摘要:
A hot metal car (3) is used for the transport of molten pig iron from a blast furnace to a steel making plant, the car (3) having an opening through which it is filled and emptied. To restrict heat loss from the car (3), the opening is closed by a disposable cover (10) which is at least partly lost into the molten iron during the course of the emptying or filling of the car at the end of the journey from the blast furnace to steel plant and back.
摘要:
A hot top lining slab (2) for an ingot mould (1) used in the casting of e.g. steel ingots has a plurality of ribs (4, 5, 6, 7, 8) on its back face and is thick and of low density matter. The ribs (4, 5, 6, 7, 8) define a plurality of enclosed recesses (9) spaced inwardly from the periphery of the slab. The slabs (2) enable the amount of head metal to be reduced but sound ingots still obtained.
