Summary of the invention
The utility model purpose provides that a kind of temperature-measuring range is wide, thermometric accurately, Stability Analysis of Structures, not fragile, the temperature measuring equipment of the continuous measuring high-temperature copper liquid temperature that cost is low.
The technical solution of the utility model is: be used for the last protection tube of the temperature measuring equipment of continuous measuring high-temperature copper liquid temperature by the copper tube material; the following protection tube of graphite-pipe material; nickel chromium-nickel silicon thermocouple; asbestos rope; mix magnesia; porcelain bushing shell; fixing porcelain tube; compensating wire and intelligence instrument are formed; following protection tube closely is placed on the protection tube; following protection tube immerses in the copper liquid; thermopair places protection tube inside; its welding end is positioned at protection tube down; and the welding end that makes thermopair stretches out upward protection pipe end port one segment length of joining with following protection tube; should make thermopair welding end distance be not less than 30 millimeters in the protection tube bottom down simultaneously; the nickel filament of thermopair and nisiloy silk are put on some porcelain bushing shells from top to bottom successively; filled stone cotton cord between last protection tube inboard and the thermopair; fill in the following protection tube and mix magnesia; make the thermopair welding end fix and be embedded in middle the mixing in the magnesia; and placed copper liquid surface sintering 5～10 minutes; free-ended nickel filament of thermopair and nisiloy silk are fixed in the protection tube other end with fixing porcelain tube; with compensating wire the free-ended nickel filament of thermopair is linked to each other with the both positive and negative polarity of intelligence instrument respectively with the nisiloy silk then; place copper liquid after 10 minutes protection tube bottom under this device, the temperature that thermoelectric effect that can be by thermopair is accurately read certain depth copper liquid in the stove from the intelligence instrument.
The utlity model has following advantage:
(1) simple in structure, durable, make easily;
(2) thermometric is accurate, and error is within ± 5 ℃.
(3) temperature-measuring range is wide, but the people is from 0 ℃～1280 ℃;
(4) long service life, can be in copper liquid continuous temperature measurement more than month;
(5) temperature measuring equipment shock resistance and anti-sootiness, dust disturb extremely strong, have therefore guaranteed the precision of thermometric;
(6) composition material is common, and price is quite cheap.
This device can solve the key technical problem of present line-frequency induction melting furnace thermometric robot control system(RCS), and production run is carried out accurate instruction, guarantees product quality, improves electric furnace output, cuts down the consumption of energy, and prolongs furnace life, improves the production economic benefit.
