Description
Przedmiotem wynalazku jest srodek rafinujacy dla aluminium (lub jego stopów, znajdujacy za¬ stosowanie w technologii przygotowania cieklego aluminium lub jego stopów.The present invention relates to a refining agent for aluminum (or its alloys, found use in liquid preparation technology aluminum or its alloys.
Znanym dotychczas srodkiem rafinujacym jest szesciochloroetan, który wykazuje stosunkowo mala efektywnosc dzialania, ze wzgledu na to, ze za¬ chodzaca w podwyzszonych temperaturach reakcja jego rozkladu przebiega bardzo szybko, a czas trwania rafinacji jest krótki.A hitherto known refining agent is hexachloroethane, which is relatively small effectiveness of operation, due to the fact that reaction that runs at elevated temperatures its decomposition proceeds very quickly and time duration of refining is short.
Celem wynalazku jest opracowanie srodka rafi¬ nujacego dla aluminium lub jego stopów, inten¬ sywnie usuwajacego rozpuszczone gazy, szkodliwie wplywajace na jakosc otrzymywanych stopów.The object of the invention is to develop a refining agent bearing for aluminum or its alloys, int vigorously removing dissolved gases, harmful affecting the quality of the alloys obtained.
Istota wynalazku polega na tym, ze srodek ra¬ finujacy zawiera ciezarowo 0—10°/o siarki, 5—20% chlorku potasu, 2—15% siarczanu sodu, 3—20% kriolitu i 50—80% szesciochloroetanu. Srodek wpro¬ wadza sie do stopionego aluminium lub jego sto¬ pów w postaci sproszkowanej lub sprasowanej w ilosci 0,1—0,4% ciezarowych w stosunku do wsadu metalowego.The essence of the invention consists in the fact that the remedy of finisher contains 0-10% by weight of sulfur, 5-20% potassium chloride, 2 - 15% sodium sulphate, 3 - 20% cryolite and 50-80% hexachloroethane. The measure will be introduced it is added to molten aluminum or its alloy in a powdered or pressed form amounts of 0.1-0.4% by weight with respect to the input metal.
Srodek rafinujacy, wedlug wynalazku, wykazuje znaczna wyzszosc pod wzgledem intensywnosci od- gazowania w porównaniu z% samym szesciochloroeta- nem, dzieki temu, ze wchodzace w sklad srodka skladniki powoduja zmniejszenie szybkosci zacho¬ dzacych reakcji rozkladu szesciochloroetanu. Po¬ nadto siarka, wystepujaca w temperaturze rafi¬ nacji w postaci pary wiaze wodór rozpuszczony w cieklym metalu. Siarczan sodu i chlorek potasu powoduja obnizenie temperatury topnienia srodka, a kriolit dziala absorbujaco, pochlaniajac tlenek aluminium.The refining agent, according to the invention, shows significant superiority in terms of the intensity of gassing compared to% hexachloroethe alone nem, thanks to the fact that the composition of the agent ingredients cause a reduction in the speed of conservation the active decomposition reaction of hexachloroethane. Mon. moreover, the sulfur which is present at the temperature of the refinery the nation in the form of a vapor binds hydrogen dissolved in liquid metal. Sodium sulfate and potassium chloride cause a lowering of the agent's melting point, and the cryolite has an absorbing effect, absorbing the oxide aluminum.
W wyniku zastosowania srodka rafinujacego, wedlug wynalazku, uzyskuje sie lepsze wlas¬ nosci mechaniczne i fizykochemiczne oraz wzrost gestosci stopu, co wplywa na poprawe jakosci wykonanych odlewów lub wlewków.As a result of the application of a refining agent, according to the invention, better properties are obtained mechanical and physicochemical bearing and growth alloy density, which improves the quality made castings or ingots.
Przyklad. Srodek rafinujacy zawierajacy cie¬ zarowo nastepujace skladniki: siarka — 5%, siar¬ czan sodu — 5%, chlorek potasu — 5%, kriolit — % oraz szesciochloroetan — 70%, wprowadzono w postaci sproszkowanej, o uziarnieniu nie prze- !5 kraczajacym 1,5 mm, w ilosci 0,4% w stosunku do ciezaru wsadu, którym byl stop aluminiowy AG 10. Po rafinacji stop wykazal wzrost liczby gazowej do 99,6% podczas, gdy stop rafinowany za pomoca samego szesciochloroetanu ma liczbe ga- zowa równa 98,8%.Example. Refining agent containing shadow both the following ingredients: sulfur - 5%, sulfur sodium chloride - 5%, potassium chloride - 5%, cryolite - % and hexachloroethane - 70%, introduced in powder form, grain size not exceeding ! 5 extending 1.5 mm in an amount of 0.4% in the ratio to the weight of the charge, which was an aluminum alloy AG 10. After refining, the alloy showed an increase in numbers gas up to 99.6% while the refined alloy too using hexachloroethane alone has a number of head equal to 98.8%.
