The invention discloses a modular construction method for a furnace bottom plate of an MPR furnace in the technical field of smelting reduction equipment construction. The modular construction method for a furnace bottom plate of an MPR furnace comprises the following steps that positioning and paying off are conducted, specifically, measurement and paying off are conducted on a foundation plane according to a construction drawing; sizing blocks are installed, and the foundation plane is leveled through the sizing blocks; a furnace bottom plate and a furnace bottom beam are welded, specifically, the furnace bottom plate is turned over, and lifting lugs are welded to the front face of the furnace bottom plate; the furnace bottom plate is hoisted, specifically, the furnace bottom plate is hoisted to a mounting position by a crane, and the furnace bottom beam and a block slurry method plate are fixed by spot welding. According to the modular construction method for the furnace bottom plate of the MPR furnace, the technical problems that a traditional furnace bottom plate process of the same type of blast furnace is complex in operation, low in installation efficiency, large in site construction difficulty, time-consuming and labor-consuming and the quality is difficult to effectively guarantee are solved, operation is easy, the construction efficiency is high, the quality is guaranteed, and the modular construction method is suitable for site construction.

    本发明公开了熔融还原设备施工技术领域的一种MPR炉炉底板模块化施工方法,该MPR炉炉底板模块化施工方法包括如下步骤:定位放线,按照施工图纸对基础平面测量放线;垫铁安装,通过垫铁对基础平面找平;炉底板和炉底梁的焊接,炉底板翻转,将炉底板翻转在炉底板正面焊接吊耳;炉底板吊装,吊车吊起炉底板至安装位置,将炉底梁与座浆板进行点焊固定。该MPR炉炉底板模块化施工方法解决了传统的同类型高炉炉底板工艺操作复杂,安装效率低,现场施工难度大,费时费力并且质量难以有效保证的技术难题,操作简单,施工效率高,质量有保证,适用于现场施工。
