安装250 t顶底复吹转炉过程中,为了解决狭窄厂房空间内的运输以及高位、高精度安装的技术难题,设计了托圈和炉壳地面分段组装方案,钢包车搭建临时抬架安装下悬挂装置方案,激光三维跟踪仪精确定位下悬挂支座安装方案,钢包车水平移动实现跨梁下转炉水平就位方案,液压千斤顶同步升降实现轴承座垂直精确定位安装方案,有效解决了所面临的安装技术问题,为高精度要求的大吨位转炉设备的安装,提供了宝贵的经验。
During the installation of 250 t top and bottom blowing converter, in order to solve the technical problems of transportation within the narrow plant space and the high-precision and high-precision installation, a sub-assembly scheme of the supporting ring and the furnace floor was designed. Suspension scheme, the laser three-dimensional tracker pinpoint the installation plan of the suspension support, the horizontal movement of the ladle truck to realize the horizontal position of the converter under the beam, hydraulic jacks synchronous lifting to achieve vertical positioning accuracy of the bearing seat installation program to effectively solve the problems faced Installation of technical problems for the high-precision requirements of large tonnage converter equipment installation, provides valuable experience.
