Definitions
- the invention relates to a method for generating Hot strip made from wrought magnesium alloys.
- Magnesium is that Metal with the lowest density Strength properties similar to aluminum and could substitute this as a lightweight material.
- a basic problem hot rolling of wrought magnesium alloy sheets consists in that the common starting material Block or continuous casting solidified coarse-grained and porous, also strong segregations and coarse excretions contains.
- the cast blocks often become one Subjected to homogenization annealing and then at Temperatures between approx. Hot rolled at 200 and 450 ° C. These requirements usually require a number of repetitions Intermediate heating of the rolling stock, otherwise failures as a result Cracks develop.
- a disadvantage of the known method is that for the production of the primary material Magnesium powder creates this powder that compresses and that then accelerated cooling must be carried out. The associated apparatus and personnel expenditure leads to high manufacturing costs. It also shows that the forming of the primary material in In the course of hot rolling despite the complex production of Is difficult to master.
- JP 06293944 A a method for producing a Magnesium sheet known, in which initially from a 0.5 -1.5% SEM, 0.1 - 0.6% zircon, 2.0 - 4.0% zinc and as Remaining magnesium-containing melt poured a slab becomes. This slab is then made in two stages hot rolled, being in the second stage of hot rolling the rolling temperatures between 180 - 230 ° C, preferably 180 - 200 ° C and a total deformation of 40-70%, preferably 40-60% is reached. That so tape obtained should have good ductility.
- the two-stage hot rolling does however also the rolling process and the one to be observed Temperature control is complex and difficult to control.
- the invention was based on the object Specify the procedure with which reduced Manufacturing cost magnesium sheets with improved Let formability be created.
- this object is achieved by a method solved to create a magnesium hot strip, in which a melt from a magnesium alloy continuously to a supporting strip with a thickness of is cast at most 50 mm and in which the cast Supporting tape directly from the pouring heat at one Hot rolling start temperature of at least 250 ° C and at most 500 ° C to a hot strip with a final thickness of is hot rolled at most 4 mm, whereby in the first Rolling of hot rolling a reduction in thickness of at least 15% is achieved.
- a supporting strip with a thickness of cast up to 50 mm which due to its low Thickness cools down quickly and as a result an improved, has fine-grained and low-pore structure. Micro and Macro segregations are to a minimum in this state reduced.
- the so achieved particularly fine-grained structure favors formability during the subsequent hot rolling by the softening that is favorable for further forming facilitated.
- the training of one is also supported fine structure through the first hot rolling pass achieved thickness reduction of at least 15%.
- Another advantage of the applied according to the invention continuous casting from pre-strips Magnesium material with subsequent, from the casting heat Rolling takes place is that the previously at Manufacture of magnesium sheets to be accepted Proportion of scrap is significantly reduced.
- a suitable remelting and casting technique results in addition, extensive procurement independence of the starting material.
- the Energy requirement in the applied according to the invention Casting rolling technology minimized and great flexibility with regard to the spectrum of the products produced guaranteed.
- the invention can be particularly economical Carry out the process by directly opening the supporting strip the casting heat is hot rolled out. Depending on the Properties of the processed alloy and the equipment conditions, it can also be favorable Rolling temperature of the preliminary strip in the course of a before Hot rolling performed temperature compensation adjust. Through this temperature compensation a uniform temperature distribution in the opening and a additional structural homogenization achieved.
- Oxidation of the belt surface and the formation of unwanted oxides in the structure can surely be avoided that the casting of the melt in one suitably trained solidification device under Shielding gas is carried out.
- the microstructure can be further favored if the reduction in thickness in the first pass of hot rolling is at least 20%.
- the deformability of the strip during hot rolling ensure the hot rolling start temperature be at least 250 ° C.
- hot magnesium band can be in produce the inventive method even if hot rolling is reversed in several passes.
- Hot rolling Bridge downtime during which one continuous continuation of the rolling process is not is possible, it is favorable if the hot strip at least after the first stitch on a warm reel coiled and at the respective forming temperature is held.
- the forming temperature at which the hot strip is on the reel is preferably included at least 300 ° C.
- the deformation properties and the desired thickness of the finished rolled strip should be the total degree of forming achieved during hot rolling at least 60% be.
- the process according to the invention can preferably be carried out under Use a wrought magnesium alloy that up to 10% aluminum, up to 10% lithium, up to 2% Contains zinc and up to 2% manganese.
- a wrought magnesium alloy that up to 10% aluminum, up to 10% lithium, up to 2% Contains zinc and up to 2% manganese.
- zirconium or Contribute cerium in contents of up to 1% each.
- the casting and rolling system 1 comprises in the conveying direction F arranged one behind the other a melting furnace 2 Solidification device 3, a first driver device 4, scissors 5, a second driver device 6, one Homogenization furnace 7, a first coiler 8, a third driver 9, a reversing roll stand 10, a fourth driver 11, a fourth reel device 12 and a roller table 13.
- the reel device 12 and the roller table 13 are on a platform 14 set up transversely to Conveying direction F can be moved in such a way that in a first operating position the reel device 12 and in a second operating position of the roller table 13 at the end of the conveyor path 15 one generated in the casting and rolling mill 1 Magnesium tape is arranged.
- the homogenization furnace 7 and the coiler 8 arranged on a platform 16, so that one of these facilities in a first operating position next to conveyor 15 and in a second Operating position in the conveyor path of the to be generated Magnesium tape is arranged.
- the reel devices 8 and 12 are not with here heaters shown equipped via the each on the reels, also not shown wound strip at the respective forming temperature can be held until the next rolling pass is carried out.
- a melt is continuously cast under a protective gas atmosphere with the exclusion of oxygen to form a preliminary strip.
- Typical alloys of this melt are given in Table 1 below:
- HP has proven to be particularly advantageous (high purity) - Magnesium alloys proven.
- alloys contain less than 10 ppm Ni, less than 40 ppm Fe and less than 150 ppm Cu.
- solidified supporting tape is scooped using scissors 5 and by the drivers 4 and 6 on the conveyor path 15 through the Homogenization furnace 7 promoted.
- Temperature compensation instead, in the course of which one evenly distributed over the cross-section of the supporting strip Rolling temperature is set, which is in the range from 250 - 500 ° C.
- the supporting strip tempered in this way then reaches the Driver 9 promoted in the reversing stand 10 and undergoes a first hot rolling pass there.
- the the thickness reduction achieved is at least 15%.
- the hot strip leaving the rolling stand is removed from the Coiler device 12 coiled and in the for next forming stitch optimal forming temperature.
- the platform 16 brought into the operating position in which the Reel device 8 is in the conveyor path 15. Subsequently the hot strip is cut to its final thickness in several passes rolled of less than 4 mm, being each alternately through the reel devices 8 and 12 wound up and at the respective forming temperature is held. The latter is above 250 ° C.
