Description
Technical field
The present invention relates to continuous casting of iron and steel metallurgical technology field more particularly to a kind of intelligent multi-function metallurgy tundish and its
Casting method.
Background technique
Tundish as the last one refractory material containers during connecting big packet and crystallizer in continuous casting smelting process,
Tundish metallurgy is a special furnace outer refining technology, is the key link for obtaining high quality continuous casting billet.
During steel casting, tundish is other than stablizing beam, realizing sequence casting, it is often more important that plays promotion
The floating of field trash excludes and the important function of pure molten steel.And molten steel overheat stability in these key factors and packet
Control and tundish in uniform flow field reasonability it is closely bound up.In tundish metallurgy technical process, there is in this way
The point of one opposition: if wishing, the center segregation index of continuous casting billet is lower, then the degree of superheat of tundish is as low as possible, if but uncommon
Hope continuous casting billet field trash index it is lower, then the degree of superheat of tundish improve as far as possible be conducive to the collision of field trash and on
Transportation by driving is dynamic, therefore, the defects of in order to eliminate or reduce segregation and the field trash in continuous casting billet simultaneously, it is necessary to by the steel in tundish
Coolant-temperature gage controls in very narrow range, and external and most domestic steel mill is just trying through tundish channel type sense at present
Refining techniques should be heated to go to improve this problem, the tundish channel type induction heating apparatus gradually promoted and applied in recent years formally at
For a kind of most effective means of tundish temperature compensation and inclusion removal.
But in practical applications, most of steel mill's pouch-type be based on T-type tundish, if upper induction heating equipment,
So induction coil can only be arranged between the impact zone of Metal in Tundish and trough casting area, and induction coil is along big Bao Changshui
Mouth (big water-coating port is by steel device) casting direction center line arrangement, the induction channels of induction coil two sides are disposed to connect in splayed configuration
The molten steel of impact zone and casting area is connect, induction heating is carried out to molten steel to form a complete loop, it is contemplated that come into operation function
Rate is bigger, the security reliability of use environment, be bound to cause inductor take up space it is bigger, and under normal conditions, long water
Mouth drop point and submersed nozzle drop point spacing are generally between 800mm ~ 1200mm, for the stream of multithread odd number stream such as 5, especially
7 streams, there is the undesirable situations in intermediate flow flow field (as shown in Figure 1, middle part does not have flow field and is low-temperature space, tundish two sides
Having flow field is high-temperature region), in most cases, we must go to alleviate this problem by dam or weir, but for special steel
Metallurgical process, since the high temperature of molten steel washes away, these dams or weir also become a kind of pollution sources in fact.
It on the other hand, will be according to the technological requirements in entire continuous casting process for channel-type induction heating tundish
To control the power that comes into operation of induction heating.At continuous casting initial stage, since big Baogang's coolant-temperature gage is higher, induction heating tundish at this time
Hardly need come into operation it is high-power, and in the continuous casting middle and later periods, since big Baogang's coolant-temperature gage declines, although tundish accumulation of heat is abundant,
But the temperature decline of whole molten steel requires molten steel in tundish to need to open induction heating to supplement molten steel temperature drop.At this moment, intermediate
The additional effect of packet induction heating is just sent out as the pinch effect in the upper up-flow of temperature difference and channel goes to be mingled with effect
It waves, as patent CN104249149A refers to tundish induction heating cooperation channel Argon, it is intended to can apply in the full mistake of continuous casting
Removal of inclusions and uniform liquid steel temperature in journey.But this method solves only Process Problems, does not solve 5 stream of majority odd number stream, 7
The root problem in flow field is flowed, while channel Argon is equivalent to and also reduces the temperature that tundish goes out channel, certainly will weaken tundish
Induction heating self-temperature difference causes the additional effect of density upper up-flow.
Therefore, it develops in a kind of intelligent multi-function metallurgy tundish channel type induction heating and intelligent multi-function metallurgy
Between the packet electromagnetic agitation New Metallurgical Technology combined and the device of a set of feasibility be that we need research and development at present or even in the future
The integrated equipment being of great significance.
