Description

one

The present invention relates to ferrous metallurgy, in particular, to devices for the automatic control of open-hearth smelting.

A device is known for monitoring the decarburization of a steel-smelting bath, containing P1, its fuel consumption and carbon dioxide concentration sensors, which are synthesized in exhaust smoke, subtracting biii kii (pchmrator, and instruments), which are percipient, which is given to them by ycTiipylOHuie, which is compressed by this component, which is obtained by ycTiipylOHuie. south of the rate of burnout of chlorine from the bath.

The known device determines the decarburization rate of the metal with a low accuracy of complete or partial neglect of the dynamics of the process of formation and transfer of formation and formation into the computing device. So, if information on the CO-2 content in a burnt-out fuel arrives in the calculator 1st device almost instantly, then similar information from gas analysis devices arrives with a time delay reaching 40 seconds or more. This delay is determined by the speed of the convective-diffusion process and the mass transfer of the waste combustion products in the area of the working area of the furnace - the place where smoke is sampled. To this delay is added a delay in the pelvic analysis equipment. As a result

Signals asynchronous in time are sent to the inputs of the computing device, which leads to an error in the output signal of the device. These diaamic errors accumulate the more, the longer the melting and the more technological disturbances occur during its course.

IT1) K) of the invention is an improvement in the accuracy of controlling the decarburization of the metal.

For this, the proposed device is equipped with an electric model of the chimney tract, the entrance of which is connected through an integrator with fuel consumption and concentration of carbon monoxide in the exhaust smoke, and the output with a subtraction unit.

The block exema of the device described is given in the drawing.

The device contains sensors of natural gas flow meters 1 i of fuel oil 2, opto-acoustic gas analyzer 3, ferrodynamic converter 4, compensating self-recording ferrodynamic device 5, second gas generator-samopii uiip bridge, 7 output signal converter, electric chimney model 11) of the act - dipamic compensator 8, subtractive device 9, automatic)) single point self-decaying 10 and electronic car 11 potentiometers, groups and pre (; b;) a: ;; iKiie.ii. 12, ca: -: vii ;; i: iivi; inii,; п11иа; op; i:;: i; niiierpaiOjj-cv rMai)) K; and not iOMiiin .: ii r: aliii: -: I i. 1sl () dia /; ;;;: f :) rma; l; | o iipijueccc iyozug / l: 5 liociyuaei roshzans on the routes of sisyul s: from the camp 1 si 2 p o optoacoustic ha:; oa, alp. and: ora 3. ai: a; in;; ip ioinei; ) aa ss- about smoke li boar.
