Abstract

The present invention is a device for calculating the surface level of a molten metal accommodated in a container provided with an outlet, the device comprising: a measuring unit installed in the container so as to measure, at different heights, an induced electromotive force generated by the movement of the molten metal; and a processing unit for determining the surface level of the molten metalby using values measured at the different heights. The present invention can accurately measure the surface level of a molten metal.

Description

technical field [0001] The present disclosure relates to apparatus and methods for measuring surface height, and more particularly to apparatus and methods for accurately measuring the surface height of molten metal. Background technique [0002] Generally, the blast furnace operation includes a process of loading iron ore and coke into the upper part of the blast furnace, a process of blowing hot air into tuyeres defined in the blast furnace to burn the coke, using the heat and gas generated by burning the coke to transfer the iron ore The process of removing impurities and oxygen to produce molten iron. The molten iron in a liquid state is stored in the lower part of the blast furnace, and the molten iron is discharged through the taphole after a period of time. [0003] In this regard, when molten iron is stored at a height equal to or higher than a certain height in the lower portion of the blast furnace because the discharge operation is not performed correctly, hot ai...
