Abstract
The furnace bottom of annular heating furnace working lining construction method equipped with dilatation joint that the present invention relates to a kind of, construction method step are：(1), datum line is constructed；(2), strip groove mold is installed；Strip groove mold spaced radial is erected on the working lining castable face between inner ring beam and outer-ring beam；(3), work formable layer：Working lining castable mold is set up, working lining castable is using interval piecemeal cast；Form removal is carried out after all working layer castable is poured, furnace bottom of annular heating furnace work layer surface forms radially spaced strip groove, and strip groove is triangle, and the construction of furnace bottom of annular heating furnace working lining finishes.The furnace bottom that the present invention makes during heating steel billet will not roll tilt, heating steel billet is uniform, and billet oxidization will not be caused excessive, prevents iron scale from melting and corrodes furnace bottom working lining castable, extends the service life of furnace bottom, reduces maintenance number.
Description
Present patent application is that number of patent application is 201210575824.2, and patent name is furnace bottom of annular heating furnace work
Make layer construction method, the applying date is the divisional application of 2012.12.26.
Technical field
The invention belongs to rotary heating furnace field, especially a kind of furnace bottom of annular heating furnace working lining equipped with dilatation joint is applied
Work method.
Background technology
In metallurgy industry, rotary heating furnace is tube rolling station-service to heat the Thermal Equipment of circular steel blank, furnace bottom work
Layer castable generally pours into plane, and top is put into steel billet by pucellas, and furnace bottom rotation heats it.Furnace bottom was using
Cheng Zhong, exposure are gone wrong and are had：Due to the plane of furnace bottom and rotation after charging, steel billet is caused to roll, blank spacing is either large or small, makes
It heats uneven.Some steel billets mutually lean on, and pucellas may scratch adjacent steel billet when discharging, the quality of influence of rolled.Some steel
Base tilts, and pucellas can't clip when discharging, cause to continue to heat, hyperoxidation, and iron scale melts, and corrodes the cast of furnace bottom working lining
Material shortens the service life of furnace bottom, increases maintenance number, expands cost.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of furnace bottom of annular heating furnace equipped with dilatation joint
Working lining construction method, the construction method is simple and practicable, and steel blank can be effectively prevent to occur to roll phenomenon when furnace bottom rotates, right
Improve the heating quality of steel blank, and the service life of extension stove plays extraordinary facilitation.
The present invention solves its technical problem and is achieved through the following technical solutions：
A kind of furnace bottom of annular heating furnace working lining construction method equipped with dilatation joint, construction method step are：
(1), datum line is constructed：Input and output material center line is hung into survey on stove outer platform outside rotary heating furnace, waits for annular-heating
After furnace bottom sublevel between stove inner ring beam and outer-ring beam has been constructed, input and output material center line pilot measurement outside rotary heating furnace is added to annular
On hot stove furnace bottom sublevel, as the datum line of working lining on furnace bottom of annular heating furnace sublevel；
(2), strip groove mold is installed；Strip groove mold spaced radial is erected between inner ring beam and outer-ring beam
On working lining castable face；
(3), work formable layer：Working lining castable mold is set up, working lining castable is using interval piecemeal cast；Wait for institute
Form removal is carried out after having working lining castable to be poured, it is recessed that furnace bottom of annular heating furnace work layer surface forms radially spaced bar shaped
Slot, the construction of furnace bottom of annular heating furnace working lining finish.
The section of above-mentioned strip groove is triangle.
It is formed with dilatation joint between the working lining castable of above-mentioned furnace bottom of annular heating furnace working lining.
Above-mentioned strip groove mold is made using 2mm thickness iron sheets.
The advantages of the present invention are：
1, this furnace bottom of annular heating furnace working lining construction method equipped with dilatation joint is added after strip groove since furnace bottom turns
Dynamic synchronous with feeding device, steel billet can be accurately put into strip groove, and steel billet will not roll, and steel billet is put uniformly, heating
Uniformly, the requirement of rolling is met；And since steel billet is put uniformly and between steel billet there are gap, pucellas accurately will when discharging
Steel billet is clamped, and ensures rolling quality.
2, this furnace bottom for making of furnace bottom of annular heating furnace working lining construction method equipped with dilatation joint steel during heating
Base will not roll tilt, heating steel billet is uniform, and billet oxidization will not be caused excessive, prevent iron scale melt corrode furnace bottom work
Layer castable, extends the service life of furnace bottom, reduces maintenance number.
