Description
Technical Field
The invention relates to a rapid determination device for the temperature of a smelting furnace of a vanadium-titanium ore blast furnace, and belongs to the technical field of iron making.
Background
In the blast furnace smelting process, a heat system mainly represented by the furnace temperature is one of four operation systems of the blast furnace, and the proper furnace temperature and stable furnace temperature are the bases for realizing active and stable operation of a blast furnace hearth and the bases for stable and smooth operation and efficient smelting of the blast furnace. For the blast furnace smelting of vanadium titano-magnetite, especially for the blast furnace smelting of high titanium type vanadium titano-magnetite, the content of generated slag TiO2 is higher than 20%, the flow property and the separation effect of slag iron in a hearth are greatly influenced by the furnace temperature, on one hand, too high furnace temperature can cause excessive high-melting-point Ti (C, N) generated by the over-reduction of the slag TiO2, so that the slag iron is sticky and difficult to separate; on the other hand, when the melting temperature of the high titanium type blast furnace slag is as high as 1380-1420 ℃, the temperature of the slag iron in the hearth is close to the melting temperature of the slag, the viscosity of the slag is increased sharply, and the slag iron becomes viscous and difficult to separate. Therefore, in the process of controlling the blast furnace, the vanadium titano-magnetite blast furnace smelting operator aims to achieve physical heat and chemical cooling, namely, the slag iron has abundant furnace temperature, and the Si and Ti content in the molten iron is reduced as much as possible.
In order to realize the purpose of proper furnace temperature control in the blast furnace smelting of vanadium titano-magnetite and the purpose of physical heat and chemical cool of slag iron, iron-making production staff try a lot of efforts. In the aspect of molten iron chemical temperature, if the frequency of molten iron sampling and chemical detection is increased, the analysis of molten iron components is performed once per tapping, so that blast furnace operators can master the change of furnace temperature. However, in practice, the chemical inspection frequency still cannot meet the requirement of blast furnace operators on judging the furnace conditions, firstly, the primary tapping process time is as long as 40-120 min, the furnace temperature can be changed to heat or cool in the initial stage, the middle stage and the later stage of tapping, and the primary chemical component detection of primary tapping is obviously difficult to accurately judge the change trend of the furnace temperature. Secondly, the existence of thermal hysteresis effect of the furnace temperature is judged by using the chemical detection of molten iron Si or Si+Ti, the time for sampling, sample feeding and chemical component inspection is long, and when the chemical detection result is out, the furnace condition of the blast furnace has changed greatly, and the furnace condition is regulated according to the detection result. In the aspect of detecting the physical temperature of molten iron, the physical temperature of the molten iron is fed back in time by carrying out one-time plug-in thermocouple temperature detection on each tapping, but the thermocouple belongs to a disposable consumable, and has high frequency and high detection cost; the frequency is low, and the trend that the change of the furnace temperature cannot be effectively and accurately fed back is also presented; meanwhile, the time for measuring the temperature, the depth of the thermocouple inserted into the molten iron and the size of the tapping iron flow all influence the physical temperature measurement, so that the correlation between the physical temperature detection and the change of the hearth thermal state represented by the actual furnace condition is poor. The infrared online continuous temperature measuring device for the molten iron is popularized in the field of iron making in recent years, and the furnace temperature measuring frequency is improved and the molten iron temperature measuring cost is reduced by continuously measuring the surface temperature of the molten iron. However, in the process of smelting iron out of a vanadium titano-magnetite blast furnace, the problems of large smoke dust and serious slag iron splashing in the iron out process exist, the infrared temperature measurement is easily affected by high-temperature smoke dust, and the temperature of slag iron at a tap hole cannot be accurately measured; even if the temperature measuring point is adjusted to a small well or an iron runner at the tail end of the tapping main runner, the accuracy of the infrared continuous temperature measurement result can be affected due to the reasons that the temperature is reduced in the tapping process, tiC and other substances are separated out and the upper layer of the iron runner is covered by a separated slag-iron mixture, or due to the large slag quantity, the skimming of a skimming device is not clean, the scum floats on the surface of molten iron and the like. Therefore, more time is taken by blast furnace operators, the blast furnace is properly operated and regulated according to the rough estimation and judgment of the furnace temperature by observing the brightness degree of iron slag and taking slag to observe the color of slag in the tapping process and relying on long-term accumulated experience. However, such a judgment method depends heavily on the judgment experience of the operator, and is affected by the weather and time during sampling, and the influence of light during observation of the sample is large in judgment error of the color. Therefore, in the smelting process of the high-titanium vanadium titano-magnetite blast furnace, the stability control of the furnace temperature is still poor, the fluctuation of the furnace temperature is still large, and the production accident caused by incorrect adjustment or untimely adjustment due to inaccurate judgment of the furnace temperature occurs, so that huge economic loss is brought to the blast furnace production. Therefore, the method is suitable for the characteristics of the vanadium titano-magnetite blast furnace smelting, can be used for rapidly judging the furnace temperature at high frequency with low cost and relatively accurate, and is very important for helping blast furnace operators to stabilize the vanadium titano-magnetite blast furnace smelting.
