Abstract
An electrode moving method for automatically measuring the slags thickness over molten metal level is composed of probe, lifting rod, varistor, power supply, light source, photoelectric code disk, photoelectric device, amplifier-shaper circuit, calculator, A/D converter and computer. During the electrode descending, the descended distance of lifting rod when electrode loop is closed is used as surface position of slags. The descended distance of lifting rod when output of electrode loop steps down again is the interface between slags and molten metal. Their difference is just the thickness of slags.
Description
The present invention relates to a kind of Auto-Test System of measuring high-temperature metal liquid level and slag layer thickness, it not only can measure slag liquid level, metal liquid level, and can measure the slag layer thickness on the molten metal top layer simultaneously.This system can be applied to slag in the torpedo hot metal mixer car/molten iron system, slag in ladle, tundish, the continuous cast mold/molten steel system, and the slag of other occasion/molten iron system, slag/molten steel system, slag/copper water system, the metal liquid level of slag/aluminium water system and the automatic measurement of slag layer thickness.
At present, the technology that is used to measure metal liquid level and slag liquid level has multiple.There is radioactive control problem in the gamma-rays method, there is the shortcoming that installation bothers, precision is not high in thermocouple method, there is the deficiency that measurement range is little, need take cooling provision to coil in eddy-current method, laser, infrared, microwave method and industrial television can only be measured the surface location of molten metal or slag again, energy measurement thickness of slag layer not, and generally electrode is immersed the environment that electrode rule in the liquid is difficult to directly apply to high-temperature slag and molten metal, perhaps will increase the cost of measurement greatly, and also be not used in the measurement slag layer thickness.
The purpose of this invention is to provide a kind of Auto-Test System of measuring high-temperature metal liquid level and slag layer thickness.The object of the present invention is achieved like this: the metal liquid level slag thickness probe that the high temperature electrode of two disconnections is made, be loaded on the lifting measuring staff, the output voltage at electrode two ends will change with the variation of lifting measuring staff dropping distance, thereby measures the deep and metal liquid level of molten slag layer.
Concrete enforcement of the present invention is provided by following examples and accompanying drawing thereof.
Fig. 1 is the enforcement block scheme of the automatic test for metal liquid level slag thickness by moving electrode method of proposition according to the present invention.
Describe performance of the present invention in detail below in conjunction with Fig. 1.
The present invention is made up of metal liquid level slag thickness probe 1, lifting measuring staff 2, electrode loop, opto-electronic testing apparatus and computer system.
The metal liquid level slag thickness probe 1 that can change is installed on motor slows down the lifting measuring staff 2 that moves up and down in the socket joint mode, electrode loop is made up of two disconnection electrodes, rheostat 10, power supplys 11, and opto-electronic testing apparatus is made up of light source 3, photoelectric code disk 4, photoelectric device 5, amplification and rectification circuit 6 sum counters 7.Computer system is made up of A/D converter 9, computing machine 8, printer.
The output voltage at the electrode two ends in the metal liquid level slag thickness probe 1 is a constant value from dropping to contact slag surface before, when electrode contact slag surface, owing to form a closed-loop path, step will take place suddenly and descend in output voltage, electrode drops to before contact slag/molten metal interface, output voltage will continue to descend, owing to exist between slag resistivity and the molten metal resistivity than big difference, when electrode contact slag/molten metal interface, output voltage will have a step to descend again, and output voltage is imported computing machine 8 behind A/D converter 9.On the other hand, measure the dropping distance of lifting measuring staff 2 by photoelectric test system, lifting measuring staff 2 dropping distances that photoelectric test system obtained are imported computing machine 8 behind counter 7, the distance that lifting measuring staff 2 descends during with the electrode loop closure is as the position on slag surface, the distance that lifting measuring staff 2 descends when occurring step decline for the second time with the electrode loop output voltage is as the position at slag/molten metal interface, the difference of these two distances is a slag layer thickness, computing machine 8 just can show or print the slag liquid level with after the data processing, slag layer thickness, the metal bath surface position.
If there is not slag on the metal bath surface, the position on the distance metal corrugated that measuring staff descended when then electrode loop was closed.
To from the slag/molten iron system of blast furnace with from the slag/molten steel system of converter, two distance between electrodes are 10～50 millimeters, supply voltage is set at 10～30 volts, when the resistance of rheostat 10 is set at 10～100 ohm, can obtain more satisfactory test result.
