Compact light alloy asynchronous casting and rolling forming machine

Abstract

The invention relates to a compact light alloy asynchronous casting and rolling forming machine which is suitable for high-temperature casting and rolling forming of light alloy plates and strips. Themachine mainly comprises a frame base, a left frame, a right frame, a feeding device, a main casting roller, an auxiliary casting roller, a bearing pedestal, a gearbox, a drive motor, a supporting frame, sliding guide rails, a discharge correction device and a roll gap adjustment device, wherein the feeding device can be moved on the guide rails, and can realize multiple ways of feeding, so as toachieve pouring at different positions, and the size of a pouring gate can be adjusted according to needs, thereby obtaining metal sheets of different specifications; the main casting roller and theauxiliary casting roller can be separately and independently driven, thus achieving asynchronous casting and rolling forming; and the discharge correction device can correct and change the discharge direction, and can realize continuous forming of long casting and rolling plates. The forming machine has a compact and simple structure, is convenient to operate, and high in energy utilization rate and production efficiency, can realize automation, and is an efficient and low-cost light alloy casting and rolling forming device.

Description

technical field [0001] The invention relates to the technical field of cast-roll forming of light alloys, which can realize synchronous or asynchronous cast-roll forming of light alloys, and is especially suitable for low-cost and short-flow cast-roll forming of light alloys. Background technique [0002] With the rapid development of the machinery manufacturing industry, the demand for profiles at home and abroad is increasing day by day. Compared with hot rolling, cast rolling has the advantages of low cost, short process, low energy consumption, etc., and has great development potential. The basic principle of casting-rolling technology is to inject molten metal liquid directly between two relatively rotating casting-rolling gaps, and the casting-rolling rolls undertake the functions of crystallization and rolling at the same time, which can realize short-process continuous production of plates and strips. [0003] The casting and rolling machine commonly used at present...

AI Technical Summary

Problems solved by technology

[0003] The casting and rolling machine commonly used at present occupies a large area, and the casting and rolling speed is relatively slow. It is difficult to realize semi-solid rolling, which affects production efficiency.

When the solidification range of the alloy is narrow, it is easy to cause clogging of the nozzle, resulting in failure of casting and rolling

In addition, when producing alloy sheets and strips with high alloy content in industry, there are many types and high content of alloying elements added, which is prone to severe macro-segregation and micro-segregation.

Invention patent CN 107321942 A proposes an aluminum alloy vertical casting and rolling process and device, which reduces segregation by reducing the temperature of the center of the molten pool, but is not suitable for the preparation of active metal profiles such as magnesium alloys
