Definitions

  • the invention relates to the adjustment of the flow rate of molten metal contained in a continuous casting distributor, or basket, and flowing in a metal solidification mold.
  • the action on the control member can be manual, but it is also known to automate it by a device for detecting the filling level of the mold.
  • Such an adjustment circuit, in closed mouth can be produced with the use of radioactive sources which are suitably arranged but which have a certain number of drawbacks in use.
  • a closed loop circuit based on the detection of radiation emitted by the liquid metal of the ingot mold, and experimented industrially on the continuous casting installation of the applicant together with the mechanical control object of the invention, eliminates these drawbacks, presents perfectly reliable operation, and ensures remarkable level stability in the mold. This result is obtained even in the case where pipes are used to protect the jet of liquid metal flowing between the distributor and the ingot mold, together with synthetic slags for covering the meniscus of liquid metal in the ingot mold.
  • the object of the invention is to improve the reliability of the complete installation, on the one hand by not unnecessarily exposing a delicate active member in the immediate vicinity of the casting, and on the other hand by ensuring that if however an incident occurs on a dispatcher can be quickly evacuated.
  • crank pin (9) with crank pin (10), the pinion (8), the support (7), the rack (6), the cross-member (5) and the stopper (4) constitute a mechanism (11) called hereinafter. coiled post.
  • a proximity control station 12 which comprises a first lever 13 and a second lever 14 both articulated on the same fixed axis 15, these two levers being able to be coupled together or decoupled to will by the introduction or removal of a spindle 16.
  • a control rod 17 of adjustable length is articulated at one end at a point 18 of the lever 13 while its other end 19, in the form of a fork with lateral opening, can be hooked on the crank pin 10 of the crank 9.
  • the end 20 of the second lever 14 is joined by a connecting rod 21 to a sliding device 22 actuated by a ball control under sheath 23, from a console remote control 24, in which the other end of the ball control 23 is fixed to another sliding device 25.
  • the latter is coupled by another link 26 to a third lever 27 articulated at a fixed point 28 at the same time as 'a fourth lever 29.
  • the third lever 27 can be actuated itself by means of a lateral articulation 30, and by means of a link 31, from a manual control lever 32 pivoting around a fixed axis 33 and containing the articulation 34 of the other end of the link 31.
  • a counterweight 35 acts on the lever 32 for manual control.
  • the device is advantageously completed by an emergency control constituted by a lever 40 which is fixed in the extension of the first lever 13.
  • the casting operation can begin with a manual action on the control 32 which freely ensures the transmission. of movement, the clutch 39 being at this time not excited.
  • the actuator 37 provides consequently the control of the movement of the stopper 4 at the same time as the movement of the lever 32.
  • control desk 24 with its delicate parts, in particular the electric actuator, the manual control and the counterweight is located at a distance from the molten metal. This results in greater safety for personnel during start-up and also better conservation of the equipment.
