Abstract
Sposób usuwania ze złomu stopów aluminium trwale związanych elementów ze stopów zawierających żelazo charakteryzuje się tym, że na sicie wykonanym z prętów lub taśm stalowych, powlekanych materiałem ceramicznym, stanowiącym mieszaninę tlenku aluminium i krzemu, wyposażonym w obejmę, wykonaną z blachy stalowej, umieszcza się kawałki złomu stopów aluminium trwale związanych z elementami ze stopów zawierających żelazo, przy czym masa kawałków złomu stopów aluminium umieszczonych na sicie wynosi 1 - 10% nominalnej pojemności pieca indukcyjnego określonej w kg. Następnie sito wraz ze znajdującym się na nim złomem opuszcza się do pieca i zanurza w ciekłej kąpieli o temperaturze 750 - 830°C, której masa wynosi 25 - 35% nominalnej pojemności pieca określonej w kg, utworzonej z wcześniej dodanego niezanieczyszczonego złomu stopów aluminium lub kąpieli celowo pozostawionej z poprzedniego wytopu. Po przejściu stopów aluminium z umieszczonego na sicie złomu w stan ciekły, sito wyciąga się z pieca wraz z elementami w stanie stałym ze stopów zawierających żelazo, po czym schłodzoną kąpiel wygrzewa się do temperatury 750 - 830°C. Z kolei opuszcza się na sicie kolejną partię przetwarzanego złomu stopów aluminium i prowadzi proces do wyczerpania nominalnej pojemności pieca.The method of removing permanently bound elements from iron-containing alloys from scrap of aluminum alloys is characterized by the fact that on a sieve made of steel bars or strips, coated with a ceramic material constituting a mixture of aluminum oxide and silicon, equipped with a clamp made of steel sheet, pieces are placed scrap aluminum alloys permanently associated with elements containing iron alloys, the mass of scrap aluminum alloys placed on the sieve being 1 - 10% of the nominal capacity of the induction furnace specified in kg. Then the sieve with scrap on it is lowered into the furnace and immersed in a liquid bath at a temperature of 750 - 830 ° C, whose mass is 25 - 35% of the nominal capacity of the furnace specified in kg, formed from previously added non-contaminated scrap of aluminum alloys or bath intentionally left behind from the previous smelting. After the aluminum alloys pass from the scrap metal placed on the sieve to a liquid state, the sieve is removed from the furnace together with solid elements from iron-containing alloys, after which the cooled bath is heated to a temperature of 750 - 830 ° C. In turn, another batch of processed aluminum alloy scrap leaves on the sieve and runs until the nominal furnace capacity is exhausted.
