摘　　要：基于风口小套上部熔损的理论基础,从烧毁热流出发,分析了铜的导热性对小套熔损的影响,提出了铜的纯度要求及对P含量的控制;计算了适宜的风口小套冷却水速、入口水压;分析了高炉原燃料对小套熔损的影响,着重提出了铅会加剧小套的熔损;在生产操作方面,提出控制软熔带根部不能太低,以利于减轻小套的烧损。This article analyzes the theoretical basis of the melting loss of the tuyere upper,starting from the burning heat flow,analyzes the influence of copper's thermal conductivity on the melting loss of the tuyere,proposes the purity requirements of copper and the control of P content.Calculate the suitable cooling water speed and inlet water pressure for the tuyere of the inlet.Analyze the impact of blast furnace raw materials on the melting loss of tuyere,with a focus on proposing that Pb will exacerbate the melting loss of tuyere.In terms of production operations,it proposes to control the root of the soft melt strip not to be too low,which is beneficial for reducing the burning loss of the tuyere.
