Definitions

  • ABSTRACT A de-slagging apparatus having a longitudinally adjustable column vertically positioned in a stand, an arm extending transversally to the longitudinal axis of the column and arranged at the upper end thereof so as to be rotatable about the column axis, a slag skimmer attached to one end of the arm, a horizontal guide mounted on the column and longitudinally slidably supporting the arm and a mechanism for moving the arm in its guide, whereby the slag skimmer travels along the surface of a melt for removing the slag therefrom.
  • the apparatus ac- Thi i v nti r l t t an apparatus f removing 5 cording to the invention essentially comprises a stand slag from casting ladles or the like and is of the type that has a column which is arranged vertically in a stand and which may be adjusted and immobilized in the direction of its length by a power mechanism.
  • the .column further has, at its upper terminal portion, an 1 arm which is movable in a direction transversal to the longitudinal axis of the column and which carries a slag skimmer at one end.
  • the other end of the arm may be manually engaged to pivot the arm about the longitudinal axis of the column.
  • the displaceable arm which carries the slag skimmer is articulated at the upper terminus of the column for a manually effected pivotal motion about a horizontal axis.
  • Apparatuses of the afore-outlined type have the disadvantage that, during the de-slagging of the melt in the casting ladle which is suspended from a crane hook and is placed in an inclined position by the crane, an immersion of the slag skimmer that remains uniform during the entire de-slagging operation is achieved only purely accidentally and further, in case the slag skimmer encounters slag chunks adhering to the casting ladle, the arm carrying the slag skimmer often deviates from its preselected direction of displacement.
  • a horizontally extending guide which is coextensive with the arm and which serves as a support therefor.
  • the immersion depth of the slag skimmer is necessarily maintained at the preselected value as the slag skimmer is moved across the melt towards the spout of the inclined ladle.
  • a power means such as a pneumatic motor or a brake motor (only symbolically shown in FIG. 4), the output shaft 7a of which carries a sprocket wheel 7.
  • the latter meshes with a taut chain 9 which extends along and within the arm 4 and which, at its ends, is secured to terminal portions of the arm 4.
  • the chain 9 is guided by deflecting sprockets 8.
  • the vertically movable column 2 which includes four upright positioned angle bars 2a, is disposed in a space formed of four vertical angle bars 12 affixed to and extending from a base plate 1 1 of the stand 1.
  • each of its angle bars 2a carries, at its lower end, a roller 10 cooperating with the adjacent angle iron 12.
  • a vertical excursion of a magnitude b may be accomplished with the column 2. It is further seen that this arrangement ensures that the column 2 is, with respect to the supporting stand 1, movable solely in its axial direction.
  • the upper end portion of the column 2 carries bearings 14 for the rotary support of a pin 15 extending from the guide 3.
  • a brake drum 16 which cooperates with brake shoes 17 supported on the column 2.
  • the latter may be lifted off the brake drum 16 by the linkage 18 actuated by pneumatic power cylinders (not shown), while the brake shoes 17 may be applied by a spring indicated at 18a.
  • a pneumatic power mechanism instead of the spring means for applying the brake shoes 17.
  • the power mechanism used for releasing the brake shoes 17 is connected to the linkage 18 at 18b.
  • the arm 4 has, substantially along its entire length, external support faces which are in rolling engagement with support rollers 24 rotatably mounted on the guide 3, as it may be well obtained by considering FIGS. 1, 4 and 5 together.
  • the maximum possible horizontal stroke a of the arm 4 is determined by the length of the support faces of the arm 4 and is independent from the length of the guide 3 itself.
  • the controls of the preferably pneumatically operable brake 16, 17, 18, the pneumatic power cylinders 19 and 20 connected with the column 2 and the setting motor for the arm 4 are arranged on the handles 6.
  • the handle to be manipulated by the operators left hand carries the brake control, while the other handle accommodates the controls for the height adjustment of column 2 and the longitudinal movements of the arm 4.
  • These controls are further judiciously so arranged that they simultaneously permit a selective alteration of the operational speeds of the individual setting mechanisms.
  • table 30, in the first place a greater displaceability of the arm 4 is ensured, and, in the second place, the operator is always positioned approximately at the level of the melt, whereby favorable conditions are provided for the observation and control of the slag removing process.
  • a casting ladle 26 which is suspended from a liftable and lowerable mechanism 27 associated with a crane (not shown). With the aid of this mechanism the casting ladle 26 is tilted into a position which is favorable for performing the de-slagging operation.
  • Below the spout 28 of the casting ladle there is disposed a receptacle 29 for receiving the slag removed from the melt by means of the deslagging apparatus.
  • the stand 1 is designed to travel on rails 31. It is also feasible to design the stand 1 as a trackless mobile structure. In this manner a very economical Working arrangement can be accomplished, utilizing a plurality of casting ladles 26.
  • the ladle 26 is supported by a stand 32 which includes a cradle member 34 receiving the casting ladle 26.
  • the cradle member 34 is articulated with a horizontal pin 33 to a base 33a and it is steplessly adjustable in its inclination by means of a hydraulic power cylinder 35.
  • the particular stand structure 32 eliminates the necessity of using a crane for supporting and tilting the casting ladle during the entire de-slagging operation.
  • the crane may be used to perform other tasks.
  • samplings and temperature measurements may be performed with the de-slagging apparatus without the aid of a crane.
  • travelling frame 1 By virtue of the travelling frame 1, it is possible to dispose, next to the de-slagging apparatus, a plurality (e. g., three) of stations where the casting ladles 26 may be positioned. It is also feasible to provide circular rails for the stand 1 in which case the casting ladle supports are arranged in a circular array.
  • a de-slagging apparatus comprising in combination:
  • a de-slagging apparatus as defined in claim 1, including support means for mounting said arm on, and rotatably about the longitudinal axis of, said column; and selectively operable brake means for immobilizing said arm to prevent its rotary displacement with respect to said axis.
  • a de-slagging apparatus as defined in claim 1, including means cooperating with said stand and with said column for providing solely for an axial displacement of said column; power cylinder means engaging said column for the vertical displacement thereof; and means for rotatably supporting said guide on and about the axis of, said column.
  • a de-slagging apparatus as defined in claim 1, wherein said means for moving said arm along its length dimension includes a motor means; a sprocket wheel mounted for rotation on said guide and driven by said motor means; and a chain driven by said sprocket, said chain extending along said arm and being attached to said two ends thereof.
  • a de-slagging apparatus as defined in claim 1, including a table on which said column is mounted; means for adjusting the height of said table; a platform supported on said table adjacent said column for receiving an operator; and manually operable means arranged on the end of said arm remote from said slag skimmer for controlling the operation of the apparatus.
  • a de-slagging apparatus as defined in claim 1, including an additional stand supporting said column; and a ladle supporting stand mounted on said additional stand within the range of said slag skimmer.
  • a de-slagging apparatus as defined in claim 4, wherein said arm is hollow along its length and said chain extends at least partially within said arm.
  • a de-slagging apparatus as defined in claim 1, wherein said arm has a support surface extending substantially along the entire length of said arm; said arm being arranged coextensively with said guide and being supported thereby by direct engagement of said guide with said support surface.
  • a de-slagging apparatus comprising in combination:
