Description
Technical field
The utility model belongs to the ferrous metallurgy category, relates in particular to a kind ofly to can be used for carrying out and control blast furnace ironmaking process with the work safety that guarantees blast furnace and a kind of diagnosis blast furnace hearth inner lining apparatus that prolongs the campaign.
Background technology
Known have a kind of electronic simulation method can measure the temperature field of blast furnace furnace foundation.According to this method, measure the temperature field along the degree of depth of State of Blast Furnace pit, otherwise can judge the degree of depth in furnace bottom hole by the temperature on the furnace foundation axis.But this method can not be diagnosed the situation of basque under the blast furnace owing to lack the means of monitoring call parameter, can not guarantee the work that blast furnace is safe and reliable.
Domestic under the diagnosis blast furnace in the basque situation device, only bury a temperature difference heat galvanic couple underground in the outer lining brick in the same measuring point close to the furnace shell, the backup lining brick etch situation that can not reflect very thick [about 2 meters thick], the backup lining brick etch situation of having only the temperature difference heat galvanic couple of close inner lining of furnace brick just can reflect is when first temperature difference heat galvanic couple from the inner lining of furnace brick is fallen also to be fallen by etch simultaneously by etch with lining brick.Certainly, also have employing following basque axially on the measuring method of quantity n 〉=3 of each some thermopair, the influence of the measuring accuracy of aforesaid method because arranged by linearity still can not truly reflect the situation of backup lining brick etch.In addition, above-mentioned temperature difference heat galvanic couple corresponding protection system for want of under hot environment, also be very limited work-ing life.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art part and a kind of measuring accuracy height is provided, adaptability is strong, temperature difference heat galvanic couple long service life can guarantee the blast furnace safe and reliable operation and can reflect a kind of diagnosis blast furnace hearth inner lining apparatus of very thick backup lining brick etch situation.
For solving the problems of the technologies described above, the utility model is to realize like this.
A kind of diagnosis blast furnace hearth inner lining apparatus, it comprises basque, thermopair and CPU down; Described thermopair places down in the basque; The input terminus of the output termination CPU of described thermopair; Described thermopair is formed by being positioned at several thermopair measuring units that make progress in basque week down; Described thermopair measuring unit comprises first measuring unit, second measuring unit and the 3rd measuring unit; First measuring unit, second measuring unit and the 3rd measuring unit are equilateral triangle and distribute; Described thermopair is used for measuring the whole temperature of basque down; The temperature signal that described CPU automatic reception thermopair sends also and then is analyzed the situation of basque down.
As a kind of preferred version, the outside of first measuring unit described in the utility model, second measuring unit and the 3rd measuring unit is fixed with protection module respectively; Described protection module comprises vitrified pipe and suit alundum tube wherein; Between described vitrified pipe and alundum tube, be provided with graphite-filled dose of layer.
Domestic under the diagnosis blast furnace in the basque situation device, only bury a temperature difference heat galvanic couple underground in the outer lining brick in the same measuring point close to the furnace shell, the backup lining brick etch situation that can not reflect very thick [about 2 meters thick], the backup lining brick etch situation of having only the temperature difference heat galvanic couple of close inner lining of furnace brick just can reflect, when first first measuring unit from the inner lining of furnace brick is fallen also to be fallen by etch simultaneously by etch with lining brick, second measuring unit reflects backup lining brick etch situation again, until the 2nd fallen by etch after, the 3rd measuring unit reflects has answered blowing out changeable liner brick.In addition, distribute because first measuring unit, second measuring unit and the 3rd measuring unit are equilateral triangle, this array configuration is under the suitable situation of temperature-difference thermoelectric even number amount, and the measured zone that has expanded the temperature difference heat galvanic couple has improved measuring accuracy.The protection module that the outside of first measuring unit, second measuring unit and the 3rd measuring unit is respectively equipped with is to producing material impact the work-ing life that prolongs the temperature difference heat galvanic couple.Graphite-filled dose of layer can be adjusted the stress distribution between vitrified pipe and the alundum tube, prolongs the temperature difference heat galvanic couple purpose in work-ing life thereby reach.
