Technological process for continuous casting and rolling wrought magnesium alloy thin plate and band

Abstract

One kind of distortion magnesium alloy thin strap continuously cast roll over technique, its characteristic lies in: the stated continuously cast roll over technique, uses the ingredient and the melt system - > the divider - > continuously casts rolls over warm - > rolls over -> finishing -> the surface treatment -> product - > the production packing; uses the characteristic that the melt body under half solid condition forms and undergoes the rolling distorts, according to the solidification temperature scope of the different trademark alloy, hot melt and its the fluidity, in view of the product different width and the thickness request, designs the different divider, controls the magnesium alloy to coagulate - deformation range the 'character in', until the ingredient completely melts the raw material investment induction type smelting furnace; The magnesium alloy from the smelting furnace after the transportation fluid pumps into the divider, the magnesium alloy melt body to is stationed and between the disposition two rollers roller seams by the divider even subcrust current; Thus realize the metal from melts the body to the concrete distortion shape half / strip,directly to complete by a continuously working procedure.

Description

Technical field: [0001] The invention relates to the technical field of nonferrous metal processing, and relates to a process method for continuous casting and rolling of deformed magnesium alloy thin strips. Background technique: [0002] At present, in the process of processing deformed magnesium alloy sheets, the ingredients are melted into magnesium alloys in a melting furnace; the alloy melts are semi-continuously cast into slabs; Chemical annealing, heating, and hot rolling into slabs; then warm rolling / cold rolling into thin plates. That is, batching and smelting→semi-continuous casting (slab)→face milling→flaw detection→sawing→homogenizing annealing→heating→hot rolling→warm rolling / cold rolling→finishing→surface treatment→product packaging and storage . The process is long, the slab is difficult to plastically process at room temperature, and the yield is low. The yield of a 1.0mm magnesium alloy sheet is only about 20%. It also has the disadvantages of large energ...

AI Technical Summary

Problems solved by technology

The process is relatively long, the slab is difficult to plastically process at room temperature, and the yield is low. The yield of a 1.0mm magnesium alloy sheet is only about 20%. It also has the disadvantages of large energy consumption, high metal loss, and high cost.

And this method can only be produced in a single piece, and cannot be continuously rolled by the strip method like copper, aluminum, and steel, so the production efficiency is very low
