Embodiment Construction

[0022] As shown in Figure 1, the continuous lubricating crystallizer for aluminum alloy semi-continuous casting includes a crystallizer body 8, an upper cover 5 and a lower cover 11; the inner wall of the crystallizer is inlaid with a graphite lining 4, and an independent The oil chamber 3 and the graphite lining 4 have a vertical symmetrical structure with a taper, and the taper angle ranges from 174° to 179°; the crystallizer body 8 is equipped with two independent water chambers, namely the upper water chamber 1 and the lower water chamber 2. An independent water inlet 71 is opened on the upper water chamber 1, and an independent water inlet 72 is opened on the lower water chamber 2. A water retaining plate 61 is installed in the upper water chamber 1, and a water retaining plate 62 is installed in the lower water chamber 2. A row of water spray holes 9 is set at the bottom of the upper water chamber 1, and the angle range of the water spray holes 9 is 15° to 35°. A row of w...

Abstract

The invention relates to a continuous lubrication crystallizer used for casting aluminum alloy semi-continuously, wherein the inner wall of the crystallizer is inlaid with a graphite lining, a top cover of the crystallizer is internally provided with an independent oil cavity, the graphite lining presents up-down symmetric construction with a taper, a body of the crystallizer is provided with a top water cavity and a lower cavity which are independent, the top water cavity and the lower cavity are respectively opened with an independent water inlet and are respectively provided with a splash plate, the bottom of the top water cavity is provided with a row of water passing ports, the bottom of the lower water cavity is also provided with a row of water passing ports, the angel of the water passing ports of the top water cavity is different from and presents interlaced shape with the water passing ports of the lower water cavity's, when casting, a layer of continuous oil film forms via infiltrating oil forming the oil cavity to the graphite lining, which has effects of heatproof, reducing once cooling of ingot casting at the same time when improving graphite lubricating oil effects, two independent water cavities realize the independent or double water-cavity water supply, which improves the aftercooling effect on the premise of ensuring heat cracks not to appear at the early stage of aluminum alloy ingot casting, thereby realizing a low liquid level on the inner portion of the crystallizer, and distinctively improving surface quality of the ingot casting.

Description

technical field [0001] The invention relates to a crystallizer for semi-continuous casting of aluminum alloys, in particular to a lubricable crystallizer for semi-continuous casting of aluminum alloys, and belongs to the technical field of semi-continuous casting of aluminum alloys. Background technique [0002] During the semi-continuous casting process of aluminum alloy, the heat transfer of the side wall of the mold has an important influence on the surface quality of the aluminum alloy billet. In the traditional semi-continuous casting process, the crystallizer is usually made of copper alloy. During the casting process, the copper inner wall is in direct contact with the liquid aluminum alloy melt, and the casting resistance is large. Usually, smooth casting is achieved by manually applying lubricating oil. Therefore, the surface quality of the ingot is poor, and a large amount of turning is required to meet the requirements of subsequent thermal deformation. At presen...
