Definitions

the invention relates to a hardenable copper alloy as a material for production of blocks for the side dams of strip caster.
the side dams consist, for example, of the US patent 3 865 176 known belt casting machine made of metal or Side dam blocks with T-slot, which are on a flexible endless belt, e.g. B. from Steel that are lined up and that are synchronized with the casting lines in the longitudinal direction move.
the side dam blocks (dam blocks) delimit those by means of the casting belts a mold cavity formed.
EP 0 974 413 A1 is formed from blocks with tongue and groove Side dam chains for belt casting machines are known.
the advantage of this further developed Form blocks with tongue and groove lies in a more precise alignment and guidance of the blocks in the casting process and leads to an improvement in the surface quality of the cast strand.
the heat of solidification dissipating from the molten metal is also a high thermal Conductivity of the mold block material required.
optimal fatigue behavior is of crucial importance of the material that ensures that after leaving the casting line the thermal stresses that occur when the blocks are recooled for tearing the blocks in the corners of the built in for holding the steel band T-slot leads.
Particularly high thermal stresses are necessary due to the less favorable geometry and mass distribution - with side dam blocks in the tongue and groove design is to be expected.
a side dam block made of the CuNiSiZr alloy described in EP 0 346 645 B1 tends to be disadvantageous at very high mechanical and thermal Stresses in the casting operation of a strip caster at an early stage Wear on the side edges and pouring surfaces. This wear is like test results have shown - on a material softening of the cast edges and areas attributable to a value below 160 HV. Furthermore, the Thermal shock resistance of the well-known CuNiSiZr alloy when used as Side dam block with tongue and groove not always out to prevent cracking in the T-groove effective in the casting insert.
the invention is based on the object age-hardenable copper alloy as material for the production of side dam blocks of strip casting systems, especially those in tongue and groove design, for To provide, which even at high casting speeds changing temperature stresses is insensitive and high wear resistance resistance to softening and great resistance against cracking in the T-groove.
Another improvement in the mechanical properties of the side dam blocks, in particular an increase in tensile strength can be advantageous according to claim 2 can be achieved in that the copper alloy 1.8 to 2.4 wt .-% cobalt, 0.45 to 0.65% by weight beryllium, 0.15 to 0.3% by weight zirconium, up to 0.05% by weight Contains magnesium and / or up to 0.1% iron.
the invention allows that according to the features of claim 3 in the Copper alloy up to 80% of the cobalt content can be replaced by nickel.
part of the zirconium content by up to 0.15% by weight of at least one element from the cerium, hafnium, Group comprising niobium, tantalum, vanadium chromium, manganese and titanium his.
the blocks for the side dams are advantageous from double belt casting machines the copper alloy according to the invention according to claim 5 by the process steps Casting, hot forming, cold forming up to 40%, solution annealing at one in the temperature range from 850 to 970 ° C and a 0.5 up to 16-hour curing treatment at 400 to 550 ° C.
the copper alloy according to claim 6 Hot forming can be cold worked by 5 to 30%.
One within this area horizontal degree of cold deformation of 10 to 15% is particularly preferred.
the side dam blocks in the hardened state a tensile strength of at least 650 MPa, in particular 700 to 900 MPa, a Vickers hardness of at least 210 HV, in particular 230 to 280 HV, an electrical conductivity of at least 40% IACS, in particular 45 to 60% IACS a hot tensile strength at 500 ° C of at least 400 MPa, in particular of at least 450 MPa, a minimum hardness of 160 HV 500 hours of aging at 500 ° C and a maximum grain size according to ASTM E. 112 of 0.5 mm.
the invention is explained in more detail below on the basis of exemplary embodiments.
the advantages of the copper alloys according to the invention are shown on three alloys according to the invention (A, B and C) and three comparison alloys (D, E and F).
the composition of the copper alloys in percentages by weight is given in Table 1 below: alloy Co (%) Ni (%) Be (%) Zr (%) Si (%) Cr (%) Cu (%) A 2.1 - 0.54 0.18 - - rest B 2.2 - 0.56 0.24 - - rest C 1.3 1.0 0.48 0.15 - - rest D - 2.0 - 0.16 0.62 00:34 rest e 2.1 - 0.55 - - - rest F 1.0 1.1 0.62 - - - rest
composition of alloy D is a known one CuNiSi base alloy, while E and F standardized CuCo2Be and CuCoNiBe materials are.
All copper alloys were melted in an induction crucible furnace in the continuous casting process to round blocks with a diameter of 280 mm shed.
the round blocks of the sample alloys A, B and C were on one Extrusion press at a temperature above 900 ° C to form flat bars Dimension 79 x 59 mm extruded and then with one Cross-sectional decrease of 12% drawn to the dimension 75 x 55 mm.
the Blocks of the comparative alloys D, E and F became direct at the same temperature extruded to the dimension 75 x 55 mm and no additional Subjected to cold forming.
the CuCoBe and CuCoNiBe materials were then solution annealed at 900 to 950 ° C and in the temperature range cured between 450 and 550 ° C for 0.5 to 16 hours.
the CuNiSi base alloy was solution annealed at 800 to 850 ° C and under the same Conditions hardened.
the tensile strength Rm, the Vickers hardness HV10, the electrical conductivity (as a replacement for the Thermal conductivity), the grain size according to ASTM E112, the heat resistance Rm at 500 ° C and the softening resistance via Vickers hardness measurement (HV10) after aging determined at 500 ° C after a period of 500 hours.
the extent of the cracks found in the T-slot was in those classified as "cracked" Form blocks at 2 to 5 mm, in individual cases the crack length was up to 10 mm.
the comparison shows that compared to the materials E and F only those produced according to the invention with additional low cold forming
copper alloys A, B and C with optimal properties uniform and fine-grained structure and the necessary resistance to Show cracks when used as a form block with tongue and groove.
the copper alloys according to the invention have use as a conventional mold block a significantly better softening resistance than the known CuNiSi alloy D and a slightly better softening resistance compared to alloys E and F.
the copper alloy according to the invention is therefore extremely suitable as a material for the production of all of them changing during the casting process Mold blocks subject to temperature stress for the side dams of Strip casters. These are both the previously used form blocks as well as the Mold blocks in the tongue and groove design according to EP 0 974 413 A1.
