Definitions

  • the present invention relates to the handling of a protective tube for a pouring stream, with a view to placing said tube under the orifice of a container, such as a ladle containing molten metal.
  • This tube is intended to immerse in the metal. fusion contained in another container, such as a pouring distributor placed under the preceding container.
  • the handling device having all the characteristics of the preamble of claim 1 described in document FR-A-2,399,295 and which comprises a carriage movable along a horizontal track, a vertical barrel integral with said carriage and a carrying arm supported by said barrel and provided with means for gripping the protective tube has a limited radius of action and has only one degree of freedom in a horizontal plane.
  • the main object of the invention is to solve this problem by limiting human intervention to the sole final positioning of the tube and by making it possible to automate the various operations of the handling device.
  • a device for handling a tube protecting a casting jet in particular for applying said tube under the orifice of a molten metal casting ladle, or the '' removing therefrom, comprising a first carriage movable along a horizontal track, a vertical barrel integral with said carriage, an arm carrying the jet protection tube supported by said barrel and means for gripping the tube by the carrying arm, characterized in that it further comprises means for controlling the rotation of said barrel about its longitudinal axis, a second carriage movable vertically along the barrel under the action of drive means and a counterweight holding the second carriage in position when the drive means of said carriage have ceased to act, and in that the carrying arm is articulated to the second carriage by means of a connecting rod.
  • the connecting rod is provided with a locking system in position, said system being rendered inoperative after application of the tube under the ladle.
  • the locking system consists of two roller support arms arranged on either side of the connecting rod and controlled by jacks.
  • the support arm is mounted to rotate about its longitudinal axis, the drive means of said arm being mounted at the end of the latter, opposite to that which carries the tube.
  • the means for gripping the tube by the support arm consist of clamps, the means for driving said clamps being mounted at the end of the arm opposite to them.
  • the means for controlling the rotation of the barrel about its longitudinal axis comprise an orientation ring connecting the barrel to the first carriage.
  • the drive means of the second carriage in the vertical direction comprise a chain, one end of which is fixed to said carriage and the other to the counterweight, a return wheel of said chain and a geared motor group, the latter controlling the rotation of the idler wheel via a brake and a clutch.
  • the first carriage and all of the elements which are attached to it are mounted suspended.
  • the reference numeral 1 designates the tube for protecting a casting jet resting under a first container, such as a ladle 2.
  • This tube is intended to immerse in the molten metal collected by a second container, such as a continuous casting distributor 3, placed under the casting ladle 2.
  • a drawer system 4 makes it possible, on request, to authorize the flow or to interrupt it.
  • the tube 1 is held by a system of clamps 5 mounted at the end of a support arm 6.
  • a system of clamps 5 mounted at the end of a support arm 6.
  • it is essential to provide a certain number of movements: horizontal translation of the arm carrier 6, rotation of said carrier arm about a vertical axis, vertical translation of said carrier arm and possibly rotation of said carrier arm about its longitudinal axis.
  • It is also necessary to provide a means of controlling the clamp system 5 and degrees of freedom to collect the variations in position of the ladle 2, allow the opening or closing of the drawer system 4, and ensure the correct positioning of the tube 1 under the casting jet, more precisely under the nozzle 7 of the casting ladle 2.
  • the carrying arm 6, by means of a support box 8 and a connecting rod 19, is made integral with a carriage 9 vertically movable along a barrel 10 capable of being driven in rotation around its axis by an orientation ring 11, which is integral with a carriage 12, horizontally movable along a suspended track 13.
  • This mechanically welded construction carriage is a self-propelled carriage mounted on rollers, such as 14, rolling on the track 13.
  • the movement is controlled by a geared motor group 15 mounted on one end of the carriage 12 and which rotates the rollers 14 located at the other end of said carriage by a chain transmission 16.
  • the rotation of the support arm 6 around the axis of the barrel 10 is controlled by a geared motor group 17 secured to the carriage 12, by means of the slewing ring 11 interposed between the barrel 10 and the carriage 12.
  • the barrel 10 is provided with rails for guiding the vertical movement of the carriage 9 which will be discussed later.
  • a connecting rod 19 fixed to the carriage 9 supports the support box assembly 8 - carrier arm 6.
  • the assembly is locked, during handling, by means of two roller-carrying arms such as 20, which position the connecting rod 19 and therefore the support 8 and the support arm 6 in a predetermined position.
  • the control of the arms 20 is ensured by pneumatic cylinders such as 21.
  • the assembly being unlocked, during casting, two degrees of freedom are obtained for the movement of the drawer system 4, without any reaction on the other elements of the device. handling.
  • the movement is controlled by a geared motor unit 25 integral with the barrel 10 by means of a brake 26 and a clutch 27.
  • a geared motor unit 25 integral with the barrel 10 by means of a brake 26 and a clutch 27.
  • the rotation of the carrier arm 6 about its longitudinal axis is controlled by a geared motor group 28 via a wheel 29 and a chain 30.
  • the arm 6 is mounted on two rolling bearings, such as 31 , carried by the support box 8.
  • the control is provided with an angular play of ⁇ 5 ° relative to the vertical position of the tube 1. This results in an additional degree of freedom.
  • the invention therefore covers, in addition to the example illustrated, its various possible alternative embodiments.
