Twin-roll cast-rolling device for aluminum alloy clean production and deep processing

Abstract

The invention discloses a twin-roll cast-rolling device for aluminum alloy clean production and deep processing. The twin-roll cast-rolling device comprises an oil absorption mechanism and a tractionwinding mechanism, and further comprises a cast-rolling mechanism, wherein the oil absorption mechanism is arranged on one side of the cast-rolling mechanism, and the traction winding mechanism is arranged on the side, far away from the cast-rolling mechanism, of the oil absorption mechanism; and the cast-rolling mechanism comprises a supporting table, a tundish, a discharging die, a cooling assembly and a forming assembly, and the tundish is connected to the top of the supporting table through bolts. According to the twin-roll cast-rolling device for aluminum alloy clean production and deep processing, the cooling assembly absorbs heat of liquid inside the discharging die, so that the liquid is solidified inside the discharging die, even a gap exists between the discharging die and a forming roller, normal production is not affected, and the function of adjusting the production thickness of aluminum alloy plates is also achieved; and through the arrangement of an oil spraying assembly, the situation that the production quality is affected due to the phenomenon of roll sticking on the surface of the forming roller is avoided, and the aluminum alloy plates can also be prevented frombeing corroded during later storage.

Description

technical field [0001] The invention relates to the technical field of clean production of aluminum alloys, in particular to a twin-roll casting and rolling device for clean production and deep processing of aluminum alloys. Background technique [0002] In the continuous casting and rolling production of aluminum and aluminum alloy slabs, the roll gap is an important process parameter, which determines the thickness of the cast slab. However, the roll gap cannot be adjusted arbitrarily since the birth of the twin-roll casting machine. During the rolling process, the installation position of the feeding nozzle and the size of the roll gap can only be adjusted slightly. Increasing the roll gap can increase the thickness of the plate, and at the same time, the gap between the roll nozzles will also increase. When the gap between the roll nozzles reaches a certain level and exceeds the surface tension limit of the aluminum liquid, aluminum water will flow out from the gap betwe...
