技术简介

本项目采用料场一回转窑一矿热电炉的工艺生产含 钒铁水和富钛渣。回转窑预还原焙烧：回转窑窑头设煤粉燃烧装置，对回转窑进行补热。使得回转窑出口焙砂的金属化率达到约80%，约1000℃C的焙砂在窑尾排出进入焙砂缓冲仓内。

Introduction

In this project, the process of "quarry - rotary kiln - ore-smelting electric furnace" is adopted to producevanadium-containing molten iron and titanium-rich slag, Rotary kiln pre-reduction roasting: The rotary kiln headis equipped with a pulverized coal combustion device to supplement heat for the rotary kiin, Thus, themetallization rate of calcine at the outlet of the rotary kiln reaches about 80%, and the calcine at about 1000℃ isdischarged into the calcine surge bin at the kiln tail.
