Description

Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 21.04.1975 77697 KI. 40a,21/06 MKP C22b 21/06 ¦I J Twórcywynalazku: Irena Pajek, Kazimierz Biedron Uprawniony z patentu tymczasowego: Zaklady Metali Lekkich „Kety" Przedsiebiorstwo Panstwowe, Kety (Polska) Topnikdo rafinowania aluminium i jego stopów Przedmiotem wynalazku jest topnik do rafinowania aluminium i jego stopów, przeznaczonych zarówno na odlewy jak tez na wlewki do przeróbki plastycznej.Stosowany szesciochloroetan i fluorokrzemian sodu do rafinowania aluminium i jego stopów w piecu topidnym lub odstojowym ma na celu usuniecie wtracen niemetalicznych i gazowych z kapieli metalu.Wymienione wprowadzone sole do cieklego metalu powoduja gwaltowne burzenie kapieli i wypryski metalu, a pecherzyki wydobywajacych sie gazów w trakcie procesu odgazowania posiadaja duze wymiary przez co powierzchnia styku czynnika rafinujacego z metalem jest mala.Celem wynalazku jest topnik zapewniajacy lagodny przebieg reakcji oraz zwiekszenie efektywnosci procesu rafinacji. * Topnik do rafinowania aluminium i jego stopów wedlug wynalazku zawiera: szesciochloroetan — 37 — 45% wagowych fluorokrzemian sodu 12 — 19% wagowych chlorek potasu 19 - 24% wagowych chloreksodu 11 - 15% wagowych kriolit 8 - 12% wagowych Przyklad skladu topnika do rafinowania aluminium i jego stopów: szesciochloroetan 40% fluorokrzemian sodu 15% chlorek potasu 22% chlorek sodu 13% kriolit 10% Topnik przygotowuje sie przez zmieszanie skladników w okreslonych proporcjach, przetopienie a po odlaniu rozdrobnienie do postaci proszkowej.2 77 697 Dodatek topnika w ilosci 0,3-0,5% od ciezaru wsadu powoduje obnizenie zawartosci wodoru oraz wtracen niemetalicznych glównie tlenku aluminium oraz przedluzenie czasu reakcji a przez to poprawe efektywnosci procesu. Topnikpowyzszy nie moze byc stosowany do stopów aluminium-magnez. PL PLPriority: Application announced: May 30, 1973 Patent description was published: April 21, 1975 77697 KI. 40a, 21/06 MKP C22b 21/06 ¦IJ Inventors: Irena Pajek, Kazimierz Biedron Authorized by the provisional patent: Zaklady Metali Lekkich "Kety" Przedsiębiorstwo Panstwowe, Kety (Poland) Flux for refining aluminum and its alloys The subject of the invention is a flux for refining aluminum and its alloys, intended both for castings and for ingots for plastic working. The use of hexachloroethane and sodium fluorosilicate for the refining of aluminum and its alloys in a melting or stagnant furnace is aimed at removing non-metallic and gaseous waste from the metal bath. they cause rapid bath destruction and metal spatter, and the bubbles of escaping gases during the degassing process have large dimensions, so that the contact surface of the refining agent with the metal is small. The purpose of the invention is a flux ensuring a smooth reaction and increasing the efficiency of the refining process. * Flux for refining aluminum and its alloys according to the invention it contains: hexachloroethane - 37 - 45% by weight sodium fluorosilicate 12 - 19% by weight potassium chloride 19 - 24% by weight sodium chloride 11 - 15% by weight cryolite 8 - 12% by weight Example of the composition of a flux for refining aluminum and its alloys: hexachloroethane 40% sodium fluorosilicate 15% potassium chloride 22% sodium chloride 13% cryolite 10% The flux is prepared by mixing components in specified proportions, remelting and, after casting, grinding to a powder form. 2 77 697 Addition of flux in the amount of 0.3-0.5% from The weight of the charge causes a reduction in the hydrogen content and the inclusion of non-metals, mainly aluminum oxide, and extends the reaction time, and thus improves the efficiency of the process. The above flux may not be used for aluminum-magnesium alloys. PL PL
