Integrated diversion board crystallizer for casting aluminium alloy

Abstract

The invention relates to an integrated diversion board crystallizer for casting aluminium alloy, an upper cover plate is connected on a crystallizer body, an inner cavity of which is internally provided with an integrated diversion board; the integrated diversion board is vertically connected with the inner wall of the inner cavity of the crystallizer body; a rubber strip is used for sealing the integrated diversion board and the bottom surface of the inner cavity of the crystallizer body; the inner cavity of the crystallizer body is divided into an outer water cavity and an inner water cavity; the integrated diversion board is evenly distributed with diversion holes used for leading the outer water cavity to be communicated with the inner water cavity; and the inner wall of the crystallizer body is provided with a water spray hole which is communicated with the inner water cavity. The integrated diversion board crystallizer leads the diversion board and the crystallizer body to be in an integrated design, has the function of evenly distributing cold water, solves the problem that the diversion board is easily deformed and difficult to assemble, and is beneficial to improving the cast ingot quality and increasing the finished product ratio of cast ingots.

Description

technical field [0001] The invention relates to an integrated water-separating plate crystallizer for aluminum alloy casting, which belongs to the technical field of aluminum alloy semi-continuous casting equipment. Background technique [0002] In the production process of aluminum alloy semi-continuous casting, most of the heat released by the solidification of molten aluminum in the crystallizer is taken away by the cooling water. The cooling water with uniform water outlet and stable flow rate can ensure the uniformity and stability of the primary shell in the mold Growth. Guarantee the uniform cooling of the slab, and reduce the defects of the slab caused by the uneven thickness of the primary slab shell or the uneven stress caused by the uneven temperature of the ingot. Therefore, a reasonable semi-continuous casting crystallizer water chamber structure is of decisive significance for improving the quality of ingots and increasing the yield of ingots.

Problems solved by technology

But this kind of water divider has two disadvantages: First, it needs to process the water divider separately, and make grooves on the upper cover and the lower cover of the crystallizer, which increases the difficulty of mold processing, and also increases the mold and water divider. Difficulty in matching the plates; secondly, the water diversion plate and the crystallizer body are not a whole, especially the water diversion plate made of IBS resin material is easily deformed by the impact of cooling water for a long time, which weakens the diversion effect
