Title:
POWER DISTRIBUTION STRUCTURE OF MELTING FURNACE
Document Type and Number:
Japanese Patent JP2015081685
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power distribution structure of a melting furnace that enables elongation of the service life of the power distribution structure and stable operation of the melting furnace.SOLUTION: A power distribution structure for supplying electric power to an electric heater of a melting furnace includes a connecting portion 10 for interconnecting a supply electric wire 2 for supplying a power source from outside and a heater electric wire 3 connected to the electric heater. In the connecting portion 10, a conducting path is formed by bar-shaped or plate-shaped conductor members 11-16 formed of an electrically-conductive material. Since frequency of repair work of the conducting path can be reduced, shutdown of the melting furnace due to the repair work of the conducting path can be reduced, so as to enable stable operation of the melting furnace. Since insulating coating is not applied to the conductor members 11-16, the members are disposed so as not to come into contact with other members of the melting furnace. Thus, electrical leak from the conductor members, etc. can be also prevented.
