Abstract
The utility model relates to a measuring device which is used for measuring hydrogen content in molten metal. One electrode lead wire is arranged on a proton conductor element and is connected to the interior of a ceramic tube. The electrode lead wire connected with the proton conductor element is connected with one pole of a digital voltmeter or potentiometer with high impedance. The other electrode lead wire is arranged in the ceramic tube, and is connected with the other pole of the digital voltmeter with high impedance. A thermocouple is connected with a thermometer. The signals output by the voltmeter and the thermometer are delivered into a computer, and then the computer completes calculation, drawing and printing. The utility model can sensitively reflect the effect on the hydrogen content in aluminium from the factors of furnace turning down, furnace tilting, nitrogen flow variation, slag removal, covering or uncovering of a flow channel, the water content of the nitrogen, regeneration or no regeneration of dewatering agent, temperature, etc.
Description
The utility model relates to a kind of measurement mechanism of measuring Hydrogen in Molten Metals content.
Be used for both at home and abroad now measuring that hydrogen richness is that " loop round-robin method " also claims the TELEGAS method than method in common in the liquid metal, though this method has reliability, but employed device can only be interrupted sampling, and analysis time is longer, can not be to carrying out successional detection before and after the aluminum or aluminum alloy dehydrogenation.And aluminium and aluminium alloy in process of production its dehydrogenation processing procedure be subjected to multiple factor affecting, hydrogen content is different and different with temperature, time, position, the method and apparatus of the survey hydrogen richness of prior art can not adapt to the requirement of continuous fusion-cast.
Goal of the invention of the present utility model is to provide a kind of and can carries out sensing direct, online, continuous, the fast measuring hydrogen richness to metal or metal alloy under the melting state and decide hydrogen production device.
The utility model is realized by following scheme: it is by proton conductor element, connection ceramic pipe, ceramic pipe, contact conductor, digital voltmeter, and thermopair, thermometer, computing machine are formed.It is characterized in that a contact conductor is arranged in proton conductor element and the connection ceramic pipe, the contact conductor that the proton conductor element is connected extremely links to each other with the digital voltmeter of high impedance or potentiometric, another root contact conductor is arranged in the ceramic pipe, and extremely link to each other with another of high impedance digital voltmeter, thermopair links to each other with thermometer, the signal of voltage table and thermometer output is sent into computing machine, is finished by computing machine and calculates and drawing and printing.Wherein the Sensor section of being made up of proton conductor element, contact conductor, digital voltmeter, thermopair and thermometer also can be provided with more than two groups, to satisfy the requirement of continuous fusion-cast.
Through experimental results show that, during hydrogen richness in the utility model chemical sensitisation hydrogen determinator on-line continuous monitoring aluminium, can reflect down delicately that stove, turndown, nitrogen flow change, skim, the covering of chute whether, the regeneration of the water cut of nitrogen, dewatering agent whether, factor such as temperature is to the influence of hydrogen richness in the aluminium.
Accompanying drawing 1 is only passed on a skill from a master to a single disciple the synoptic diagram of induction device for the utility model.
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the chemical sensitisation hydrogen determinator by proton conductor element 6, connect ceramic pipe 5, contact conductor 3, digital voltmeter 2, thermopair 7, thermometer 8, computing machine 1 are formed.A contact conductor 3 is arranged in proton conductor element 6 and the connection ceramic pipe 5, the contact conductor 3 that proton conductor element 6 is connected extremely links to each other with one of the digital voltmeter of high impedance or pot 2, another root contact conductor is arranged at ceramic pipe interior 4, and extremely link to each other with another of high impedance digital voltmeter 2, constitute the hydrogen sensing probe by proton conductor element 6, ceramic pipe 4 and contact conductor 3, thermopair 7 links to each other with thermometer 8, the signal of voltage table 2 and thermometer 8 outputs is sent into computing machine 1, is finished by computing machine and calculates and drawing and printing.Wherein the Sensor section of being made up of proton conductor element 6, contact conductor 3, digital voltmeter 2, thermopair 7 and thermometer 8 also can be provided with more than two groups, to satisfy the requirement of continuous fusion-cast.
During measurement, by figure circuit is connected, insert hydrogen sensing probe and thermopair 7 in the motlten metal simultaneously, voltage table 2 just records two electromotive force between the electrode, thermopair 7 records temperature of melt metal, behind electromotive force value, the temperature value input computing machine 1, show or print the hydrogen richness result by computing machine.
