Energy-efficient Induction Melting & Energy Auditing
固态感应炉节能熔炼与能耗审计配方

中频感应炉熔铜能耗约 500–650 kWh/t，优化要点：石英干打料炉衬烧结致密以减少热损；熔化期满功率、精炼期降至 40% 功率保温；加炉盖减少辐射（敞盖热损失可达 20%）。每周记录吨耗电建立能源基线；炉料入炉前 150–200℃ 烘干，既防爆溅又省电 3–5%。变频电源做功率因数补偿至 0.95 以上，综合可节能 10–15%，单位能耗异常升高 10% 即应检查炉衬与密封。
Induction melting of copper runs 500–650 kWh/t; optimize with a sintered dense quartz dry-lining, full power during melting and 40% holding power for refining, and a lid — open-bath radiation can reach 20% of losses. Log kWh per tonne weekly as an energy baseline. Pre-dry charges at 150–200°C to prevent splash-outs and save 3–5% power. Power-factor compensation on the solid-state supply to 0.95+ yields 10–15% overall savings; investigate linings and seals whenever unit consumption rises 10%.
