Description

(54) THE METHOD FOR DETERMINING THE TECHNOLOGICAL PARAMETERS OF DOMAIN FLOATING The displacement current is proportional to the displacement, which is indicated by the recorder as an increase in the ordinate of the recorded parameter. To bind the detected current to the amount of movement of the research probe, a movement sensor 2 is installed on the machine (for example, a rheochord type), the signal of which is output to a recording device 6, which operates in parallel with the current one. The magnitude of the resistivity force of the probe, characterizing the tightness of materials in any place along the path of the probe from the wall of the shaft to the furnace axis, can be determined from. formula. .-: -4СГА, (3-3, .0, LGI Zn, where J is the current value of the current, and; is the value of the amperage current of the probe (before meeting with schichtite), and; Mrf is the nominal moment developed motor (according to the passport), kGm; C is the coefficient determining the relationship between the nominal force of the PH developed by the probe and the nominal torque MH on the shaft at the water engine C /. „. AN / UN is the nominal current of the drive motor (the current at which the motor develops nominal moment Mc) D is the diameter of the research tube (probe), m. P p and m. Sounding is performed by a typical machine. gas sampling and temperature measurement with a probe of 10400 mm. To register a change in the density of charge materials in the furnace working space, a shunt is installed in the circuit of one of the stator windings of an induction motor with a short-circuiting probe drive rotor. oscilloscope cable. The oscillogram records a voltage of 50 Hz, proportional to the current in the stator winding of the motor (1). The EASTER movement (2) of the research probe is carried out with the aid of a circular reichord fed by

-715,626 tons of battery, while the reohord is pressed against the output shaft of the low-speed drive rector stage. Conducting probing using the proposed method allows one to expand the range of studies of the blast smelting process, makes it possible to determine the location of the charge layers along the radius, as well as the quality of the radial distribution of the material, changing the location of the layers at different levels. The method of determining the technological parameters of the blast furnace smelting, including the insertion of the probe along the furnace radius, the registration of parameters, characterized in that, in order to determine the resistivity of the charge materials along the radius, the resistivity of the charge is determined by the change of the current. according to the formula 4SMn (.;). where J is the current value of POWER of current, and is the magnitude of the no-load current of the probe (before the meeting, with the charge), a; MH is the nominal moment developed by the engine (according to the passport), kGm; С is the coefficient that determines the relationship between the nominal force of the PH developed by the probe and the nominal moment MH on the shaft of the drive engine. . v / .r is the rated current of the drive motor (the current at which the motor develops the rated torque), and; diameter of the research tube (probe), m.
