Description

Integral installation method for mammoth steel converter outer assemblage

Technical field

The present invention relates to the steel-making converter installation method, relate in particular to a kind of installation method of Large Furnace steel converter.

Background technology

Large-scale steel-making converter conventional mounting method is according to YJGF-94 " mammoth conveter body installation method ", adopts ladle chassis and special-purpose stand, utilizes hydraulic jacking device to install.Because ladle trolley is steel mill's plant-scale equipment, generally is reluctant to rent as erecting tools.The furnace shell of converter simultaneously all is the segmentation supply of material, and the building site weld seam is located at the backing ring position sometimes, just can't adopt aforesaid method.The external precedent that employing sliding method installing converter was once arranged.But they have done to take into full account when workshop building in design, install for converter to have changed the mast axis position, and the erecting device structure is set simultaneously, and furnace shell building site weld seam is not or not the backing ring place, so furnace shell and backing ring segmentation are installed.And this technology is the furnace shell assembling and is welded into whole back and backing ring assembling.Above-mentioned external method for the maintenance of steelmaking converter and the replacing of furnace shell, must re-start the change of factory building columns axial location and the erecting device structure is set, but this is impossible.The present invention is not only applicable to install, and is applicable to the maintenance of converter and the replacing of furnace shell.

Summary of the invention

Technical problem to be solved by this invention is that existing converter installation method installation period is long, and the cost height can not adapt to the furnace shell segmentation flexibly supply of material, the invention provides a kind of large-scale steel-making converter line and assembles integral installation method outward.Not only adapt to the various mode of supplly of furnace shell, do not relate to the factory building design simultaneously, do not increase construction investment, reduce installation cost greatly, reduce labor intensity, shorten installation period.Be applicable to installation and the maintenance engineering of converter.

Large-scale steelmaking converter line is assembled integral installation method outward, comprises that the assembling of assembling, tiling arrangement and backing ring of the assembly unit of assembling and the setting of positioning apparatus, furnace shell and welding, backing ring and furnace shell and integral installation are in place etc.Assembling and device in place comprise the hydraulic pressure pusher jack of saddle in place, slippage beam, column and supporting structure, usefulness in place.This installation method is carried out according to following step:

Step 1, the setting of assembling and device in place,

A., assembling slippage beam in place respectively is set in the both sides of stokehold platform converter medullary ray, and an end bearing of this slippage beam is on the platform crossbeam of stokehold, and the other end is supported on the trunnion of converter bearing spider, and described slippage beam below also is provided with the column of reinforcing the slippage beam;

B. on described slippage beam, measure and set with respect to the cross central line of trunnion of converter bearing block and longitudinal centre line and the relief of assembling ball socketed bearing seat location, make a mark, simultaneously corresponding ground survey assembling furnace shell in length and breadth to center line;

Step 2, in, epimere furnace shell assembling and welding

A. the ground under the corresponding slippage frame of converter assembling and erecting device according to survey the assembling furnace shell established in length and breadth to center line, set up furnace shell assembly platform and stand;

B. after the epimere furnace shell being transported into the building site, after the assembling of parts such as fire door and skimming plate,, be placed on the furnace shell assembly platform, and fire door down 180 ° of its upsets;

C. (be lower than weld seam 800mm) in the furnace shell commissure and set up the welding operation platform;

D. the hypomere furnace shell is hung on the epimere furnace shell of having assembled, carry out counterpart and adjust the counterpart gap;

E. go up, the welding of the furnace shell in stage casing;

Step 3, the backing ring assembling,

A. on converter assembling and the slippage beam installed, according to the centre of location line of surveying ball socketed bearing seat and saddle are set respectively, with crane the backing ring assembly are hung on the saddle of the ball socketed bearing seat of driving side and non-transmission side, and fix with bolt; The in length and breadth center line of while centering and adjustment diaxon bearing;

B., bearing pin and the bolt of self-adjusting bolt coupling device are installed at backing ring;

Step 4, the assembling of furnace shell and backing ring,

A. will be promoted in the backing ring by the backing ring central vertical at the furnace shell of backing ring bottom with the charging bay crane, and the self-regulated bolt is connected with furnace shell and firm nut;

B., upper bracket is installed and is adjusted its position and carry out then bolt-connection and welding;

Step 5, the assembling of tiling arrangement and ring trunnion;

With the reinforced crane of striding the tiling arrangement reductor is lifted and is assemblied on the gudgeon, tangential keys are installed then; Tiling arrangement is underslungly to be connected with horizontal torque arm by two vertical rods of tiling arrangement reduction case, and torque arm to be installation want on the basis.

Step 6, converter Integral in-position and installation,

A. in the end of two slippage beams of converter apparatus for assembling two jack and stop tab thereof are set respectively, jack pushing tow ball socketed bearing seat saddle is used on both sides simultaneously, with the converter Integral synchronous, slowly promote and slide onto on the bearing block;

B. centering and adjust bearing block;

C. the tiling arrangement reductor is connected with torque arm.

The step 6 converter is whole in place and install, and described screw block is 100t-200t (looking the converter size).Described torsion bar is to be fixed on the basis by wall screw.

From as seen upper, the assembling of integral installation method for mammoth steel converter outer assemblage of the present invention and the design of erecting device and setting do not relate to Architectural Design of Powerhouse, need not architectural design cooperation or requirement changes architectural design or increases erecting device etc., so do not increase capital expenditure, for numerous producers have found a cheaply converter installation and repair method.Because online outer assembling so the supply of material form of furnace shell is unrestricted, can be whole, the also in any form segmentation supply of material is to adapt to different means of transportation.Converter parts backing ring and ball socketed bearing seat, furnace shell etc. except that trunnion seat comprises that the tiling arrangement major parts all implements line and assemble outward, the one piece installation in position, therefore tiling arrangement need not be set stand is installed, do not establish dedicated trolley yet or use production ladle chassis, save installation costs, reduce labor intensity.
