Abstract (en)

Holding fixture for inductive heating of billets of metal alloys having thixotropic properties and holding and transporting of the billets until casting is in the form of a bowl with a trough-shaped body and a wall at each end. At least the body is of a high m. pt. metal. Pref. the cross section of the trough is formed by a part circle or part oval with vertical or slightly diverging walls, or the body cross section is tubular, such that the cross section describes a part circle with a central angle of 120 to 210 deg., w.r.t. 360 deg. for the whole tubular cross section. Body and one or both end walls consists of metal from the series of metals contg. Fe and C, pref. steel, stainless steel. 'Thermax' steel, hot-work steel, or metals of the series Ta, Nb, V, W, Ti or their alloys. One or both end walls can consist of or contain a ceramic material pref. Al2O3, Al2O4, BN, SiC, Si3N4, MgO, TiO, ZrO2, stabilised, partic. yttria-stabilised ZrO2, glasses or refractory cements.
