    摘要: A device for coupling a blow lance with a header is disclosed, in which the force required for producing a sealing joint between the header (2) and the lance (4) is exerted by a cooling fluid and/or a blowing fluid. In a preferred embodiment, said cooling fluid and/or blowing fluid acts via a pressure surface (32) on the joint between the header (2) and the lance (4), the pressure surface being integral with a piston (22) which transmits the pressure to said joint. The lance has preferably a first coupling surface (12), while the header (2) has a second coupling surface (14), and one of said coupling surfaces (12 or 14) is integral with said piston (22).

    摘要: The present invention relates to drives for an automatic lance-changing devices. In accordance with the present invention, the drive effects the coupling of lances used for supplying media by pressing them against a coupling head which, in turn, is accomplished by draw rods which are operated with the aid of lifting spindle movement transmitting screw thread systems. Each draw rod has associated with it its own reduction gear unit which has an integrated lifting spindle system and on which a load cell is mounted. The primary shafts, in alignment with one another, of the two gear units are connected together by a coupling which compensates for axial, radial and angular displacements.

    摘要: An automatic lance changeover device is presented wherein a radially guided ring is axially vertically displaceable by two lifting spindle systems provided on each side of the ring and bears pivotable hooks for receiving the lance and for pressing the latter axially against a sealing surface on the coupling head. The hooks are connected to the stationary coupling head via pivotable connecting rods whose length is alterable, these connecting rods being eccentrically articulated on the support pin of the hooks with the bearing bore at the coupling head end of the connecting rods having a larger diameter than the associated wrist pin. When the ring is axially displaced, the hooks, which have swung out, in a first phase, initially surround the supporting pins on the upper part of the lance as the ring is displaced further, the hooks, without executing any further pivoting movement, pull the lance head into sealing contact with the coupling head.

    摘要: An apparatus is provided for supplying media to a blowing lance, particularly a blowing lance used in the production of steel by a top blowing process. A vertically movable lance carrier comprises a media connection device having a vertical connection surface. Before coupling, the blowing lance is first locked on the lance carrier by a fastening device. The connection device is movable horizontally in guide rails on the lance carrier from a waiting position towards the coupling head of the blowing lance.

    摘要: The invention relates to a distribution chute (100) for a charging device of the rotary pivotal type, e.g. for a shaft furnace. The chute has an upstream mounting head (114) and a chute body (112) having an elongated downstream chute portion (116) with a longitudinal axis (L). It further includes at least two lateral suspensions (130) at the mounting head for mounting the chute to at least two corresponding support flanges of the charging device, the support flanges (140) being pivotable about the pivoting axis (B) in a raising sense (R) for raising the outlet (120) to a radially outer-most charging position and in an opposite lowering sense for lowering the outlet to a radially innermost charging position with respect to the rotational axis. The suspensions (130) define a first and a second tilt points, which define, in turn, a tilt axis (T), about which the weight of the chute exerts torque onto support flanges of the charging device when the chute is mounted. The suspensions are configured in such a way that the ratio of the distance between the tilt axis and the pivoting axis to the distance between the first and second tilt points (which corresponds at least approximatively to the distance between the suspensions) amounts to 0.25 at most. According to the invention, the suspensions (130, 230, 330) are arranged so that an acute angle (a) from the longitudinal axis (L) to a virtual plane (P) through the tilt axis (T) and the center of gravity (G) of the chute has an angular measure in the raising sense (R) that has a small positive or a negligibly negative value.
