Suddenly：
It will be matched in smelting furnace by above-mentioned metal element content, melt temperature is 700 ~ 750 DEG C, and aluminium removes after melting through nitrogen charging
Gas, add coverture keep 20 minutes, and be stirred uniformly, skim；Aluminium liquid meets the requirements, and water conservancy diversion enters to stand furnace refining temperature
For 700 ~ 730 DEG C, refining agent still uses nitrogen, the liquid metals after refining, enters running gate system by chute（Preceding case,
Liquid surface height controlling mechanism, feed tip etc.）.Liquid metals acts on by static pressure itself, is shoved out from feed tip exit end face
Metal temperature be 685 ~ 700 DEG C, contacted with cooled rotary roller surface, the high-temp liquid metal into roll gap gap is anxious
Play is condensed into strand, also referred to as riser, and after stable riser, liquid metals constantly enters running gate system by chute, supplies
Expect the liquid metals flow sustainable supply rotary roller of mouth, band plate is gone out with regard to continuous casting and rolling, most laggard coiling machine rolls up cooling into blank
Application is rolled, blank volume is finally rolled down to required finished product thickness by cold-rolling mill, by annealing cut in rolls, then respectively enter
Performing check, packaging, storage.
Wherein, the working roll grinding roll shape convexity of the cold-rolling mill using upper roller it is convex, under roll out, roughness is 0.36 ±
0.02μm.Band longitudinal thickness during casting should be not more than 0.12mm, and the same plate difference of band is not more than 0.02 ~ 0.035mm, risen certainly
