Description
Technical field
The present invention relates to steel-making tundish thermometry field more particularly to a kind of steel-making tundish temperature tube, temperature-measuring guns
With thermometric robot and its temp measuring method.
Background technology
The service life of tundish is made steel from a few hours to tens of hours etc., due to high temperature, molten steel washes away, slag corrodes
The effects that, the tundish for having reached service life pours steel station since the damage of its refractory lining must be withdrawn from and is repaired.It repaiies
The tundish completed again must carry out roasting packet operation and can just be again introduced into pour steel working position.Roasting packet operation is generally divided into two ranks
Section：First stage dries packet for low temperature, and main purpose is the moisture sloughed in new lining up and coating.Second stage is high temperature
Dry packet, main function is on the one hand in order to thoroughly remove the moisture of the resistance to material of tundish and also to which to improve Bao Wen big to meet
The injection of Baogang's water.
Either low temperature dries packet in roasting packet operation or the high temperature baking packet stage has been required in real time unpacking bore temperature, this is
Because：(1) some refractory materials need during operation to avoid (or quickly crossing) to specific temperature section sensitivity, in order to avoid in this temperature
Rapid lapse of time dries packet operation and damages resistance to material.(2) when high temperature dries packet, packet bore temperature is usually required that no more than 1200 DEG C but is existed again
1100 DEG C or more maintain time enough.It is excessive, unfavorable to dry the too low molten steel temperature drop that first big packet can be caused injected of packet temperature
It is unwrapped in and pours or even cause wadding steel accident；Otherwise, dry packet temperature it is excessively high not only result in energy waste, can also the resistance to material of ablation lead
Cause tundish service life shortening, result even in resistance to material come off too early collector nozzle is caused to be blocked so as to further result in wadding
The generation of the accidents such as steel, bleed-out and excessive steel.
Generally seldom packet bore temperature is measured when China's tundish dries packet operation at present, in particular for packet bore temperature
It is continuous measure it is more rare.The reason of control of packet bore temperature generally all uses artificial experience control mode, forms this situation
The mainly shortage of packet thorax thermometry means.At present, the mode for measuring packet bore temperature can be attributed to following three kinds：
Firstth, dedicated infra red flame thermometer is utilized：
Tundish, which dries, wraps the fuel used general blast furnace gas or coal gas of converter being had by oneself using steel mill, due to being industrial process
Product, these combustion gas are not generally very clean.
Infra red flame thermometer is divided into as two-color thermometer (the infrared letter used using soot dust granule object as infrared signal source
Number frequency is at 0.7~1.1 μm) and be operated in carbon dioxide gas molecule characteristic infrared signal in band monochromatic thermometer
(infrared signal frequency is in a narrow-band centered on 4.5 μm).
Since fuel for combustion gas (and and unholiness) while lacks suitable measurement position, actual measurement shows：Both are special
Thermometer can not obtain the accurate temperature of packet thorax.
Secondth, quick thermocouple is utilized：
The greatest problem of this thermometric mode is can not to obtain the continuous temperature value of packet thorax, therefore can not achieve and dry packet operation
When packet bore temperature automatically control.And when big fire is dried and is wrapped since the radiation temperature in tundish certain distance is especially high, work
People is difficult to close to tundish, completes quick thermocouple thermometric operation difficulty.
Third utilizes Continuous Temperature Measurement of Liquid Steel in CC Tundish device：
Some steel mills also once measure packet bore temperature when drying packet using Continuous Temperature Measurement of Liquid Steel in CC Tundish device.But molten steel connects
Temperature tube is commonly aluminium carbon pipe (either its thermometric of infrared temperature measurement apparatus or thermocoupling temperature measuring device used by continuous temperature measuring equipment
Pipe outer tube is all aluminium carbon pipe), aluminium carbon pipe can be caused to be exposed in the flame full of air when drying packet operation, so as to cause temperature tube
Quick decarburization and be thus greatly lowered the service life of temperature tube and the performance in the measurement of subsequent liquid steel temperature with
Using effect, aluminium carbon pipe is expensive so that thermometric cost is excessively high in addition.
Through retrieval, Chinese patent application, application number：201510515183.5 publication date：2015.11.25, one is disclosed
Kind tundish temperature measuring equipment, including pouring basket lid, further includes mounting flange, guide pipe, temperature probe and temperature detector are described
