AI Technical Summary

Technical Problem

In the semi-continuous casting process of thick-walled aluminum tubes, the inner wall of the aluminum tube tends to stick to the mandrel when cooling, which can lead to discontinuous casting or even equipment damage. Existing methods have poor applicability.

Method used

Design a semi-continuous aluminum tube casting device with intelligent core removal, including a frame, traction system, crystallizer vibration system, core mold vibration system, chute unit and load-bearing plate. By combining the vibration systems of the crystallizer and core mold with feedback control from mechanical sensors, the aluminum tube is prevented from sticking to the core mold.

Benefits of technology

It enables continuous casting of aluminum tubes, reduces equipment accidents, and improves the surface quality and grain refinement of aluminum tubes. In particular, it reduces the formation of surface segregation nodules for tube blanks with a small inner-outer diameter ratio.

Abstract

The application discloses an aluminum pipe semi-continuous casting device with intelligent core stripping and a method, and relates to the technical field of light alloy casting. The device comprises a rack, a traction system for pulling an aluminum pipe blank, a crystallizer vibration system, a core mold vibration system, a chute unit for preheating a flow guide molten metal, a bearing plate, a bearing base, and a feedback control system for the vibration of the crystallizer and the core mold. The device adds the functions of the vibration of the crystallizer and the core rod and the mechanical sensor feedback control function on the basis of the conventional semi-continuous casting device. The crystallizer and the core rod are vibrated through the mechanical sensor feedback control to avoid core holding and efficiently strip the core, thereby ensuring the continuous casting. The device solves the problem that the aluminum pipe is difficult to strip the core from the core mold during the semi-continuous casting process, ensures the continuity of the casting, reduces the occurrence of casting accidents, and improves the production efficiency of the aluminum pipe casting.
