天津市大成五金厂在两条热镀锌生产线上,对两台低碳钢丝退火炉进行了节能改造,取得显著效果。经天津钢研所等几个单位测定,热效率达到67.2%,取得节约能源(天然气)50%的效果。目前退火工艺单耗稳定在30米~3/吨,其中一号作业线产量提高了15%。该厂采取的综合性节能措施包括:自动控制炉温、炉膛压力、余气系数,采用铸铁片式
Dacheng Hardware Factory in Tianjin in two hot-dip galvanizing production line, the two low-carbon steel wire annealing furnace for energy-saving transformation, and achieved remarkable results. By Tianjin Steel Research Institute and several other units measured, the thermal efficiency of 67.2%, achieved energy conservation (natural gas) 50% of the results. At present, the unit consumption of the annealing process is stable at 30m ~ 3 / t, of which the production line of No. 1 operating line has been increased by 15%. The plant to take a comprehensive energy-saving measures include: automatic control of furnace temperature, hearth pressure, residual gas coefficient, the use of cast iron
