Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania proszków w procesie recyclingu wiórów stalowych, który polega na tym, że wióry poddaje się prasowaniu na zimno w czasie od 5 do 10 minut, przy czym nacisk prasy na wióry wynosi od 160 do 200 T. Następnie sprasowane wióry zanurza się w rozpuszczalniku organicznym na okres od 25 do 35 minut w temperaturze od 40 do 50 stopni C. Po wyjęciu sprasowanych i umytych wiórów z rozpuszczalnika umieszcza się je w piecu komorowym w temperaturze od 100 do 150 stopni C, a następnie w piecu indukcyjnym w temperaturze od 1400 do 1550 stopni C i doprowadza się do całkowitego stopienia. Tak uzyskany stop wlewa się do form odlewniczych i pozostawia do wystudzenia, a po wystudzeniu odlany materiał poddaje się procesowi śrutowania, usuwając w jego efekcie warstwę tlenkową. Następnie odlew poddaje się atomizacji, uzyskując proszek o średnicy od 20 do 100 µm.The subject of the application is a method of producing powders in the process of recycling steel chips, which consists in the fact that the chips are subjected to cold pressing within 5 to 10 minutes, with the press pressure on the chips from 160 to 200 T. Then the pressed chips are immersed in an organic solvent for a period of 25 to 35 minutes at a temperature of 40 to 50 degrees C. After removing the pressed and washed chips from the solvent, they are placed in a chamber furnace at a temperature of 100 to 150 degrees C, and then in an induction furnace at a temperature of 1400 to 1550 degrees C and is completely melted. The alloy thus obtained is poured into foundry molds and allowed to cool, and after cooling, the cast material is blasted, removing the oxide layer as a result. The cast is then atomized to give a powder with a diameter of 20 to 100 µm.
