Definitions
- the invention relates to a mold tube according to the features in the preamble of claim 1.
- the invention is directed to a method for recalibrating an im Use of the mold tube.
- Mold tubes for continuous casting are known to be used in cooling Water boxes tightly fixed. To withstand the high cooling water pressures, the mold tubes are stiffened at their upper ends so that they retain their shape maintained. In this context, it is particularly with some Double-T-shaped cross-section with "beam-blank” or “dogbone” molds known, in the opposite outer channels at the upper ends Weld wedges so that such mold tubes in the front view then one have largely rectangular cross-section.
- the invention is based on the object, on the one hand to create a mold tube that is perfectly sealed and dimensionally stable in one Water box can be fixed in position, and on the other hand a method for recalibration to introduce a mold tube that was in use, in which the The mold tube can be reworked several times without the reworking lead to sealing problems or damage to the mold material.
- a mold tube at a distance from the upper end face of the tube wall, an outer circumferential groove, in particular rectangular in cross section, is provided. Furthermore, a circumferential shoulder on the mold tube is adjacent to the upper end face generated.
- a stiffening frame which is also on the flange of the water tank supports. The stiffening frame is also sealed against the water tank. Below the stiffening frame are two U-shaped flanges with inner ones Locking webs, which from opposite sides in the circumferential groove on the Grasp the pipe wall. The radial extension of the locking bars is smaller than the depth of the Dimensioned circumferential groove.
- the stiffening frame is on the heel pushed and then with the two U-shaped flanges by screws firmly connected.
- the upper end of the mold tube Sufficiently stabilized against cooling water pressures.
- the lowest is according to claim 2 of the paragraph facing inner edge of the stiffening frame with a recess to accommodate the sealing ring.
- This sealing ring is used when screwing of the stiffening frame with the U-shaped flanges in the corner area of the paragraph pressed and in this way ensures the seal.
- claims 1 and 2 are particularly advantageous in the case of a double T-shaped configured mold tube according to claim 3 applicable, for example in the form of a "beam-blank” - or a “dogbone” mold. Conceivable is also used for billet and bloom formats.
- Restoring the inner mold cavity of a mold tube can be done with all known methods are carried out. However, the is particularly advantageous Restoration of the mold cavity by explosive molding at one in the Mold tube inserted mandrel according to the features of claim 5.
- FIGS Designated double T-shaped cross section.
- Such a mold tube 1 is also called "beam-blank” mold.
- an outer circumferential groove 9 is rectangular in the tube wall 4 Cross section provided.
- the circumferential groove 9 serves to accommodate two U-shaped ones Flanges 10 trained inner locking ridges 11.
- the radial extension the locking webs 11 is smaller than the depth of the circumferential groove 9.
- the corner regions 12 of the flanges 10 are also rounded.
- the stiffening frame 6 is underpinned by holding plates 17 which are connected to the water tank 2 are screwed.
- a seal 21 between the stiffening frame 6 and the water box 2 serves to seal against the overlying Flange 18 of the water box 2. With 19 in Figure 3, the water jacket is designated.
- a Mold tube 1 With a decrease in wall thickness of approximately 0.7 mm per calibration, a Mold tube 1 can be recalibrated about three times.
