Definitions

  • the invention concerns a converter consisting of a metal shell with a lining of refractory bricks disposed inside, said shell being formed of a cylindrical part with a bottom and a part narrowing towards an eccentrically located mouth.
  • a converter of this kind is commonly known.
  • the cylindrical part narrows gradually towards the mouth.
  • the converter is tilted, and the slag and the metal are poured out via the mouth or a special pouring spout and for taking a sample the converter is tilted backward.
  • the metal bath in the conventional converters in the tilted position is shallow. This entails the drawback that metal and slag are mixed, while the depth of the bath is frequently insuflicient for proper sampling.
  • the object of the invention is to obviate this drawback.
  • the transitional zone which extends from the uppermost layer of bricks of the exclusively cylindrical converter part to the lowermost layer of bricks of the exclusively narrowing part, is angular at least in the region which is diametrically opposed to the side containing the pouring spout.
  • the narrowing part of the converter may further be conical.
  • the axis of the conical part may be substantially parallel to the axis of the cylindrical part.
  • the converter is tilted in such a way that the pouring spout is pivoted upward until sufiicient metal is present at the level of the transitional zone between the cylindrical and the narrowing part to enable sampling. Because the axes of the cone and the cylindrical part are parallel, the advantage of the greater depth during tapping is also obtained on the other side of the converter, where sampling takes place.
  • the above-described novel converter configuration serves to also simplify the fabrication of the lining.
  • the number of moulds for the bricks is reduced, and the bricks can be more easily recognized by the brick-layers.
  • the axis of the cylindrical part may pass through the mouth. Owing to this measure it is possible to move a lance concentrically towards the metal bath, while through the eccentricity ol the mouth escaping gases can be discharged beside the lance into a flue.
  • the converter consists essentially of a metal shell with a cylindrical part 1, a bottom 2, and a conical part 3, the axis 4 of the cylindrical part being parallel to the axis 5 of the conical part.
  • a pouring spout 6 In the lowermost portion of the transitional zone between the cylindrical and the conical part has been provided a pouring spout 6.
  • the whole lining is composed of horizontal layers of refractory bricks, in such a way that the refractory bricks of the same layer in the transitional zone between the cylindrical and the conical part can at once he fitted against each other. Because the axes of the cylindrical and the conical part are parallel and the layers of refractory bricks are perpendicular to said axes, the layers of bricks intersect the conical surface along circles, in consequence of which only one brick mould is required for each layer.
  • a conical top portion adjacent the other end of the body portion, narrowing away from said body portion, said top portion defining a cone axis, said cone axis being parallel to, and spaced a given distance from, the cylinder axis, the intersection between the body and top portions being a sharply defined angle, said cone having an opening at its narrower end which is substantially symmetrical with respect to the cone axis, said given distance being such that the cylinder axis passes through said opening;
  • the lining of the cylindrical and conical portions is composed of layers of refiractory bricks, said layers being in planes perpendicular to said axes, the shape of the converter being such that in the vicinity of the intersection between the top portion and the body portion, the bricks are fitted together without reshaping.
