With layer paving type refractory ceramic fibre structure, surface is using 0.5 mm of thickness~2mm stainless steel liner plate protection.Each oven chamber structure is substantially only
It is vertical, it is linked together by channel between furnace chamber, highly reaches 25m~30m, furnace insied width (headroom) is no more than 2.5m.Stainless steel lining
Plate matter is different according to furnace chamber temperature, mostly uses SUS304s or SUS310s.
When previous annealing furnace furnace lining stainless steel protection plate processing and fabricating, a kind of fixation hole (Φ 35mm) is only opened up, is installed
When according to number from top to down, sit in the right seat and carry out integral installation after, then carry out secondary adjustment, fixed and welding from top to down；
For annealing furnace furnace lining in long term high temperature use process, stainless steel protection plate will appear different degrees of deformation, and fire resisting is fine in furnace lining
Dimension may be exposed in burner hearth, and surface particles cause burner hearth pollution to influence strip surface quality after falling off.
Summary of the invention
Present invention seek to address that the above problem of the prior art, a kind of annealing furnace furnace lining is provided and is fixed with stainless steel protection plate
Method.The present invention reduces artificial wastes, shorten installation period, effectively control stainless steel protection plate orientation in long-term use process
Sliding reduces deformation, prevents in furnace lining fire resisting material particle to fall off and causes pollution in furnace and influence strip surface quality.
In order to solve the above-mentioned technical problem, a kind of annealing furnace furnace lining stainless steel protection plate fixing means, it includes
Step 1, analysis optimization drawing determine pre-stamped mode, size: according to chamber structure size, using temperature and not
The material of rust steel protection board, by calculating determining stainless steel pre-stamped mode and size in detail, and is recorded stainless steel one by one
In protection board part drawing；
Step 2 determines position of positioning hole: according to each furnace chamber furnace lining structure installation drawing of continuous annealing furnace, stainless steel being protected
Backplate mounting hole is by location hole 1, location hole 2 and fixed hole sort and identifies on corresponding part drawing；
Stainless steel protection plate processing and fabricating: step 3 is processed according to part drawing using the numerical control device precisely processed
Production, is numbered after confirmation, is layered by position and is packaged arrangement；
Step 4, surveying setting-out, anchor bolt welding: the first surveying setting-out on the inside of furnace shell marks in anchor studs " ten " word
Heart line, anchor bolt are welded using manual electric arc welding or stud welding machine；
Step 5, tapetum fibrosum are paved: tapetum fibrosum is successively paved by design sequence to the design number of plies and thickness；
Step 6, stainless steel protection plate installation: since first piece of upper left corner interior lining panel according to location hole 1 position and pacify
Then dress is laid with the second block protection plate according to location hole 2 to the right, successively until end；It presses after the completion of this layer of insert from upper past
It is successively installed down, tightened outer nut after protection board is all installed, checks that confirmation is errorless and uses argon arc solder joint
Weldering.
Annealing furnace furnace lining stainless steel protection plate fixing means, it includes hole that the step 6, which completes installation protection board,
The installation at hole position.
Accurate positioning, the easy to operate when present invention can ensure that the installation of stainless steel protection plate, avoids the repetition of secondary adjustment
Labour；Labor intensity of workers is reduced, is improved work efficiency, is shortened the construction period, remarkable in economical benefits.It is used for a long time in annealing furnace
In the process, the rigidity and sealing integrity for improving stainless steel protection plate can be effectively reduced because frequently stopping furnace and being grown
The deformation generated after phase high temperature action prevents in furnace lining fire resisting material particle to fall off and causes pollution in furnace and influence belt steel surface matter
Amount.
Specific embodiment
The present invention is according to furnace lining structure and to use temperature, it is first determined location hole mode, the arrangement of stainless steel protection plate
Position and pre-stamped mode size etc., then carry out processing and fabricating again；When installation using all round victory landing stage of scaffold from lower and
On accurately measure unwrapping wire, anchor bolt welding, then carry out from top to down ceramic fiber blanket successively pave, stainless steel protection plate
The mode successively installed, one-time-reach-place, safe and efficient high-quality completion furnace lining installation.
Construction procedure of the invention:
Analysis optimization drawing determines pre-stamped mode, size: protecting according to chamber structure size, using temperature and stainless steel
The material of backplate, by calculating determining stainless steel pre-stamped mode and size in detail, and one by one, stainless steel protection plate is arrived in reflection
In part drawing.
It determines position of positioning hole: according to each furnace chamber furnace lining structure installation drawing of continuous annealing furnace, stainless steel protection plate being pacified
Hole is filled by location hole 1, location hole 2 and fixed hole sort and is identified on corresponding part drawing.
Stainless steel protection plate processing and fabricating: processing and fabricating, core are carried out using the numerical control device precisely processed according to part drawing
To being numbered after errorless, it is layered to be packaged by position and arranges.
Surveying setting-out, anchor bolt welding: the first surveying setting-out on the inside of furnace shell marks anchor studs " ten " word center line, anchor
