Abstract

En for mellomstøpssveising av to skinneender (1,2) bestemt støpeform består av to formhalvdeler som overdekker skinneendene i området for sveisefugen (4) sideveis og symmetrisk under tildannelse av formvegger, hvorved det i formveggene er tildannet et system av fotstigere (17), en hodestiger (24) og hodesidestigere (25). Den over skinnehodet forløpende hodestiger (24) oppviser en i retning av skinnehodet (8) konisk tilsmalnende konfigurasjon og de på begge sider av skinnehodet (8) anordnede hodesidestigere (24) står i gjennomgående forbindelse med fotstigerne (17). Hodesidestigeme (25) er anordnet på en slik måte at deres tverrsnittsflate på under- sidene grenser mot en nedre kant av hodeflankene (14) av skinneholdet (8) og forløper oppover fra dertne kant. Idet innmunningstverrsnittet av hodestigerne (25) til støperommet er dimensjonert under hensyntagen til tykkelsen av skinnesteget (7) i henhold til 0,6 hL < A < 3,75 hL, hvor- ved h er høyden av skinnehodet, L er bredden av sveisefugen og A er flaten av innmun- ningstverrsnittet, kan en lunkerdannelse, særlig i det kritiske overgangsområdet mellom skinnesteg (7) og skinnehodet (8), undertrykkes på virksom måte.
