AI Technical Summary

Technical Problem

The single-stage, single-acting plunger cylinder in the tilting mechanism of a traditional electric arc furnace lacks tension, resulting in insufficient safety during tilting. Furthermore, the sealing ring is prone to failure in high-temperature environments, posing a safety hazard. Additionally, installation is difficult, and leakage is likely to occur in areas with high water levels or heavy rainfall.

Method used

It adopts a design that combines a main tilting cylinder and an auxiliary tilting cylinder, uses a double-section double-acting cylinder to reduce the cylinder height, and is equipped with a telescopic dust cover and a water-cooled outer casing to improve safety and reliability.

Benefits of technology

This improves the safety and reliability of the tilting process, reduces the failure rate, avoids problems such as underground water seepage and sealing ring failure, and ensures the stability and safety of the electric arc furnace tilting.

Abstract

This utility model discloses a tilting mechanism for an electric arc furnace, including a tilting base, a tilting track set on the tilting base, and a tilting platform set on the tilting track. It also includes a control system, a main tilting cylinder, and an auxiliary tilting cylinder. The bottom end of the main tilting cylinder is hinged to the tilting base via a lower support, and its top end is hinged to the slag discharge side of the tilting platform via an upper support. The main tilting cylinder is a double-section, double-acting cylinder. The fixed end of the auxiliary tilting cylinder is hinged to the tilting track, and its telescopic end is connected to a support base at the bottom of the tilting platform. The support base is slidably set on the tilting track and moves along the tilting track under the action of the auxiliary tilting cylinder. This application ensures the safety of the tilting platform through the cooperation of the main tilting cylinder and the auxiliary tilting cylinder, and reduces the failure rate of the main tilting cylinder by setting a telescopic dust cover and a water-cooled outer casing.
