前言在毛主席革命路线的指引下,我国钢铁工业正在飞速发展。为了跟上时代的要求,老厂的技术改造的步伐应该加快,特别是我厂对老而陈旧的一烧车间改造工作已经迫在眉睫。我们在厂党委的正确领导下,对一烧车间当前生产技术方面的薄弱环节——风机使用寿命问题进行了调查研究。在近三个月的工作中,我们对老烧各烧结机抽风系统工作现状、风机磨损的诸原因、风机的改造作了一些初步工作。从而使我们了解了一些问题,弄清了一些现象,为改造抽风系统奠定了一点基础。相 Foreword Under the guidance of Chairman Mao’s revolutionary line, the steel industry in our country is developing rapidly. In order to keep pace with the requirements of the times, the pace of technical renovation of the old factory should be accelerated. In particular, it is imminent that our factory will renovate the old and old one-burning workshop. Under the correct leadership of the party committee of the factory, we conducted a survey on the current production technology of a burning workshop, namely, the service life of the fan. In the past three months of work, we have done some preliminary work on the working status of the exhaust system of the old burning sinter, the causes of fan wear, and the renovation of the fan. So that we understand some of the problems, to clarify some of the phenomena, for the transformation of ventilation system has laid a little foundation. phase
