Description
Technical Field
The invention relates to the technical field of molten iron slag layer thickness measurement, in particular to a convenient and efficient molten iron slag layer thickness measurement system.
Background
The slag amount (i.e. the slag proportion) of molten iron for steel making in a blast furnace has different regulations for large steel plants in China, but in daily production, the slag amount measurement of molten iron is time-consuming, the test is unchanged, and the risk coefficient of manual detection is high. At present, when the slag amount of molten iron for steel making of a blast furnace is large, a slag skimming mode is often adopted to weigh the slag of the molten iron by a scale, the slag skimming operation is time-consuming, low in efficiency and labor-consuming, production of a steel mill and an iron mill is not facilitated, a certain risk exists, whether the slag amount meets the production requirements of a company is difficult to determine in real time, and difficulties are brought to quantitative analysis of the slag amount of the molten iron of the blast furnace to guide actual production of the iron making and reasonable slag deduction during molten iron settlement. And a tracer (BaCO is used 3 ) Due to BaCO 3 The price is high, the calibration cost is high, and after molten iron is added, part of slag can be generated, so that the slag quantity is increased;
the invention is characterized by comprising the following steps: a simple tool for rapidly detecting the slag amount of molten iron (application number: 2013200071828.7, application date: 2013.02.08), which comprises an oxygen blowing pipe, a handle and a trapezoidal aluminum strip; the tool is provided with an oxygen lance, and the tail end of the tool is provided with a handle; a stepped aluminum strip is arranged in cooperation with the oxygen lance, and one end of the stepped aluminum strip is inserted into the end part of the oxygen lance.
Although the patent has the advantages that the thickness of the slag quantity of the molten iron can be rapidly measured, and the slag control condition of the slag of the blast furnace can be objectively reflected; but it is disadvantageous in that: (1) The thickness of the molten iron slag layer is measured by adopting a slag measuring tool manufactured by an aluminum rod, and the loss of aluminum is large because the oxygen blowing pipe is self-consuming; (2) The invention needs an operator to hold the handle at the tail end of the oxygen lance, and the equipment is inserted below the liquid level of molten iron for measurement, so that the automation and informatization degree are low, and the automatic dynamic data acquisition and analysis cannot be realized; (3) The measuring labor intensity of operators is high, and the manual participation degree is high.
A method for measuring the slag quantity of blast furnace includes such steps as weighing the molten iron in molten iron tank, loading it in converter, weighing the molten iron in molten iron tank, pouring out the slag, breaking, grinding, magnetic separation and sieving to obtain the product, weighing the product, detecting the mass fraction of Fe and C, and calculating the total mass fraction of slag.
Although the method has the advantages that the slag quantity of the molten iron can be measured more accurately; but it is disadvantageous in that: (1) The complex measurement method can lead to prolonged processing time or higher computational power requirement and is prone to data errors in the measurement process for large-scale data; (2) The real-time property of the measured data is insufficient, the measuring time is too long, and the lack of real-time data can lead to delayed feedback, so that actions cannot be timely taken or decisions cannot be made. The production cannot be guided well; (3) This approach requires more resources and investment, including technical equipment, labor costs, training, and the like. Resulting in an increase in production cost.

firstly, an electric push rod 17, a servo motor 20, a thermal imaging camera 21 and a micro motor 30 are respectively connected with an electric box of a control device 3 through leads, a high-temperature-resistant ceramic electric conduction rod 11 is electrically connected with the control device 3 through a high-temperature-resistant electric wire 15, the device is fixedly installed, an operator uses the control device 3 and a potential difference display to operate the device and set an initial speed, and then the servo motor 20 is started to drive a winding roller 6 to perform preliminary unwinding operation on a lifting rope 16, so that the high-temperature-resistant ceramic shell 9 attached to an anti-swing rod 19 is primarily lowered, and is not attached to the anti-swing rod 19;
secondly, the micro motor 30 is started to drive the screw 31 to rotate, and the lifting adjustment of the lifting column 13 is conveniently realized by driving the screw 31 to rotate forwards and backwards, so that the height and horizontal position adjustment operation of the supporting roller 14 on the bending and sagging position of the steel wire rope can be realized, the farthest distance can be adjusted according to the outward movement of the supporting roller 14, the outer side of the lifting rope 16 sagging from the supporting roller 14 is conveniently abutted against the anti-sway bar 19, the lifting rope is in a folded line shape, the stability and the anti-sway effect of the follow-up lifting rope 16 during continuous unreeling are conveniently improved, and the stability of the high-temperature-resistant ceramic shell 9 and the high-temperature-resistant ceramic conductive rod 11 during descending can be further improved; meanwhile, according to different adjustment distances of the support rollers 14, the downward inserting detection position of the high-temperature-resistant ceramic conductive rod 11 can be changed, so that the application range of the device and the convenience in use are effectively improved;
