摘要

以流体力学有关理论为基础

应用FLUENT软件建立高炉鼓风系统的模型。根据高炉操作工艺的需要

通过改变高炉某几个风口的直径

堵塞某几个风口

模拟研究这种操作对各风口间风量分配的影响;模拟研究风口回旋区的形状

并确定风量、风压、焦炭粒度和风口直径等对风口回旋区形状的影响。结果表明

堵塞风口将导致各风口间风量分配的不均匀性加大;风口直径减小时

该风口处的风量将显著减少;风口回旋区深度随风量、风温、风口直径以及风口插入深度增加而增加

随风口前焦炭粒度的增加而减少。

Abstract

Based on the theories of fluid mechanics

a model of blast furnace supply system was established using the FLUENT software.According to the needs of blast furnace operation process

influences of different operation ways on the tuyere blast distribution were analyzed by changing diameter of the tuyere and plugging some tuyeres.The shape of the raceway was visualized to determine effects of the blast volume

blast pressure

coke size and tuyere diameters.The results reveal that when the tuyere was plugged

the blast volume distribution could exhibit more inhomogeneous

while diameter of the tuyere was reduced from 130 mm to 120 mm

the blast volume can be decreased significantly.In addition

tuyere raceway depth was increased with increasing in the blast volume

blast temperature

tuyere diameter and tuyere insertion depth

while it was decreased with the increase of coke size.
