Aanvrager: Manneamann Aktiengesellschaft, Düsseldorf, Bondsrepubliek Duitsland.Applicant: Manneamann Aktiengesellschaft, Düsseldorf, Federal Republic of Germany.
Korte aanduiding: Kolomvormige gietwals met een oorrosiebestendige, wrijvings-vaste beschermlaag.Short designation: Column-shaped casting roller with an anti-corrosion, friction-resistant protective layer.
55
De uitvinding heeft betrekking op een kolomvormige gietwals met een oorrosiebestendige, wrijvingsvaste beschermlaag.The invention relates to a columnar casting roller with an anti-corrosion, friction-resistant protective layer.
Het is bekend een grondstof van een kolomvormige gietwals door od-sproeien van een beschermlaag bestendig te maken tegen spanningsbreuken.It is known to make a raw material of a columnar casting roller resistant to stress fractures by od-spraying a protective layer.
10 Bovendien is het bekend de op de grondstof opgesproeide beschermlaag te sinteren, om daardoor een hogere hechtvermogen te bereiken.Moreover, it is known to sinter the protective layer sprayed on the raw material in order to achieve a higher adhesion capacity.
In tegenstelling tot de gesproeide lagen, die uit een mengsel van metaal en metaaloxyden bestaan, bestaam de gesinterde lagen uit zuiver metaal.In contrast to the sprayed layers, which consist of a mixture of metal and metal oxides, the sintered layers consisted of pure metal.
Bij de bekende kolomvormige gietwalsen, voorzien van beschermlagen 15 die hierboven is beschreven, treden bij buigspanningen breuken op de kristallen op, die gedurende het bedrijf een binnendringen van corrosieve media mogelijk maken. Op deze manier wordt het hechtvermogen van de beschermlaag op de grondstof door corrosie daarvan tegengewerkt.In the known columnar casting rollers, provided with protective layers described above, fractures occur on the crystals during bending stresses, which allow the penetration of corrosive media during operation. In this way, the adhesion of the protective layer to the raw material is counteracted by corrosion thereof.
Het doel van de onderhavige uitvinding is een kolomvormige gietwals 20 te vervaardigen met een oorrosiebestendige wrijvingsvaste beschermingslaag, die ook bij hoge buigspanningen en de hierbij optredende breukvorming een zekere bescherming van de grondstof tegen corrosie gewaarborgd.The object of the present invention is to produce a columnar casting roll 20 with an anti-corrosion resistant friction-resistant protective layer, which guarantees a certain protection of the raw material against corrosion even under high bending stresses and the resulting fracture formation.
Dit doel wordt door de onderhavige uitvinding bereikt met een kolomvormige gietwals, die het kenmerk heeft, dat tussen een grondstof van de wals 25 en de wrijvingsvaste en oorrosiebestendige beschermlaag een duktiele eveneens oorrosiebestendige tussenlaag, die als een stootlaag, werkt, met maximaal een dikte van 0,1 mm, een smeltpunt groter dan 1000°C en een uitrekking bij breuk-belasting groter dan 10%, is aangebracht.This object is achieved by the present invention with a column-shaped casting roller, which is characterized in that between a raw material of the roller 25 and the friction-resistant and anti-corrosion resistant protective layer, a ductile and also anti-corrosion resistant layer, which acts as a bump layer, with a maximum thickness of 0.1 mm, a melting point greater than 1000 ° C and an elongation at break load greater than 10% is provided.
De tussenlaag kan uit nikkel of uit een nikkellegering bestaan.The intermediate layer can be made of nickel or a nickel alloy.
30 Het is voordelig dat de tussenlaag electrolytisch is opgebracht en de beschermlaag op de tussenlaag is gesinterd.It is advantageous that the intermediate layer is applied electrolytically and the protective layer is sintered on the intermediate layer.
De kolomvormige gietwals volgens de onderhavige uitvinding verhindert door de duktiele tussenlaag ook bij sterke buigspanningen het binnendringen van corrosieve media in de grondstof.The columnar casting roller according to the present invention prevents the penetration of corrosive media into the raw material by the ductile intermediate layer, even under strong bending stresses.
35 Hierdoor wordt een kolomvormige gietwals vervaardigd, die zowel cor- 7904930 y» 1 -2- 20788/JD/tj rosiebestendig is als ook een slijtvast oppervlak heeft. Ook bij het optreden van spanningsbreuken op de beschermlaag worden deze alleen tot de beschermlaag beperkt.This produces a columnar casting roller, which is both corrosion resistant and has a wear-resistant surface. Even when stress breaks occur on the protective layer, these are only limited to the protective layer.
In de bijgevoegde tekening is een .koelbare kolomvormige giet-5 wals volgens de onderhavige uitvinding met een beschermlaag bestaande uit • meerdere lagen schematisch voorgesteld.In the accompanying drawing, a coolable columnar casting roll according to the present invention with a protective layer consisting of several layers is schematically shown.
In deze tekening is de grondstof 1 van de wals van een op de duktiele tussenlaag 3 op gesinterde beschermlaag 2 voorzien.In this drawing, the raw material 1 of the roller is provided with a protective layer 2 on the ductile intermediate layer 3 on the sintered protective layer.
De in de tekening voorgestelde wals is van binnen gekoeld, waarbij 10 overeenkomstige koelkanalen en toe- respectievelijk afvoerkanalen voor het koelmedium aanwezig zijn. Een verdere verklaring van deze (bekende) constructie lijkt ons overbodig.The roller shown in the drawing is cooled internally, wherein corresponding cooling channels and supply or discharge channels for the cooling medium are provided. A further explanation of this (known) construction seems unnecessary to us.
