 17 and the stored value in the reference value memory section 20, and the water level signal is transmitted to the water level section. Therefore, the water level in the bath tub can be accurately detected.
