Wynalazek dotyczy dalszej przeróbki sposobu przygotowywania wyfeiofcowartoiscio- wiej sitali i zuzlaowysiokimprocendefosfo^^ przy przeróbce surowca w piecach plomien¬ nych, przy której zawartosc fosforu, zebrana w dwóch poczatkowych zuizlaich, sprowadza sie tdo plynnego zuzla rozpusziciziailnieigo w cy¬ trynianach. Ten sposób jest tylko wykonal¬ nym' przy surowcach, wolnych od krzemu albo ubogich w takowy. Przy uzyciu zelaiza o wysokiej zawartosci krzemu rozciencza tiworzacy sie obficie kwas krzemowy zuzel tak, ze zawartosc kwasu fosforowego w nim obniza sie nizej normy dopuszczalnej w han¬ dlu. Niniejszy sposób umozliwia otrzymanie zizZJlia.iO wysokimi procencie fosforu' takze* z surowica o wysokiej zawartosci krzemu.Dla rozwiazania tego zadania postepuje sie talk, ze jako piietrwBizy zuzel w piecu zialsa- dowym tworzy ,sie kwasny zuzel, zabiera¬ jacy wieksza czesc krzemu i który zawieiria tylko slady kwasu fosforowego tak, ze sklad¬ niki tworzace fosforany pozostaja w piecu, gdzie tworza drugi zuzel,' roEipuiszicziarny w cytrynianach, o wysokim procencie fo¬ sforu. Sposób -ten umozliwilo prowaidizemie procesu w ten sposób, ze kwas krzemowy i foisforoiwy zizmzlaj^ sie oddzielnie. Do ze¬ laza,, zawierajacego krzem i znajdujacego' sie w piecu plomiennymi, dodaje sie tyle rud^. ile potrzeba dla utlenienia krzemu, dodawa¬ nie wiec wapna jest zbytecznie albo ograni¬ czone do minimum. Po dodaniu rudy tworzy sie prawie w mgnieniu oka kwasny zuzel.który, z powodu swego kwasnego charakte¬ ru, zawiera tylko slady kwasu fosforowego.Zuzel wydmuchuje sie albo odlewa, wtedy roztopiony metal jest wolny od "zuzla;, na¬ stepnie zas przystepuje sie do otrzymania zuzla zawierajacego fosforany.Przyklad: Do ladunku surowca zawierajacego okolo 3.5% wegla, 1.5°/0 albo wiecej krzemu, 0.6°/0 albo wiecej fosforu dodaje sie rudy dla utlenienia krzemu. Nastepujaca natych¬ miast silna reakcja daje zuzel z okolo 32% Si02. Zuzel usuwa sie, poozienl icUddaje sie nowej rudy i niewielka ilosc wapna, przy- czem otrzymuje sie thomasowski fosforowy zuzel. Tern zuzel posiada, nawet przy wyzej wspomnianej niskiej zawartosci fosforu, w 'zawairtostó pieca jesizioze pomad 14% roz¬ puszczalnego w cytrynianach kwasu fosfo¬ rowego, moze byc wiec praktycznie wyzy¬ skany.Wiadomem jest, ze surowiec o duzej za¬ wartosci krzemu trzeba najprzód pozbawic takowego i dopiero obrabiac (patrz; Wedding' Grundriss der Eisenhuettenkunde, 5 wyd.., str. 267). Ale gdzie okolicznosci do tego zmuszaja, to do usuwania krzemu stosuje sie kwajsny piec kotlinowy, albo gruszke besseme^owska,. a dla wykonczenia plrzenosi sie ladunek do pieca zasadowego. Wedlug niniejszego; sposobu mozna pracowac tylko przy jednym piecu zasadowym, gdzie ladu¬ nek najpierw pozbawia sie krzemu (tworze¬ nie kwasnego zuzla), a potem fosforu (two¬ rzenie zasadowego zuzla). PL PLThe invention relates to the further processing of the process for the preparation of high-grade, high-quality sitali and high-grade polymeric-phosphate in the processing of the raw material in flame furnaces, whereby the content of phosphorus, collected in the two initial zuizlaich, is reduced to a liquid dilution in cyanogen. This method is only feasible with raw materials that are either silicon free or poor in such. When using irons with a high silicon content, it dilutes the abundantly developing silicic acid in such a way that the phosphoric acid content in it drops below the acceptable standard for trade. The present method makes it possible to obtain a high percentage of phosphorus also from a serum with a high content of silicon. To solve this problem, talc is followed that, as a layer of white gell in the herbal oven, an acidic kell is formed, which takes up most of the silicon and which contains only traces of phosphoric acid so that the phosphate-forming components remain in the oven where they form a second zell, the high-phosphorus grains in the citrate. This method made it possible to initiate the process in such a way that the silicic acid and the phosphorus come together separately. This amount of ore is added to the iron containing silicon in the furnace. as needed to oxidize the silicon, the addition of lime is therefore either unnecessary or kept to a minimum. When the ore is added, an acidic metal is formed almost in the blink of an eye, which, because of its acidic nature, contains only traces of phosphoric acid. to obtain a phosphate-containing slag. Example: For a feed charge containing about 3.5% carbon, 1.5 ° / 0 or more silicon, 0.6 ° / 0 or more phosphorus, ores are added to oxidize the silicon. The following strong reaction gives a slag of about 32 % SiO2. The slag is removed, turned into waste and a small amount of lime is given, resulting in Thomas Phosphorus slag. The Tern Zuzel has, even with the above-mentioned low phosphorus content, in the furnace a fall in autumn with 14% soluble in phosphoric acid citrates, it can therefore be practically exploited. It is known that a raw material with a high silicon content must first be removed and then processed (see; Wedding r Eisenhuettenkunde, 5th ed .., p. 267). But where circumstances force it, a sour basin furnace or a besseme pear is used to remove silicon. and for finishing the load is transferred to the basic furnace. According to this; In this manner, it is possible to work with only one basic furnace, where the liner is first deprived of silicon (acid formation) and then phosphorus (alkaline formation). PL PL
