The utility model is characterized in that the crystallizer is composed of a metal steel plate set by welding and partitioned combination; the water slit of the crystallizer can be changed along with the changes of the thickness of a variable camber wall, and can be enlarged along with the wall thickness from 10 mm to 90 mm; the device is provided with at least non-polluted slag pools which are attached to the outside of the shaped consumable electrode, and is provided with an insulating block which has enough of intensity. The utility model has the advantages that the casting defects existing in common sand mold casting can be avoided, and the procedure of duplicating milling can be saved; the utilization rate of materials can reach more than 85%, and the performance can reach the level of forging roll bars of the same material. The utility model also has the advantages of good internal quality, accurate shape lines, small processing amount and short producing periodicity.
Description
Technical field is under the utility model: the making apparatus of turbine blade slab.
Before the present invention, generally adopt sand casting for the manufacturing of hydraulic turbine critical component blade in the world, but this kind method is difficult to avoid the internal soundness defective, directly influences the life-span of the hydraulic turbine.At present, developed country adopts steel plate technology of compression molding again after imitative type mills more, and the blade that this kind method is produced has advantages such as molded lines is accurate, and internal soundness is good, but processing capacity is big, stock utilization is low, and the production cycle is long, the cost height, development along with the water power cause, the hydraulic turbine is to the development of maximization high efficiency, and more and more higher for the requirement of crucial flow passage components blade, existing electroslag molten casting device comprises that crystallizer and consutrode do not possess the condition of founding thin-walled plane of bending blade slab.
The purpose of this utility model is to adopt electroslag smelting casting to make mold pressing thin-walled plane of bending blade slab, can produce flakiness ratio is the blade slab that 16:1 even above curvature constantly change, its device itself has the thermally-stabilised intensity of reliable shape line, to guarantee the precision of product.
Content of the present utility model is:
At first adopt the electroslag smelting casting crystallizer, make the thin-walled plane of bending blade slab can moulding in crystallizer, crystallizer adopts steel plate assembly welding and piecemeal combining structure, metal mold, its design feature is that the water seam of this crystallizer is wide from 10mm to 90mm along with the variation of the plane of bending wall thickness size of slab, the selection of this scope is based on uses water-cooling structure---and the thermal deformation that prevents crystallizer in the fusion-casting process that is controlled to be of water seam has this principle of reliable shape line heat endurance to design to guarantee crystallizer, the utility model crystallizer is by the wide variety of water seam, make that each section of slab has crystallization rate unanimous on the whole in the founding, guarantee Forming Quality at crystallization forward position cast(ing) surface.
Secondly, guarantee under the prerequisite of consutrode and crystallizer safety clearance in the fusion-casting process, guarantee the uniformity of each section packing ratio, make packing ratio reach 0.35-0.75, outside electrode, adhere at least eight for this reason and neither pollute the collets that slag bath has sufficient intensity again, to guarantee the security of fusion-casting process.
The utility model compared with prior art, it had both avoided the casting flaw of ordinary sand casting, and saved the operation that imitative type mills again, its stock utilization can reach more than 85%, the water seam that the utility model device changes with changes of section because of employing, thus intensity of cooling controlled, and it is good to have internal soundness, the shape line is accurate, and its performance can reach with material forging rolling material level; Adopt metal mold, advantage such as it is accurate to have a molded lines, and processing capacity is little, and is with short production cycle; Adopt collets to guarantee the security of fusion-casting process.
The utility model crystallizer is as shown in Figure 1: 1 crystallizer, 2 delivery ports, 3 water inlets, 4 cooling waters, 5 conformal consutrodes, 6 power supplys, 7 slag baths, 8 molten baths, 9 foundry goods, 10 end water tanks.
Figure 2 shows that founding vane plate billet crystallizer sectional drawing: 1 dull and stereotyped crystallizer, 2 consutrodes, 3 sealing crystallizers, 4 curved surface crystallizers, 5 insulation clinkers.
Embodiment of the present utility model:
Key state project natural bridge power station turbine runner blade slab single-piece weight is 1.2 tons, its material is the ZGOCr16Ni5Mo martensitic stain less steel, adopted this equipment to produce, as shown in Figure 1, on crystallizer cooling water gap, be controlled in the 5-70mm scope, 20 collets identical with the slag charge composition are being adhered in the position on the electrode as shown in Figure 2, carry out electroslag smelting casting and obtain shape line slab accurately.
Claims (1)
1, a kind of thin-walled plane of bending blade slab electroslag molten casting device, crystallizer and consutrode are arranged, it is characterized in that: the crystallizer of employing is that metal mold steel plate assembly welding and piecemeal combine, the water seam of crystallizer can strengthen with wall thickness and not wait from 10mm to 90mm along with the variation of plane of bending wall thickness size changes; This device adheres at least eight and does not pollute slag bath outside the conformal consutrode, have the collets of sufficient intensity again.
