AI Technical Summary

Technical Problem

In traditional solid-liquid casting and rolling composite technology, there are problems such as low preparation and treatment efficiency of solid metal plate and strip, difficult to control the temperature gradient, uneven flow of liquid metal and unstable composite interface quality, especially when the melting point of the liquid clad metal and the solid metal plate and strip are close to each other, it is difficult to form stably.

Method used

The multi-layer heat transfer composite plate and strip grading casting and rolling composite method is adopted. Through a modular integrated design, each layer of the flowing device is laminated, so that the metal materials of different components are completely melted and flow into the graded step gradient buffer flow channel, adjust the casting speed and temperature to achieve uniform flow and temperature gradient control of liquid metal in the casting and rolling area, reduce the preparation process of solid metal plate and strip, and improve the fluidity and composite interface bonding strength.

Benefits of technology

Significantly shortens the process flow, improves production efficiency, ensures the uniform flow of liquid metal in the liquid space, achieves high-strength metallurgy combination, avoids secondary melting of solid metal plates, and meets the material performance of different application needs, which is suitable for the upgrading and transformation of existing equipment.

Abstract

The invention belongs to the technical field of cast-rolling forming, and relates to a multi-layer heat transfer composite plate strip graded cast-rolling composite method and equipment, in the cast-rolling process, the temperature gradient regulation and control of a composite interface in the in-situ different-temperature cast-rolling composite process are realized by controlling the pouring temperature and the pouring speed of each component metal, and the secondary melting phenomenon of a solid plate is avoided; all layers of the flow distributor are arranged in a laminated mode, different component metal materials are completely melted into liquid metal, then the liquid metal flows into a liquid flowing space in the flow distributor and then flows into a cast-rolling area to be subjected to cast-rolling compositing, in the whole process, the procedures of solid metal plate strip preparation, surface treatment and the like in a traditional solid-liquid cast-rolling compositing technology are omitted, the technological process is shortened, and the production efficiency is improved. And meanwhile, a stop block with an inclined angle and a multi-stage flow dividing block are arranged in the liquid flowing space, flowing-in liquid metal is subjected to buffer contact, the flow direction is changed, flow dividing is conducted, the fluidity of the liquid metal in the liquid flowing space is improved, and the problem that outflow in the width direction of the side flow distribution plate is not uniform is solved.
