FEED APPARATUS FOR MOLTEN METAL FOR AN INSTALLATION FOR THE CONTINUOUS VERTICAL CASTING OF A METAL PIPE,IN PARTICULAR FROM CAST-IRON |
摘要 |
In the continuous ascending vertical casting of an iron tube T without the use of a core to form the hollow tube interior, the molten iron is contained in a crucible made up of a cooled tubular die 6, 7 and the base 1 of a syphon unit. The crucible comprises a coaxial central form 5 at least as high as the die, which creates with the latter an annular space for molten iron F. Such arrangement reduces the volume of molten iron in the crucible and thus results in considerable energy savings. |
