Abstract
The invention relates to a method for correcting a flue wall of a roasting furnace, which relates to the improvement of a process for roasting aluminum electrolytic pre-baked anode. The method is characterized in that the correction process is that supporting wooden sleepers are symmetrically arranged on a deformed position of a flue wall caused by the over-roasting of the roasting furnace, a hydraulic jack is arranged among between the supporting wooden sleepers, the wooden sleepers are pressurized through by the hydraulic jack, so that the deformed position of the flue wall is straightened and restored after being squeezed under the pressure effect of the wooden sleepers. The method for correcting the flue wall of the roasting furnace is characterized in that the hydraulic jack is adopted to apply the pressure, and the wooden sleepers are adopted to diffuse the pressure, so that the uniform pressure effect of the flue wall of the roasting furnace can be realized, no harm on to the flue wall exists, the correction effect is good, the repairing expense for the roasting furnace is reduced, the charge yield can be increased, and the production cost can be reduced. The method is suitable for the correction process under the situation that the deformation of the flue wall is not severe.
Description
Technical field
A kind of method of correcting baking furnace flame path wall relates to a kind of improvement of aluminum electrolysis prebake anode roasting firing technique.
Background technology
After present many roasters moved to 5 years, reach the maintenance time limit, part flue wall burn-off phenomenon is serious, cause flue wall distortion (being commonly called as " bulge "), even the part hopper can not normally take on the stove operation, the increasing of temperature control difficulty, affect shove charge output, cost raises, and repairs flue wall process complexity, and expense is high.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists for above-mentioned prior art, provides a kind of and can effectively correct flue wall and reduce the flue wall distortion, increases roaster service life, reduces the method for the rectification baking furnace flame path wall of maintenance cost.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of correcting baking furnace flame path wall, it is characterized in that its correcting process is to cause flue wall distortion place after the roaster burning, the symmetrical placement supported sleeper, between the support sleeper, the fluid pressure type jack is set, carrying out reinforcing by fluid pressure type jack pair sleeper exerts pressure, and then make flue wall distortion place be supported the sleeper pressure-acting, flue wall is squeezed straighten and restores.
A kind of method of correcting baking furnace flame path wall of the present invention is characterized in that flue wall is squeezed to straighten and after restoring, by fluid pressure type jack pair sleeper, flue wall distortion place applied pressure retention time be 6-8 hour.
A kind of method of correcting baking furnace flame path wall of the present invention, it is characterized in that its correcting process is that roaster hopper inside is filled first prebaked anode green body, flue wall to be filled to 1/3 place begins for the first time jack and exerts pressure, and the time of exerting pressure is 6 hours, the tamping inserts, then refill prebaked anode green body, flue wall to be filled to 2/3 place begins for the second time jack and exerts pressure, and the time of exerting pressure is 6 hours, the tamping inserts, continue to fill hopper, and with vacant 24 hours of this hopper both sides hopper.
A kind of method of correcting baking furnace flame path wall of the present invention, adopt the fluid pressure type jack to exert pressure, adopt sleeper to carry out diffusion pressure, reach the effect of evenly exerting pressure of correcting baking furnace flame path wall, be safe from harm for flue wall, rectification effect is good, has reduced the maintenance cost to roaster, increase shove charge output, reduced production cost.Be applicable to flue wall distortion and be not the correcting process in the very serious situation.
Description of drawings
Fig. 1 is the structural representation of the apparatus for correcting that uses of embodiment.
1 is baking furnace flame path wall among the figure, and 2 for supporting sleeper, and 3 is jack.
The specific embodiment
A kind of method of correcting baking furnace flame path wall, its correcting process is to cause flue wall distortion place after the roaster burning, the symmetrical placement supported sleeper, between the support sleeper, the fluid pressure type jack is set, carrying out reinforcing by fluid pressure type jack pair sleeper exerts pressure, and then make flue wall distortion place be supported the sleeper pressure-acting, flue wall is squeezed straighten and restores.Flue wall is squeezed and straightens and after restoring, by fluid pressure type jack pair sleeper, flue wall distortion place applied pressure retention time be 6-8 hour.
A kind of method of correcting baking furnace flame path wall, roaster hopper inside is filled first prebaked anode green body, flue wall to be filled to 1/3 place begins for the first time jack and exerts pressure, and the time of exerting pressure is 6 hours, the tamping inserts, then refill prebaked anode green body, flue wall to be filled to 2/3 place begins for the second time jack and exerts pressure, and the time of exerting pressure is 6 hours, the tamping inserts, continue to fill hopper, and with vacant 24 hours of this hopper both sides hopper.
Embodiment
A dark 5496mm of roaster, wide 710mm, the hopper of long 5298mm because flue wall 1 " burning ", causes distortion, and intermediate width becomes 650mm by the 710mm of design, makes the part kind can't shove charge.Use this technology that hopper is corrected, when producing the prebaked anode that 1513mm is long, 554mm is high, 670mm is wide, fill first the 1st layer of prebaked anode, prop sleeper and jack pair flue wall at flue wall 1750mm place and carry out the 1st rectification, after exerting pressure 6 hours, the hopper inserts is carried out tamping, shed jack, then refill the 2nd layer of prebaked anode, repeatedly correct again, wait to reach and correct when requiring, can finish this work.
Be noted that flue wall is can not be too damaged, refractory brick must have certain shock resistance, can not the flue wall phenomenon of caving in occur because correcting flue wall.Facts have proved that this measure is effectively, not only save the expense of maintenance flue wall, reduced cost, also prolonged the service life of roaster.
