Equipment and method for solid-liquid vibratory casting and rolling of double-metal composite plate and strip

Abstract

The invention discloses a double metal composite plate strip solid-liquid vibration cast rolling device and method. The device mainly comprises a self-tensioning uncoiling mechanism, a coiling mechanism, a machine frame, a vibration system, a press-down side casting roller and a vibration side casting roller. The method mainly comprises the steps that a solid metal A strip blank is fed in through the self-tensioning uncoiling mechanism to be tightly attached to the face of the press-down side casting roller, metal B liquid is poured into the roller gap between the vibration side casting roller and the solid metal A strip blank, the surface of the solid metal A strip blank is coated with the metal B liquid, meanwhile, the vibration side casting roller is driven by a vibration system to vibrate, and solid-liquid cast rolling composite forming of a double metal composite plate is completed under the vibration condition. According to the double metal composite plate strip solid-liquid vibration cast rolling device and method, the vibration side casting roller is driven by the vibration system to vibrate, solid-liquid cast rolling composite forming of the double metal composite plate is completed under the vibration condition, vibration is beneficial to refining the metal melt solidification structure, dual-direction shear force can be applied to the composite interface, interface physical metallurgy bonding is promoted, and the interface bonding strength of the double metal composite plate is improved.

Description

technical field [0001] The invention relates to metal rolling, in particular to a solid-liquid vibration casting and rolling equipment and method for bimetallic clad plate and strip. Background technique [0002] With the development of modern science and technology, the requirements for the use of metal materials are no longer limited to a single mechanical property, but require metal materials to have comprehensive characteristics of both structure and function under multi-field or even extreme service conditions. Bimetal composite board is a layered composite material formed by compounding two metals with different physical and chemical properties through appropriate processes. By giving full play to their respective performance advantages, they can achieve comprehensive performance that cannot be achieved by a single metal board and save precious metals. Material. Composite materials with a variety of excellent properties can be prepared by selecting the properties of d...

Problems solved by technology

The explosive cladding method can only produce medium and thick plates, the plate shape is poor, it is difficult to level, and the production safety is insufficient; the composite strength of the solid-solid rolling composite process is limited, and diffusion heat treatment is required; the two-strand continuous casting method (liquid-liquid composite) It is easy to cause excessive growth and ablation of the interfacial layer, and the interfacial bonding strength of composite materials is poor and the size is limited

Although the above-mentioned process method has been perfected for many years, the obvious drawbacks cannot be solved fundamentally.
