Abstract
The invention discloses the discrepancy in elevation laying fireproof bricks method of the new and old cylinder docking of a kind of cement rotary kiln, it is characterized in that, including: new cylinder of polishing, detection, pre-mould, ash is flat, build by laying bricks or stones and the step such as fine setting completes, this building method ensures new and old cylinder refractory brick entirety modulus, make refractory brick overall effectively operation in Dayao runs, reduce during refractory brick runs crowded broken, make Dayao run and operate on same centrage with refractory brick friction, and every piece of laying fireproof bricks adopts wet block and every block of refractory brick to beat, make big effective docile of refractory brick in kiln cylinder body, making refractory brick on new and old cylinder is all full sized brick modulus, guarantee new, the globality of refractory brick on old cylinder.In rotary kiln running process, refractory brick sliding friction removes the obstacle that new and old cylinder occurs that the discrepancy in elevation is brought, and decreases the number of times stopping kiln because of laying fireproof bricks quality, extends refractory brick life cycle.
Description
Technical field
The present invention relates to cement rotary kiln to put up a kiln field, especially relate to the discrepancy in elevation laying fireproof bricks method of the new and old cylinder docking of cement rotary kiln.
Background technology
At present, along with the rotary kiln operating time limit is more and more longer, there is interim replacing also with increasing in kiln cylinder body, but when kiln cylinder body is changed owing to old kiln cylinder body has abrasion, and the kiln cylinder body newly changed does not wear and tear, so when changing kiln cylinder body, arising that new and old kiln cylinder body has certain discrepancy in elevation, bring to laying fireproof bricks and very big build risk by laying bricks or stones, also give refractory brick in Dayao runs refractory brick friction and squeezed broken.In order to ensure rotary kiln laying fireproof bricks quality; guarantee rotary kiln refractory brick stable operation; the position laying fireproof bricks changing kiln cylinder body is carried out technological invention; ensure rotary kiln laying fireproof bricks quality and decreased rotary kiln and stop kiln repair rate; fill up domestic blank for refractory material construction industry abnormal position laying fireproof bricks in kiln, also compensate for the construction method that the current rotary kiln cylinder discrepancy in elevation of China is built by laying bricks or stones.
Summary of the invention
It is an object of the invention to provide the discrepancy in elevation laying fireproof bricks method of a kind of cement rotary kiln new and old cylinder docking, solve the discrepancy in elevation that the new and old kiln cylinder body of cement rotary kiln combines, reduce laying fireproof bricks and bring and very big build risk by laying bricks or stones.
The technical solution adopted for the present invention to solve the technical problems is:
The discrepancy in elevation laying fireproof bricks method of the new and old cylinder docking of cement rotary kiln, it is characterised in that: comprise the following steps,
1) first have to carry out actually detected to the new and old cylinder discrepancy in elevation, according to measured data, new and old cylinder altitude distance scale cun is analyzed；
2) the cylinder seam kiln cylinder body weld more finished changing is polished, to reduce unfitness of butt joint, meet laying fireproof bricks requirement；
3) hoop line 2 road is put for standard to cylinder new, old with new cylinder weld seam, at cylinder new, old, 198-200mm hoop line is set from seam, cylinder at rear portion carries out discrepancy in elevation process, and set up one ring processing brick guarantee laying fireproof bricks modulus, the gap clearance of laying fireproof bricks mould is less than the gap clearance 50mm of standard brick；
4) carrying out filling out ash according to the cylinder discrepancy in elevation, laying fireproof bricks superelevation cylinder should control at 0-50mm to low cylinder extension；
5) by through for hoop line on brick-laying machine, form 360 degree of circumference, calculate processing brick size according to loop wire, discrepancy in elevation place is filled with chamotte levelling, brick-laying machine is processed the wet block of brick；
6) in new cylinder building process, hoop seam is carried out appropriate amount of fine-tuning, the replacing cylinder seam in kiln tail direction is if any the discrepancy in elevation, building method is ditto processed brick masonry, as excessive in last ring of new cylinder super drop of new refractory brick, process a ring before, be processed brick masonry with old refractory brick interface according to actual hoop size simultaneously.
Beneficial effect: the present invention makes refractory brick on new and old cylinder be full sized brick modulus, it is ensured that the globality of refractory brick on cylinder new, old.In rotary kiln running process, refractory brick sliding friction removes the obstacle that new and old cylinder occurs that the discrepancy in elevation is brought, decrease the number of times stopping kiln because of laying fireproof bricks quality, extend refractory brick life cycle, reduce production cost, improve production economy benefit for cement company, solve a domestic cylinder of rotary kiln discrepancy in elevation position laying fireproof bricks difficult problem, filled up domestic blank.
Detailed description of the invention
Embodiment 1,
The discrepancy in elevation laying fireproof bricks method of the new and old cylinder docking of a kind of cement rotary kiln, comprises the following steps:
The first step: the cylinder seam kiln cylinder body weld more finished changing is polished；
Second step: putting hoop line 2 road for standard to new and old cylinder with new cylinder weld seam, cylinder seam hoop line traffic control new, old is at 198-200mm.
3rd step: carry out filling out ash according to the cylinder discrepancy in elevation, with kilneye direction, then builds new cylinder the first ring brick.
First build, after fill out the new and old cylinder discrepancy in elevation ash.High-order cylinder laying fireproof bricks should control at 0-50mm beyond low shell portion.
4th step: put loop wire through hoop line on brick-laying machine and carry out through building processing brick by laying bricks or stones,
5th step: measure processing brick size according to loop wire, be processed brick masonry on brick-laying machine, it is necessary to be processed at the forward and backward second ring brick of weld seam, it is ensured that be full sized brick before and after weld seam,
6th step: the wet block of processing brick builds processing brick by laying bricks or stones on brick-laying machine, but must wet block and every piece knock,
7th step: carrying out 2-3 time filling and leading up to cylinder discrepancy in elevation place dry ash, new and old cylinder builds place's discrepancy in elevation by laying bricks or stones
And it is levelling that discrepancy in elevation place is filled out ash on brick-laying machine,
8th step: hoop seam is carried out appropriate amount of fine-tuning by kilneye direction in new cylinder building process, the replacing cylinder seam in kiln tail direction is if any the discrepancy in elevation, building method is ditto processed brick masonry, it is processed brick masonry with old brick interface according to actual hoop size, but processing brick must be processed brick masonry with old brick the second ring.
Use the method can ensure new and old cylinder refractory brick entirety modulus, make refractory brick entirety in Dayao runs effectively run, reduce during refractory brick runs crowded broken, make Dayao run and operate on same centrage with refractory brick friction.
Above embodiments is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention are determined.
Part that the present invention does not relate to is all same as the prior art maybe can adopt prior art to be realized.
