 the electroslag remelting of a consumable electrode in a cooled mold having a core disposed therein, the core forming the internal cavity of the ingot being built up on a cooled bottom plate, features, according to the invention, a mold, a core and a bottom plate together with an ingot secured thereon in the process of remelting the consumable electrode, which are given longitudinal motion in relation to each other so that the upper end face of the core is constantly immersed in the molten slag bath.
The mutual motion of the mold, core and bottom plate may be carried into effect either by moving the cooled core upwardly in relation to the stationary mold and bottom plate, or by moving the bottom plate together with the ingot secured thereon downwardly in relation to the core and stationary mold, or, finaly, by moving the mold together with the bottom plate and the ingot secured thereon and being built-up downwardly in relation to the core.
To improve the internal surface of the hollow ingot being made, the core during the remelting process should be given rocking motion.
The device for carrying into effect the proposed method, comprising a cooled mold, a bottom plate and a core for shaping a cavity in the ingot being built-up, according to the invention, is provided with mechanisms for effecting mutual motion of the mold, bottom plate and core in the process of remelting a consumable electrode.
The device is preferably provided with a mechanism for imparting to the cooled core a rocking motion in a longitudinal direction, and a mechanism for imparting to the core reciprocal rotary motion.
The nature of the present invention will further be made more fully apparent from a consideration of the following description of its exemplary embodiments, taken in conjunction with the accompanying drawings. This invention relates to a device for melting ice and snow along the edge of roofs. Ice dams and icicles forming on building roofs near the outer edges, (eaves) or where two pitched surfaces of a roof meet, (valleys) and extending into the roof gutters are a significant source of damage to a building. These ice dams and icicles also create safety hazards. Ice dams form when snow on an inner or middle section of a roof melts and the melt water flows down to the outer section of the roof, where it then refreezes into ice. The heat formed within the building conducts through the roof to melt the snow on the middle portion of the roof. However, the outer edge of the roof
