Problems solved by technology

Its disadvantages are: the casting nozzle of the casting rolling machine adopts a one-stage flow distribution method and the side of the diverter block is a straight line (the cross section of the upper part of the diverter block is triangular and the lower part is rectangular), which is prone to turbulent flow and leads to structural defects of the cast-rolled plate

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 , 2 As shown, a casting nozzle device includes: two upper and lower plates 3 oppositely arranged, an edge baffle 4 connecting the sides of the two upper and lower plates 3 , and connecting the two upper and lower plates 3 and two edge baffles 4 The bottom plate 5 of the bottom plate 5 is provided with a melt inlet 1 in the middle of the bottom plate 5, and the opposite side of the melt inlet 1 is a melt outlet 2, wherein the casting nozzle device also includes a first-stage splitter unit 6 and a Secondary split unit 7. The distance from the primary flow distribution unit 6 to the bottom plate 5 is greater than the distance from the secondary flow distribution unit 7 to the bottom plate 5 . The primary branching unit 6 includes several primary branching blocks 61 whose cross-sectional shapes are rectangular and arranged at inte...

Abstract

The invention provides a casting nozzle device which comprises an upper plate, a lower plate opposite to the upper plate, edge baffles connected with the side portions of the upper plate and the lower plate, and a bottom plate connected with the upper plate, the lower plate and the two edge baffles. A melt inlet is formed in the middle of the bottom plate, and a melt outlet is formed in the side opposite to the melt inlet. The casting nozzle device further comprises a first-level flow distributing unit and a second-level flow distributing unit which are sandwiched between the upper plate and the lower plate. Compared with the prior art, according to the casting nozzle device, the size of casting nozzle flow distributing runners is changed, two levels of flow distribution are adopted, and the shape and arrangement of flow distributing blocks are changed, so that the uniformity of molten aluminum metal in the casting nozzle device is improved, local cold points are reduced, and the cast finished product texture defects caused by slag bonding in inner cavities of casting nozzles are eliminated.

Description

【Technical field】 [0001] The invention relates to the field of casting, in particular to a nozzle device of a casting and rolling machine. 【Background technique】 [0002] The nozzle device plays the role of flow supply and flow diversion in casting and rolling production, and provides uniform flow field and temperature field for casting and rolling. In the related art, the Chinese patent publication No. CN103551534A discloses a "casting and rolling machine nozzle", which uses triangular diverter blocks for diversion, and the distance between the diverter blocks gradually increases from the middle to both ends. Its disadvantages are: the nozzle of the casting and rolling machine adopts a one-stage flow distribution method and the edge of the diverter block is a straight line (the cross section of the upper part of the diverter block is triangular and the lower part is rectangular), which is prone to turbulent flow and leads to structural defects of the cast-rolled plate.
