DEVICE FOR MEASURING THE TEMPERATURE OF HOT STRIP COIL AND DEVICE FOR MEASURING THE SPEED OF COOLING USING IT

摘要

The present invention relates to a cooling rate measuring device using it, and the temperature measuring device of the wire coil, and more specifically, the number of the temperature of the high temperature heat treated wire coil in the steel mill to within the pre-existing heating by detecting a state of change of the magnetic field to be measured in a non-contact and a temperature measurement device, to a cooling rate measuring apparatus using the temperature measuring device.; A temperature measuring device of the wire coil of the present invention includes a roughing mill (2), mapping the rolling mill after the continuous rolling from 4 can ignore equipment 6 in for measuring the temperature of the wire coil 10 to be cooled by the cooling water in the apparatus, the temperature measuring device is: the wire coil 10 a magnetic field is a coil (20) that is installed to pass through the inside; Core 60 is provided at the upper and lower portions of the coil 20; Converting the magnetic field detecting ammeter 30 for detecting a state of change of current through the coil 20; A voltmeter for detecting the voltage applied to the coil 20 (40); Positive pressure source (50) for applying an alternating current to the coil 20; Shield case for blocking the coil 20 and the core 60 and the outer 80; Calculator for using the current value output from the current meter 30 to the converted temperature value (110); And a temperature indicator 120 for displaying the temperature value received from the computing unit (110).
