Overhaul and Installation of Incoming Blast Furnace Equipments

通过对以进风弯管建立起来的空间直角坐标系X、Y、Z值分析,找出了引起直吹管不等长,垂直短管加楔形垫的原因。阐明了保证进风设备安装质量的关键是使s_i、y_i值等于设计值,z_i′等于零。介绍了快速测定喇叭管法兰中心的简便方法和几种保证质量的安装措施。

Through the analysis of X,Y,Z in space rectangular coordinates system in base of incoming blast gooseneck pipe,the cause of non—equal length of straight blast pipe and addition of wedge pad for vertical short pipe is found out. The key point for good installation quality of incoming blast equipment is proper values of si,yi,zi'. A simple method of quick measuring the center of tapered pipe flange and some installation measures for increasing quality are also introduced.
