Definitions
- the present invention relates to the casting of metals into fusion, and more particularly to the vertical upward continuous casting of metal parts, in particular of tubes, of cast iron. Although it applies to the casting of different types of metal parts, it is particularly advantageous for casting thin cast iron tubes.
- the expression “tubes thin” 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 positioning device, with respect to a vertical extraction axis, of a die block of a machine continuous vertical upward casting of cast iron tubes.
- a machine casting system includes a die block and a liquid iron supply device which feeds the die block through the lower end thereof.
- a device of supply is for example described in document FR-A-2 705 259 at name of the Applicant.
- This liquid iron supply device has a U-shaped siphon block made of molded refractory concrete and on the outlet of which the die block rests.
- such a siphon block is progressively worn and / or consumed by molten iron which is in contact with it during the process continuous casting.
- the solidification of the cast iron bursts the siphon block.
- this siphon block must be replaced in its as soon as a certain number of tubes have been poured, i.e. each stop.
- siphon block is a relatively massive, and given its location on the casting table of a casting machine in a tube production facility, replacement on site the siphon block is very difficult, if not impossible. It is why, it is necessary to remove the entire casting table from the installation of production of tubes in order to be able to disassemble and be able to proceed easily to replace the siphon.
- the alignment of the die with the vertical axis of extraction of the tubes poses a problem. Indeed, the die block must be aligned precisely along the vertical extraction axis so that the tube manufacturing facility can function properly. Now, the casting table having been entirely dismantled, this alignment by relation to the axis of extraction of the die block is difficult and takes a lot of time, particularly because of the uncertain geometry of the material parts refractory used.
- the present invention aims to solve this positioning problem of the die block with respect to the vertical extraction axis by proposing a positioning device for a die block which enables a quick and precise alignment between the die block and the vertical extraction axis so reduce the duration of tube manufacturing interruptions.
- the invention relates to a positioning device, relative to a vertical axis of extraction, of a die block of a table casting of an ascending vertical continuous casting machine for parts, in particular of tubes, in cast iron, machine with which the die block is supplied, by its lower end, by means of a liquid iron supply device, and is supported on it, positioning device characterized in that it includes a retractable support in which the die block is fixed, a movable frame on which the cast iron delivery device is placed liquid, means for relative positioning of the support relative to the chassis, locking members intended to block the relative position between the support and the chassis so that the support and the chassis form a monobloc assembly, a base arranged in a predetermined manner with respect to the vertical extraction axis and intended to carry the monobloc assembly, and means for aligning the axis of the die block and the vertical extraction axis.
- the invention also relates to a casting table of a vertical upward continuous casting machine for parts, in particular for tubes, in cast iron, casting table from which the die block is supplied, by its lower end, by means of a liquid iron supply device, and is supported on it, characterized in that it comprises a device for positioning as defined above.
- FIG. 1 a casting table 1 of a vertical upward continuous casting machine for parts, in particular for T tubes, cast iron.
- This table includes a device 3 for supplying cast iron liquid and a die block 5 fed, by its lower end, by this supply device 3.
- the tube T is extracted from the die block 5 by means not shown, upwards, along the vertical X-X extraction axis.
- the direction 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 comprises a supply channel 10 made of cast iron 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 of liquid iron outlet, directed upwards.
- a heating base 11 is interposed between the die block 5 and the outlet of the siphon 9. Metal tightness in fusion is ensured by two annular seals 12A and 12B, one first 12A disposed between the outlet of the siphon 9 and the heating base 11, and a second 12B disposed between the heating base 11 and 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 5 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.
- 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 chassis 6 rests on a fixed base 40 by four support points.
- the chassis 6 has on its underside two crosspieces horizontal support 42 of square section. As seen in the figure 2, these cross members 42 are longer than the width of the chassis 6 and protrude laterally from this chassis.
- the sleepers 42 have at each of their end zones, in a wall 44 which faces the base 40, a tapped hole 45.
- a support screw 46 is screwed into the bore 45 and constitutes therewith a cylinder 47 for adjusting the horizontality of the chassis. Screw 46 is secured against untimely rotation by a lock nut 48. It is then understood that the chassis rests by the lower ends of the four screws 46 on the base 40.
- the frame 6 comprises in addition, on its underside, a horizontal crosspiece 56 for centering square section.
- this crosspiece 56 for centering has a wall 58 facing the base 40, in which a centering hole 60.
- This centering hole 60 is centered relative to the axis Y-Y of the die block 5.
- a protective cover 62 is disposed above the hole centering 60.
- This centering hole 60 cooperates without significant play with a pin of centering 64 integral with the base 40.
- the base 40 is arranged so that the vertical axis of the centering pin 64 is aligned with the X-X extraction axis of the means of extraction.
- this centering pin 64 allows a point to coincide with the axis of revolution Y-Y of the die block 5 with a point on the vertical axis of extraction X-X of the extraction means.
- the chassis 6 has at its end located on the right in referring to FIG. 1, a horizontal cross-member 70 for additional centering square section.
- This cross 70 has in its wall 72 in look of the base 40, in its center, a centering groove 74 which cooperates with an additional centering pin 76 secured to the base 40.
- This groove 74 is also protected by a protective cover against involuntary filling.
- the chassis 6 further comprises on its underside horizontal cross members 80, 82 and 84 of square section intended to join the chassis 6 on the base 40.
- the cross members 80, 82 and 70 each have from their lateral ends holes intended to receive screws which are fixed in the base 40 to stiffen the chassis / base assembly after the positioning of the chassis 6 relative to the base 40 is achieved.
- the space between sleepers 56 and 82 as well as that between cross members 82 and 84 are provided for forks of a pallet truck in order to ability to easily move frame 6 with casting table 1 to replace the siphon 9 of the device 3 for supplying cast iron liquid.
- the siphon 9 of the device 3 of liquid iron supply must be changed regularly.
- we unscrew the lateral fixing screws in the crosspieces 80, 82 and 70 and rides the chassis 6 by a pallet truck to move the assembly to a another place to dismantle the entire casting table 1.
- the fixing pins 24 are released from the yokes 25, which allows lift the assembly consisting of support 15 with the die block, balusters 18 and jacks 21. It then suffices to dismantle the tie rods 7 with the crosspieces 8 to be able to replace the used siphon 9.
