Title:
FLOATING MELTING FURNACE
Document Type and Number:
Japanese Patent JP3805410
Kind Code:
B2
Abstract:
PURPOSE: To improve the cooling of a tapping hole, to increase the power applied to an induction coil, to increase the capacity and to be able to melt at a high speed by forming a cooling water passage by passing to the bore side at the tapping hole.
CONSTITUTION: The part corresponding to the tapping hole 5 of a segment 11 is converged toward the inside of the hole 5, a groove 1 is dug from the outer peripheral side to the bore side, a converged end trapezoidal plug 7 is put in the groove 10, and the end of the plug 7 s disposed at the bore side from the passage of a tapping tube 6. Thus, a cooling water passage 41 bypasses to the bore side of the hole 5 to shorten the thermal conduction distance between the passage 41 ad the bore part of the hole 5. The end of the plug 7 is disposed at the bore side from the passage of the tube 6 to eliminate the stagnation of water in the by pass. Thus, the cooling of the hole 5 is improved to increase the power applied to induction coils 2, 3, the capacity can be increased, and high speed melting can be conducted.
