Title:
EARLY ALARM FOR DAMAGE OF CERAMIC LINING OF MELTING FURNACE CONTAINING MOLTEN METAL
Document Type and Number:
Japanese Patent JP3305359
Kind Code:
B2
Abstract:
PURPOSE: To guarantee high indication reliability by an arrangement wherein a ceramic sheet including a mesh electrode and being lined to a furnace has thermal and electrical conductivities lower than or equal to or higher than those of a ceramic material for lining the furnace and thereby an electrode canbe fixed easily to the outside of the furnace lining.
CONSTITUTION: In an early alarm being connected with an evaluation unit, at least one electrode is provided, as a mesh electrode 7, on one side of a ceramic sheet 9 or 10 arranged on the side provided with the mesh electrode 7 or the opposite side. The sheet 9 or 10 has thermal and electrical conductivities lower than that those of a ceramic material for furnace lining 2 in first case. In second case, thermal and electrical conductivities are set substantially equal to or higher than those of the ceramic material for lining the furnace.
