Abstract
1,130,659. Measuring thickness of furnace walls. DEMAG ELEKTROMETALLURGIE G.m.b.H. 9 Nov., 1966 [20 Nov., 1965], No. 50269/66. Heading G4H. Apparatus for recording the thickness of the wall of a metallurgical furnace 1 (Fig. 1) comprises a plurality of electrically conducting loops 3 embedded in the wall of the furnace in staggered relation to one another so that when the furnace wall wears away by a determined amount the loop projecting furthest into the wall melts and gives an indication to a remote detector, a switch then being effective to connect the detector to the longest remaining loop. When the loop 3 closest to the furnace lining is fused, the voltage drop across a resistance 6 is removed and a relay 7 de-energized to operate contacts 7a, 7b to step a stepping relay 5 so that by the current flow through the next loop 3 the voltage drop across the resistance 6 is restored. Operation of the contact 7b produces a current impulse to step a relay 8, individual contacts of which are connected to the voltage tap of a voltage divider 9 so that a voltage representing the thickness of the lining wall is fed to a voltage recorder 10.
