Abstract

본 발명은 용융환원법에 의해 선철을 제조하는 공정에서 분광을 취입하는 방법 및 그 장치에 관한 것으로서, 용융환원법에 의한 선철제조공정에 있어서 버너를 통해 탄소함유 분진 및 분말광석을 동시에 취입하여 탄소함유 분진의 연소열에 의해 용해, 응집된 분말광석에 잉여의 미용융분광을 부하하므로서 용융분광과 미용융분광간의 응집을 발생시키므로서 취입분광의 분진화를 극소화할 수 있는 선철제조공정에서의 고 분말광석 취입방법 및 그 장치를 제공하고자 하는데, 그 목적이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for injecting spectroscopy in a process for producing pig iron by a melt reduction method. In the process of manufacturing pig iron by a melt reduction method, carbon-containing dust and powder ore are simultaneously blown through a burner. Blowing high powder ores in the pig iron manufacturing process, which minimizes the dusting of blown spectroscopy by causing the coagulation between molten and undissolved spectroscopy by loading surplus undissolved spectroscopy to the powder ore dissolved and aggregated by the heat of combustion. It is an object of the present invention to provide a method and an apparatus thereof.

본 발명은 입도가 1mm 이하인 분광과 탄소함유 분진을 취입하는 내관(21)과 산소함유가스를 취입하는 외관(22)으로 이루어진 주버너(2)와 입도가 8mm 이하의 분광을 취입하는 1개 이상의 부버너(1)가 한조로 구성되어 있는 선출제조공정에서의 고분광취입장치 및 이 장치를 이용하여 고 분광을 취입하는 방법을 그 요지로 한다.The present invention comprises a main burner (2) consisting of an inner tube (21) for injecting carbon-containing dust and an outer tube (22) for injecting oxygen-containing gas, and one or more particles for injecting a spectrum with a particle size of 8 mm or less. The summary is made into the high spectral blow-in apparatus in the selection manufacturing process in which the sub-burner 1 is comprised by one set, and the method which blows in high spectroscopy using this apparatus.
