Method, system and apparatus for controllably heating copper alloy dam blocks in revolving edge dam chains in twinbelt continuous casters by induction heating of thermally-sprayed ferromagnetic layers bonded in shallow depressions in such blocks. High thermal conductivity of such blocks advantageously quickly conducts inductive heat from ferromagnetic layers into the blocks. For casting a slab of electrolytic anodes having aligned opposed protruding lugs, such chains include uniformly spaced lug-molding pocket blocks. Periodic induction heating of ferromagnetic layers on dam blocks of one chain or the other keeps pocket blocks aligned as revolving chains travel downstream along opposite sides of moving mold casting regions. Directly induction heating copper alloy dam blocks is very impractical. Therefore, ferromagnetic layers are thermally sprayed into depressions in blocks prior to assembling such chains.

For closing gaps between blocks of a moving edge dam prior to its travelling downstream into the entrance of a moving mold defined between upper and lower revolving casting belts moving downstream from the mold entrance to its exit, the moving edge dam is initially elevated into a crest, as shown in FIGS. 12 and 14. This crest is above a plane generally defined by the lower casting belt travelling downstream. Then, a guide roller positioned above thrusts downwardly upon the moving edge dam bending it convex downwardly as shown at "B" in FIG. 14 for causing its dam blocks to press against each other for sliding them along their high strength endless flexibile carrying member, thereby closing gaps between the blocks entering the mold entrance for sealing the entrance against outward leakage of molten metal between blocks. The downward convex bending also produces desired downward pressure of the moving edge dam against the lower casting belt, thereby enhacing sealing action between moving edge dam and lower belt. The downward thrust of this roller is sensed for indicating the amount of tension in the endless flexible carrying member of the moving edge dam.

A method and system are provided for synchronizing the travelling edge dams in the continuous casting of metal slab, strip, or bar, thereby providing a means for the continuous uniform casting of longitudinally spaced edge shapes, contours, or profiles such as integral shoulders, lugs, lobes, depressions, curves, or indentations in the opposite edges of the cast product. Shapes include the protruding lugs, cast directly opposite each other, for suspending copper anodes in electrolytic refining-also the intruding, material-saving contours in the tops of anodes. A belt-type continuous casting machine is shown wherein two moving contoured edge dam loops each comprise blocks strung upon flexible endless metal straps. The moving edge dams on each side of the mold must be synchronized, regardless of disturbing thermal variations notably. "Back breakers" exert upward rolling contact force controllably and separately against each moving edge dam loop along its return path, thereby changing the local curvature and so adjusting the degree of mutual compression and closeness of the constituent dam blocks or the end-to-end spacing of the same.

Electrostatic application of a dusting of dry, electrostatically adherable, thermally insulative powder particles over a workface of a continuous metal-casting machine in which the mold surface or surfaces which provide the workface or workfaces revolve in a generally oval course. A dry dusting of protective powdery refractory material is applied to the workface after being entrained in an air stream and electrostatically charged by suitable electrostatic apparatus. The workface to be dusted is electrically grounded for attracting the charged powder particles for adhering them to the workface. The resultant coating formed by the dusting so deposited is remarkably uniform over a substantial area of the workface, a phenomenon explainable by mutual electrostatic repulsion of the dry powder particles being deposited. Continuously re-applied dusting over the workface during a continuous cast provides an immediately useful repair or replacement of dusting powder lost from the coating on the workface of a revolving mold surface during casting. The dusting may be removed at will by means of an air knife.

An arrangement is provided for feeding a liquid alloyed metal under protective atmosphere into a high speed continuous casting machine for casting a strip of alloyed metal, preferably calcium lead which is subsequently formed into battery grids and the like. The arrangement includes a melting pot and specifically a resilient skid ramp in the melting pot which permits metal hogs to be charged into the melting pot in a nondestructive manner while supporting the hog at a fixed level in the melting pot bath to insure homogeneous mixing of the alloyed elements in the hog during melting thereof.
