Description
Przedmiotem wynalazku jest sposób wykladania obmurza kadzi odlewniczych. Wynalazek dotyczy przemyslu materialów ogniotrwalych i przemyslu hutniczego.The subject of the invention is a method of lining the brickwork of foundry ladles. The invention relates to the refractory industry and the steel industry.
Obecnie do budowy obmurza kadzi odlewniczych w stalowniach sluza glównie wyroby ogniotrwale szamotowe i kwarcowo-szamotowe. W warunkach szczególnie trudnych ze wzgledu na temperature odlewania stali i agresywne dzialanie zuzli stosuje sie takze wyroby wysokoglinowe. Wyroby szamotowe i kwarcowo-szamo¬ towe sa laczone zwykle zaprawa kwarcowo-szamotowa, a wyroby wysokoglinowe zaprawa wysokoglinowa.Currently, mainly refractory products are used to build the lining of casting ladles in steel mills chamotte and quartz-chamotte. Under conditions that are particularly difficult due to the casting temperature high-aluminum products are also used in steel and the aggressive action of slags. Fireclay and quartz-slime products These are usually combined with quartz-chamotte mortar, and high-aluminum products - high-alumina mortar.
Wszystkie te zaprawy zarabia sie woda. Zywotnosc obmurza kadzi stalowniczych zbudowanych z wyrobów szamotowych i kwarcowo-szamotowych jest niezadawalajaca. Obserwuje sie czesto miejscowe zniszczenie obmurza w postaci wzer, przenikania zuzla i plynnej stali w spoiny miedzy ksztaltki i inne zjawiska wplywajace niekorzystnie na trwalosc obmurza kadzi.All these mortars make water. Lifetime of brickwork of steel ladles made of products chamotte and quartz-chamotte is unsatisfactory. Local destruction is often observed brickwork in the form of patterns, the penetration of slag and liquid steel into the joints between the shapes and other influencing phenomena unfavorable to the durability of the ladle brickwork.
Istota wynalazku jest sposób, polegajacy na wykladaniu obmurza tej samej kadzi róznymi materialami ogniotrwalymi w zaleznosci od ich umiejscowienia w obmurzu. Odcinki obmurza narazone na szczególnie trudne warunki pracy to jest strefe na linii zuzla, dno kadzi oraz miejsce narazone na pierwsze uderzenie strumienia stali wyklada sie wyrobami wysokogl inowymi, korundowymi lub zasadowymi. Wszystkie inne partie obmurza kadzi wymurowuje sie wyrobami szamotowymi lub kwarcowo-szamotowymi. Do wiazania ksztaltek stosuje sie zaprawy o wyzszej ogniotrwalosci zwyklej w stosunku do wyrobów, zarabiane rozcienczonym szklem wodnym.The essence of the invention is the method of lining the same vat with different materials fireproof depending on their location in the brickwork. Sections of brickwork are particularly difficult working conditions, i.e. the zone on the slope line, the bottom of the ladle and the place exposed to the first impact of the steel stream lined with high-carbon, corundum or alkaline products. All other lots of brick lining is built with chamotte or quartz-chamotte products. It is used to bind the shapes mortars with higher fire resistance, usually compared to products, made with diluted water glass.
Taki sposób wykladania kadzi odlewniczych pozwala na znaczne zwiekszenie ich trwalosci. Zastosowanie do murowania ksztaltek zaprawy o wyzszej ogniotrwalosci zwyklej w stosunku do wyrobów np. zaprawy wysokoglinowej zarabianej szklem wodnym lub zaprawy wysokoglinowej z dodatkiem krzemianu sodu zarabianej woda przeciwdziala skutecznie penetracji zuzla i plynnej stali w glab spoin.This method of lining the casting ladles allows for a significant increase in their durability. Application for building blocks, mortar with higher fire resistance, usually compared to products, e.g. mortar high alumina made with water glass or high alumina mortar with the addition of sodium silicate made water effectively prevents the penetration of the slag and liquid steel into the welds.
W kadziach uzywanych do spuszczania stali z pieców martenowskich przy wytopach zawierajacych duza warstwe zuzla lub w przypadku dlugotrwalego przetrzymywania stali w kadzi przy odlewaniu malych wlewków : wymurowuje sie wylozenie na linii zuzla z dwu warstw wyrobów wysokoglinowych o zawartosci 60% Al203.In ladles used for tapping steel from open-hearth furnaces for melts containing a lot of a layer of slag or in the case of long-term keeping of steel in the ladle when casting small ingots: two layers of high-aluminum products with 60% Al2O3 content are built on the slag line.
Tymi samymi wyrobami wyklada sie czesc sciany narazonej na bezposrednie uderzenie plynnej stali oraz dno kadzi. Cala reszte obmurza kadzi wymurowuje sie wyrobami kwarcowo-szamotowymi o niskiej porowatosci. Do laczenia ksztaltek w obmurzu stosuje sie zaprawe wysokoglinowa o zawartosci 60% tlenku glinu o granulacji 0—1 mm zarabiana rozcienczonym szklem wodnym. {2 89 993 Wynalazek nadaje sie do stosowania w przemysle hutniczym. Sposób wymurowania kadzi odlewniczych wedlug wynalazku zapewnia podwyzszenie ich trwalosci o okolo 30%.The same products are used to cover the part of the wall exposed to direct impact of liquid steel and the bottom ladle. The entire rest of the vat's brickwork is made of quartz-chamotte products of low porosity. Down for joining shapes in the brickwork, a high-alumina mortar containing 60% aluminum oxide with granulation is used 0-1 mm made of diluted water glass. {2 89 993 The invention is applicable to the steel industry. The method of building foundry ladles According to the invention, it increases their durability by about 30%.
