The specific embodiment
Here, as illustrated in fig. 1 based on such imagination, i.e. basis
Poring rate
The cast width
Cast thickness
Cast specification (circle, abnormal shape etc.)
The cast ability
The tundish design
The tundish degree of filling
The tundish lining
Tundish technology
The ladle situation, and in order to carry out the uncovered continuous casting of molten steel of oil lubricating type or to have immersion cast gate/pouring spout and the continuous casting of the lubricated powder of crystallizer, must be controlled at the liquid steel temperature in crystallizer (1) the cast liquid level (2) and make it to keep to stablize constant.The crystallizer cast interior liquid steel temperature of liquid level (2) (2.1) must equal under any cast situation on symmetric points of determining according to mold shape:
T
ML=T
Li+ X ℃ (X=5-15 ℃), T
Li=f (steel grade) (2.1)
In addition, what here to point out is that the above-mentioned condition of in check potting syrup surface temperature (2.1) can be used to any steel grade.
In order irrespectively to guarantee pouring condition with presumable cast situation (2.1), need correctly recognize the liquid steel temperature loss, this temperature loss is played tundish (3), is used the second metallurgy equipment (4) at a ladle furnace (4.1) and a for example application of vacuum station (4.2) from cast liquid level (2), up to tapping (5), as the tapping of BOF (converter) (5.1) or E stove (5.2).
The loss of steel temperature in this explained hereafter chain is subjected to the strong influence of the type of time of molten steel and temperature and stove and refractory lining thereof and state (service life, wearing and tearing, heat conduction compare etc.).
Therefore, for example tundish (3) and ladle (4.3) can be considered as heat exchanger, it decides than type, age or the state of wear of thermal parameter by furnace lining.
What also must consider is, concerning rise to annotate promptly one unsettled and also be not in the process section in the hot-fluid balance, it is characterized by in the transition of thermal capacity when molten steel stays in the ladle, between ladle and tundish of the empty tundish (3) of heat time heating time, heating-up temperature and ladle course (7) and ladle (4.3) and in tundish itself, all liquid steel temperature loss had a significant impact.
Under the situation of second ladle to the n ladle in a cast sequence, tundish is in the constant thermal balance of heat loss, and also causes different heat loss as the ladle of " individuality ".
According to working experience, past attempts is being estimated as in conticaster (1.1) is regional and separations tundish (3) in tapping (5) and temperature loss between the second metallurgy equipment (4) that uses ladle furnace (4.1), and in addition qualitative consideration in technical process.
Therefore, in order to pour into a mould controllably, from desirable liquid steel temperature T
ML=T
LiRise+X ℃ (2.1), determines the liquid steel temperature of desirable tundish (3.1) for planned poring rate and planned cast specification.Tundish temperature (3.1) comes corresponding adjusting by the understanding to the temperature loss between ladle furnace and the tundish (4.1.1).It is shown in Figure 3 that melting plan is seen, it in cast liquid level (2.1) liquid steel temperature and relevant with poring rate (6) (seeing component 3a) and up to second metallurgy equipment (4) zone as the tapping temperature on the ladle furnace LF-ex (4.1) be expressed as in tundish equivalent liquidus temperature T °
Li(3.1), it has auxiliary temperature+5,10 ℃, 15 ℃, 20 ℃ (3.1.1).Tapping temperature at the ladle furnace place determines that by ladle course (7) this ladle course has two significant effects scopes:
The time of staying (7.1) of molten steel in ladle, tap so that water from the ladle of tapping,
" ladle is full ";
Ladle does not have the time period of molten steel (7.2) or " ladle sky "
Also by tundish course (3.2) decision, its material impact parameter is tapping temperature:
Tundish preheat temperature (3.2.1)
Tundish preheating time (3.2.2)
Tundish circulation timei (3.2.3) is together with its specific preparation.
Fig. 4 represents a kind of suitable ladle recognition system (8), and it self utilizes an orifice plate (8.1.1) to a radiation sensor (receiver) code radiometric (8.1.2) based on the ladle wall.
Fig. 1 is illustrated in the whole explained hereafter chain between tapping (5) and the continuous cast mold (1).Now, in order can according to plan also at first to be that tundish also is ladle furnace LF-ex control liquid steel temperature subsequently " online ", must know from desirable cast liquid level liquid steel temperature (2.1):
The cast parameter reaches here
The relation of liquid steel temperature and poring rate (6) is seen TT/VC-system (10) in the tundish
Described (referring to Fig. 2) is when given cast ability or the stop of the molten steel in the tundish
Between situation under;
Tundish course (3.2) and preheat temperature (3.2.1) and preheating time (3.2.2),
And tundish circulation timei (3.2.3), comprise that possible standard work is equipped with as upgrading, spraying
Mend refractory matter, drying time or the like and
Ladle course (7), it comprise molten steel in ladle the time of staying (7.1) and all the other
The ladle time (7.2), at this moment between in, do not have molten steel in the ladle; And ladle
State (7.3), the ladle state is determined by following factors:
The age of ladle lining (wearing and tearing)
The type of ladle lining.
Ladle course (7) is made up of following factors according to this:
" ladle the is full " time in other words, begins time to ladle furnace tapping from tapping, and its maximum time before the cast beginning is as being the longest 25 minutes (7.1),
" ladle sky " time (7.2)
Ladle state (7.3)
Wherein, the time of the time of " ladle is full " (7.1) and " ladle sky " (7.2) constitutes normal ladle circulation timei (7.4).
In (7.2) time, ladle experiences different disposal such as cleaning (7.2.1) at " ladle sky ", and (7.2.2) is ready to flashboard in order to come into operation next time.In addition, also can from ladle circulation, take out ladle,, perhaps also can serve as a contrast maintenace point (7.6) and go up and repair the ladle lining at ladle so that on a hot spot (7.5), heat when idle long-time.
In order to grasp many influence factors, these influence factors are to ladle generation effect and finally have influence on temperature loss (4.1.1) between ladle furnace and tundish thus, in ladle cycle period (7.4), set up ladle recognition system (8) on the place relevant with definite ladle course (7), it is preferably by a coding ladle radiation appliance (8.1) based on ladle self radiation.Utilize such measuring system, can note motion and elementary errors sequential in the zone of " ladle is full " (7.1), " ladle sky " (7.2), so that according to these measurement data temperature loss (4.1.1) between ladle furnace LF and the tundish is among the functional relation subsequently.
Situation similar to ladle is exactly rising to annotate and give special concern the cast sequence that is made of a plurality of ladles in the tundish economic limit.Here, the temperature loss (4.1.1) between LF (4.1) and tundish (3) superposes with tundish course (3.2) once more, and the tundish course comprises:
Tundish preheat temperature (3.2.1)
Tundish preheating time (3.2.2) and
Tundish circulation timei (3.2.3)
Tundish drying time and temperature (3.2.4)
Tundish lining (3.2.5)
Fig. 2 represents the liquid steel temperature course, it from E stove (5.2) or BOF (5.1) through ladle furnace LF-ex (4.1) and up to the cast liquid level (2) of crystallizer (1).Plan liquid steel temperature in the cast liquid level (2.1) has provided and has been used in the tundish and the basis of the temperature plan on the ladle furnace LF-ex (4.1).
From the cast liquid level to the jump in temperature of tundish (9) or from tundish to the temperature loss of pouring into a mould liquid level is concreting thickness and the decision of cast width by poring rate (6) and cast ability basically.
On the contrary, the jump in temperature from tundish to ladle furnace (4.1.1) is basically by ladle course (7) and tundish course (3.2) decision.
Fig. 3 is divided into partial graph 3a, 3b.In component 3a, relatively show tundish temperature (3.1) TT poring rate (6) VC, this is at the equivalent liquidus temperature T ° li of the molten steel in the tundish (3.1.1), its auxiliary temperature (3.1.1.1) is T ° of li+5,10,15,20 ℃.
For example, be 5 meters/minute if establish poring rate, then draw 1560 ℃ tundish temperature (10), this temperature is regarded as the desirable liquid steel temperature (10.1) in the tundish concerning Tli=1530 ℃ steel grade, that is: TT=Tli+10 ℃ (VC=5 rice/minute)
For reaching, shown in component 3b, determine the liquid steel temperature transition (4.1.1) between tundish and the ladle furnace LF-ex (4.1) as 1560 ℃ of ideal temperatures (10.1).
Here, in following condition is that tundish is preheating to 1100 ℃ (3.2.1.1) and tundish and is preheating to 1200 ℃ (3.2.1.2) down and at the 2nd and n ladle (3.2.1.3) of a cast sequence, show temperature loss (4.1.1) ladle that is contrasting the time effects factor and be used for watering (7.1) molten steel
This figure is clear to be shown, at first ladle of a cast sequence and follow-up ladle show with ladle (7.1) in the molten steel time of staying and the relevant temperature loss of tundish preheat temperature (3.2.1).In addition, this temperature loss also relevant with remaining ladle course (7) and can utilize described method to be measured " online ".
