Electro-slag re-melting temperature measuring device and electro-slag re-melting temperature measurement method

摘要

PROBLEM TO BE SOLVED: To provide a temperature measurement device for electro-slag-remelting that can precisely and safely measure temperature of a molten slag pool and a molten metal pool in electro-slag-remelting and a temperature measurement method for electro-slag-remelting.;SOLUTION: The temperature measurement device for electro-slag-remelting that measures temperature of a molten portion in electro-slag-remelting by which an ingot is obtained by melting while distributing power to an electro-slag-remelting electrode, comprises: an optical fiber 10 that receives and transmits radiation light of the melting portion (a molten slag pool 4 and a molten metal pool 5); a radiation thermometer 11 that is connected to the optical fiber 10 and receives the radiation light transmitted by the optical fiber 10 and detects temperature of the molten potion; and a guide member (a guide tube 12)that is fixed to the electro-slag-remelting electrode 1 and positions the optical fiber 10 continuously in an axial direction of the electro-slag-remelting electrode 1 to guide the electrode.;COPYRIGHT: (C)2014,JPO&INPIT
