An electric spark building-up of metal on the working surfaces of rolls is effected by applying a voltage from an unipolar current source to each roll being treated and to an electrode interacting with the surface of the rolls. Building up of metal is effected continuously in the course of operation, the rate of the metal build-up exceeding the rate of wear of the roll surface until a limit layer of metal is formed the thickness of which is maintained constant, thereby maintaining the initial shape of the roll working profile. The device for electric spark treatment is mounted on the rolling stand so that the electrodes and sliding contacts are in contact with the rolls, the electrodes interacting with the working surfaces of the rolls.

The withdrawal apparatus comprises a housing through which a cast ingot passes, said housing being mounted for reciprocating movement and for travelling in the direction along which the cast ingot is withdrawn and then back to its initial position. Mounted in the housing are shoes and wedge blocks with rollers arranged therebetween, said rollers being locked into position between the shoes and wedge as the housing travels in the direction of withdrawal of said cast section. The shoes are associated with a rod fitted with a compression spring bearing up against the housing and producing a force acting in the direction opposite to the movement of the housing during the withdrawal operation. When the withdrawal cycle is over, the shoes being spring-biased, release or unlock the rollers.
