Claims (10)

Claims 1. A continuous casting method in which the crystallizer gradually moves away from a source of liquid metal to form a continuous ingot having a crust and a liquid core, and the molten metal enters the cavity of the crystallizer 10 89 352 from the crust of the continuous ingot, with a bad crystallizer coat cooled in casting time according to patent no. 71527, characterized in that the crystallizer mantle (80) and the closure wall move with respect to each other. 2. The method according to claim The process of claim 1, wherein the end wall portion is heated at least before the start of the casting operation and during the casting. 3. The method according to p. The method of claim 1, characterized in that during casting the mantle of the crystallizer (80) moves relative to the closing wall in a reciprocating motion. 4. The method according to p. The method of claim 1, characterized in that the end face of the crystallizer extends axially between its mantle as molten metal is poured into the crystallizer. 5. The method according to p. The method of claim 4, characterized in that the seal around the front portion of the movable end wall moves with the closure wall, preventing metal from escaping from the crystallizer between its cloak and closure wall. 6. The method according to p. The method of claim 5, wherein a lubricant is introduced between the seal and the crystallizer shell to form a lubricant film between the inner surface of the crystallizer shell and the ingot. 7. Continuous casting device according to patent no. 71527 comprising an intermediate vessel, a crystallizer with a cooled jacket, one end of which is open and the other end is closed, a sliding end wall, and a trolley on which a crystallizer with a bottom is placed and a side outlet is attached it is at or near the drain opening of the intermediate tank, characterized in that it has a sliding closing wall (190, 102) of the crystallizer (80) situated inside the shell (86, 184) of the crystallizer (80) and a drive mechanism (154, 88). ), (192, 194, 196) of the sliding closure wall (102, 190) relative to the mantle of the crystallizer (80). 8. Device according to claim 6. A heating element as claimed in claim 7, characterized in that interchangeable heating elements (108, 114) are disposed inside the wall (102). 9. Device according to claim 7. The method of claim 7, characterized in that the drive mechanism for moving the closing wall (102, 190) relative to the shell (86, 184) of the crystallizer is provided with control-restraining means to ensure that the wall moves from a rear position away from it. tank while pouring the crystallizer. 10. Device according to claim 7, 8 or 9, characterized in that the drive mechanism for moving the wall (102, 190) relative to the shell (86, 184) of the crystallizer (80) is provided with a gear for inducing a relative reciprocating movement between said shell. and the wall (102, 190) during separation of the crystallizer from the intermediate vessel 89 352 FIG. 2 10 µm 14- and HI, | li "!
