APPARATUS AND A METHOD FOR MEASURING INCLUSIONS OF A HOT SLAB CAPABLE OF IMMEDIATELY PROVIDING PROCESS FEEDBACK BY IMMEDIATELY MEASURING PRODUCT QUALITY ONLINE

摘要

PURPOSE: An apparatus and a method for measuring inclusions of a hot slab are provided to measure the nonmetallic oxide-based inclusions and precipitates existing inside the hot slab online.;CONSTITUTION: An apparatus for measuring inclusions of a hot slab comprises an optical system (110), a spectrophotometry part (120), and an operation part (130). The optical system irradiates beams to a slab (1) and receives plasma optical signals generated from the slab by the beams. The spectrophotometry part separates and measures a special spectrum generated from the inclusions of the hot slab according to the plasma optical signals receiving from the optical system. The operation part measures the wavelength intensity of the special spectrum measured by the spectrophotometry part.;COPYRIGHT KIPO 2013;[Reference numerals] (121) First spectrum measuring unit; (122) Second spectrum measuring unit; (130) Calculation processing unit
