根据步进梁式燃气加热炉的工作原理,分析了其使用过程中炉衬维修率高、料坯跑偏、料坯黑印、炉压波动大等几个容易出现故障的原因,并对这些关键问题进行研究论证和技术优化,提出了相应的解决办法和改进措施。通过现场实际运行,提高了设备的可靠性,生产能效高,减少了生产维修。 According to the working principle of the walking beam gas heating furnace, the reasons that the furnace lining repair rate is high, the deviation of the material billet, the blackout of the billet and the fluctuation of the furnace pressure are analyzed are analyzed. The problem carries on the research demonstration and the technical optimization, proposed the corresponding solution and the improvement measure. Through the actual operation on the spot, the reliability of the equipment is improved, the production efficiency is high, and the production and maintenance are reduced.
