  • Patent number: 10799949
    Abstract: Slide closure unit on the spout of a metallurgical vessel, preferably a copper-anode furnace, includes a housing in which refractory closure plates, as well as at least one connecting refractory inner casing, are arranged. A removable induction heater is provided, having at least one induction coil surrounding the refractory inner casing outside of the housing. In this way, it is possible to constantly keep the melt located in the outlet channel of the spout sufficiently warm so that it does not freeze before and/or during the pouring of the melt, or that any frozen metal and/or slag can be melted in the spout.

  • Patent number: 10330387
    Abstract: To improve the position of a cylindrical ceramic hollow body the invention relates to a securing device for use with a gas purging brick, where the securing device has the following characteristics in its operational position: A base body which, with its bottom and a circumferential wall, defines a cylindrical space with a corresponding central longitudinal axis, the bottom features an opening whose longitudinal axis aligns with the central longitudinal axis the bottom features a ring-shaped channel which extends concentrically around the opening. at least an inner wall of the channel which is adjacent to the opening consists of a material which is plastically ductile under the application of pressure, a ring-shaped compact whose radial wall cross-section increases in size upwards from a lower free end, so that the inner wall of the channel deforms plastically, thereby reducing the cross section of the opening, after the compact is pressed into the channel.

  • Patent number: 9863708
    Abstract: Refractory ceramic gas purging element, comprising: a refractory ceramic body, a chamber is arranged at the first end (10u) of the refractory ceramic body (10), which chamber extends over at least 50% of the cross section of the refractory ceramic body at its first end, a gas feeding line enters into said chamber, at a distance to said refractory ceramic body, at a section towards the refractory ceramic body the chamber is at least partially permeable to gas, the chamber comprises at least one plate, which is freely moveable in an axial direction of the gas purging element between a first end position and a second end position, the plate is dimensioned, shaped and placed in the chamber such that a gas flow from the gas feeding line through said chamber up to the first end is even secured when the plate is in its second end position.
