Embodiment 1

[0019] Combined with the accompanying drawings, the production of a low-magnesium aluminum alloy sheet strip casting and rolling coil with a specification size of 5.0×1000mm is illustrated as an example. The steps are:

[0020] 1 Batching and melting: First, weigh them separately according to the weight ratio, put them into the melting furnace until the ingredients are completely melted, melting temperature: 710°C.

[0021] 2 heat preservation: pour from the smelting furnace to the heat preservation furnace for heat preservation, the temperature of the heat preservation furnace is 730 ℃.

[0022] 3 Front box: Use siphon or quantitative pump to send the solution from the holding furnace into the front box. The discharge temperature of the front box is 710°C, and the front box is installed in conjunction with the distributor, and communicates through the diversion hole between them.

[0023] 4 Distributor: Through the diversion holes connected with the front box, through several...

Abstract

The invention discloses a continuous casting manufacturing method of low-Mg-Al alloy sheet belt, which comprises the following steps: allocating, fluxing, insulating, boxing, distributing, casting, coiling.

Description

Technical field: [0001] The invention relates to the technical field of nonferrous metal processing, in particular to a continuous casting and rolling processing method of low-magnesium aluminum alloy sheet strips. Background technique: [0002] Due to the advantages of strong corrosion resistance, excellent mechanical properties, high elongation, and high strength, low-magnesium aluminum alloy sheet strips are currently widely used in computer casings, pressure vessels, and structural plates in the fields of electronics and transportation. The production method generally adopts that the ingredients are melted into a low-magnesium alloy in a smelting furnace; the alloy melt is semi-continuously cast into a (flat) ingot; then milled and sawed; and then heated and hot-rolled into a coil. That is, batching and smelting → semi-continuous casting (ingot) → sawing → milling → heating → hot rolling → and other processes. The process is relatively long, the ingo...
