Aluminum bronze ingot mould ingot casting device

Abstract

The invention provides an aluminum bronze ingot mould ingot casting device and relates to the field of aluminum bronze casting. The aluminum bronze ingot mould ingot casting device comprises a furnacebody provided with an electromagnetic stirrer. An aluminum oxide capturer is arranged in an inner cavity of the furnace body. A magnet is inlaid in the inner wall of the furnace body. The aluminum oxide capturer comprises a barrel body fixedly installed on the bottom of the inner wall of the furnace body. A rotatable aluminum oxide collecting plate is arranged on the side wall of the barrel bodythrough a bearing. The interior of the aluminum oxide collecting plate is hollow. A filtering plate capable of sliding is arranged in the aluminum oxide collecting plate. Through holes are formed in the front face and the back face of the aluminum oxide collecting plate correspondingly. According to the aluminum bronze ingot mould ingot casting device, by arranging the aluminum oxide capturer, while an aluminum bronze solution is stirred in the furnace body, the aluminum oxide capturer captures aluminum oxide stirred along with the aluminum bronze solution in the furnace body, the captured aluminum oxide impurities are stored, and the situation that due to the aluminum oxide impurities existing in the aluminum bronze, the quality of the aluminum bronze is reduced is avoided.

Description

technical field [0001] The invention relates to the technical field of aluminum bronze casting, in particular to an aluminum bronze ingot mold ingot casting device. Background technique [0002] Aluminum bronze is a copper-based alloy with aluminum as the main alloying element. It is an aluminum bronze containing iron and manganese elements and belongs to high-strength heat-resistant bronze. In the traditional aluminum bronze ingot casting process, in order to remove the impurities in the aluminum bronze, it must be continuously stirred during smelting. At present, the aluminum bronze ingot casting process is mainly the horizontal continuous casting electromagnetic stirring process, and the continuous casting slab is passed through The electromagnetic force induced by the external electromagnetic field causes the unsolidified liquid aluminum bronze in the slab to stir and flow, thereby improving the solidification process and obtaining a good quality of the slab.

Problems solved by technology

[0003] However, in the process of aluminum bronze ingot casting, it contains a large amount of aluminum element, and the reaction between aluminum and oxygen in the air will produce hard alumina. The temperature in the traditional aluminum bronze electromagnetic stirring furnace can only reach about 1000 degrees Celsius, while the aluminum oxide The melting point is about 2100 degrees Celsius, so blocky solid alumina will be produced in the aluminum bronze electromagnetic stirring furnace, and the existing aluminum bronze electromagnetic stirring furnace cannot fully remove the blocky alumina, resulting in molten aluminum oxide in the aluminum bronze. The massive alumina on the body surface rolls to the inner wall of the crystallizer with the melt, and after cooling and hardening, it is easy to accumulate slagging, resulting in local discontinuity in the metal solidification process, thereby forming slag inclusions and reducing the quality of the ingot
