Description
Technical field
The invention belongs to metallurgical industry detection technique field, and it is quick to specifically provide a kind of stokehold steel grade liquid-solid phase line temperature
Detection means and method.
Background technology
Steel grade liquidus temperature and solidus temperature are that (liquidus temperature is for two important technical parameters of smelting and casting
For steel grade in the critical transition temperature of the solid mixed phase of single liquid phase and liquid, solidus temperature is steel grade in the solid mixed phase of liquid and single solid
The critical transition temperature of phase), for ensureing melting and cast article quality, saving energy consumption, reduction disposal of pollutants meaning weight
Greatly.
In melting and casting, it is necessary to more than heat steel to liquidus temperature melting will be carried out, then in some temperature
Tapping is cast.Molten steel overheat (liquid steel temperature is higher by the part of liquidus temperature) can neither be too high, again can not be too low.Such as
Fruit is too high, can increase melting and casting time, wastes the energy needed for melting heating, increases the discharge of pollutant, make in strand
Heart segregation aggravates or green shell is relatively thin and cracked；If it is too low to cross the degree of superheat, molten steel is easily polluted by field trash, while easily makes
The mouth of a river occur to block and even freeze (Cen Yongquan, season influence Shanghai Metals of the great writer continuous casting steels degree of superheat to casting blank solidification
.1999,21(6):21‐24).In Continuous Casting Soft Reduction technique, in order to preferably determine the position of slighter compress near solidification zone, need
Accurately to obtain the solidus temperature of continuous casting billet.Accordingly, it is determined that liquidus temperature and solidus temperature are the weights of melting and casting
Work.
The determination method of liquidus curve and solidus temperature has equation, laboratory thermal analysis system.It is summarized as follows respectively：
1. equation
Method used in production scene is mainly equation at present, even if being the multinomial of independent variable to each element content
Formula formula calculates liquidus temperature and solidus temperature respectively.But formula is typically only capable to adapt to certain trade mark；It is and right
In the given trade mark, certain composition range can only be adapted to again；Also exist and caused due to the error of each element composition measurement value
Calculation error, error is very big sometimes.
Document (support the army, the calculating of the liquidus temperature of steel, 2002,14 (6) by force:It is public 6-9) to report 4 kinds of liquid phase line computations
Formula, for first three respectively for general steel grade, carbon steel and special steel, latter is the modified formula of document author, these
Their precision in each adaptive range are respectively -15~5 degree, and 4 degree, well (document does not provide specific precision to precision
Value), -4~2 degree.
Document (Feng Ke, Han Zhiwei, Wang Yong, Mao Jinghua, the theoretical prediction and regression analysis of the actual solidus temperature of carbon steel,
Foundry engieering 2007,28 (7):937-939) report a kind of solidus temperature calculation formula for carbon steel, this formula and text
Offer (Hou Zhihui, Zhang Yanliang, Cui Rong, 45 steel production practices, Tianjin is metallurgical, and 2007,6:4-6) it is used for calculating a kind of 45 steel (carbon
Steel) formula it is different.Document (Hou Zhihui, Zhang Yanliang, Cui Rong, 45 steel production practices, Tianjin is metallurgical, and 2007,6:Public affairs 4-6)
Formula and document (Cai Kaike, continuous casting steel machine, Beijing:Science Press, 1990:264) first formula is identical, and (Cai opens document
Section, continuous casting steel machine, Beijing:Science Press, 1990:264) there is second formula, and calculate the formula of solidus temperature.
The present inventor is had found by calculating, and it is very big to calculate the result difference of No. 45 steel solidus temperatures with this three formula.For 45
Steel lower limit composition steel grade (C 0.42%, Si 0.17%, Mn 0.5%, P 0%, S 0%, Cu 0%, Cr 0%Ni 0%),
Solidus temperature is respectively 1416.5 degree, and 1356.1 degree, 1431.6 degree, three at most differs 75.5 degree；For upper limit component steel
Kind (C 0.5%, Si 0.37%, Mn 0.8%, P 0.035%, S 0.035%, Cr 0.25%, Ni 0.25%, Cu
0.25%), solidus temperature is respectively 1333.5 degree, and 1306.1 degree, 1374.4 degree, three at most differs 68.2 degree；For flat
Equal composition steel grade (C 0.46%, Si 0.27%, Mn 0.65%, P 0.0175%, S 0.0175%, Cr 0.125%, Ni
0.125%, Cu 0.125%), solidus temperature is respectively 1431.6 degree, and 1375 degree, 1403 degree, three at most differs 71 degree.
Document (K.Gryc, B.Smetana, K.Janiszewski, et al.Thermal analysis results
and the theoretical determination of solidus and liquidus temperatures for
the grain oriented electrical steel,Solid State Phenomena,2015,vol 226:209-
214) report employ 13 kinds of liquidus temperature calculation formula and 2 kinds of solidus temperature calculation formula calculate respectively it is same special
The liquidus temperature and solidus temperature of steel.Result of calculation shows：On the basis of thermal analysis system measurement result, 13 liquidus curve public affairs
The calculating deviation of formula is spent from 0~-118；The calculating deviation of 2 solidus calculation formula is respectively 3 and -48 degree.
In addition to above-mentioned document, the present inventor once investigated in the special steel production scene of tool of production steel and mould steel, technique people
Member points out that, for same kind, because formula selects difference, when calculating liquidus temperature, calculated value differs tens degree each other
Even more than 100 degree, such case are more common for new varieties.And in the special steel production of another production spring steel and wire rod
Scene, technologist also indicate that, select difference for formula, the calculated value of solidus temperature differs greatly；Even with same
Formula calculates, and solidus temperature at least has 20 degree of deviation, and this deviation causes the technique of Continuous Casting Soft Reduction to tend to be conservative.
It can see from document above and Field Research, be supplied to the liquidus temperature and solidus temperature of onsite application at present
Formula is spent, also there is applicability and precision problem, it is difficult to meets the growing technological requirement in production scene.
2. laboratory thermal analysis system
That compareed with equation formation is laboratory thermal analysis system (P.K.Gallagher, Handbook of thermal
analysis and calorimetry,Principles and Practice,Elsevier,1998).Laboratory heat analysis
Method, it is to use laboratory thermal analyzer, such as DTA (differential thermal analysis)/DSC (differential scanning calorimetric)/Direct TA (directly heat
Analysis) equipment measures the method for liquidus temperature and solidus temperature, typically used by R＆D institution.This kind of method it is excellent
Point is higher (K.Gryc, B.Smetana, K.Janiszewski, et the al.Thermal analysis of measurement accuracy
results and the theoretical determination of solidus and liquidus
temperatures for the grain oriented electrical steel,Solid State Phenomena,
2015,vol 226:209-214), weak point is equipment purchase, higher (equipment 30~500,000 of the cost of operation and maintenance
RMB；Equipment needs special equipment operator；Operating personnel can worry the high temperature resistant component of equipment because being heated to high temperature
And accelerated ageing or damage, do not receive test of the liquidus temperature in 1450 degree or more steel grades typically), and measure a not good liquor
The time that phase line or solidus temperature are spent is long, it is often necessary to 2~4 hours or longer time, but also not very by producing
Time (it is generally necessary to 2~3 days) between scene and R＆D institution needed for transfer samples.For the occasion that the time is more critical,
For example produced on-site quickly gropes new grades technique, or occur quickly check etc. after quality problems, experiment to the existing trade mark
Room thermal analysis system seems too slow.
In summary, equation is calculated fast but accurate dependent on the trade mark and constituent content, laboratory thermal analysis system but measured
Time is grown.
