Definitions
- Double roller casting machines In addition to “double roller” casting machines are others Casting machines in testing or in development. What these machines have in common is that at least a wall of the casting gap is moved during casting and the tape by continuously pressing Shells of solidified molten metal is produced.
- tape An essential goal in the manufacture of cast In practice, tape is a high quality To produce tape material, its material properties are homogeneous over its length and cross section. On such an even distribution of its properties having band can be used both during the Pour the following rolling steps as well as during forming in the intended component shape well and with Process repeatable success.
- Tailored blanks are concerned are boards that are made by combining having different properties Sheet metal blanks are made. That way you can Tailored blanks, for example, in each of the areas be trained particularly resilient, in which they as Body components during practical use or are subject to special requirements during production, while less stressful in everyone else Areas optimal in terms of their weight have reduced thickness.
- the task is to create a process which is the inexpensive manufacture of metal strip, steel strip in particular, enables one with regard to its later use optimized distribution of its Has material properties.
- the band core contains fewer alloy elements than the rest of the band. After the original and reshaping of the Due to the small thickness, the tape is quick Cooling down from the pouring heat. As a result, the Band core different properties than the outer areas a tape cast according to the invention.
- Process can be low alloyed or use microalloyed steel alloys, which typically 0.01 - 0.80% by weight C, 0.30 - 5.00% by weight Mn, ⁇ 0.50 wt% Cr, ⁇ 0.10 wt% Al, ⁇ 0.80 wt% Si and the balance iron and unavoidable impurities contain.
- the 0.10 - 0.8 wt .-% C and 1.00 - 5.00 wt .-% Mn contains, this alloy preferably in addition to iron and impurities other than chromium preferably in concentrations of up to 0.5% by weight no further alloying elements are added.
- the steel according to the invention can be up to 0.05 % By weight Ti, up to 0.05% Nb, up to 0.01% N, up to 0.02 % By weight S, up to 0.02% by weight P, up to 0.2% by weight Ni, to 0.1% by weight of Mo and up to 0.1% by weight of W.
- the Origin of the respective areas of the cast tape can by the targeted cooling of the cast tape supported after its exit from the casting gap become.
- a two-roll casting machine has proven itself.
- Such Casting machine makes it easy to put on the tape exerted force in the casting gap vary that the speed is varied at which the walls bounding the pouring gap move, which in the case of the two-roll casting machine by the Circumferential surfaces of the rollers delimiting the casting gap be formed.
- the diameter of the rolls is preferably 200 mm to 2000 mm.
- the forces in the casting gap can also be Change in those taking place over the walls in question Cooling of the melt solidifying on them affected become. So a larger cooling causes a stronger one Increasing the thickness of the solidified shells and thus higher forces in the casting gap, while by a low Cooling on the walls of the casting gap the thickness of the solidified shells and consequently the casting forces can be reduced.
- the achieved Cooling speeds should be at least until Reaching certain limit temperatures of at least 30 K / s be.
- This can cool the cast strip in at least two successive stages with different cooling rates, where the cooling rate is from the casting heat outgoing temperature range up to 800 ° C should be at least 30 K / s while in the of Temperature range from 800 ° C to 300 ° C preferably at least 10 K / s but at most 500 K / s is.
- the cooling can be done with splash water as well also done with gases.
- One with regard to the diversity of the Products that can be produced according to the method of the invention is a particularly advantageous embodiment of the invention characterized in that adjacent portions of the cast tape with different Cooling rates are cooled.
- the different cooling in the different areas of the cast tape in cooperation with the inhomogeneous distribution of the alloy elements that a different transformation in the areas is achieved.
- you can cast Create tapes where not only the core area and the adjacent outdoor areas a have different characteristics, but it zones can also be used in the external areas create their properties for example as a result a specifically reduced cooling the properties of the Core area adapted or as a result of a special strong cooling are clearly different from the Properties of the adjacent area.
- the differently cooled sections can in the longitudinal or transverse direction of the cast tape extend. It is also conceivable to only use certain closely delimited sections of the cast tape to cool so that the properties desired there locally narrowly trained, while the remaining band is cooled less, so that this less refrigerated areas other properties mint.
- the two-roll casting machine 1 has two axially parallel arranged to each other, a casting gap 2 along its Longitudinal bounding casters 3.4 on a Not shown, adjustable cooling device from the inside be cooled with cooling water.
- the roles 3.4 consist preferably made of a copper alloy and can with a Nickel coating.
- the center distance of the casting rolls 3.4 is fixed set that the depth of the casting gap 2 of predetermined thickness D of the cast strip to be produced B corresponds. Are via a controller, not shown the speeds of the opposite direction in the conveying direction F of Band B in the casting gap 2 conveying casting rolls 3.4 adjustable.
- the cast strip B is in the vertical conveying direction F conveyed downwards from the casting gap 2.
- Delivery direction F extends behind the casting gap 2 below the casting rolls 3.4 across the width of the belt B a cooling device 5.6.
- Every single one of the nozzles of the Cooling devices 5,6 is also not one Control device shown controllable, so that in nozzles arranged in certain rows or columns apply cooling fluid K, such as water, together as a group, while none of the others at that time Cooling fluid K emerges.
- melt S is in the Pouring gap 2 poured so that it is above the casting gap 2 forms a melt pool 7.
- the melt S solidifies thereby on the rotating casting rolls 3, 4 to shells N1, N2, from the casting rolls 3, 4 into the casting gap 2 be promoted.
- the thickness of the shells N1, N2 at Entry into the casting gap 2 depends on it Dwell time on the casting rolls 3, 4, i.e. the time that passes until they arrive in the casting gap 2.
- the shells N1, N2 meet in the casting gap 2 and are squeezed together between the casting rolls 3, 4.
- G1, G2 forms a core area in the cast strip B.
- C which has properties other than those of it adjacent outer areas A1, A2 of the cast strip B.
- the cast strip B then passes through the Cooling devices 5.6.
- the Cooling devices 5.6 are two in the longitudinal direction L of the tape B extending, distributed over the width of the band B.
- Stripe areas S2, S4 of a particularly intense, through direct application of cooling fluid K brings about cooling subjected, while in the side of each Strip areas S2, S4 or arranged between them
- Strip areas S1, S3, S5 direct cooling omitted. This way, in the outer Areas A1, A2 with the stripe areas S1 - S5 in essentially matching zones of different Material properties trained.
- Cast tape produced shows when leaving the Casting gap 2 in the strip core 0.04 wt .-% carbon and the surface of the outer areas A1, A2 0.08% by weight Carbon on.
- the 0.1 - 0.8 % By weight C 1.0 - 5.0% by weight Mn (in the specific example 1.5 wt .-% Mn) and up to 0.5 wt .-% Cr, so remains in the due to the high cooling rate directly cooled strip areas S2, S4 of the areas A1, A2 near the surface predominantly get austenitic structure, which has a high Has elasticity.
- manganese acts as Austenite former, the carbon remains in the Austenite in solution.
- zones Zh in which the components in question 8,9,10 subjected to high loads in practical use are particularly high strengths
- the other zones Zg in which the manufacture of the Components 8,9,10 a particularly large deformation takes place, are soft and stretchy.
- the components 8,9,10 in a simple manner are manufactured in a material-saving and cost-effective manner can nevertheless be used as carriers for high loads.
