Abstract
The invention relates to a kind of molten iron liquid level detecting method and of the blast furnace torpedo tank car and the device. On the upper surface of the molten iron container of the tank car creates a tank base surface. On the blast furnace taphole of the torpedo tank car installs a distance measuring sensor which can move on the base orbit. It is controlled by the controller, the sensor moves between the upper locations of the molten iron tank mouth and the tank base surface. It can measure the distance between the sensor and the tank base surface and the distance between the sensor and the molten iron liquid level. The calculating method of the molten iron liquid level in the tank is as follows. The height between the sensor and the tank base surface adds the height between the tank base surface and the tank bottom, detracts the height between the sensor and the molten iron liquid level in the tank and obtains the real height of the molten iron liquid level. The detecting method of the invention is exact; the detecting device is simple; the operation is convenient.
Description
(1) technical field
The present invention relates to the metallurgy high furnace tapping hole when torpedo tank car can molten iron, be used for the detection method and the pick-up unit of molten iron liquid level in the hot-metal ladle and carriage.
(2) background technology
The metering system of existing blast furnace torpedo tank car can molten iron liquid level is, the one-point measurement mode of fixed reference, that is: and the mounting points with the liquid level flowmeter sensor is a datum mark, is basis of reference with the tank car raceway surface, carries out one-point measurement.The computing method of liquid level are: sensor deducts the height of raceway surface to the hot-metal bottle bottom to the height of tank car raceway surface, deduct again sensor that sensor records to jar in the height of molten iron liquid level, obtain the true altitude of molten iron, referring to Fig. 1.
This kind metering system is a kind of Utopian metering system, guarantee that the accuracy of measurement result is difficult to accomplish.Because this Utopian metering system is based upon: 1. each tank car height of hypothesis is consistent, if inconsistent, process can not change after measuring and depositing archives in more at least.2. sensor is constant to the relative distance of tank car raceway surface.3. there is not other factors can cause the variation of sensor to relative height between hot-metal bottle bottom or jar mouth.Under the prerequisite that these several promises have been arranged, just can realize measuring comparatively accurately by computed in software.But above-mentioned these factors often change under actual operating position.Torpedo tank car mainly is made up of following locomotive part and the hot-metal bottle two parts that are installed on the locomotive, hot-metal bottle bearing support and tilting equipment etc. are housed between locomotive and hot-metal bottle, torpedo tank car often needs maintenance, because the process of parts manufacturing and maintenance inevitably can cause the high and low difference of hot-metal bottle, and this error is along with the irregular variation of maintenance meeting of tank car, irregular seeking.Blast furnace has a plurality of tapping holes, even the torpedo tank car rail level benchmark under the tapping hole is consistent when design or construction, in actual use under hundreds of tons the weight, for a long time also can change because of land subsidence time, and this changes along with use also can constantly change also irregular seeking.And because high and low error etc. after the inconsistent heavy burden that produces of characteristic of locomotive shock-proof spring.These factors all can have a strong impact on the accuracy of molten iron level gauging, so that finally cause the deviation of measurement result, sometimes or even serious deviation, even frequent demarcating and revising also is difficult to make its measurement result to keep accurately.
(3) summary of the invention
The object of the present invention is to provide a kind of torpedo tank car molten iron liquid surface measuring method and device, this detection method and device, solved the inaccurate problem of the measuring basis change measurement result that causes of blast furnace torpedo tank car molten iron filling liquid level, pick-up unit is simple in structure, and is easy to operate.
The present invention is achieved in that a kind of torpedo tank car molten iron liquid surface measuring method, it is characterized in that making a tank body reference field at the molten iron tank body upper surface of tank car, a distance measurement sensor that can move on benchmark track is housed above the blast furnace iron notch torpedo tank car, and sensor is moving between hot-metal bottle mouth top position and tank body reference field top position under the control of controller; When sensor moved to tank body reference field top position, what sensor recorded was the distance of sensor to the tank body reference field; When sensor moved to hot-metal bottle mouth top position, what sensor recorded was that sensor arrives jar distance of interior molten iron liquid level; The computing method of molten iron liquid level are in jar: the sensor that records with sensor adds the height of upper tank body reference field bottom the hot-metal bottle to the height of tank body reference field, deduct again sensor that sensor records to jar in the height of molten iron liquid level, obtain the true altitude of molten iron liquid level.
Above-mentioned torpedo tank car molten iron liquid surface measuring method, the tank body reference field of described each hot-metal bottle made all is consistent to the height distance at jar end.
