<p>The device for melting metals, comprises a crucible (1), a hollow cylindrical guide plate (9) coaxially surrounding the crucible, so that an annular gap for a cooling fluid is formed between the external wall of the crucible and the inner wall of the guide plate, and a cooling pot (2) for the reception of the crucible. The guide plate comprises two semi-cylindrical bowls, which are detachably connected with one another at their longitudinal edges. Spacers are arranged in the annular gap and determine the width of the annular gap. The spacers are fastened to the bowls. The device for melting metals, comprises a crucible (1), a hollow cylindrical guide plate (9) coaxially surrounding the crucible, so that an annular gap for a cooling fluid is formed between the external wall of the crucible and the inner wall of the guide plate, and a cooling pot (2) for the reception of the crucible. The guide plate comprises two semi-cylindrical bowls, which are detachably connected with one another at their longitudinal edges. Spacers are arranged in the annular gap and determine the width of the annular gap. The spacers are fastened to the bowls and are formed by short round bars, which are arranged parallel to the longitudinal axis of the guide plate. The guide plate tightly fits with its top edge to a ring, which is arranged within the upper region of the crucible and whose interior edge maintains a distance for the external wall of the crucible. The ring is fastened below and in a distance to a flange (3) formed at the top edge of the crucible. The cooling pot comprises a cylindrical cover and a base. The flange is placed on the top edge of the cooling pot so that the cooling pot is closed and comprises a water inlet connecting piece (4) and a water outlet piece near the surface. The base of the crucible consists of two layers, between which fluid channels are formed, extend into the lateral surface of the crucible and are fluidically connected with the water inlet connecting piece. An intermediate pot is arranged between the guide plate and the cooling pot, which lies closely with its top edge sealed at the ring. The base of the cooling pot comprises an opening, by which a pipe is passed through and forms a section of the fluid connection. The ring is provided with apertures between its lower and top surfaces, which extend into a further annular gap between the guide plate and the intermediate pot.</p> |
