Description
Technical field
The invention belongs to continuous casting process, more particularly to a kind of thin strap continuous casting cloth streaming system and its operational method.
Background technology
For twin-roll thin strip continuous casting technology as a kind of short route metallurgical technology technology, typical production process is shown in Fig. 1.It is thin
Band continuous casting typical process is specific as follows.The molten steel of melting is injected molten steel in current distribution device 4 by the mouth of a river 6 of 5 bottom of tundish, is led to
Crossing current distribution device 4, equably cloth stream forms molten bath in the space that two casting rolls 1a, 1b and side seal board 2a, 2b are surrounded by molten steel,
Casting roll 1a, 1b rotates, and molten steel forms Thin Strip Steel at the two minimum gap.
Wherein, thin strip continuous casting stream distribution device be used for by molten steel equably cloth stream in two casting roll roll surfaces, which is fire resisting
Material manufacture is aluminium carbonaceous or quartziferous etc..If current distribution device temperature is too low, the surface steel bonding in current distribution device can be caused, generated cold
Bloom etc. influences thin steel strip quality.In order to avoid above-mentioned unfavorable phenomenon, before casting operation, need current distribution device being heated to 900-
1300 DEG C, and it is installed in operating position in a short time, avoid heat loss.
In twin-roll thin strip continuous casting technique, cloth streaming system includes mainly tundish and current distribution device has baking according to its process function
The groundworks positions such as roasting position, casting position.
Current distribution device using it is middle exist toast uniformity be difficult to ensure, heat insulation effect in transportational process between each operating position
The problems such as poor.In the current distribution device application method designed in current open source literature, it is concentrated mainly on simple modular construction design
And improve its cloth stream uniformity etc., how will toast position heat preservation and sealing, the molten bath heat preservation of casting position and sealing, promptly walk
The methods of loss is reduced when row not yet.
A kind of current distribution device installation as described in Chinese patent CN102049482 and application method.It utilizes hanging mechanism
Current distribution device is hung in tundish lower part, can be moved with tundish.Baking tundish toasts current distribution device simultaneously, and oven can be with
Independent control baking temperature, baking terminate current distribution device as tundish reaches casting position, current distribution device are placed on operating position
On holder, hanging mechanism is detached from current distribution device, followed by casting operation.
Invention content
The purpose of the present invention is to provide a kind of thin strap continuous casting cloth streaming system and its operational methods, can shorten current distribution device and exist

Casting position, the tundish are located at current distribution device above casting roll, carry out casting operation；
Wherein, when the cloth streaming system is in the baking position, current distribution device is placed on the baking of the long slot structure in oven
On roasting holder, current distribution device lid is placed on oven, and a sealing thermal insulation space is formed in oven, and it is closed to play heat preservation
Effect；
When the cloth streaming system is in the casting position, current distribution device be placed on the current distribution device supporting rack above casting roll it
In, the molten bath that casting roll is formed with side seal board will be injected by current distribution device described in the molten steel in tundish, and then below casting roll
Form thin steel strip；At this point, current distribution device lid is located above current distribution device, bottom is in contact with current distribution device supporting rack upper surface, to
Sealing thermal insulation space is formd on current distribution device top；And casting roll top of the current distribution device supporting rack on the outside of current distribution device is formed
Sealing, to realize sealing space on molten bath top.
12. the operational method of thin strap continuous casting cloth streaming system as claimed in claim 11, characterized in that in the cloth streaming system
When in casting position and baking position, between the supporting plate bottom of the connecting rod lower end and cover board upper surface presence
Gap.
13. the operational method of thin strap continuous casting cloth streaming system as claimed in claim 11, characterized in that the current distribution device lid two is hung
Two lifting lugs of tool upper end will fall off after being hampered in two suspension hooks being symmetrically installed from the tundish bottom, to make the current distribution device
Lid, current distribution device and tundish are detached from.
14. the operational method of the thin strap continuous casting cloth streaming system as described in claim 11 or 12, characterized in that the strip connects
On the tundish car that casting cloth streaming system moves between being placed on baking position and position of casting, which moves between the two positions
It moves and is risen or fallen with cloth streaming system.
