前言宝钢1号高炉在第一阶段是单炉生产。考虑到高炉是一个连续性生产很强的设备,和上、下工序的连接关系十分密切。如高炉因故休风停产,不仅影响到本身,而且牵连到转炉出钢、焦炉出焦……。从经济效益来考虑,确保高炉安全生产,是从事高炉生产者一个值得经常研究的课题。这里从高炉受电系统的继电保护来说明对重点设备的关键部位进行校核是十分必要 Preface Baosteel No. 1 blast furnace in the first stage is a single furnace production. Taking into account the blast furnace is a continuous production of strong equipment, and the connection process is very close. Such as blast furnace for some reason, stop production, not only affect itself, but also involved in the converter tapping, coke oven out of focus ... .... Considering economic benefits and ensuring the safe production of the blast furnace, it is a topic worth frequently studying in blast furnace producers. Here from the blast furnace power system relay protection to verify the key parts of key equipment is necessary to check
