Abstract

The invention relates to a method for producing a mold tube made of copper or a copper alloy for a strand casting mold. A tube blank is formed on a mandrel by applying a force from the outside, said mandrel determining the inner shape of the mold, and the mandrel is removed from the mold tube (1, 1a) after the shaping process. The force is applied by moving the tube blank relative to a die that surrounds the tube blank. The die has a shaping structure for a cooling profiled section (6, 6a; 7, 7a) on the outer face (5) of the mold tube (1, 1a) so that the cooling profiled section (6, 6a; 7, 7a) is produced by means of the die while the tube blank is being shaped on the mandrel.

Description

Method for the manufacture of Crystallizer tube
Technical field
The feature that the present invention relates to a kind of preamble according to claim 1 is described, be used for the method for Crystallizer tube continuous cast mold, that made by copper or copper alloy.
Background technology
In the prior art tubular crystallizer section bar, that made by copper or copper alloy that is used for the dystectic steel of casting or other metal has been carried out a large amount of descriptions.Generally Crystallizer tube has uniform wall thickness in the cross section of level, and this wall thickness increases along the pipeline direction owing to the internal taper of Crystallizer tube.The coagulating property of internal taper and pipeline and continuous casting parameter are complementary.Heat radiation mainly shows two dimension upward and causes the serious inhomogeneous cooling of steel pipeline.At this, the violent especially shell that demonstrates pipeline in the bight of Crystallizer tube increases (Schalenwachstum) and shrinkage character, and this is because distribute king-sized heat herein owing to the ratio of casting area and film-cooled heat is unequal.Cooling power in the side of Crystallizer tube because the ratio of casting area and film-cooled heat is almost equal less than the cooling power in angular zone.Stay higher hot-fluid simultaneously.This causes comparing the shell that reduces with angular zone and increases.
Because the different cooling ratio of Crystallizer tube inside produces different pipeline shells in the level cross-sectionn and increases.The result produces tension and compression in the pipeline shell.Because the intensity of pipeline shell is also lower after just solidifying, so such stress causes the inside and outside defective of the crackle form in the steel billet easily.The risk that pipeline shell in the crystallizer bottom ruptures also raises.
Therefore try hard to making the Crystallizer tube optimization on the level cross-sectionn uniformly and on the basis of pipeline maximum heat radiation on the whole holdup time in crystallizer.Owing to the rising along with casting speed of the thermic load of Crystallizer tube raises, this point is more important.Therefore must lay siege to best as far as possible cooling, damage to reach the raising Crystallizer tube purpose in service life in order to prevent Crystallizer tube.
As for example introducing among EP 1 792 676 A1, can realize higher heat radiation by additional cooling bath.Cooling bath is being complementary with the heat that need distribute aspect its degree of depth and the layout, and wherein, the angular zone of Crystallizer tube is vacated.Because groove is configured to the recess in the surface, so make groove by machining.
DE 36 15 079 A1 have introduced a kind of method of the continuous cast mold of using for the manufacture of conticaster, and in the method, tubing is passed pattern by the mandrel finishing of inboard and in the outside by drawing, and this pattern is given the crystallizer exterior contour.Can also make crooked crystallizer in this way.
Summary of the invention
The objective of the invention is, a kind of method for the manufacture of Crystallizer tube is provided, utilize this method to make at low cost and have the best Crystallizer tube that dispels the heat.The method of the feature of this purpose by having claim 1 is achieved.
Favourable improvement project of the present invention is the theme of dependent claims.
Method for the manufacture of the Crystallizer tube of being made by copper or copper alloy according to the present invention is set: the effect of mother tube (Vorrohr) power by the outside on the mandrel of the interior shape of determining crystallizer is shaped and again described mandrel is shifted out from Crystallizer tube after forming process.At this pattern is passed in mother tube guiding, this pattern has the stereotyped structure for the cooling contour segment on the outside of Crystallizer tube, thereby makes cooling contour segment by described pattern at mother tube in the process that mandrel is shaped.
Therefore the method according to this invention arranges the chipless processing to the cooling contour segment, and this method is achieved by the special stereotyped structure in the pattern.Utilize the method according to this invention can be than obviously make the cooling contour segment by machining fastlyer and more economical.
Certainly do not get rid of within the scope of the invention and additionally implement machining, in order to carry out local coupling, for example so that groove milling is fixed on water jacket inside by these grooves with Crystallizer tube.Yet basic principle based in the continuous processing method (im Durchlaufverfahren) be shaped to make the method for cooling contour segment by chipless.
In this way, the cooling contour segment can extend to the bottom from the upper end of Crystallizer tube always.Project organization accurately about cold and hot contour segment needs to determine according to the heat of being distributed by tubing during the holdup time in Crystallizer tube.
In addition, heat radiation is by deriving with the outer surface that cooling water is in the Crystallizer tube that contacts.Mathematical method for this reason is: Q=α * A * Δ Τ, and wherein, Q represents hot-fluid, and α represents the crystallizer lateral surface to the thermal conductivity factor of cooling water and Δ Τ represents cooling water temperature along Crystallizer tube during cooling stage and rises.At this, heat and the heat transfer area that need shed are proportional.Make more heat can be dispersed in the environment by utilizing the cooling contour segment to enlarge the outside, namely in the cooling water.Therefore cool off contour segment and cause area to increase, wherein, this area increases to be determined by the structure of pattern.
Preferably by being passed pattern, the mother tube drawing makes the cooling contour segment according to the present invention.Can vacate the angular zone of Crystallizer tube at this, in order to avoid also additionally increase the heat transfer area in this zone.Cooling contour segment itself can be constructed with the rill profile of waveform configuration or be configured to the sawtooth profile.Waveform profiles section or also have the sawtooth contour segment to pass in drawing under the situation of pattern than having for example easier processing of each groove that is spaced apart from each other of rectangular cross section.
Particularly advantageously set within the scope of the invention: the cooling contour segment manufactures the panel height that has in 0.5 to the 5mm scope, wherein, manufacture in 15 to 90 ° scope at the subtended angle between the sawtooth of two adjacency under the situation of sawtooth profile, and wherein, the distance between the rill of two adjacency under the situation of waveform profiles is 1 to 14mm.
Panel height is 0.5mm to 1.5mm in favourable improvement project.Subtended angle is preferably in 45 ° to 60 ° scope.
The method according to this invention can be migrated in the Crystallizer tube of all form known in principle, and they are: cross section is circular, rectangle or foursquare.Utilize the method according to this invention can make T shape, compound (doppel-), cross-sectional profiles U-shaped or L shaped equally.
The mandrel that adopts in the method according to the invention can be shaped as taper.That it can be configured to be made of a part or constituted by many parts.Mandrel itself also can be crooked, thereby can utilize the method according to this invention to make Crystallizer tube for the circular arc conticaster.
