Abstract
Official abstract text for this publication.
The present invention relates to an electric arc furnace, containing a furnace shell, an electrode, a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface, and a first insulation that electrically insulates between the furnace shell and the furnace shell moving mechanism.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric arc furnace, comprising: a furnace shell; an electrode; a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface, the furnace shell moving mechanism comprising: a first part being fixed with respect to the installation surface; a second part being fixed to the furnace shell and being movable with respect to the first part; and the first part being electrically connected to the second part; a first insulation that electrically insulates between the furnace shell and the furnace shell moving mechanism; and a connecting wire that electrically connects between the first part and the second part of the furnace shell moving mechanism; the connecting wire having a length capable of following an entire movable range of the second part. 2. The electric arc furnace according to claim 1 , wherein: the furnace shell and the furnace shell moving mechanism are independently grounded. 3. The electric arc furnace according to claim 1 , further comprising: a furnace roof that covers an opening of the furnace shell; a furnace roof moving mechanism that moves the furnace roof with respect to the furnace shell; and a second insulation that electrically insulates between the furnace roof moving mechanism and the furnace shell. 4. The electric arc furnace according to claim 3 , wherein: the furnace shell and the furnace roof moving mechanism are independently grounded.
