Abstract

The height of the bath mirror (8) is determined using calculated connection of the linear dimensions. The liner dimensions are measured in part directly, indirectly and preferably outside of the high temperature range of the electric arc oven (1). In the process of determining the height of the bath mirror of an electric arc oven (1), the electric arc oven (1) has an oven tank (2) with a slag door (13) and a height adjustable electrode support are (5) for at least a graphite electrode (4).
