Abstract
A method for combining the copper plates of the crystallizer used in slab conticastor features that for its wide surface the Ag Cu alloy with high electric and thermal conductivities and lower stretch strength is used and for its narrow surface the GZrGu alloy with high hardness, strength and high-temp deformation resistance is used. Its advantages are long service life and low cost.
Description
Technical field
The invention belongs to slab caster and use the crystallizer field, particularly a kind of slab caster knot product device copper coin mother metal compound formulation.
Background technology
It is to select fine copper for use that the continuous caster crystallizer copperplate mother metal begins, and mainly considers the thermal conductivity height of copper, can rapidly the molten steel heat be distributed.It is low that but its shortcoming is an intensity, yielding under the molten steel casting condition about 1400 degree.Manyly after the eighties replace fine copper with yellow gold, intensity obtains certain raising, but still undesirable, and especially narrow copper plate deformation is big, water steel stove number always the 800-1000 stove pace up and down.The appearance of chrome zirconium copper alloy then has better performance than yellow gold again.Cooperate attrition resistant coating, can the company of making water the stove number and bring up to 2000 stoves.But chrome zirconium copper alloy costs an arm and a leg, and because its base material hardness height, internal stress is also high, and its wide copper coin easily produces thermal crack at the meniscus place of casting molten steel.Planing depth when having strengthened copper coin and repairing, thus the whole service life of copper coin shortened.
Summary of the invention:
The purpose of this invention is to provide a kind of slab caster and select the copper alloy of unlike material with wide of crystallizer and narrow copper plate for use, to give full play to different-alloy in advantage separately that different sites was possessed, overcome its shortcoming, and under the prerequisite that keeps identical work-ing life, significantly reduce the cost of copper plate of crystallizer mother metal.
With copper plate of crystallizer mother metal compound formulation, it is characterized in that wide copper coin of crystallizer select yellow gold for use according to slab caster of the present invention, the crystallizer narrow copper plate is selected chrome zirconium copper alloy for use.
According to compound formulation of the present invention, wide face selects for use yellow gold big to adapt to wide copper coin heat conduction amount, and hardness is moderate under the high temperature, and the strong requirement of ability is split in heat resistanceheat resistant.Leptoprosopy is selected chrome zirconium copper alloy for use, and is poorer slightly than wide copper coin to adapt to the narrow copper plate conductivity, but hardness requires height, the requirement that the high temperature deformation resistance ability is strong.
According to slab caster of the present invention copper plate of crystallizer mother metal compound formulation, the chemical component weight per-cent of described wide copper coin mother metal yellow gold is: silver 0.07～0.25%, copper 98～99%, all the other are impurity, the chemical component weight per-cent of described narrow copper plate mother metal chrome zirconium copper alloy is: chromium 0.08～0.30%, zirconium 0.5～1.5%, copper 97～99%, all the other are impurity.
Adopt this copper coin mother metal compound formulation of the present invention, the high temperature deformation resistance ability that had existed when both having solved leptoprosopy with Kufil causes the problem that angle seam is overproof easily, has solved wide the meniscus place hot tearing serious problems that exist during with chrome zirconium copper alloy again.Evidence, according to slab caster mould work-ing life of compound formulation of the present invention with all adopt chrome zirconium copper alloys identical as the crystallizer life-span of mother metal, but can significantly reduce the cost of crystallizer.Because the price of Kufil only is 55% of a chrome zirconium copper alloy, therefore every crystallizer can reduce cost more than 25%.Because the copper coin decrepitation reduces, access times increase by 20%, the effect highly significant.
Embodiment
According to slab caster of the present invention copper plate of crystallizer mother metal compound formulation, the chemical component weight per-cent of described wide copper coin mother metal yellow gold is: silver 0.08～0.15%, copper 98-98.5%, all the other are impurity, the chemical component weight per-cent of described narrow copper plate mother metal chrome zirconium copper alloy is: chromium 0.12～0.2%, zirconium 0.5～1.2%, copper 97～99%, all the other are impurity.
