AI Technical Summary

Technical Problem

The material of the traditional submerged arc furnace discharge pipe is cast steel or stainless steel. The magnetic conductivity makes it easy to melt and wear, with a short service life. It is also inconvenient to install and disassemble, and the sharp corners of the material are easily impacted and damaged, affecting production efficiency.

Method used

The feed pipe is made of insulating ceramic material, combined with a sealing structure and a protective sleeve, protected by high-temperature resistant insulating paint, and designed with a connecting sleeve of gradually varying diameter for easy and quick installation and disassembly.

Benefits of technology

The service life of the discharge pipe is extended, the installation and disassembly efficiency is improved, the sealing performance is enhanced, the damage caused by material impact is avoided, and the production efficiency is improved.

Abstract

The present invention provides a special arc-proof feed pipe for an electric arc furnace. The feed pipe is used to connect the feed port of the furnace body and the discharge pipe of the discharge bin. The feed pipe is a ceramic tube. The feed pipe is detachably arranged between the discharge pipe of the discharge bin and the feed port of the furnace body. A connecting sleeve for connecting to the discharge pipe of the discharge bin is provided on the upper outer side of the feed pipe. A sealing structure is provided between the connecting sleeve and the feed pipe. A flange connected to the top of the furnace body is integrally formed on the lower part of the feed pipe. The present invention replaces the traditional feed pipe with a new feed pipe with a longer service life and is easy to quickly disassemble and install. The feed pipe is effectively protected to prevent sharp corners of the material from directly impacting the feed pipe, thereby increasing the service life of the feed pipe, facilitating quick disassembly and assembly, and improving production efficiency.
