i 219/126 3 Claims, 1 Drawing Figure ll l l i SHAPED INGOT S The present invention relates to apparatuses for electroslag melting of shaped ingots.
An apparatus for electroslag melting for the production of shaped ingots is known in the art which comprises a split cooled crystallyzer having a longitudinal slot at its side wall, a slide arranged in said wall, a melting vessel rigidly mounted on said slide, said melting vessel communicating with the crystallyzer through this slide, said slide having a level sensor for sensing the metal level in the crystallyzer, a drive for moving the slide and the melting vessel in the vertical direction, and consumable electrodes mounted in electrode holders.
This apparatus is only capable of producing shaped ingots having no links which are normal to the ingots parallel portions. Ingots including two portions connected by a link with each other cannot be produced in conventional crystallyzers. Examples of such ingots used as manufactured articles are cranks of crankshafts where two webs or cheeks are connected by a pin or neck.
It is the primary object of the present invention to provide an apparatus for electroslag melting for the production of shaped ingots which includes'two parallel portions and a link arranged normal thereto such as ingots of the type used for cranks of crankshafts and for H-shaped and U-shaped ingots.
Itis another object of the present invention to eliminate the formation of shrinkage in cranks in the link members of the ingots produced.
These objects are attained in an apparatus for electroslag melting in the production of shaped ingots comprising a split cooled crystallyzer having a longitudinal slot at its side wall, a slide arranged in said wall, a melting vessel rigidly mounted on said slide and communicating with said crystallyzer through said slide, a level sensor for sensing the metal level in said crystallyzer arranged on said slide, a drive for moving said slide and said melting vessel in the vertical direction, and consumable electrodes mounted in electrode holders, wherein according to the invention provision is made for another similar crystallyzer, each of both crystallyzers having a throat in its wall, said throats being arranged coaxial with each other and adapted for forming link members in an ingot and communicating upon joining the cavities of said crystallyzer, with one of the said crystallyzers being movably mounted along the geometrical axis of said throats and turnable around the horizontal axis which is below said geometrical axis of said throats and at right angles thereto.
The apparatus according to the invention will ensure a highly efficient production of the shaped ingots as well as providing for high performance and excellent quality of ingots having a complicated or complex shape such as cranks of marine diesel crankshafts.
'One of the crystallyzers is preferably equipped with joint pins which may be mounted in brackets of the carriage for moving this crystallyzer.
Due to such an arrangement the ingot shrinkageand deterioration can be avoided.
In order to prevent slag leakage through the gap between the crystallyzer throats a packingbush may be used which should be made of material identical to that of the ingot produced and inserted into the crystallyzer throats.
The above-mentioned and other objects and features of the invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawing, wherein the figure shows a longitudinal elevation view of the apparatus for producing cranks of crankshafts taken along th e a xi of the c rank neck in an electroslag melting apparatus.
Now referring to the drawing, the apparatus comportion or link member 4 of the ingot. A slide 5 is mounted in a longitudinal slot 6 in the wall of crystallyzer 1 which is opposite to throat 3 so that it is capable of travelling in the vertical direction when driven by a drive (not shown in the drawing). A melting vessel'7 whose cavity communicates with the cavity of crystallyzer 1 through a channel in slide 5 is mounted on theslide 5. Crystallyzer 2 has a similar construction, but it is rigidly fixed on a support (not shown in the drawing) whereas the crystallyzer 1 is mounted on a carriage 8 which is freely movable along the geometrical axis of throat 3. The brackets of carriage 8 have joint pins 9 of the crystallyzer I mounted turnably around the horizontal geometrical axis which is below the axis of the throat but normal Each slide 5 has a sensor 10 for sensing the metal level in the corresponding crystallyzerl or 2. A consumable electrode 11 is arranged above each melting vessel 7 and a non-consumable electrode 12 is mounted in the bottom of melting vessel 7. Each melting vessel pair and a crystallyzer shares a common slag bath 13. A packing bush 14 made of the material identical to that of the ingot produced is inserted into throats 3 in order ,to prevent the leakage of flux 13 out of throats 3. I
The smelting of shaped ingots in the apparatus described and made in accordance with the invention is carried out in the following manner.
The melting vessels 7 are mounted on crystallyzers 1 and 2 at their extreme lower positions so that sensors 10 for sensing the metal level in crystallyzers 1 and 2 are positioned against the bottom edges of the forming cavities of crystallyzers .1 and 2.The premelted fluxing agent 13 is poured into melting vessels 7, and the working electric current is fed to the consumable electrodes 11 and the non-consumable electrodes 12. The molten metal produced as a result of the melting down of the electrodes 11 flows over from the melting vessel 7 through the channels provided therein and in slide 5 and then into the cavity of the corresponding crystallyzer 1 or 2. As the level of the ingot being smelted in crystallyzers l and 2 rises and which is registered bysensors! 0 the melting vessels 7 are moved up by thedrive of slide 5 and the electrodes 11 are fed into slag bath 13 in accordance with their melt-off rate by the electrode holders travelling along the columns (columns, electrode holders and their I associated drives are 3 not shown in the drawing. for simplification pur poses; the arrows indicate the direction of travel of melting vessels 7 and the consumable electrodes 11 during the melting process).
When crank neck 4 is being smelted, slag baths 13 of the joined crystallyzers 1 and 2 are united via the cavities of throats 3. A packing bush 14 is inserted into throats 3 to prevent the leakage of the fluxing agent 13 through the gap between these throats. When the ingot shrinks in throats 3 of crystallyzers 1 and 2, crystallyzer 1 is drawn to crystallyzer 2 by the shrinkage forces. Besides, crystallyzer 1 is turned around the horizontal axis of the joint pins 9 by these shrinkage forces, Due to such arrangement for the crystallyzers the formation of cracks in a crank neck 4 is eliminated.
It will be evident that the apparatus described above is shown to be simple and easy to operate andmaintaifdueto the constant distance between the electrodes and to the constant current between the consumable and non-consumable electrodes regardless 1.
