Title:
APPARATUS AND METHOD FOR MEASURING HEIGHT OF MOLTEN MATERIAL IN BLAST FURNACE
Document Type and Number:
WIPO Patent Application WO/2018/221891
Kind Code:
A1
Abstract:
Provided are an apparatus and a method for measuring the height of a molten material in a blast furnace, the apparatus comprising: a measurement part provided on the surface of the blast furnace and measuring the vertical and horizontal strain rates, of the surface of the blast furnace, caused by the height change of the molten material; and a control part for monitoring the height of the molten material by using the vertical and horizontal strain rates measured by the measurement part, and controlling the operations of the blast furnace on the basis of a result of monitoring, thereby measuring the vertical and horizontal strain rates of the surface of the blast furnace by using a strain sensor having an optical fiber grating sensor applied thereto, and enabling the height of the molten material to be measured on the basis of the strain rate change according to the amount of the molten material.
