AI Technical Summary

Technical Problem

The copper tapping bricks used in the existing copper rod continuous casting and rolling line vertical furnace are prone to breakage and peeling during use, have poor sealing performance, short service life, and are not easy to replace, resulting in low production efficiency, energy waste, and reduced structural strength of the vertical furnace.

Method used

A brick with an arc-shaped structure was designed, with a copper liquid channel and a slot inside. It is equipped with an elastic limiting component and a fire baffle assembly that can be quickly replaced. Precise positioning and convenient disassembly are achieved through inclined slides and limiting slots. It is integrally molded using silicon nitride and silicon carbide materials.

Benefits of technology

It improves the service life and production efficiency of copper tapping bricks, reduces energy consumption, ensures the stability and safety of the vertical furnace lining, and simplifies the maintenance process.
