Analysis method.Early stage drippage degree experiment it is more original, heated using high-temperature heating element, using coke it is rebasing and covering, so
Time and the temperature of drippage, manual record are observed afterwards.It cannot there are the iron ore in testing furnace and the low situation of slag
It is observed in time, and continuously record data and can not preserve, it is unfavorable for the experimental analysis to the working of a furnace.
It with the development and progress of technology, can be shone in burner hearth using specific camera, when being heated to certain temperature
When spending, the refractoriness of refractory material can divide process by the bending of observation cone and be measured.It can also with this principle
For the measure of ore or clinker drippage degree, the drippage process in stove can obtain continuously with being recorded in computer for camera
Data, and corresponding with temperature, these continuous data informations are easily preserved, replicate, are recorded.
In terms of the document of retrieval：China Patent No. is the document of CN201510762333.2, discloses one kind《Melting drippage
The dress quadrat method of experiment》, include the following steps：A, new graphite crucible is taken, is placed in stand for experiment, coke upper surface is whole
It pats whole；B, dress sample container is taken, the internal diameter of the dress sample container is consistent with the internal diameter of graphite crucible, and fills the depth of sample container intracavity
Spend for 70mm, sample filled into sample container, by sample upper surface arrange it is smooth after, it is ensured that the mouth of specimen surface and dress sample container
Portion flushes；C, the sample filled in sample container is put into graphite crucible, and specimen surface is arranged smooth；D, it is 10- to take 40g granularities
12.5mm coke is laid in specimen surface.This method after loading sample once by just disclosure satisfy that requirement of experiment, without repeatedly adding
Additional examination sample and measurement, so as to save experimental period.A kind of test method by the use of coke as reducing agent is provided to document,
The environment of dropping performance, atmosphere, pressure can not be simulated, also without reference part.
China Patent No. is the document of CN201120163345.0, CN201110132000.3, though it being capable of Accurate Determining object
By the use of the temperature of material as iron ore reflowing temperature, drippage temperature, the accurate of drippage temperature is greatly improved in the temperature of material
Degree improves the accuracy of molten drop time point determining, is accurately captured temperature, the pressure curve at molten drop moment.Although this device
Iron ore reflowing temperature, drippage temperature can be measured, but not intuitive, process can not be observed.
China Patent No. is the document of CN201220219720.3, is disclosed《A kind of iron ore melting drippage experiment dress
It puts》, including graphite crucible, graphite pressurization lever apparatus, graphite heating device, burner, sampling cabinet, column and pressure rod lifting
Device；Graphite crucible is placed in the burner hearth of graphite heating device, and graphite pressurizes lever apparatus to the iron ore pressurization in crucible；Add
Compression bar lifting gear is used to that graphite pressurization lever apparatus to be driven to move up and down in graphite crucible body；Burner position is used for burning graphite
The exhaust gas volatilized in heating unit；The melting iron ore that sampling cabinet drips for undertaking；It is equipped on graphite pressurization lever apparatus
Load sensor, manograph, temperature measuring equipment and displacement meter.The utility model is metallurgical laboratory special equipment, for simulating reality
Test the measure of iron ore melting drippage performance parameters under the conditions of room.Iron ore, which melts drip apparatus, can realize the quick of iron ore performance
It measures, the plant automation degree is high, experimentation is very easy to operate, good airproof performance, human factor are smaller, experimental repeatability
It is high.But the soft process of melting can not be observed to ore.
China Patent No. is the document of CN201510222557.4, is disclosed《A kind of blast furnace furnace charge soft melting dropping is special
The assay method of property》, sample is made in ready blast furnace feeding mixture charge, is then charged into graphite crucible, bottom and upper
Layer respectively spreads coke button, then the graphite crucible equipped with mixture charge sample and coke button is fitted into iron ore soft melting dropping experimental rig
It is measured.The document can accurately obtain the high temperature soft melting dropping characteristic for meeting the blast furnace furnace charge of blast fumance reality,
So as to help the worker of smelting iron accurately held in practical blast furnace ironmaking production the structure of blast furnace melting with soft, position and
Thickness；Since these data of the structure of blast furnace melting with soft, position and thickness are all that can directly affect upper blast furnace lump zone
The important parameter of distribution and the indirect reduction of blast furnace furnace charge, the consumption of coke and smooth operation of furnace of Gas Flow, therefore,
Implementing technical scheme of the present invention can ensure that blast furnace realizes high yield, high-quality, low consumption productive target.The invention can not the company of display
Continuous delta data, and have deviation without pressue device, and time of day.
