Embodiment Construction

[0015] see image 3 , Figure 4 A torpedo tank car molten iron liquid level detection device, in which a tank reference plane is made on the upper surface of the molten iron tank body of the tank car, so that the height distance from the tank reference plane made by each molten iron tank to the bottom of the tank is consistent. A casing and an electric motor are housed above the blast furnace taphole torpedo tank car, and a moving track 21, a screw screw mandrel 34, a screw thread sleeve 33, a moving platform 24, and a sensor 4 are housed in the casing. The moving track 21 and the screw rod 34 are installed on the side plate 28 of the box body and are installed in parallel. The side plate 28 of the box body is installed on the bottom plate 27 of the box body. The bottom plate 27 is located at the bottom of the box body and can be used to fix the box body on the installation base On, the box body top is covered with cover plate 22. The mobile platform 24 is installed on the m...

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 [0001] The invention relates to a method and a detection device for detecting the liquid level of molten iron in a torpedo tank car when a metallurgical blast furnace taphole is filled with molten iron. (2) Background technology [0002] The existing method of measuring the molten iron level of blast furnace torpedo tank car filling is a fixed-point measurement method with a fixed reference, that is, the installation point of the liquid level gauge sensor is used as the measurement reference point, and the tank car track surface is used as a reference reference for fixed-point measurement. The calculation method of the liquid level is: the height from the sensor to the track surface of the tank car minus the height from the track surface to the bottom of the molten iron tank, and then subtracting the height measured by the sensor from the sensor to the liquid level of the molten iron in the tank to obtain the actual height of the molten iron, see figure 1...
