Abstract
An apparatus for observing the interior of a blast furnace system includes a visible light guiding unit which defines a light path along a viewing axis that is radial to an upright axis of a furnace wall body of a blast furnace and which is adapted to be secured to a furnace blowpipe to permit the light path to be in visual communication with a tuyere, a beam splitter which is disposed in an accommodation space in the tubular mount to split a beam of light propagating along the light path into a horizontal component so that the operator can observe furnace condition through a peeping hole, and a vertical component, and a video camera system which includes an elongate casing connected to the tubular mount, and a video camera disposed in a cooling chamber of the casing to capture a light image from the vertical component of the light beam.
