A kind of magnesium alloy thick plate continuous production equipment and process

Abstract

The invention discloses a magnesium alloy thick plate continuous production device and technology. The device includes a middle buffering ladle, a magnesium alloy refining solution feeding pipeline and a first argon conveying pipeline are connected above the middle buffering ladle, a casting pipeline is connected below the middle buffering ladle, an outlet of the casting pipeline penetrates through a crystallizer cover and stretches into an inner cavity of a constant temperature controlling segment of a crystallizer, a plate belt surface anti-corrosion protection segment below a solidification segment of the crystallizer is connected with guiding rollers which are closely arranged, a plate blank cutting and separating device for cast blanks and a cast blank transferring mechanism are arranged below the guiding rollers which are closely arranged, a cutting and collecting device is arranged on the lower portion of the cast blank transferring mechanism, and the cutting and collecting device is connected to a cutting and concentration conveying device. According to the technology, magnesium alloy liquid is transported into the closed combined crystallizer through the pipeline and solidifies while moving downwards, the solidified surface is subjected to anti-corrosion treatment, the magnesium alloy thick plate blanks are continuously pulled out through a supporting and pulling roller, the plate with certain length and width larger than 50 mm is formed through subsequent cutting and separating, and the production efficiency of the magnesium alloy thick plate blanks is improved.

Description

technical field [0001] The invention relates to the field of continuous casting of magnesium alloy thick plates in the metallurgical industry, in particular to a continuous production equipment and process for magnesium alloy thick plates. Background technique [0002] At present, magnesium alloy slabs are cast by semi-continuous or die casting methods at home and abroad. Compared with die casting, semi-continuous casting technology has improved efficiency, but semi-continuous casting cannot be continuously produced. It is based on aluminum alloy semi-continuous casting technology. The derived technology is to inject the magnesium alloy melt into the closed ingot mold. The height of the ingot mold is generally between 110 and 250mm. The dummy tray blocked under the mold supports the magnesium alloy billet and moves down slowly, the speed of moving down is generally below 0.15m / min, after moving down to a certain length, stop injecting the melt into the mold, and remove the m...

AI Technical Summary

Problems solved by technology

The height of the casting mold is small, and the cooling rate of the magnesium alloy molten liquid in the casting mold is limited, which restricts the improvement of the casting speed, which in turn affects the improvement of the efficiency of the magnesium alloy billet.
