AI Technical Summary

Technical Problem

In the existing vertical casting method for preparing copper-aluminum composite materials, the copper plate is prone to displacement, resulting in uneven composite layer thickness and unstable conductivity. Furthermore, it is difficult to adjust process parameters in real time due to reliance on manual operation experience.

Method used

It adopts a double-layer clamping structure with fixed and floating clamping rollers with detection function, combined with angular velocity and pressure sensors to monitor the copper plate posture in real time, and uses the static pressure difference of molten aluminum to automatically return the copper plate to the center, so as to achieve dynamic clamping and precise position control.

Benefits of technology

It effectively solves the problems of "eccentricity" caused by copper plate misalignment and uneven aluminum layer thickness, improves the stability and conductivity of copper-aluminum composite materials, reduces reliance on manual operation experience, and ensures the reliability of the semi-continuous casting process.

Abstract

This invention discloses a method for producing copper-aluminum composite materials, comprising the following steps: preheating a pre-treated copper plate in a preheating furnace; using a hoist to lift the preheated copper plate and transfer it to a support platform inside the crystallizer; injecting argon gas to purge air and then pouring molten aluminum; when the initial solidified shell reaches a preset thickness, starting the ingot-feeding system for continuous pouring; when the ingot length approaches the target value, gradually reducing the flow rate of molten aluminum while appropriately reducing the downward movement speed of the support platform; this invention uses a double-layer clamping structure with fixed and floating clamping rollers for real-time detection of the copper plate's posture; the static pressure difference of the molten aluminum can be used to automatically straighten the tilted copper plate, effectively solving the problems of "eccentricity" and uneven aluminum layer thickness caused by easy copper plate displacement in traditional processes, reducing reliance on manual operating experience, making the semi-continuous casting process more stable and reliable, and providing high-quality billets for subsequent rolling processes.
