Description
Wynalazek niniiejiszy dotyczy sposobu bezposredniego otrzymywania zelaza z rudy zelaznej. Stosownie do wynalazku proszkuje sie mialko tak rude jak i skladniki odtlenia- jace i czesci dodatkowe, celem otrzymania scislejszego laczenia sie czastek, wreszcie miesza sie dokladnie te sproszkowane ciala, dodajac równoczesnie okolo l,5°/0 cial zle¬ piajacych i wody (mozliwie najmniejsza ilosc) dla otrzymania jednostajnego ciasta, z, którego wyrabia sie cegielki pod cisnie¬ niem. Cegielki te poddaje sie odtlenianiu, topiac je w piecu elektrycznym przy tem¬ peraturze mniej wiecej '800° C.Do odtleniania uzywa sie wegla drzew¬ nego, torfu, lub jakiegokolwiek innego ro- dztaij-u wegla, dajacego miala ilosc popiolu i pozbawionego siarki.Do wytworzenia cegielek mozna uzywac melasy, dekstryny, krochmalu, gumy i róz¬ nych odmian smoly.Ilosci wegla sa rozmaite, stosownie do tego, czy ma sie otrzymac zelazo zwykle, stial lub surowiec. Tak np. pirzy zelafcie, ilosc wegla potrzebna do odtleniania rudy wynosi mniej wiecej 10 czesci na 100 czesci rudy. Przy surowcu uzywa sie wieksza ilosc procentowa wegla, która zmienia sie stosow¬ nie do tego, czy surowiec ma byc wiecej. czy mniej weglisty.Przy wyrobie stali uzywa sie cial odtle- niajacych w ilosci posredniej miedzy iloscia. uzywana przy wyrobie zwyklego zelaza i przy wyrobie surowca.Jalko doidaitlki, w celu przyspieszenia, zuzlowania (obnizeriiia temperatury) uzywasie weglika wapniowego lub szpatu fluoro¬ wego w ilosci miniej wiecej 3 kg weglika 'wapniowego i 0,250 kg fluuoroHSizpaitu m'ia 100 kg rudy zelaznej. Te (ilosci dodatków moga sie zreszita zmieniac^ stosowniile d'o jakosci rud pokladowych, towarzyszacych rudzie ze¬ laznej. Dodatki te sluza doi przemiany sklad- mikó^w rudy pokladiowej nai itazeiniany i gli¬ niany waipnia.Mieszanina, zlozona stosownie do przepi¬ sów powyzszych, przerabia sie na ciasto z domieszka mniej wiecej 1—1,5°/0 melasy i wody w ilosci dostatecznej do otrzymania ciala ciastowatego, z którego tworzy sie przez proste ugniatanie cegielki o ksztalcie prostopadloscianu, cylindra lub owalnym.Zamiast melasy mozna stosowac. smole torfowa lub inna substancje palna w ilosci takiej," by powstala masa, nadajaca sie do ksztaltowania prostokatnych, cylindrycznych lub owalnych cegielek. Cisnienie stosowane przy wyrobie tych cegiel jesit stosunkowo nieznaczne, dzieki lepkosci materjalów la¬ czacych.Odtlenianie rudy zelaznej na zelazo me¬ taliczne odbywa sie przez roztopienie cegiel przy temperiaJturizie 800—850° C, która jed¬ nak jest wyzsza, im mniejsza jest ilosc sto¬ sowanego wegla. Topienie to odbywa sie w szczelnie zamknietym piecu elektrycznym, celem niedopuszczenia powietrza i utrzyma^ nia bardziej odmieniajacej atmosfery. PL PLThe present invention relates to a method of directly obtaining iron from iron ore. According to the invention, both the ore powder and the de-oxygenating ingredients and additives are pulverized to obtain a tighter fusion of the particles, and finally these powdered bodies are thoroughly mixed, while adding at the same time about 1.5% adulterated bodies and water (possibly the smallest amount) to obtain a uniform dough, from which the bricks are made under pressure. These bricks are deoxidized by melting them in an electric furnace at a temperature of about 800 ° C. Charcoal is used for deoxidation, peat or any other type of coal that gives a fine amount of ash and is free of sulfur. Molasses, dextrin, starch, rubber and different varieties of tar can be used to make bricks. The amounts of coal vary according to whether it is to get iron usually, steel or raw material. For example, when sawing iron, the amount of carbon needed to deoxidize ore is approximately 10 parts per 100 parts of ore. A higher percentage of carbon is used for the raw material, which varies according to whether the raw material is to be more. or less coarse. For the production of steel, lightening bodies are used in an amount in between. used in the production of ordinary iron and in the production of raw materials.Also, in order to accelerate, loosen (reduce the temperature), use calcium carbide or fluorine spar in an amount of at least 3 kg of calcium carbide and 0.250 kg of fluuoro HSispaite, equal to 100 kg of iron ore . These (additionally, the amounts of additives may vary according to the quality of the on-board ores accompanying the iron ore. These additives serve to transform the composition of the board ore into it and the clay and lime clay. The mixture is composed according to the balance of the ore. of the above words, make a dough with an admixture of approximately 1-1.5 ° / 0 molasses and water in sufficient quantity to obtain a pasty body, which is formed by simple kneading cubes in the shape of a cuboid, cylinder or oval. Instead of molasses can be used peat tar or other combustible substances in an amount "to form a mass suitable for the formation of rectangular, cylindrical or oval bricks. The pressure used in the manufacture of these bricks is relatively low, due to the viscosity of the bonding materials. Oxidation of iron ore to iron. The potency is achieved by melting the bricks at a temperature of 800-850 ° C. coal. This melting takes place in a sealed electric furnace to keep air out and to maintain a more transforming atmosphere. PL PL
