W przemysle cementowym do wykla¬ dania pieców sizybowych i obrotowych znaj¬ duje obszerne zastosowanie cegla ognio¬ trwala, tak zwana szamotowa. Cegla ta pod wplywem wapna i zelaza, wchodza¬ cych w sklad materialów surowych, uzywa¬ nych do wypalania cementu, ulega szybkie¬ mu zuzyciu, wskutek czego produkcja cze¬ sto ulega przerwie z powodu koniecznosci naiprajwy wykladziny pieca, co wrazi z wy¬ sokim kosztem, cegly szaimotowej, sprowa¬ dzanej z zaigjramilcy, przewaznie podnosi ko¬ szty produkcji.Obok cegly szamotowej stosuja w cza¬ sach ostatnich cegle talk zwana betonowa, wyrabilaina z cementu i Winkiem cemento¬ wego; cegla tai, jako produkt! wiazania ce¬ mentu, pod wplywem wysokiej temperatu¬ ry szybko sie rozpada i1 zuzywa.Cegla ogniotrwala, stanowiaca przed¬ miot wynalaizku niniejszego, wolnai jest od wszystkich wyluszczonych powyzej braków.Wyrabial sie ona z malterjalu, otrzymanego droga stapiania w temperaturze bardzo wy¬ sokiej i pozbawionego srodków wiazacych.Dzieki tej ostatniej okolicznosci cegla ta posiada w temperajttttrze pieca cementowego trwalosc i odlpoimoisc dlostattecznia. Przy wyrobie nowej cegly postepuje sie w sposób nastepujacy: mieszanine wapna i gliny z dodatkiem chlorku wapnibwego oraz soli kuchennej stapiiai sie w ipilecu elektrycznym w tempe¬ raturze docbodzapej do 1800° C, poczem ma/terjal ten, bedacy w stalnie plynnym, wlewa -sie do form, otrzymujac w ten sposób gotowa cegle do wykladania wskazatnych powyzej pieców.Poniewaz wypalalnie cementu odbywa sie w temperaifcurze (tylko) 1500° C, cegla otrzymaina w sposób powyzszy wykazuje znakomita odpornosc ii pozwala: naJ prowar dzenie pieca przez dluzszy okres czasu bez jakichkolwiek przerw. Poza tern cegla ta ze wzgledu na swój swoisty ksizftalt! che- miiczliy, zblizony do skladu cementu, nie ulega pralwiie wcaile zuzyciu, oo naJdaje jej wysioka wartosc i) dlugotrwalosc.Jak wynika z opisu powyzszego, wyrób nowej cegly jest znacznie tanszy; odpajda zupelnie ksztaltowanie cegly i nastepuja¬ ce potem wypalanie, cegle bowiem otrzy¬ muje sie droga bezposrediniejgo odlewania. PLIn the cement industry, fire-resistant brick, the so-called fire-clay, is widely used for the lining of shaft and rotary kilns. This brick, under the influence of lime and iron, which are part of the raw materials used for cement firing, wears out quickly, as a result of which production is often interrupted due to the need for the lining of the furnace, which together with a high at the expense of fireclay bricks, made of gringers, usually increases the cost of production. Alongside fireclay bricks, in recent times they use talcum talc, made of cement, and cement grit; tai brick, as a product! Cement binding, under the influence of high temperature, quickly disintegrates and wears. Refractory brick, which is the subject of the present invention, is free from all the deficiencies listed above. It was made of malterial, obtained by melting at a very high temperature Thanks to the latter, the brick is durable at the temperature of a cement kiln and has a long lifespan. When making a new brick, the procedure is as follows: a mixture of lime and clay with the addition of calcium chloride and table salt is melted in an electric wire at a temperature of up to 1800 ° C, and then the material, which is in a liquid junction, is poured As cement firing takes place at a temperature of (only) 1500 ° C, the brick obtained in this way exhibits excellent resistance and allows: to run the furnace for a longer period of time without any breaks. Besides, this brick is because of its peculiar xizftalt! Chemical, similar to the composition of cement, it is not subject to wear and tear, because it gives it a high value and) long durability. As the above description shows, the production of a new brick is much cheaper; The shaping of the brick and the subsequent firing are completely eliminated, since the brick is obtained by the direct casting path.
