Definitions
- the present invention relates to the casting of metals into fusion, and more particularly to the vertical continuous casting of parts of metal, in particular of tubes, of cast iron. Although it applies to casting of different types of metal parts, it is particularly advantageous for casting thin cast iron tubes.
- thin tubes applies to a tube with a low thickness / diameter ratio, less than 10 percent, rather than the thickness considered in isolation.
- the invention relates more precisely to a casting machine vertical continuous, according to the preamble of claim 1, which is based on WO-A-94/26 444, along a vertical axis of extraction, of cast iron tubes, comprising a die block aligned along the vertical extraction axis and a liquid iron supply device feeding the die, machine in which at least one seal is disposed between the outlet of the device supply and entry of the sector.
- the present invention aims to overcome these various drawbacks by proposing a casting machine in which sealing against liquid metal is ensured both in the ramp-up phase and in the constant high temperature operating phase.
- the subject of the invention is a device for clamping a casting table of a vertical continuous casting machine, along an axis vertical extraction, of parts, in particular of tubes, in cast iron, the table casting comprising on the one hand a die block aligned along the vertical axis extraction, and secondly a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the liquid iron supply device and the die block, characterized in that it comprises constant force clamping means, in parallel to the vertical extraction axis, from the die block against the exit of the supply of liquid iron to tighten the seals.
- the invention also relates to a casting table of a vertical continuous casting machine, along a vertical axis (X-X) of extraction, of parts, in particular tubes, of cast iron, the casting table comprising on the one hand, a die block aligned along the vertical axis (X-X) of extraction, and secondly, a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the device for supplying liquid iron and the die block, characterized in that it includes a clamping device as defined above.
- Figure 1 a continuous casting table 1 vertical ascending of parts, in particular of T tubes, in cast iron.
- This table casting includes a device 3 for supplying liquid iron and a die block 5 powered by its lower end by this supply device 3.
- the tube T is extracted from the die block 5 by non-extracting means represented, upwards, along the vertical X-X extraction axis.
- the meaning of the extraction force is represented by an arrow F.
- the device 3 for supplying liquid iron is placed on a chassis 6 and secured against lateral and vertical displacement thereon by vertical tie rods 7 and horizontal crosspieces 8. It includes a siphon 9 in the shape of a U made of a single piece of molded refractory concrete.
- This siphon 9 includes a liquid iron supply channel 10 formed by a vertical downward portion 10A of entry of the molten iron, a horizontal part (not visible in the figures) and a vertical part 10B liquid iron outlet, directed upwards.
- a base heater 11 is interposed between the die block 5 and the outlet of the siphon 9. Sealing of molten metal is ensured by two seals annulars 12A and 12B, a first 12A disposed between the outlet of the siphon 9 and the underside of the heating base 11, and a second 12B disposed between the upper face of the heating base 11 and the lower face of the die block 5.
- the siphon 9 and the heating base 11 are surrounded a carcass 13 in the thickness of which are wound windings inductors 14. These inductor windings 14 are supplied with current electric by an external current generator not shown for maintain molten iron by induction heating.
- the die block 5 is fixedly mounted in a retractable support 15 tray-shaped.
- This die block includes a cooling block 17 connected to a coolant circuit by 17A inlet pipes and output 17B.
- Block 17 has an extension on its upper face of reduced diameter. It is received in a conjugate housing 15A of the support 15 with vertical axis Y-Y and is fixed to it by means of a crown of axial screws 15B ( Figure 2).
- the relative position of the support 15 relative to the chassis 6 is determined by two columns 18 directed downwards, fixed to the support 15 diametrically opposite with respect to the die block 5, as the shows figure 2.
- figure 3 shows that each baluster 18 is guided in an associated ball bushing 19 which is fixed to the chassis 6.
- the relative position of the support 15 relative to the chassis 6 and therefore the relative position of the die block 5 with respect to the chassis 6, are precisely defined in a plane perpendicular to the vertical axis X-X extraction, while the support-chassis distance can be adjusted parallel to the X-X axis.
- each cylinder 21 has a rod 22 of which the free end 23 is fixed by a pin 24 in a clevis 25 integral of the chassis 6.
- Each pin 24 is stopped in the yoke 25 by pins (not shown) so that the support 15 can easily be disassembled from the chassis 6.
- the body 21A of the jacks 21 is fixed by a flange 21B on the upper face of the plate 15 so as to be out of reach of the field induction generated by the inductor windings 14.
- each fluid cylinder 21 is connected by a pipe 26, 27 to a common pipe 29.
- This pipe common 29 is connected to a hydraulic unit 31 for regulating the clamping force of each cylinder, shown schematically.
- this hydraulic unit is also mounted on the chassis 6.
- the clamping force exerted on the seals 12A and 12B corresponds to the clamping force exerted by the jacks 21 to pull the yokes 25 in the direction of the support 15. Thanks to the fact that two cylinders connected to the hydraulic unit 31 by a common pipe 29, the applied clamping force is identical for each cylinder. In addition, once regulated, it is constant despite expansion phenomena which occur at the level of the heating base 11, and despite the phenomena of creep of the joints and adhesion of the tube T to the die, this thanks to the principle hydraulic operation.
- the clamping arrangement by hydraulic cylinders also acts as a "safety fuse". Indeed, when the extraction force of the tube T becomes greater than the force applied by the jacks, the elements of the die block tend to dissociate in the direction of extraction of the tube T. This results in loosening of the seals and a leakage of the liquid metal towards outside, and the machine stops without damage for the installation of tube production.
