Abstract

A method for efficiently dismounting a furnace mouth of a converter comprises the steps: tiltingly rotating the converter to 180 degrees, so as to make the furnace mouth vertically downwards, then driving a converter bottom carrier to the underface of the converter, and lifting a top face of the converter bottom carrier until the top face is apart from the furnace mouth with a few centimeters; and then dismounting a fixing pin, allowing the furnace mouth to vertically fall on the top face of the converter bottom carrier, starting the converter bottom carrier, and carrying the waste furnace mouth away for treatment. The method has the advantages of simple operation method, safe and reliable working process, and high efficiency, and can be widely used as a method for dismounting the converter for a steelmaking plant.

Description

A kind of method of efficient dismounting converter mouth

Technical field:

The present invention relates to a kind of steelworks and tear the method for building converter open.

Background technology:

Steelworks, needs to remove old furnace lining with converter lining after the life-span, builds new furnace lining by laying bricks or stones.In the old furnace lining process of dismounting, need first dismantle fire door (water cooled steel structure), traditional method for dismounting is that fire door upwards, unloads tumbler pin, then vert body of heater to certain angle, hang up wireline, hang away with overhead traveling crane, the weak point of this kind of method for dismounting is that tilt angle is difficult for grasping, angle is low, a day coupler head reaches, and angle is large, the easy landing of fire door is hurted sb.'s feelings or smashes platform.Address this problem and become urgent need.

Summary of the invention:

Overcome the deficiencies in the prior art, propose a kind of method of easy to operate, safe and reliable efficient dismounting converter mouth.The method of efficient dismounting converter mouth is downward disassembly method, and converter tilting 180 is spent, and makes fire door vertically downward, then furnace-bottom vehicle is reached under converter, rises furnace-bottom vehicle end face, apart from fire door number centimeter; Then unload tumbler pin, fire door vertically drops on furnace-bottom vehicle end face, starts furnace-bottom vehicle, will discard fire door and transport processing.Working method of the present invention is simple, working process is safe and reliable, efficiency is high.

Accompanying drawing explanation:

Fig. 1 is working order view of the present invention.

Embodiment:

A most preferred embodiment of the present invention, as figure, by converter body 1 turnback of inclining, makes fire door 4 vertically downward, then furnace-bottom vehicle 3 is reached under converter, rises furnace-bottom vehicle end face 4, apart from fire door number centimeter.Then unload tumbler pin 5, fire door vertically drops on furnace-bottom vehicle end face.Start furnace-bottom vehicle, will discard fire door and transport processing.

Claims (1)

1. a method for efficient dismounting converter mouth, is characterized in that: converter tilting 180 is spent, make fire door vertically downward, furnace-bottom vehicle is reached under converter, rise furnace-bottom vehicle end face, apart from fire door number centimeter; Unload tumbler pin, fire door vertically drops on furnace-bottom vehicle end face, starts furnace-bottom vehicle, will discard fire door and transport processing.
