Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1, a kind of novel aluminum alloy casting and rolling machine lip, entirety is flat case shape structure, comprises melt inlet 9, left plate 5, right plate 7, base plate 8, by-passing parts and aluminium titanates composite bed 4.By-passing parts is wedge-shaped catch 6, wedge-shaped catch 6 is positioned at the import department of lip, and the width interval along lip is arranged, and symmetrical in the width direction centered by melt inlet, the gap of wedge-shaped catch 6 increases from middle part gradually to both sides, and the tip of wedge-shaped catch 6 upward.The width of wedge-shaped catch 6 is different, reduces gradually along the width of wedge-shaped catch 6 on lip width.The quantity of wedge-shaped catch 6 and size can adjust as required.Inside the outlet forward position of described lip upper slice and lip bottom sheet, place is provided with aluminium titanates composite bed 4.
Refer to Fig. 2 and Fig. 3, described aluminium titanates composite bed 4 is the novel high-quality refractory ceramic materials be composited through high temperature by commercial alumina, titanium dioxide and additive, there is extremely low thermal coefficient of expansion, moderate strength, there are extraordinary resistance to heat shocks and very high-melting-point, indeformable under high temperature, resistance to wear, stressedly do not fall slag and aluminium liquid is not infiltrated, there is processing rear surface smoothness, advantage that glacing flatness is higher.Paster is produced through special processing, and concrete operation step is as follows: produce metatitanic acid aluminium block material through batching, synthesis, high pressure, high temperature, produce paster through special processing, in appropriate location, finished product lip R arc place, adopts inorganic bonding agent that paster is carried out horizontal plane stickup.Dry 5 hours in the oven of 200 DEG C after pasting compacting, make it fully combine and the water in bonding agent is volatilized.Composite paster, as the outlet forward position of lip, need meet casting outer surface R radian and glacing flatness production requirement, and simultaneously processing flatness, smoothness have exceeded the requirement to alumina silicate.Finally carry out composite bed at lip forward position high-temperature resistant thermal insulating material, effectively ensure the heat-insulating property at forward position place.The lip that the utility model provides, completely solves the defect problem of longitudinal stripe under cast-rolled block surface and top layer.Cast-rolled block surface and inherent quality are significantly improved.This novel lip will bring profound influence to increasing substantially aluminium sheet strip and foil product quality.
