Auftor vynálezu BERÁNEK ČESTMÍR ing., BRATISLAVA (54) Ochrana ocelového plásťa ohrievača větra 1Authors of the invention BERÁNEK ČESTMÍR ing., BRATISLAVA (54) Protection of steel jacket and heater 1
Vynález sa týká ochrany ocelového pláš-ťa ohrievača větra, používaného na výrobuvzduchu u vysokých pecí.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to the protection of a steel jacket of a heater used in a blast furnace manufacturing air.
DosiaT sa ochrana ocelového plášťa ohrie-vača větra realizovala ako monolitická ar-movaná vrstva, ukotvená na ocelová stenutřňmi. Hlavnou nevýhodou tejto známej o-chrany, vložene] medzi plášť a vymurovku,je vysoká časová náročnost' na jej zhotove-nie a vytvrdnutie, značné sú straty mate-riálu pri jej torkretovaní. Práce pri stavběalebo opravě ohrievača větra velmi predl-žuje stavba lešenia, ktoré sa musí urobita rozobrať len pre zhotovenie ochranné]vrstvy, dalej vyčistenie ohrievača po skon-čení torkretovania. Časovo velmi náročnéje i priváranie velkého počtu třňov, ktorésa inštalujú za účelom ukotvit na ocelovýplášť armovacie siete ochrannej vrstvy.Up to now, the protection of the steel casing of the heater has been realized as a monolithic reinforced layer, anchored to the steel by means of a bar. The main disadvantage of this known protective layer, inserted between the shell and the liner, is the high time consuming and curing, considerable material losses are caused by its spraying. Working in the construction or repair of the heater greatly extends the construction of the scaffolding, which must be dismantled only to produce the protective layer, further cleaning the heater after finishing the gunning. It is also very time consuming to weld a large number of mandrels, which are installed in order to anchor the protective layer of the protective layer to the steel casing.
Vyššie uvedené nevýhody odstraňuje o-chrana ocelového plášťa ohrievača větra po-dlá vynálezu. Ochrana je zostavená z vo-pred vyrobených dielcov zo žiarobetónu o-dolného teplotám od 800 do 1200°C. Dielcesú vzájomne spolu spojené v ložných astyčných spárách maltou, resp. tmelom, kaž-dý dielec je navlečený na kotevný tfň a je-ho poloha je zabezpečená poistnou samo-svornou podložkou.The above-mentioned drawbacks are eliminated by the protection of the steel jacket of the heater according to the invention. The protection is made up of prefabricated low temperature refractory parts of 800 to 1200 ° C. Dielces are bonded together in the mating joints by mortar or mortar. sealant, each piece is strung on an anchor and its position is secured by a self-clamping lock.
Ochrana ocelového plášťa ohrievača vet- 2 ra podlá vynálezu je oproti doslal známýmvýhodná najma preto, že významné urýchíu-je práce pri vymurovaní ohrievača větra.Skracuje sa čas potřebný na zhotovenie sa-motnej ochrannej vrstvy, je možné konti-nuálně nasadenie pracovníkov, pretože sasúčasne murujú i izolačně a žiarovzdornévrstvy vymurovky ohrievača.The protection of the steel jacket of the heater of the invention according to the invention is particularly advantageous because of the significant acceleration of the work on the heating of the fan heater. They also masonry and heat resistant layers of the heater.
Značné sú úspory materiálu, nižšia je po-třeba stavieb lešení, docilujú sa úspory naopotřebení strojov, dodávke energií. Velmisa zlepšuje hygiena a zvyšuje bezpečnostpráce. Příklad zhotovenia ochrany ocelovéhoplášta ohrievača větra podlá vynálezu jeschematicky znázorněný na výkrese. Na obr.1 je zvislý rez ohrievačom větra, na obr. 2zvislý rez stěnou ohrievača, obr. 3 je čelnýpohlad na část ochrany, obr. 4 čelný po-hl'ad na dielec, na obr. 5 je rez připevně-ným dieícom. Obr. 2 až 5 sú vo vačšom mě-řítku.Material savings are considerable, scaffolding is less needed, savings on machine consumption, energy supply are achieved. Velmisa improves hygiene and increases work safety. An exemplary embodiment of the protection of a steel heater windshield according to the invention is shown schematically in the drawing. Fig. 1 is a vertical sectional view of the heater, Fig. 2 is a vertical cross-sectional view of the heater, Fig. 3 is a front view of part of the protection, Fig. 4 is a front view of the panel, Fig. 5 is a cross-sectional view of the attached child. FIG. 2 to 5 are larger.
Ochrana 3 ocelového plášťa 1 ohrievačavětra je vložená medzi ocelová stenu a viac-vrstvú vymurovku 2 (obr. 1 a 2). Pozostávaz doskovitých dielcov 4 zo žiarobetónu,ktoré majú rozměry umožňujúce, aby diel-ce sledovali kruhový tvar ocelového plášťa.Dielce 4 sa navliekajú na kotvené trne 7a zaistujú v zvislej polohe samosvornými 225155The steel casing cover 3 of the heater is interposed between the steel wall and the multi-layer lining 2 (FIGS. 1 and 2). The reinforced concrete plate-like panels 4 have dimensions which allow the parts to follow the circular shape of the steel shell. The parts 4 are threaded onto the anchored mandrels 7a and lock in a vertical position by self-locking 225155
