Abstract
The utility model relates to an extra-thick slab casting process and a continuous casting machine. An extra-thick slab is produced through a vertical casting machine employing a continuous casting method, the problem that a casting blank is too thick to be bent and straightened is solved, the production flow is shortened, the production efficiency is improved, and the production cost is reduced. Meanwhile, due to the adoption of the vertical casting machine, bending and straightening deformation is absent, nonmetallic impurities in liquid steel float upwards easily, and the cleanness of the casting blank is improved. A continuous temperature measuring device and a tundish heating device are arranged in a tundish; the degree of superheat of the liquid steel in the tundish can be stably controlled at the temperature of between 10 and 30 DEG C; and undercooling or overheating pouring is avoided under the condition of low drawing speed. A solidification tail end of the casting blank and a dummy bar are subjected to a soft reduction process, and the problems of center segregation and center porosity in the casting blank are solved. Due to the adoption of modes of vertical cutting and inclined ejection, the casting blank and the dummy bar are reliably output and fed.
Description
Technical field
The utility model relates to the above extra-thick plate blank conticaster in extra-thick plate blank continuous casting technology field, particularly thickness 400mm.
