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.
