锻造加热炉节能改造三板斧：炉衬换 160 mm 厚 1260℃ 级陶瓷纤维模块替代重质砖，升温能耗降 20–30%；烟道装换热器把助燃风预热到 250–350℃，燃烧效率提 8–12%；炉门加装密封与自动点火，消灭常明火。燃气炉吨铜锻件能耗可从约 90 m³ 天然气降到 65 m³。实践要点：记录每班气耗与产量建立单位能耗基线，异常升高 10% 即检查炉压与密封；余热还可引入锻件缓冷坑做退火保温。
Three retrofits cut forging-furnace energy: swap heavy brick for 160 mm ceramic-fiber modules (1260°C grade) for 20–30% lower heat-up energy; install a recuperator preheating combustion air to 250–350°C for 8–12% better combustion efficiency; seal doors and add auto-ignition to eliminate standing pilots. Gas use for copper forging falls from about 90 to 65 m³ per tonne. Log gas and output each shift as a unit-energy baseline, inspect furnace pressure and seals on a 10% excursion, and route exhaust heat to slow-cooling pits for annealing stock.
