Description
Technical field
The utility model relates to a kind of device for obtaining at least one measured value on smelting furnace, and wherein, this device comprises: at least one is used for spraying into to smelting furnace the device of at least a gas; And at least one is used for obtaining the measuring unit of at least one measured value.The utility model also relates to a kind of smelting furnace, particularly electric arc furnaces, and wherein, at least one is introduced in furnace chamber for the furnace wall that the device that sprays at least a gas to smelting furnace passes smelting furnace.
Background technology
At smelting furnace, for example electric arc furnaces, ladle furnace, exhaust equipment, or during the work such as the molten groove of other secondary metallurgical device, glass, importantly can obtain to show the specific measured value of the feature of smelting furnace duty or melting duty on the time point of each expection.Can be by contact type measurement, for example realize measuring by manually obtaining measured value and sampling, or optionally by contactless measurement, for example, realize measuring based on vibration or electromagnetic radiation that processed object, liquation or smelting furnace itself sends.
For example, in order to input energy in furnace chamber, in order to accelerate the melting process in electric arc furnaces, in order to carry out refining etc. to soaking metal, being permitted eurypalynous smelting furnace, particularly metallurgic furnace (for example, electric arc furnaces) has and is assemblied in device on furnace wall, that be used at least a gas is injected to smelting furnace.This device at least a gas being injected to smelting furnace can be burner unit, burner-jet pipe unit, jet pipe unit and similar device.Burner unit produces flame in the burner pattern.At this, fuel, particularly natural gas, oil and similar fuel are in the situation that burn with the oxygen mix that contains fuel gas.
For for example carry gas, as being used for the oxygen of refined metals liquation, in order to obtain a plurality of measured values or sampling, jet pipe is inserted in furnace chamber on the mostly just time limitedly and partly.Yet also known a kind of jet pipe unit of assembling regularly, this unit is fixed on smelting furnace.
EP1457575B1 has described and has started device described type, that in the melting course of work, the loaded objects in electric smelter is observed.For this reason, burner unit is equipped with the infrared camera of camera, particularly spectroscopy, and this camera is arranged in the Temperature Distribution situation in burner unit inside and acquisition furnace chamber.
Except traditional, only can carry out under the burner pattern the burner unit of work, also known during this period a kind of combustor nozzle unit, this unit with burner unit and jet pipe unit associations together, wherein, this unit can alternately carry out work under burner pattern or jet pipe pattern.
As in traditional burner unit and combustor nozzle unit, when work under the burner pattern in these unit, it produces flame and energy is input in furnace chamber.But burner-jet pipe unit can be after the burner pattern be closed, and is used as jet pipe after that is to say fray-out of flame, can spray into air-flow and obtain measured value in furnace chamber by this jet pipe.For this reason, connector on being arranged on traditional burner unit, that be used for fuel and combustion gas, also be provided with extraly at least a gas that is injected into gas connector used under the jet pipe pattern on the combustor nozzle unit.
Also assembled measuring unit at this burner-jet pipe on the unit, this measuring unit obtains measured value with passing burner-jet pipe unit optically at the upwardly extending pipeline in the side of furnace chamber in furnace chamber.
Can find out, when for example maybe needing measuring unit with other type to obtain other measured value due to fault, can change comparatively continually the measuring unit on smelting furnace (particularly electric arc furnaces).Owing to reorientating accurately, so the location of new measuring unit is costly.For example, under the jet pipe pattern, be positioned at the jet cone mouth (Lanzengaskegel) and the transitional region between furnace environment that construct and do not allow to conflict mutually with the measuring position of measuring temperature, because this can cause measure error.In addition, for furnace operation personnel's safety, need to carry out non-dangerously smelting furnace that measuring unit the changes state that quits work.Time delay and unexpected off-air time when the above-mentioned whole circumstances all cause smelting furnace work.Improve thus the working cost of furnace equipment and reduced the output of smelting furnace.
The utility model content
Thus, the purpose of this utility model is, a kind of device that starts described type is provided, and during measuring unit on changing smelting furnace, this device has been guaranteed effective smelting furnace work; And provide a kind of smelting furnace with this device.
