Title: Pretreatment of molten iron
Inventor: AOKI MATSUHIDE
IPC: C21C1/00
Filed: 1986-08-09
Abstract: PURPOSE:To move a stagnating molten iron and to improve the pretreatment efficiency of the molten iron by injecting a flux into the molten iron and applying electromagnetic stirring or gas bubbling stirring to the molten iron stagnating region in the molten iron bath. CONSTITUTION:An injection lace 3 is immersed into the molten iron 2 housed in a ladle 5 and the flux is injected together with a carrier gas such as gaseous N2 into the molten iron. The flux is stirred by the bubbles of the blown gas and is dispersed into the molten iron 2. The pretreatment such as desulfurization of the molten iron 2 by the flux is thus executed. An inert gas such as N2 is blown through a porous plug 6 provided to the bottom of the ladle 5 to stir the molten iron stagnating region 4 formed in the molten iron 2 by the gas bubbling in the above-mentioned pretreatment method. The stagnating molten iron is thereby moved to the reaction interface with the flux and the pretreatment efficiency of the molten iron 2 is improved.

IPC: G01F1/76
Filed: 1981-11-25
Abstract: PURPOSE:To accurately measure the mass flow rate of any kind of gas, by measuring the pressure in a container at a predetermined time interval and successively calculating a mass flow rate. CONSTITUTION:A gas entering through an inlet 36 is controlled by a mass flow controller 30 so as to have a constant flow rate and introduced into a container 31 and then made to flow out from an outlet 37 through a valve 33. In measurement, the valve 33 is closed, and the pressure in the container 31 is successively measured by means of a pressure gauge 32 made of stainless steel at a predetermined time interval (e.g., 0.1sec). Since the volumes of the container 31 and the piping of the measuring circuit are previously set in a memory circuit 38, a mass flow rate is calculated by an arithmetic circuit 34 according to the Boyle-Charles' law and displayed on a display 35. According to this momentary flow rate, the mass flow controller 30 is calibrated and corrected. Upon completion of the measurement, the valve 33 is opened. Thus, the mass flow rate of any kind of gas can be accurately measured.
