Abstract
The invention discloses a method for preventing a horizontal continuous casting unit copper bush from thermal deformation, and belongs to methods. The technical scheme includes that the method includes the steps of forming a groove one side, close to a furnace body, of water jacket, tightly filling an asbestos cord in the groove, brushing a layer of glass water, fully filling finely-broken furnace manufacturing material between a binding surface of the water jacket and a crystallizer after the water jacket and a graphite plate are mounted, and then compacting. The method for preventing the horizontal continuous casting unit copper bush from thermal deformation has the advantages of avoiding and reducing copper bush surface deformation caused by thermodynamic activity, decreasing copper bush trimming times, effectively guaranteeing close fit between the copper bush and the graphite plate, and the like, and has good popularization and application value.
Description
Technical field
Patent of the present invention relates to a kind of copper sheathing preventing hot deformation method, and especially horizontal casting unit copper sheathing preventing hot deformation method belongs to copper processing casting technology field.
Background technology:
The horizontal continuous-casting method is produced the non-ferrous alloy Strip, with respect to traditional semi-continuous casting method, be characterized in that fund input is few, take up an area little, instant effect, and slab does not need through hot rolling, produce streamline and relatively reduce, used by increasing enterprise just gradually.
Horizontal casting mainly is comprised of copper sheathing, graphite cake and shell with crystallizer.During use, the temperature rise of copper sheathing derives from body of heater and graphite cake conducts heat, and the thermal conductivity of copper sheathing is greater than graphite cake, water jacket Yin Wendu raises and thermal expansion occurs, cause the screw bearing of water jacket and graphite cake to produce the internal stress existence, in the production of serialization, this pressure exists always.Crystallizer uses when removing, the radiating rate of water jacket is greater than graphite cake, water jacket Yin Wendu reduces and volume contraction, because the bearing of water jacket and graphite cake is because of the existence of internal stress, crystallizer one leaves body of heater, cause the temperature difference of water jacket and graphite cake to increase rapidly, the pulling force between water jacket and graphite cake also increases rapidly, and little distortion occurs at water jacket copper face screw place.
The surface smoothness that uses rear dismounting water jacket is measured, found that high point appears in the screw place, produce difference in height all around with water jacket, water jacket need just can reuse through the surface grinding machine grinding, causes water jacket shortening in service life.At present, good solution is not also arranged.
Summary of the invention
The technical assignment of patent of the present invention is the method that a kind of horizontal casting unit copper sheathing preventing hot deformation is provided for above-mentioned deficiency of the prior art, and the method for this horizontal casting unit copper sheathing preventing hot deformation has avoiding and alleviates distortion that the copper sheathing surface produces because of thermodynamic activity, reduces copper sheathing reconditioning number of times, effectively guarantees the characteristics such as fit tightly between copper sheathing and the graphite cake.
Patent of the present invention solves the technical scheme that its technical problem adopts: make groove at water jacket near the one side of body of heater, filled stone cotton cord closely in groove, brush afterwards one deck bath of glass, after water jacket and the graphite cake installation, its binding face and and the crystallizer shell between fill up cupola drop material in small, broken bits, then beat reality.
The method of a kind of horizontal casting unit copper sheathing preventing hot deformation of patent of the present invention is compared with existing technology, and has following outstanding beneficial effect: avoid and alleviate distortion that the copper sheathing surface produces because of thermodynamic activity, reduce copper sheathing reconditioning number of times, effectively guarantee the characteristics such as fit tightly between copper sheathing and the graphite cake.
The specific embodiment
Explain below the method for a kind of horizontal casting unit copper sheathing preventing hot deformation of patent of the present invention done.
The method of a kind of horizontal casting unit copper sheathing preventing hot deformation of patent of the present invention, its technical parameter requires: make groove at water jacket near the one side of body of heater, filled stone cotton cord closely in groove, brush afterwards one deck bath of glass, after water jacket and the graphite cake installation, its binding face and and the crystallizer shell between fill up cupola drop material in small, broken bits, then beat reality.
When crystallizer is installed on the body of heater, form thermal insulation layer between copper sheathing and the body of heater, the temperature rise of copper sheathing depends on that graphite cake conducts the heat to it, water jacket and graphite cake temperature Synchronous lifting, the thermal deformation resistance between them reduces.When crystallizer when body of heater is removed, cupola drop material in small, broken bits around water jacket and the graphite cake, its tendency to heat radiation all around is suppressed, this moment, the current that water jacket is interior were depended in the heat radiation of water jacket and graphite cake, the heat of graphite cake constantly is transmitted to the copper sheathing surface, leave by copper sheathing heat conduction, the drop in temperature of water jacket and graphite cake also reaches unanimity, and the thermal deformation pulling force reduces.
By this kind method, the irregularity degree on water jacket surface needs flat surface grinding by original 0.1mm() be reduced to 0.02mm(and do not need flat surface grinding), water jacket is reused number of times will obviously be increased, and prolong service life.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
