<P>PROBLEM TO BE SOLVED: To provide a system for semi-continuous casting of aluminum, using a bottom block which can effectively restrain deformation on a bottom section even though casting a slab having a cross section in which the ratio of (length of a long side/length of a short side) is large. <P>SOLUTION: The system for semi-continuous casting of aluminum includes a water-cooled mold opened at up and down directions, and the bottom block for blocking a lower part of the mold at the time of starting casting, in which a solidified ingot is descended together with the bottom block by pouring molten metal to the top face of the bottom block in the mold in casting. In the system, the bottom block in which the horizontal cross section is a rectangle, and in the periphery of the top face of the bottom block, the long side is formed at a mountain shape having an inclined section gradually increasing its height rather than a corner angle section intersected between the long side section and a short side section and each point of the long side section excluding the corner angle section is higher than each point of the short side section, is applied as a bottom block. <P>COPYRIGHT: (C)2013,JPO&INPIT |
