Abstract
Description
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.
