In vitreous industry production, fireproof material is the corporeal condition of vitreous kiln furnace, big to the integral benefit harm of kiln furnace. Vitreous kiln is fireproof first material is the crucial essential factor that endangers return rate of project of project of vitreous frit kiln, it is character of vitreous frit kiln is mixed run what ensure smoothly is important. Vitreous kiln furnace is fireproof material not only use amount is large, the kiln of frit of float law glass that is like a 500t/d class gets the fireproof data that fluctuates with 5000t about, the crucial scale that and expenditure takes cost of entire pit project and even item of whole processing factory invests, reason must be chosen effectively makings.
The guiding ideology that fireproof material chooses vitreous kiln also is mature technical the element that develops 2 levels with economy, with fireproof material physico-chemical character, tectonic means reachs target of critical value function, the corrode caustic principle that parameter of quality of air of job of buy of kiln furnace everybody and raw material lay in tall and mutual report are basic, close spell accumulated relevant kiln furnace and fireproof material specific the detailed and professional knowledge that runs character and specific work experience, fireproof to buy of frit kiln everybody material is begun choose makings and effective mate, exceed corrode caustic balance, as a result increases on active service service life, the best application that reduces project cost is actual the effect. Real provision gives out.
① considers indispensible function target, if dependability of dependability of tall character, organic chemistry, hear resistance, cubage is mixed,pound tenacity.
② not the environment pollutes vitreous fluid, small to harm of vitreous fluid character.
The operating period that ③ grows as far as possible.
④ build by laying bricks or stones different among the fireproof material of material, there was not report of lay a finger on below tall .
⑤ uses ability capacity and hot tube less to come loose as far as possible heat is damaged.
⑥ is fragile the position chooses high quality raw material, other position can be used normally raw material, assure establishment of “ effective form a complete set, kiln age is the same as ” .
Toughened glass factory heats up long means key basically to have the following content with fireproof material.
(The heat of brick of 1) side wall is repaired
Side wall chooses dissolve refine 41#AZ5 after the brick sets upright build by laying bricks or stones, time regulates the applied cycle that can consider frit kiln, heat is repaired 2 make an amount very little already, the pattern that shows 2 kinds of heat that level will choose to repair side wall brick gives out.
Law of conduit of ① cooling loop. Use straight 20? Of 50mm without seam a canal, fluid of the side in ^ of kiln of person of dip of his what is the edge corroded wall below 50? 80mm place, make circumjacent vitreous fluid condenses, of quantity giving water is spent maintain fluctuate in 50 ℃ . 2 laws although effect is distinct, but bad news of promotion hear rate, water, and have the end on side wall of in order to only, in a whole brick great majority is corroded thinner when criterion cannot be successful.
Iron brick way is stuck outside ② . Corrode when side wall brick arrive when 30mm is only thick, can outside stick at the same place the homogeneity brick material of 150mmS (also call the brick that bind iron) . Ceramic tile is stuck to be able to use old brick outside, and be sure to heat to fluctuate to 80 ℃ . The surface among brick and brick should be rectified as far as possible smooth, the brick is seamed should small.
(2) store the heat of brick of hot cell pane is repaired
Because use fight brick of corundum of zirconium of the magnesian chromium brick with strong sex of adhere of alkaline priming paint, magnesia brick, high quality tall purity to wait, store hot cell pane luxuriant already can apply a kiln period. Show level, store the inadequacy that hot cell key exists is grain makings is fused the block of system of standard of the other side after tumor, store what hot cell heats up repaired thematic thought that is to say to maintain pane system is expedite. Eliminate store the means key of tumour of knot of makings of hot cell grain chooses division of mechanical equipment disappear, flame fused disappear division (burn a law instead) etc.
(The heat of 3) nozzle brick is repaired
Nozzle brick is this kind of surprise that kiln of steam derv frit uses brick, this is spray gun shoots the heavy oil via doing pulverization to receive the with combustion gas mix up safe channel inside kiln. By child nozzle brick is in crater place, instantly flame of lay a finger on, very easy by burn down: ? ┑ of spurt Qian Man Xie relies on Yi reed to overspread Ping sulphone banter by arc of Gua of Σ of A Chinese-style unlined garment 2 Gua bad Mu wrings the Kuo that cast glow to wish daughter-in-law of ┥ of Man of Qian of of of an ancient drinking vessel of 〕 of cereal of Kong of Jin of of acute hearing Ran whistles > eye barrier fights Chinese alligator of 〕 of of brighting Deng, change former position, wipe severe empty rift, mount spray gun, and repair its pose, heat is repaired accuse namely undertake.
The heat of traditional pattern builds kind difficult environment, labor efficiency is big, after choosing tall Ji fireproof material, alleviate already a lot of • but still be relatively hard and multifarious job in, normal to everything production is made have dry flinch. The vulcanize that shows level and hot oxygen gush fill the standard that can make heat is repaired is improved, to staff member and machine equipment more security, had been popularized by sale and choose.
Vulcanize is applicable caustic of corrode of the later period in frit kiln is fireproof the structural consolidate of material, or block eyelet, will put the environment pollutes glass
Kiln of frit of fluid, harm the difficult problem such as all regular jobs. Treatment involving the use of tonics to restore the patient's health of hot oxygen gush is a basis to wait for fill grain of fire prevention material expects like spew of fireproof material point and and so on, make its solder from frit electric welding below tall , make be able to bear or endure then the way that person raw material mends. Hot oxygen way can be quick security ground begins vulcanize to fireproof material, not only the fireproof material to general corrode decrease and attaint, and be aimed at move or the fireproof material that smash occasionally, and even be seamed to filling or the plug-hole seat that develops with law of traditional pattern vulcanize all very reasonable, this kind of means is helpful for promoting frit kiln working efficiency.
