Abstract

A kind of construction method of furnace outer ring platform furnace shell welding surroundings in blast furnace construction, belongs to blast furnace technical field of construction.It is made of ring-shaped platform ontology, welding draught shield, ring-shaped platform lifting lug, ring-shaped platform powered lift system, five part of ring-shaped platform fixation.While the platform can effectively play radix saposhnikoviae outside furnace, safe and reliable operation platform is also provided for construction personnel.The platform can be reused up and down by lifting system.The advantage is that the safe and reliable space of operation platform is big, welding is set to continue to carry out, while having saved a large amount of construction cost.While radix saposhnikoviae can effectively be played outside furnace, safe and reliable operation platform is also provided for construction personnel.The platform can recycle round-trip use, until furnace shell erecting and welding is completed.

Description

The construction method of furnace outer ring platform furnace shell welding surroundings in blast furnace construction
Technical field
The invention belongs to blast furnace technical field of construction, in particular, provide a kind of furnace outer ring platform furnace in blast furnace construction The construction method of shell welding surroundings builds the installation and welding of last furnace shell ontology and installations and facilities suitable for blast furnace, especially suitable It is disliked together in coastal and weather conditions slightly regional.
Background technique
Blast furnace is the heart of entire ironmaking engineering, and last furnace shell welding is the core engineering of entire last furnace shell installation, furnace The welding quality of shell is to guarantee the premise of blast furnace service life, and furnace shell welding needs to carry out weld preheating, post weld heat treatment, It welds simultaneously and needs more people while carrying out, work once cannot stop halfway.Shoudu Iron and Steel Co capital Tang 5500m3The BF Design longevity Life 25 years, furnace shell are welded to form one by 25 band coaming plates, and material BB503, steel plate thickness is in 60mm~110mm, Shoudu Iron and Steel Co capital Tang 5500m3Blast furnace is located at prince wife Cao pasture industrial area, is coastal area, and construction climate condition influence is very big, thus must be properly Ground solves influence of the construction environment to furnace shell welding quality, and necessary welding surroundings safeguard measure is taken just to can guarantee that furnace shell welds Quality.
It in previous last furnace shell welding procedure, takes and makes and set up wooden springboard layer by layer, cause largely to construct Cost occurrence, construction personnel is on easy shelf, walking and construction, when welding, need to use colour bar layer of cloth not influence progress Layer is wrapped, and has to stop construction when wind is big, while colour bar cloth easily burns and causes security risk.
Summary of the invention
The object of the present invention is to provide a kind of constructions of furnace outer ring platform furnace shell welding surroundings in blast furnace construction Method solves the disadvantage that conventional construction method exists, according to the weather conditions of construction site and construction particularity, last furnace shell Welding procedure we use furnace outer ring platform come protect furnace shell weld working environment construction technology, the technology operation platform One-pass molding is applied repeatedly, the work such as achievable high furnace shell welding, weld inspection;The construction technology reforms previous traditional construction work Skill, the safe and reliable space of operation platform is big, influences welding surroundings protection in place, enables welding to continue to carry out, the same to time About a large amount of construction cost.The validity that ensure that welding surroundings enables furnace shell welding to continue, effectively carry out, The ring-shaped platform is safe and reliable in the construction process, convenient for the guarantee measure of construction, it is ensured that construction quality.
The present invention by ring-shaped platform ontology, welding draught shield, ring-shaped platform lifting lug, ring-shaped platform powered lift system, Five part of ring-shaped platform fixation is constituted.It is also construction personnel while the platform can effectively play radix saposhnikoviae outside furnace Provide safe and reliable operation platform.The platform can be reused up and down by lifting system.Specific step is as follows:
(1) ring-shaped platform ontology makes
According to furnace shell outer diameter, ring-shaped platform ontology construction drawing is drawn, makes ring-shaped platform ontology one according to construction drawing, ring Shape ontology is made of interior collar tie beam 1, cycle beam 2, attachment beam 3, Retractive leg 4, platform board 5.
(2) draught shield fabrication and installation are welded
Draught shield is made of vertical beam and baffle, and vertical beam 7 is welded on ring-shaped platform cycle beam 2, is then laid with a circle gear Aerofoil 8 just forms ring-shaped platform 9.
(3) ring-shaped platform lifting lug is installed
8 suspension centres, 8 promotion lifting lugs 6 of erecting and welding are uniformly arranged on ring-shaped platform ontology.
(4) ring-shaped platform powered lift system is arranged
8 electric blocks 10 are uniformly arranged, power Lifting Control System 11 is set.
(5) combination installation
Ring shaped movable platform 9 is mounted on furnace shell outer wall to be welded and is fixed temporarily first, secondly the electronic calabash of installation Ring-shaped platform is mounted under collar extension to be welded at 600mm by reed 10 and power Lifting Control System 11, and ring-shaped platform adjustment is steady It is fixed afterwards using Retractive leg 4 with furnace shell, springboard and asbestos cloth is laid with when the gap of furnace shell is greater than 100mm.
(6) it is recycled
In the furnace shell erecting and welding stage, the every installation 4-5 band of furnace shell is used as a cycle, after the completion of welding, then carries out next In a period, circulation is back and forth until furnace shell erecting and welding is completed.
The present invention evades the drawbacks of original conventional construction method, and furnace shell welds the method by using ring-shaped platform, to apply Worker person provides a safe and reliable operation platform, while solving the problems such as radix saposhnikoviae of welding, and furnace is effectively guaranteed Shell welding quality, improves construction efficiency, this method small investment, it is highly-safe, furnace shell welding quality is good the advantages that.
Detailed description of the invention
Fig. 1 is ring-shaped platform ontology schematic top plan view.Wherein, interior collar tie beam 1, cycle beam 2, attachment beam 3, Retractive leg 4, platform Plate 5.
Fig. 2 is ring-shaped platform schematic front view.Wherein, lifting lug 6, vertical beam 7, wind deflector 8, ring-shaped platform 9 are promoted.
