Vitreous frit kiln is the heart of product line of float law glass, its service life basically depends on of wall of frit kiln pool, big Xuan, regenerator erode and burn damage level, the care and maintenance that uses kiln furnace and crucial position correctly is to lengthen kiln furnace service life, lengthen all fronts equipment to use those who raise economic benefits is periodic, essential. The article exceeds furnace of kiln of glass of white float law according to some solar energy (furnace of kiln of A of later development abbreviation) example, the maintenance that introduces later period of vitreous frit kiln and use. Classics of this kiln furnace moves more 8 years, the place such as pool bottom, Chi Bi, big Xuan, checker burns caustic badly, took different technical step in the light of different position, improved erode a state, prolonged the service life of this kiln furnace, be in for the enterprise lengthen kiln furnace service life respect provided valuable experience.
1, technical measure
·Pool nogging is subsidized
The main reason of cold repair of domestic frit kiln is Chi Bi appeared to burn caustic badly, accordingly, maintaining wall of pool of good frit kiln is the key that lengthens kiln age. A kiln furnace designs life to be 8 years, to in May 2019, already ran 9 months 7 years, be close to kiln furnace to design life, detected the ply of wall of pool of the frontispiece after end of feed in raw material comes, discover wall of pool of port of two side 3#~5# is eroded serious, small part ply is only 34mm. Already was opposite before wall of pool of A kiln furnace has been subsidized 2 times, the plan undertakes pool nogging the 3rd times subsidize. Subsidize bricky circumstance fully according to place, subsidize ply to be 75mm, height is 700mm, it is below two) on 400mm+300mm(namely, bearing of use 140mm wide channel, still can subsidize for the 4th so take superabundant land. Specific plan is shown 1 times like the graph.

After pool nogging is subsidized, lengthen above of moving half an year again after achieving kiln furnace to design life, did not discover Chi Bi is aglow phenomenon. The basis is computative, below the case that strengthens wind refrigeration, lengthen again after moving 1 year, undertake pool nogging the 4th times subsidize again, still can ensure the health of wall of pool furnace pool moves.
·Solder of pottery and porcelain fills
Pottery and porcelain compiles data as heat but adhesion is damaged in fireproof material area, melt process can produce exothermic reaction temperature to be able to achieve 2200 ℃ , can use material of pottery and porcelain to undertake repairing to 2 oxidation silicon, alumina, AZS and magnesian fireproof material so, solder filling process need not stop kiln, smaller to manufacturing influence. A kiln furnace invites filling manufacturer of solder of pottery and porcelain to a string of 1 to L the fireproof material such as wall, big Xuan, parapet, regenerator erodes serious place to undertake diagnostic regularly, make solder of pottery and porcelain fill. When A kiln furnace moves 6 years, to casting makings mouth L as string of 1 the wall undertook solder fills; When running a month 7 years, be opposite to frit kiln Xuan of port of 1# of side of Xuan top and Xuan foot, north and Xuan foot mix regenerator of port of 1# , 5# big Xuan of fused pool scolex, cast makings mouth L to a string of 1 the wall undertook solder fills; When running 3 months 8 years, a string of 1 to L Xuan carries regenerator of port of 1# of side of wall nose area, north on the head, to 3# port regenerator Xuan foot, to 4# port regenerator Xuan foot and partition, to Xuan was made the same score to undertake solder fills after 5# port. Place of the ablation after solder fills gets repair, "Mousehole " be able to repair, photograph of solder filling around sees a picture 2 with the graph 3.

·Checker dredge
Rate of broken bits of Kong Ji of grid of kiln furnace later period is rapid, jam serious, have local collapse appearance, affect blaze pilot stability not only, and because the likelihood operates aggravation of inadvertent occurrence a got-up affair, bring about ahead of schedule cold repair. Use the measure dredge checker of high temperature melt and union of photograph of artificial dredge law, in order to make sure the air current inside checker of kiln furnace later period is expedite. A kiln furnace moves to later period, basically every 6 months are about serious to jamming regenerator checker undertakes dredge (inverted image of dredge around checker is shown 4 times like the graph) . Except strengthen bit of check to support to the Xuan of discovery " mousehole " , Xuan Cha is burned outside wearing place to be repaired in time, need to establish reasonable regenerator dredge time and method, in order to make sure regenerator moves normally.

·Install supervisory equipment
Furnace of kiln of real time supervisory system moves to later period, carry big Xuan of 3 axes end the pool, fused pool in fused pool feed in raw material early or late quadrilateral, footpath of port lower part east side installed 9 monitoring to photograph like the head, respectively top of leakage of fluid of glass of monitoring pool bottom, Xuan is burned wear, the hidden trouble of the place such as makings of Chi Bi leakage. Be in when class personnel in accuse room through be opposite the place such as Chi Bi of bottom of top of kiln furnace Xuan, pool, port monitors look carefully at, can discover hidden danger with as soon as possible.
Graph 5 monitoring are photographed room picture dominates in be being reached like the head
·Thermal resistance calls the police supervisory system
The wall managing a pool such as neck of 6 pairs of port of the pool, clear to fusing ministry, card and cooling ministry installed 18 thermal resistance, setting temperature calls the police be restricted, room monitoring personnel accuses to be able to affirm to the spot according to temperature change circumstance Chi Bi runs a state in time in.
·Infra-red measure Wen Yi
Bottom of pool of clear to 1# port ministry installed 11 infra-red measure Wen Yi, execute monitoring of real time temperature, monitoring personnel but reduced temperature curve dogs of firebrick erode a state, so that be adopted ahead of schedule,defend measure. When A kiln furnace runs 4 months 8 years, clear ministry blocks neck corner brick to be in Chi Bi to produce slight ooze to expect, monitoring of thermal resistance temperature wants the caution on the horse, operate personnel to expect to ooze place undertook handling in time when the class, avoided the aggravation that kiln furnace ooze expects, won valuable time for rush to repair.
·Increase bosomy bubble implement cooling system
Because rouse bubble implement move for long, wall of canal bosomy bubble is rustily and serious, the backwater temperature that rouses bubble canal individually is restricted to be worth more than, the temperature that drops water of loop of cooling water tower cannot from go up at all eliminate this to rouse bubble implement the hidden trouble that is burned to wear. When A kiln furnace runs 6 months 8 years, 3# rouses bubble canal to be burned to wear, be in next pulling to take out this canal bosomy bubble when, a few glass fluid are poured out of along brick bosomy bubble, immediately suspends this operation, reinsert canal bosomy bubble inside brick bosomy bubble. The analysis thinks A kiln furnace is produced for a long time exceed white glass, pool bottom is eroded serious, stop the ply that pool bottom brick cannot judge before furnace. Increased bosomy bubble for safety implement cooling wind system (see a picture 6) , in case vitreous fluid outflow causes an accident.
Graph 6 add bosomy bubble newly implement cooling wind system
2, epilogue
Kiln furnace safeguards the damage level of type of furnace of need basis kiln, different position to enact different measure. The article exceeds furnace of kiln of glass of white float law mediumly to be subsidized through pool nogging, solder of kiln furnace pottery and porcelain fills, the regenerator checker dredge, installation that how prevents supervisory equipment, increase bosomy bubble implement the measure such as cooling system, assured to exceed the kiln furnace health that designs life to move, for the enterprise managing cost.
