Abstract

Sposób wytwarzania jednorodnych materiałów na certyfikowane materiały odniesienia do spektralnej analizy cynku za pomocą pieca indukcyjnego tyglowego, polegający na wtapianiu do czystego cynku dodatkowych pierwiastków i stopów wstępnych, charakteryzuje się tym, że w pierwszym etapie amalgamat Hg/Ag (stosunek amalgamatu 1:1) wykonany poprzez mieszanie metalicznego proszku srebra z ciekłą rtęcią przy użyciu młynka planetarnego w 11 rewersyjnych cyklach, gdzie każdy cykl obejmuje mieszanie z prędkością obrotową 300 obr./min w ciągu 5 minut z 1 minutowym postojem między cyklami i sprasowany na prasie hydraulicznej z naciskiem 300 kN, przy ciśnieniu prasowania 448 MPa w ciągu 60 s w celu uzyskania wyprasek o średnicy 20 mm i wysokości 8 mm, wtapia się do roztopionego cynku o temperaturze 480°C i wylewa do zimnej płaskiej wlewnicy żeliwnej, uzyskując tym samym płytę o grubości nie większej niż 5 mm stopu wstępnego ZnHg3(Ag) o zawartości rtęci w stopie wstępnym namiarowanej na 3%, po czym w drugim etapie do tygla szamotowo-grafitowego wsaduje się cynk, roztapia go i przegrzewa do temperatury 650°C i wtapia stop wstępny ZnCr1,5, następnie po dokładnym wymieszaniu tak wytworzonej mieszaniny odlewa się ją do wlewnicy i studzi uzyskując wlewek stopu ZnCr, po czym w trzecim etapie wytworzony w drugim etapie wlewek stopu ZnCr ładuje się do pieca, topi się i do kąpieli o temperaturze 550°C dodaje kolejno stop wstępny w gatunku ZnCd20 oraz ołów i po mieszaniu przez 5 min prętem grafitowym dodaje stop wstępny ZnHg3(Ag) powstały w pierwszym etapie, cały czas mieszając indukcyjnie ciekły metal, a następnie po mechanicznym wymieszaniu prętem grafitowym odlewa do zimnych kokil żeliwnych.A method of producing homogeneous materials for certified reference materials for spectral analysis of zinc using a crucible induction furnace, consisting in fusing additional elements and pre-alloys to pure zinc, is characterized in that in the first stage, a Hg/Ag amalgam (amalgam ratio 1:1) made by mixing metallic silver powder with liquid mercury using a planetary mill in 11 reversible cycles, where each cycle includes mixing at a rotational speed of 300 rpm for 5 minutes with a 1-minute break between cycles and pressed on a hydraulic press with a pressure of 300 kN, at a pressing pressure of 448 MPa for 60 s in order to obtain compacts with a diameter of 20 mm and a height of 8 mm, is fused into molten zinc at a temperature of 480°C and poured into a cold flat cast iron ingot mold, obtaining at the same time, a plate of no more than 5 mm thickness of the ZnHg3(Ag) prealloy with a mercury content in the prealloy measured at 3%, then in the second stage zinc is put into a fireclay-graphite crucible, melted and overheated to a temperature of 650°C and the ZnCr1.5 prealloy is melted, then after thoroughly mixing the mixture thus produced, it is poured into an ingot mould and cooled to obtain an ingot of the ZnCr alloy, then in the third stage the ZnCr alloy ingot produced in the second stage is charged into a furnace, melted and the ZnCd20 prealloy and lead are added successively to the bath at a temperature of 550°C and after stirring for 5 minutes with a graphite rod, the ZnHg3(Ag) prealloy formed in the first stage is added, the liquid metal is continuously stirred inductively, and then after mechanically stirring with a graphite rod it is poured into cold cast iron chill molds.
