Being the method of appraising the cement blowing effect inside the methodological and measures the furnace wall remaining thickness of the blast furnace methodological

摘要

PROBLEM TO BE SOLVED: To evaluate a spraying effect of a cement in a blast furnace and to measure the remained furnace wall thickness in the blast furnace.;SOLUTION: A method for evaluating the spraying effect of the cement in the blast furnace is performed as the followings: (a) a step for measuring and obtaining the first time of three-dimensional point group to the outer shape of the inner wall in the blast furnace; (b) a step for performing the cement spraying work to the inner wall in the blast furnace; (c) a step for measuring and obtaining the second time of three-dimensional point group to the outer shape after the cement spraying work on the inner wall in the blast furnace; and (d) a step for obtaining the thickness of the cement spraying by comparing the step (a) of the first time of three dimensional point group and the step (c) of the second time of three dimensional point group, are contained. In this way, it can be inspected whether a constitution of uniform thickness in the cement spraying quality is obtained or not.;COPYRIGHT: (C)2008,JPO&INPIT
