Abstract

The present invention relates to a melting material height measuring device and method of a melting furnace. The melting material height measuring device of the melting furnace includes: a measuring part arranged on the surface of the melting furnace for measuring the vertical deformation of the melting furnace surface based on the height change of the melting material The rate of deformation and the rate of deformation in the horizontal direction; and the control part, which monitors the height of the melt by using the rate of deformation in the vertical direction and the rate of deformation in the horizontal direction measured in the above-mentioned measurement part, controls the operation of the furnace based on the monitoring results, and can use the applicable optical fiber The strain sensor of the grating sensor measures the deformation rate in the vertical and horizontal directions of the furnace surface, and measures the height of the melt based on the change in the deformation rate based on the amount of the melt.

Description

Technical field [0001] The present invention relates to a melt height measuring apparatus and method of a furnace, and more detail, involving a melt height measuring device and method for determining a furnace of a melt-melted melt-melted melt using a strain sensor suitable for fiber grating sensors. Background technique [0002] The furnace is a furnace for the process of obtaining a metal of the metal ore to acquire a metal of the molten state, and is constituted by a vertical furnace formed by stacked refractory bricks. [0003] Typically, in the furnace, iron ore and coke as raw materials are loaded from the upper portion, and from the lower air outlet, a high temperature hot air and 5g / nm of 5 g / nm. 3 50g / nm 3 The moisture is placed in a well coal having a micro-powder as a helper fuel, and the fuel loaded from the upper portion is oxygen generated from the carbon dioxide generated from the lower air-fed air to the iron ore loading as a raw material. Oxygen Combined to...
