Abstract

The utility model is composed of a steel cap 1, a pressing washer 2, a fixed sleeve 3, an electrode 4, a copper conductor 5, an outer layer of paper tube 6, an inner layer of paper tube 7, a plastic pipe 8 and insulated powder 9. A melted metal level slag testing probe is arranged on a lifting testing bar through a manner of socket joints. The specific resistances of air, slag and melted metal have greater differences, so that the position of a slag surface, the position of an interface between the slag and the melted metal, and the thickness of a slag layer can be obtained through characteristic signals by descending the electrode in the probe to be contacted with a testing system on the slag surface and the interface between the slag and the melted metal.

Description

The metal liquid level slag thickness test probe

The utility model relates to a kind of probe of measuring high-temperature metal liquid level and molten slag layer thickness.

At present, the probe that is used to measure the high-temperature metal liquid level has multiple, but the probe that is used to measure the molten slag layer thickness does not also have.Normally electrode is immersed in the testing liquid with electrode method measuring liquid level, variation by liquid-immersed electrode height causes that resistance variations tests the liquid level height, perhaps electroplax is fixed in certain position, relies on the conducting of electrode whether liquid level to be done fixed test or warning.But the former exists electrode life short, and also is unsuitable for testing the high-temperature metal liquid level, and the latter then can only measure the position on molten metal or slag surface, not energy measurement slag layer thickness.

The purpose of this utility model provides a kind of both energy measurement high-temperature liquid metal positions that is used for, and can test the probe of molten slag layer thickness again.

The utility model is achieved in that the front end of probe has the steel cap of side perforate all around, and it places between behaviour's pretective sleeve pipe and the packing ring.Two electrodes are arranged in the steel cap, draw in insulating packing by lead respectively.Rely on the decline of lifting measuring staff during test, probe is immersed in slag or the molten metal; After test finished, the lifting measuring staff rose, and will popping one's head in, it is unsettled to promote.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structural profile synoptic diagram according to the metal liquid level slag thickness test probe that the utility model proposes.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing 1.

The utility model is made of steel cap 1, pressure pad circle 2, fixed muffle 3, electrode 4, copper conductor 5, outer paper tube 6, internal layer paper tube 7, plastic tube 8 and insulating powder 9.The steel cap 1 of perforate is lived by pressure pad circle 2 and fixed muffle 3 solid pressures around the side of probe front end; Medial surface with fixed muffle 3 on pressure pad circle 2 has outer paper tube 6, and fixed muffle 3 tightly is placed on the outer paper tube 6; Insulating powder 9 has been filled up in the interior space of outer paper tube 6; Have 4, two electrodes 4 of two electrodes to enter in the insulating powder 9 in the steel cap 1, and draw copper conductor 5 by welding on electroplax 4 tops by pressure pad circle 2; There is internal layer paper tube 7 inboard, top at outer paper tube 6; Except that insulating powder 9 is arranged, also has plastic tube 8 in the interior space of internal layer paper tube 7; Copper conductor 5 is drawn by two places up and down of plastic tube 8.The metal liquid level slag thickness test probe is installed on the lifting measuring staff by the socket joint mode, relies on the decline of lifting measuring staff during test, and probe is immersed in slag or the molten metal.Because the resistivity of air, slag, molten metal exists than big-difference, by obtaining the characteristic signal that electrode in the probe drops to the test macro at contact slag surface, slag molten metal interface, can measure slag surface location, slag molten metal interface location and slag layer thickness.
