Abstract
The utility model provides a feed tip nozzle for aluminum and aluminum alloy continuous casting and rolling machines, which comprises an upper nozzle leaf and a lower nozzle leaf, both sides of the lower nozzle leaf are respectively provided with a side check block, and refractory heat-preserving nuts are respectively arranged in the upper nozzle leaf and the lower nozzle leaf; bolts are screwed in the refractory heat-preserving nuts; and the bolts are connected with a feed tip carrier. Because the utility model dispenses with inner check blocks in the nozzle cavity, the turbulence of melted aluminum caused by the inner check blocks is eliminated, and thereby the quality of strips is improved.
Description
Technical field
The utility model belongs to field of metallurgy, relates in particular to a kind of aluminium and aluminium alloy continuous casting milling train lip.
Background technology
Lip is a final confession stream part of injecting crystallizer (roll gap between two rolls) in aluminium and the aluminium alloy continuous casting rolling plant moulding system.At present, the lip that is used for casting and rolling machine is by mouth fan, limit portion block, inner block are formed the lower refractory material of its material employing intensity up and down, for preventing the distortion of upper and lower mouth fan, portion is provided with block within it, and aluminium liquid flows through from the mouth chamber between the block, injects crystal region, aluminium liquid when the mouth chamber because the barrier effect of inner block, can produce the turbulent phenomenon of aluminium liquid at the front end of each block, thereby make strip produce aberration, influence the quality of strip with respect to the position of block.
Summary of the invention
The utility model provides a kind of aluminium and aluminium alloy continuous casting milling train lip, has solved the turbulent phenomenon of aluminium liquid in the background technology, influences the shortcoming of strip quality.
The technical solution of the utility model is achieved in that a kind of aluminium and aluminium alloy continuous casting milling train lip, comprises the mouth fan, following mouth fan, and limit portion block is established on following mouth fan both sides respectively, establishes the fire resistant heat preserving nut respectively in last mouth fan, the following mouth fan body;
Described fire resistant heat preserving nut is equipped with bolt;
Bolt links to each other with feed mouth carrier.
The beneficial effects of the utility model are: the utility model has been cancelled the inside block in the mouth chamber, has eliminated the turbulent phenomenon of the aluminium liquid of inner block generation, has improved the strip quality.
Description of drawings:
Fig. 1 is a lip contour structures schematic diagram;
Fig. 2 is the internal structure schematic diagram of traditional lip;
Fig. 3 is the utility model structural representation;
Fig. 4 is a mouth fan partial cutaway schematic under the utility model.
Part explanation: 1, go up the mouth fan; 2, mouth is fanned down; 3, limit portion block; 4, bolt; 5, fire resistant heat preserving nut; 6, inner block.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of aluminium and aluminium alloy continuous casting milling train lip, comprise mouth fan 1, following mouth fan 2, following mouth is fanned 2 two ends and is established limit portion block 3 respectively, and last mouth fan 1, following mouth are fanned and established a plurality of fire resistant heat preserving nuts 5 in 2 bodies respectively, and fire resistant heat preserving nut 5 is equipped with bolt 4, bolt 4 is fixedlyed connected with feed mouth carrier, the mouth fan is unlikely to distortion about making, and last mouth fan 1, following mouth are hollow between fanning 2, no block in the lip chamber.
Aluminium liquid enters lip by preceding case, and freely distributes in the mouth chamber, and is steady for levelling because no block hinders in the mouth chamber, do not have turbulent phenomenon, improved casting strip quality effectively.
Claims (3)
1, a kind of aluminium and aluminium alloy continuous casting milling train lip comprise mouth fan (1), following mouth fan (2), and limit portion block (3) is established on following mouth fan (2) both sides respectively, it is characterized in that mouth fan (1), establishes fire resistant heat preserving nut (5) respectively in mouth fan (2) body down.
2, a kind of aluminium according to claim 1 and aluminium alloy continuous casting lip is characterized in that described fire resistant heat preserving nut (5) is equipped with bolt (4).
3, a kind of aluminium according to claim 1 and 2 and aluminium alloy continuous casting lip is characterized in that bolt (4) links to each other with feed mouth carrier.
