Pierwszenstwo: Zgloszenie ogloszono: 01.06.1973 Opis patentowy opublikowano: 30.09.1975 78663 KI. lOb, 5/04 MKP C101 10/02 Twórcy wynalazku: Ignacy Ciupka, Jan Rychly, Zdzislaw Zakrzewski, Henryk Zielinski, Adam Mazur Uprawniony z patentu tymczasowego: Instytut Chemicznej Przeróbki Wegla, Zabrze (Polska) Sposób produkcji paliwa formowanego Przedmiotem wynalazku jest sposób produkcji paliwa formowanego przeznaczonego dla celów hutniczych, odlewniczych lub stosowanego jako paliwa bezdymne.Znany jest fakt, ze z zawartej, w stosowanym dotychczas koksie, siarki, w procesach metalurgicznych podczas wykorzystywania koksu, przechodzi do zeliwa lub surówki znaczna jej czesc, bo 40-70% jej zawartosci w koksie.W stosowanej obecnie praktyce obnizenie zawartosci siarki w metalu odbywa sie poprzez kosztowne i klopotliwe zabiegi, jak na przyklad dodawanie sody do fazy roztopionej.Celem wynalazku jest zmniejszenie zawartosci siarki w zeliwie lub surówce bez stosowania dodatkowych procesów odsiarczania.Zagadnienie techniczne, rozwiazujace postawiony cel, polegalo na wprowadzeniu odpowiednich dodatków do mieszanki brykietowniczej i opracowaniu zmodyfikowanej technologii produkcji paliwa formowanego.Sposób wedlug wynalazku polega na dodaniu do masy brykietowniczej, przed uformowaniem jej w brykie¬ ty, rudy tlenowej manganu lub zwiazków tlenowych manganu w ilosci 1—10% wagowych w stosunku do suchej masy. Nastepnie formuje sie brykiety i poddaje je w znany sposób obróbce tlenowo-termicznej. Wprowadzenie takich ilosci rud tlenowych manganu lub zwiazków tlenowych manganu powoduje zmniejszenie o 20 i wiecej procent zawartosci siarki w metalu. Równomierne rozprowadzenie opisanych zwiazków manganowych w masie brykietowniczej sprzyja bowiem zwiekszeniu rozpuszczalnosci siarki w zuzlu, przez co mniejsza jej ilosc przecho¬ dzi do metalu.Jako dodatkowy, pozytywny efekt stosowania rud tlenowych manganu lub zwiazków tlenowych manganu w mieszankach brykietowniczych - uzyskuje sie znaczna poprawe parametrów wytrzymalosciowych brykietów, co wynika z katalitycznego wplywu zwiazków manganu na reakcje polikondensacyjne, zachodzace w substancji lepiszczowej. PL PLPriority: Application announced: June 1, 1973 Patent description was published: September 30, 1975 78663 KI. lOb, 5/04 MKP C101 10/02 Creators of the invention: Ignacy Ciupka, Jan Rychly, Zdzislaw Zakrzewski, Henryk Zielinski, Adam Mazur Authorized by the provisional patent: Institute for Chemical Processing of Coal, Zabrze (Poland) Method of producing molded fuel The subject of the invention is the method of production Shaped fuel intended for metallurgical and foundry purposes or used as smokeless fuel It is known that the sulfur contained in the coke used so far, in metallurgical processes when coke is used, goes to cast iron or pig iron, a significant part of it, i.e. 40-70% Its content in coke. In current practice, the reduction of the sulfur content in the metal is achieved through costly and troublesome procedures, such as adding soda to the molten phase. The aim of the invention is to reduce the sulfur content in cast iron or pig iron without the use of additional desulphurization processes. Technical issue, solving the set goal was to introduce appropriate additions The method according to the invention consists in adding to the briquette mass, before forming it into briquettes, manganese oxygen ore or manganese oxygen compounds in the amount of 1 to 10% by weight of dry mass. Next, briquettes are formed and subjected to an oxygen-thermal treatment in a known manner. The introduction of such amounts of manganese oxy ores or manganese oxy compounds results in a reduction of 20 percent or more of the sulfur content of the metal. The even distribution of the described manganese compounds in the briquetting mass contributes to the increase in the solubility of sulfur in the slag, thus reducing its amount into the metal. briquettes, which results from the catalytic effect of manganese compounds on the polycondensation reactions taking place in the binder substance.
