Embodiment 1

[0032] A 5356 aluminum alloy rod continuous casting and rolling production system, comprising a melting system 1, a casting machine 2, a rolling pretreatment system 3, a rolling system 4, and a winding system 5 arranged in sequence; the rolling system 4 includes four Rough rolling mills 41 and eight finishing mills 42, four rough rolling mills 41 are arranged near the rolling pretreatment system 3 at the end far away from the eight finishing mills 42, and the end of the eight finishing mills 42 away from the four rough rolling mills 41 is close to the coiling system 5 settings; four rough rolling mills 41 and eight finishing mills 42 are provided with a number of rolls 43, and rolling grooves are arranged on the rolls 43, and the ellipticity of each rolling groove along the moving direction of the 5356 aluminum alloy rod decreases successively, and the adjacent The ellipticity of the rolling groove on the roll 43 of the winding system 5 is zero.

Embodiment 2

[0038] On the basis of the first embodiment, the diameters of the short sides of the rolling grooves of the rolls 43 on the four roughing mills 41 and the diameters of the short sides of the rolling grooves on the eight finishing mills 42 are both 9.5 mm.

[0039] During the rolling process, the diameter of the short side of the 5356 aluminum alloy rod is always 9.5mm, while the diameter of the long side of the 5356 aluminum alloy rod gradually decreases to ensure that the 5356 aluminum alloy rod can be gradually extended into a cylindrical shape, avoiding the 5356 aluminum alloy rod It is difficult to form when the diameter of the short side and the diameter of the long side of the rod are changed at the same time.

Embodiment 3

[0041] On the basis of Embodiment 1 or Embodiment 2, the casting machine 2 is a four-wheel horizontal casting machine, and the casting machine 2 includes a crystallization wheel, a steel belt, a pressing wheel, a tensioning wheel, a potting device, a cooling device, Spindle picker, approach bridge, oiling device.

[0042] The aluminum alloy liquid can be cast between the crystallization wheel and the steel belt of the four-wheel horizontal casting machine. After casting, the 5356 aluminum alloy rod can be rolled and formed, which is convenient for integrated production.

Abstract

The invention relates to the field of aluminum alloy rod production, in particular to a 5356 aluminum alloy rod continuous casting continuous rolling production system. According to the technical scheme, the 5356 aluminum alloy rod continuous casting continuous rolling production system comprises a smelting system, a casting machine, a rolling pre-processing system, a rolling system and a windingsystem which are sequentially arranged. The rolling system comprises four rough rolling mills and eight fine rolling mills. The ends, away from the eight fine rolling miss, of the four rough rolling miss are close to the rolling pre-processing system. The ends, away from the four rough rolling mills, of the eight fine rolling mills are close to the winding system. A plurality of rollers are arranged at the four rough rolling mills and the eight fine rolling mills. Rolling grooves are formed in the rollers. Ovality of the rolling grooves sequentially decreases in the moving direction of a 5356aluminum alloy rod. The ovality of the rolling groove of the roller next to the winding system is zero. The invention provides a continuous casting continuous rolling production system capable of producing the 5356 aluminum alloy rod and enabling the 5356 aluminum alloy rod to be with the good lattice structure.

Description

technical field [0001] The invention relates to the field of aluminum alloy rod production, in particular to a 5356 aluminum alloy rod continuous casting and rolling production system. Background technique [0002] 5356 aluminum alloy is an aluminum alloy filler metal containing up to 5% magnesium, which can be used for MIG or TIG welding and has good seawater corrosion resistance. [0003] There are two traditional production processes of aluminum alloy rods: vertical semi-continuous casting-extrusion method and horizontal continuous casting and continuous drawing. However, these two kinds of process equipment require large investment, many processes, large floor space, high tool and mold consumption and energy consumption, high geometric waste in the production process, and relatively low product yield. Especially the control of alloy composition, magnesium content and hydrogen content before and after continuous casting and continuous drawing, and the problem of easy wir...
