A shoe for dispensing a molten metal such as lead into a mold cavity of a rotating dmm to continuously cast a web of a plurality of serially connected grids or battery composite electrodes of a carbon fiber material with a cast metal conductor. The shoe may have at least one elongate orifice slot in a face confronting the drum, a molten metal supply passage communicating with the Norifice slot and an excess molten metal return slot opening into the confronting face downstream of the supply slot relative generally to the direction of rotation of the dmm.

A control method and apparatus for inhibiting slag entrapment in ladle (1) during continuous casting production. An optimal control model calculating unit (11) receives related signals and data sent by a ladle weight detector (4), a molten steel flow field detector (5), a slag detector (7), a sliding gate opening detector (9), and a process signal interface unit (10), performs calculation and analysis according to an optimal control model to obtain a corresponding optimal control strategy, and outputs the strategy to an electromagnetic brake (6) and a sliding gate controller (8) for slag entrapment inhibition control. Regarding the two processes where a vortex may be formed, by means of different optimal control strategies, which respectively inhibit or destroy the formation of a vortex, slag generation is postponed, and molten steel may flow out without bringing slag out, thereby reducing residual ladle steel and improving molten steel yield.

An unfired, refractory molded body (1), includes a binding agent matrix (2) containing at least one set, permanent binding material and aggregate grains (3) with and/or of biogenic silicic acid, preferably with and/or of rice husk ash, which grains are incorporated into the binding agent matrix (2), for thermal isolation of a molten metal, especially of molten steel, and/or of a metal ingot solidifying from the molten metal, and also the use of the molded body (1) for thermal isolation of a refractory lining, in particular in a multiple-layer brick wall or in a heat-treatment furnace, or as a corrosion barrier, e.g. against alkali attack, or as a fire protection lining or as filter material for hot gases.

A plate, a plate-holding apparatus, and a holding method for the plate for facilitating work to attach the plate to a plate-receiving metal frame of a sliding nozzle device. A gap is ensured between a to-be-held portion of the plate and an inner wall surface of an engagement groove such that, when the plate is held by engaging the to-be-held portion of the plate with the engagement groove of a holding portion of the plate-holding apparatus, the plate is movable in the longitudinal direction, the width direction, and the thickness direction of the plate.
