Embodiment 1

[0022] Aluminum and its alloys

[0023] The coagulation roll (1) and the forming roll (2) are made of gun steel with good performance. In order to increase the cooling rate, aluminum oxide dispersion-strengthened copper can be used. The diameter of the roll is 600 mm, and there is a water-cooling tank inside. The linear speed of the roll rotation surface is 10-100 m / min, which is continuously adjustable, so that one machine can produce various types of aluminum and its alloy strips.

[0024] The feeding of integrated front box flow lip (4) is set on the side of the coagulation roller, the frame (7) is inclined 15° to the moving direction of the plate, and the molten metal is dragged by the coagulation roller (1) when it rotates; the thickness of the strip can be It is determined by adjusting the rotating speed of the roll, the heat conduction speed of the roll, the depth of the liquid in the flow lip (4), and the roll gap between the two rolls. The depth of the liquid metal a...

Abstract

The continuous metal sheet casting and rolling production apparatus consists of mainly solidifying roller, forming roller, asynchronous double roller driving mechanism, integral front box flow lip, liquid surface regulator and circulating water cooler. The present invention features that liquid metal is converted directly into sheet with homogeneous crystal grain structure in certain plastic deformation characteristic. The metal sheet has its solidification and formation completed separately in the position of the solidifying roller and the forming roller in different speed, which results in one increased kneading deformation to promote the formation of the sheet with plastic deformation structure characteristic. The present invention is suitable for production of metal sheet of different thickness and different kinds.

Description

Technical field: [0001] The invention belongs to a production equipment of thin metal plates and strips, in particular to a twin-roller continuous casting and rolling equipment used for the production of metal thin plates and strips of various thicknesses. Background technique: [0002] Sheet metal is the most widely used material for metal. Various machine parts, metal structural parts and equipment can be obtained by further processing the sheet metal with various metal processing techniques. Metal is supplied as an intermediate product in the form of sheet material, which greatly simplifies The production process of deep processing of metal materials reduces production costs and expands the application range of metal materials. [0003] The production of sheet metal is generally produced from ingots by hot rolling or cold rolling, and extrusion is also used for materials that are difficult to deform. The metal sheet produced through the above-mentioned method, especially...
