Embodiment 1

[0034] Example 1: The rolling process of a three-layer composite aluminum plate in a factory: mainly for preparing ingot casting-welding and compounding-heating-hot rolling-cold rolling-finishing-packaging.

[0035] The specific process of hot rolling in the hot rolling stage of the three-layer composite plate is that the cleaned core layer and cladding layer are welded and compounded, and the compounded material can be rolled after being heated in a heating furnace. Combined with the actual production conditions of the factory, a two-roll reversing rolling mill with constant speed, same direction and equal diameter is used for reciprocating rolling. The diameter of the working roll is 500mm, the rolling speed is 1.5m / s, and the starting and finishing temperatures are 500°C respectively. , 400°C. The process parameters of the main rolling passes are shown in the table below:

Abstract

The invention provides a rolling method for improving the outer layer thickness distribution of a composite plate, which belongs to the technical field of metal plastic processing and molding. The rolling method is a new rolling method of the composite material, according to the metal deformation theory when rolling, each layer thickness equality of the cross section after rolled can be ensured when the equal deformation of metal at the inner and outer layers is ensured, namely, the deformation embedded into the internal of the rolling piece is ensured, simultaneously no serious single bulge occurs. The rolling method is mainly comprises the step of scheduling the entire rolling regulations, the core content is ensuring each pressed value is more than 30%, and ensuring the deformation of each layer is uniform in the transverse direction to achieve the purpose of improving the inner and outer layers thickness uniformity of the composite plate. The rolling method provided by the invention has universal adaptability to the rolling processing of the composite material, and is especially applicable to the processing of the symmetric composite materials.

Description

Technical field: [0001] The invention belongs to the technical field of metal plastic processing and forming, and in particular relates to a rolling method for improving the thickness distribution of inner and outer layers of a composite plate. Background technique: [0002] Composite material is a kind of multiphase solid material combined by two or more materials with different physical and chemical properties through composite process, and its performance is obviously better than that of raw materials. Metal composite material is a new type of material formed by combining two or more metals. Due to its advanced technology and technical characteristics of the material itself, the composite plate has incomparable advantages over a single metal material. [0003] Composite rolling is one of the most commonly used methods for producing composite materials. The production of hot-rolled composite aluminum sheets is a typical representative, mainly used as raw materials for air-...
