Emergency repair device and method of heating furnace side wall

Abstract

The invention discloses an emergency repair device and method of a heating furnace side wall. The device and the method are mainly designed for solving the problem of inward inclination of the heating furnace side wall. The device comprises a plurality of supporting walls for supporting the heating furnace side wall. All the supporting walls are arranged on a rooting foundation wall at the bottom of a heating furnace at preset intervals. The side faces, in the vertical direction, of the supporting walls are in contact with the heating furnace side wall. The emergency repair device is simple in structure, low in manufacturing cost and short in construction time, the heating furnace side wall inclining inwards can be supported and protected by arranging the supporting walls, the requirement for conducting emergency repair on the heating furnace side wall within the short shutdown time can be met, and the requirement of the heating furnace side wall for emergency repair is effectively met.

Description

technical field [0001] The invention belongs to the field of industrial furnaces, and in particular relates to an emergency repair device and method for a side wall of a heating furnace. Background technique [0002] In the field of industrial furnaces and kilns, especially the side walls of steel rolling heating furnaces are usually formed by ramming and pouring refractory castables in sections after hanging anchors on the furnace skin steel plates. Steel rolling heating furnaces, especially large walking beam heating furnaces, are usually divided into upper and lower furnace walls for block casting due to the high furnace height. The side wall anchors are usually machine-made anchor bricks, and most of the force is borne by the anchor bricks. Since the steel rolling heating furnace is usually operated continuously for a long time and under heavy load during production, and the anchor bricks are prone to aging, deformation and fracture under long-term vibration and high te...

AI Technical Summary

Problems solved by technology

Due to the continuous operation of the steel rolling heating furnace for a long time and heavy load during production, and the anchor bricks are prone to aging, deformation and fracture under long-term vibration and high temperature conditions, sometimes causing the side wall to tilt inward, which seriously threatens the safety of production and operation

Since the steel rolling heating furnace is the key equipment of the steel rolling production line, its shutdown node and time are strictly planned, and due to the high temperature and high pressure characteristics of the equipment itself, it is difficult to carry out large-scale maintenance and replacement during short-term shutdown

[0003] Due to the large workload of demolition and masonry of the furnace wall; the anchor brick is a special-shaped structure, and the production cycle is long; if the furnace shutdown time is too long, it will seriously affect the production and operation of the entire rolling line, resulting in large economic losses

If problems such as inclination of the side wall are found during the inspection of the short-term shutdown, usually only some emergency measures can be taken, and major maintenance and construction will be carried out after the planned overhaul time
