Abstract
PURPOSE: To make the exact detection of the damaged state of the working surface in a blast furnace possible by making an observing device to be suspended from the top of a blast furnace, having a reduced stcok line, heat resistant and movable vertically and swivelable.
CONSTITUTION: To observe the wall surface of in a furnace 2 with an observing device 5, the stock line is reduced until the wall surface 3a exposes and the operation is stopped and blown down. Next, a vessel 6 containing a television camera 10 connected to a television monitor 8 by means of a cable passed through the inside of a cooling pipe 23, as well as a light projector 13a and a reflection mirror 14, and applied with cooling is mounted to the leading end part of a freely extensible rigid long rod 7. The vessel 6 is inserted into the furnace through the clearance of a furnace body shell 1, and is lowered down to a prescribed position by operating an elevating winch and a winch for elevation of the pipe 23. The projector 13a is lighted by a controller 17, and the swiveling device 9 for the rod 7 and the elevating winch are operated and the wall surface images are projected on the monitor 8 through the mirror 14, whereby the wall surface is observed.
