Abstract
The invention relates to an installation engineering technology of metallurgical equipment, and is a flip-over type installation method of a steel converter. The method is characterized by comprising the following installation steps: 1, building a converter installation bay, and mounting a track at the bottom inside the converter installation bay; 2, mounting a buggy ladle on the track; 3, building tailor-made inner and outer racks on the buggy ladle; 4, reversely hoisting a furnace shell of the converter on four inner upright posts of the inner and outer racks by adopting a travelling crane, and reversely hoisting a backing ring of the converter to six outer upright posts of the inner and outer racks; 5, slowly moving the buggy ladle to the installation position inside the converter installation bay; 6, welding a connecting device on the furnace shell and the backing ring into a whole, mounting left and right rotating shafts of the backing ring, a support seat and a transmission device; 7, dismantling the inner and outer racks, moving away the buggy ladle, and transferring the converter shell and the backing ring to right positions to install fire hole equipment. The converter can be installed under the absence of a large crane, can be subjected to sealed construction in a factory, and is short in construction cycle, and low in construction cost, and the quality and the safety are reliably ensured.
Description
Technical field
The present invention relates to the installation work technology of metallurgical equipment, especially a kind of flip-over type installation method of steel-making converter.
Background technology
In metallurgical engineering, be arranged on converter and install across interior converter, due to process technology limit, converter bay, without large bridge crane, cannot directly put the equipment hoisting such as converter shell, backing ring large single devices weight in place.
At present, domestic converter installation method mainly contains open type Method for Installation, and separate unit frame slippage formal dress is sent out.
1, open type Method for Installation: i.e. converter is installed across before construction of hydropower and just started the converter installation basis of constructing, and then lift converter, then the converter of constructing is installed across factory building.
Its shortcoming: converter installation is installed and belonged to critical circuits, and its installation period is long, the installing converter factory building of constructing again, total duration of engineering will extend, and also need to be in addition equipped with specially large-scale hoisting machinery.
2, separate unit frame slippage upright method of hull section construction: backing ring and furnace shell are all placed on same stand, and adopt fire door formal dress method upward.
Its shortcoming: this method also adopts stand slippage, do not need to be equipped with specially large scale hoisting machinery, save One-Shift Costs, but existing gantry designs is unreasonable, stand bearing load is large, and the material specification of making stand strengthens, the screw block specification needing is also large, and when formal dress the coupling device of backing ring and furnace shell is in overhead position, must erection construction scaffolding when welding, welding quality is also difficult for guaranteeing.
Summary of the invention
Object of the present invention will solve existing converter lift-on/lift-off system exactly needs large bridge crane, long in time limit, and separate unit frame slippage Method for Installation, gantry designs is unreasonable, manufacturing cost is high, and two kinds of methods all will adopt overhead welding operation, and welding quality is difficult for the problems such as assurance, and a kind of flip-over type installation method of steel-making converter is provided.
Concrete scheme of the present invention is: a kind of flip-over type installation method of steel-making converter, is characterized in that:
Comprise following installation steps:
The first step: building converter install across, installs across inner bottom part attachment rail in converter, track extends converter and installs across outside to driving operation;
Second step: buggy ladle is installed in orbit, according to the size of converter, can be used a buggy ladle or two buggy ladles are spliced;
The 3rd step: build special inside and outside stand on buggy ladle, it is uniform around big circumference that this stand has six roots of sensation outer column, there are four inner columns uniform around small circumference, large small circumference is concentric circumference, upper and lower two-layer union lever has been welded between adjacent two outer columns, upper and lower two-layer union lever has equally been welded between adjacent two inner columns, between each root inner column and adjacent two nearer outer columns, be welded hound and girt, and screw block is equipped with at least four outer columns and four inner column tops therein;
The 4th step: adopt driving that the furnace shell of converter is inverted to lifting to four inner columns of inside and outside stand, the backing ring of converter is inverted to lifting to the six roots of sensation outer column of inside and outside stand;
The 5th step: the screw block on the inside and outside stand of application is adjusted respectively the installed height mark of backing ring and furnace shell, is used windlass or the slow Mobile steel of chain block to hire a car to converter and installs across interior installation site;
The 6th step: by the coupling device on furnace shell and the backing ring one that is welded, the rotating shaft of backing ring left and right, supporting base and transmission mechanism are installed;
The 7th step: the inside and outside stand of dismounting, remove buggy ladle, converter shell, backing ring are gone to normotopia and carry out the installation of fire door equipment.
In the present invention, before Mobile steel hired car, on raceway surface, smear lubricating grease.
In the present invention, in described special inside and outside stand, at four outer column tops, four screw block are housed, four screw block become to be symmetrically arranged.
In the present invention, in described special inside and outside stand, outer column height is greater than inner column, the furnace shell end face that both difference of altitude are steel-making converter and the upper surface of backing ring poor.
The present invention has absorbed current domestic converter the advantage that generally adopts separate unit frame slippage field engineering has been installed, difference is to have adopted inside and outside combination stand, and converter adopts the method for upside-down mounting, make full use of the driving lifting in workshop, the adjustment screw block adopting is smaller, backing ring and furnace shell can be adjusted separately, and coupling device is in flat position, erection construction scaffolding in addition.Therefore, compared with prior art, more can guarantee welding quality, more reliable in safety, accelerate construction speed, reduce engineering cost, improve economic benefit.
