Description
Technical field
The present invention relates to a kind of large-scale great current mixed mode cathode roll.
Background technology
With the immediate prior art one of the present invention be " manufacture method of titanium cathode roller cylinder " patent of invention, publication number CN1570218A earlier makes the titanium coiled sheet welding of cylinder and butt seam place; Butt welded seam and heat affected zone heating, to planish behind the jumping-up of commissure, repeated multiple times, the commissure repeatedly is out of shape, and deflection should by cast structure is out of shape, changes over base material cast structure and organize essentially identical equiaxed structure more than 30% each time, thereby eliminated seam organization and be imprinted on periodicity bright band on the foil, satisfied the manufacturing requirements of foil.This method adopts in two plates welding back and realizes the weld seam jumping-up with external force, because the intensity height of the strength ratio worked structure of welding cast structure, so under the identical situation of 750～950 ℃ of Heating temperatures, upset force, the weld seam as-cast condition is than the difficult distortion of the machining state of sheet material, and it is big to form the mother metal deflection, and cast structure's deflection is little, later stage forges and easily forms folding phenomenon, the loss of mother metal is increased, cause the cylindrical shell size to be difficult to control, be difficult to guarantee the quality of cylindrical shell.In addition, realize that with external force the weld seam jumping-up implements also comparatively difficulty.
It with the immediate prior art two of the present invention " a kind of big specification seamless Ti tube manufacture method and the seamless Ti tube mixed mode cathode roll of making of this material " (CN1196983A) patent of invention, compound of copper-steel that its roller is wrapped up in steel by the steel cylinder of outer field seamless Ti tube and internal layer or copper-clad that copper-weldering of steel explosive clad plate volume forms is composited, main shaft is the copper-steel composite shaft of copper material parcel steel axle, spindle outer wall is welded with flange, conducting plates the inner is fixed by bolts on the flange, the inner welded of roller is in the outer end of conducting plates, electric current is led flange by the main shaft copper sheathing, lead cylinder inboard wall by conducting plates again, lead titanium tube surface at last.This kind structure cannot say for sure to demonstrate,prove big electric current, because wrapping up in the slender axles of steel, copper-clad cannot say for sure to demonstrate,prove the applying rate, conducting plates and flange bolting, the bad meeting of binding face is installed causes partial points contact or cathode roller to rotate use for a long time, bolt looseness, directly influence conduction homogeneity, result can cause the electric current that passes through in the good place of connection contact big, cause the roll surface local superheating, influence the normal use of cathode roller and the quality of foil; On the other hand, internal layer is that the copper-clad of copper-steel explosive clad plate volume weldering formation is wrapped up in the compound tube of copper-steel of steel, in order to guarantee the hot charging dimensional requirement, the outside surface copper layer of the compound tube of copper-steel must add by machine, cause copper layer uneven distribution, influence the homogeneity of titanium tube surface current, finally influence the foil quality.
Summary of the invention
Purpose of the present invention overcomes shortcoming of the prior art exactly, a kind of large-scale great current mixed mode cathode roll is provided, the compound tube of being wrapped up in copper by the ladle that steel-copper explosive clad plate volume is welded into of outer field titanium tube and internal layer is made by the hot charging shrink-fit, fixedly connected with main shaft by two ends conductive casters and copper conducting plates, electric current conducts electricity to roller surface through the copper conducting plates by the conductive casters at main shaft two ends, simple in structure, assembling easily, in, composite surface combination rate height between the skin, conduction good uniformity when importing big electric current, guaranteed that the roller surface electric current is big and be evenly distributed that the foil thickness of producing is even, the quality height.By cast structure is out of shape, cast structure is changed over mother metal organize essentially identical equiaxed structure, be imprinted on periodicity bright band on the foil thereby eliminated seam organization, satisfied the manufacturing requirements of foil.The manufacture method of cylindrical shell need not large-scale specific equipment, and the forging of simple possible, particularly later stage is difficult for forming folding phenomenon, has guaranteed the cylindrical shell size, and the titanium tube cost of production is low, the quality height.Cathode roller
