  • Patent number: 8568652
    Abstract: A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations.

  • Patent number: 8052920
    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.

  • Patent number: 7879133
    Abstract: A method has steps of providing a three-dimensional (3-D) laser scanner, providing a computer, obtaining point group data (PGD) and calculating measuring an outline of a top reactant stratum from the PGD. The step of providing a 3-D laser scanner directs a 3-D laser scanner at reactant strata in a blast furnace and output PGD that represent digital data of an inside of the blast furnace. The step of providing a computer connects the 3-D laser scanner to a computer having a point group analysis program. The step of calculating an outline of the top reactant stratum from the PGD is performed by the point group analysis program to calculate an outline of the top reactant stratum in the blast furnace from the PGD. At least one two-dimensional laser scanner is used to measure a path of the reactant being charged.
