Dynamic device, it is characterised in that Rolling Aluminium Plate comprises the following steps:
A) promote support by reclining drive device, and then change the corner dimension of the upper and lower roll line of centres and perpendicular bisector,
The midpoint of the adjustment upper and lower roll line of centres, to the length of lip, determines roll；
B) open off gas system, remove the gas in aluminum liquid；
C) case before the aluminum liquid after degasification enters after filtration system filtration, purification；
D) before being controlled by leveling device, the liquid level of aluminum liquid in case, measures the temperature of aluminum liquid, when aluminum liquid in good time
Temperature keeps a period of time after reaching setting value, when liquid level reaches suitable position, starts casting and rolling machine, controls upper and lower roll
Cooling water temperature；
E) adjusting the roll gap of upper and lower roll, then open lip, aluminum liquid is entered by lip and carries out casting in upper and lower roll gap,
Adjust roll casting speed in good time；
F) starting paint finishing, aluminium sheet roll entered after paint finishing carries out surface process, and startup cutter is not to
Qualified aluminium sheet is sheared, and the tension force finally controlling coiled sheet machine carries out coiled sheet to aluminium sheet.
By such scheme, step A) described in the angle of the upper and lower roll line of centres and perpendicular bisector be 15 °.
By such scheme, step D) described in before in case the temperature of aluminum liquid be 680～700 DEG C, the hydraulic pressure of cooling water is
0.20～0.50MPa, the temperature of cooling water is less than 35 DEG C, and the flow of cooling water is 100m3/h。
By such scheme, step E) described in aluminum liquid when being fine aluminium, roll casting speed is 900-1300mm/min, and aluminum liquid is for closing
Jin Shi, roll casting speed is 800～1100mm/min, and described roll gap is 5.5～8mm.
The invention has the beneficial effects as follows: a kind of method that tilting Aluminium Sheet Casts Rolling Mill Rolling Aluminium Plate is provided, rolling of inclination
Roller increases roll casting zone and makes the roll casting speed of casting and rolling machine improve 40%～50% can to produce aluminum manganese, the alloy and blunt of magnalium series
Aluminum, in production process, roll gap is adjustable, can obtain stable thickness of slab, adjusts roll casting speed, it is ensured that stablizing of casting is carried out.
Accompanying drawing explanation
Fig. 1 is the scattergram of one embodiment of the present of invention；
Wherein: 1, off gas system, 2, filtration system, 3, front case, 4, lip, 5, tilting casting and rolling machine body, 6, spray
System, 7, cutter, 8, coiled sheet machine.
Detailed description of the invention
For being more fully understood that the present invention, the invention will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of method of tilting Aluminium Sheet Casts Rolling Mill Rolling Aluminium Plate, tilting Aluminium Sheet Casts Rolling Mill includes that be sequentially arranged removes
Gas system 1, filtration system 2, front case 3, lip 4, tilting casting and rolling machine body 5, paint finishing 6, cutter 7 and coiled sheet machine 8 (as
Shown in Fig. 1), tilting casting and rolling machine includes roller, lower roll, support and reclining drive device, and Rolling Aluminium Plate comprises the following steps:
1) promote support by reclining drive device, and then change the corner dimension of the upper and lower roll line of centres and perpendicular bisector,
The midpoint of the adjustment upper and lower roll line of centres, to the length of lip, determines roll；
2) open off gas system, remove the gas in aluminum liquid；
3) case before the aluminum liquid after degasification enters after filtration system filtration, purification；
4) before being controlled by leveling device, the liquid level of aluminum liquid in case, measures the temperature of aluminum liquid, when aluminum liquid in good time
Temperature keeps a period of time after reaching setting value, when liquid level reaches suitable position, starts casting and rolling machine, controls upper and lower roll
Cooling water temperature；
5) adjusting the roll gap of upper and lower roll, then open lip, aluminum liquid is entered by lip and carries out casting in upper and lower roll gap,
Adjust roll casting speed in good time；
6) starting paint finishing, aluminium sheet roll entered after paint finishing carries out surface process, and startup cutter is not to
Qualified aluminium sheet is sheared, and the tension force finally controlling coiled sheet machine carries out coiled sheet to aluminium sheet.
It is 60～75mm that roll controls, and the length of roll casting zone is just to have determined that before casting starts, and it is by casting
Roll thickness of slab, roll diameter of roller and grinding convexity, alloy, capacity of equipment and lip lip thickness to determine.
The upper and lower roll line of centres is 15 ° with the angle of perpendicular bisector, uses 15 ° of angles to make aluminum liquid have one before entering roll gap
Gas effusion in the process flowed from bottom to top, beneficially aluminum liquid, in the operation of rolling, increases with the contact area of roll,
Be conducive to cooling and the condensation of aluminum liquid.
The hydraulic pressure of cooling water is 0.20～0.50MPa, and the temperature of cooling water is less than 35 DEG C, and the flow of cooling water is 100m3/
H, cooling water pressure is suitable, and in the case of flow is big, the heat that cooling water was taken away within the unit interval is more, it is to avoid roller shell occurs
Heat exhaustion, cracks and causes fracture.
In front case, the temperature of aluminum liquid is 680～700 DEG C, and before controlling, case temperature of liquid stablizes, it is simply that control roll casting zone liquid
Liquid metals temperature in cave keeps stable, is allowed to crystallization rate in strip casting process constant, it is ensured that stablizing of strip casting process.
When aluminum liquid is fine aluminium, roll casting speed is 900-1300mm/min, when aluminum liquid is alloy, roll casting speed be 800～
1100mm/min, described roll gap is 5.5～8mm, certain in Casting Rolled Sheet thickness, roll casting zone, front case liquid level, front case temperature
Under the conditions of, adjust roll casting speed and keep certain relation with setting rate, make the casting region in roll casting zone have certain with rolling zone
Proportionate relationship, to keep stable continuous casting and rolling to produce.
