棒材线加热炉设备模块化改造实践OA

To address the problems of low charging efficiency of the heating furnace in the bar rolling line,uneven load on the support wheels caused by long-term service deformation of the fur-nace bottom frame,frequent shaft breakage,and difficulty in replacing the buffer stop impact heads,a systematic modular modification was implemented.Through the automation upgrade of the charging table,proximity switches and infrared rangefinders were integrated to realize automatic stepping charging.A modular reinforcement scheme was adopted,with four additional sets of fur-nace bottom support moving wheels added,reducing the load per wheel from 4.625×10⁶ N to 3.08×10 ⁶ N,and decreasing the equipment failure rate by 72%.The connection structure of the buffer stop impact head was optimized by replacing the traditional bolted connection with a double-dovetail assembly,significantly improving the disassembly and assembly efficiency.After the modifi-cation,the heating furnace charging achieved full-process automation,eliminating major equip-ment hazards at the furnace bottom,ensuring continuous and stable operation of the production line,and providing replicable practical experience for the upgrade of similar old heating furnaces.
