摘要

针对高炉风口容易损坏的部位

用数值模拟方法来模拟高炉风口的流场和温度场

得到流场与温度场的关系。结果表明

当进口水速为8m/s时

冷却效果最好;进口速度继续提高对冷却效果影响不明显

反而使压力损失急速增加。当冷却水中杂质含量较多时

会形成一层类似绝热层的水垢

水垢对风口温度的影响较大。模拟发现

当水垢的厚度达到0.4mm时

风口的温度超过了纯铜风口的许用温度

风口易损坏。

Abstract

Aiming at easily damaged parts of blast furnace tuyere

flow field and temperature field of blast furnace tuyere were simulated by the Fluent software.The results show that when the inlet water speed is 8m/s

cooling effect exhibits desirable.If the inlet water speed is more than 8m/s

cooling effects is further improved slightly

however

pressure loss is enlarged sharply.When impurity content in the cooling water is much

a similar thermal barrier layer of scale can be formed to affect greatly the temperature of tuyere.Simulated results reveal that when the scale of the thickness is more than 0.4 mm

tuyere temperature is more than the allowable temperature of pure copper tuyere

resulting in the damage of tuyere.
