摘　　要：针对目前精密铸造行业的能耗问题、环保问题以及工艺稳定性问题,通过采用硅碳棒加热和纤维棉保温的方式对电阻炉进行了改造。结果表明,硅碳棒冷炉焙烧型壳一炉只需140kW·h,比电阻炉冷炉加热节电65%,热炉焙烧只需35kW·h,比电阻炉加热节电53.3%,节能效果显著。Based on the problem of energy consumption, environmental protection and process stability in precision casting industry, the resistance furnace was modified with Si-C rod heating and cotton fibre in- sulation. The results reveal that Si-C rod heating furnace only need 140 kW · h for baking per-furnace shell mold, saving energy 65%, and it only needs 35 kW · h for baking shell mold in the heating fur- nace, saving 53.3 %, compared with those electric furnace ,exhibiting significant saving-energy efficien- cy.
