鼓风炉的风口弯头装置
摘要：
一种鼓风炉的风口弯头装置（10），包括构造成安装在竖炉壁（12）中的风口本体（20），风口本体（20）包括面向竖炉的内部的前表面（24）和相对的后表面（26），风口通道（28）从后表面（26）延伸至前表面（24）。风口弯头装置（10）还包括连接在风口本体（20）的后表面（26）与热鼓风供应系统（38、39）之间的吹风管（34），吹风管（24）具有连接至风口本体（20）的前部（32）和连接至热鼓风供应系统（38、39）的相对的后部（36）。提供燃料喷枪（40、40’），以用于将燃料供给到竖炉中，并且提供气体喷枪（44、44’），以用于将氧化气体供给至竖炉，燃料喷枪（40、40’）穿过风口本体（20）而布置。根据本发明的一个重要方面，气体喷枪（44、44’）布置在吹风管（34）的后部（36）中，气体喷枪（44、44’）以这样的方式布置：将氧化气体供给到通过吹风管（34）供给的热鼓风流的中部中。
摘要（英）：

Tuyere stock arrangement (10) of a blast furnace comprises a tuyere body (20) configured for installation in a shaft furnace wall (12), the tuyere body (20) comprising a front face (24) facing an interior of the shaft furnace and an opposite rear face (26), a tuyere channel (28) extending from the rear face (26) to the front face (24). The tuyere stock arrangement (10) further comprises a blowpipe (34) connected between the rear face (26) of the tuyere body (20) and a hot blast air supply system (38, 39), the blowpipe (24) having a front portion (32) connecting to the tuyere body (20) and an opposite rear portion (36) connecting to the hot blast air supply system (38, 39). A fuel injection lance (40, 40') is provided for feeding fuel into the shaft furnace and a gas injection lance (44, 44') is provided for feeding an oxidizing gas to the shaft furnace, the fuel injection lance (40, 40') being arranged through the tuyere body (20). According to an important aspect of the invention, the gas injection lance (44, 44') is arranged in the rear portion (36) of the blowpipe (34), the gas injection lance (44, 44') being arranged in such a way as to feed the oxidizing gas into a central portion of a stream of hot blast air fed through the blowpipe (34).
