重庆特殊钢厂与重庆电炉厂共同研制的、用于冷轧带钢半成品和成品氮基气氛保护的光亮热处理新型罩式热处理炉,成功地取代了老式炉子加连续酸洗的工艺。产品质量、热处理成本和环保等方面取得了显著效益。几年实践证明,这种热处理炉具有高效节能、炉温均匀(为±5℃)、密闭性好等优点。与原采用的车底式炉及老式罩式炉相比,热处理时间缩短一半,吨钢热处理成本下降20～50％,作业环境清洁,劳动强度低。产品质量均匀稳定,表面保持冷轧金属光泽,不产生脱 Chongqing Special Steel Works and Chongqing Electric Furnace Factory jointly developed a new type of shroud heat treatment furnace for the bright heat treatment of cold rolled strip semi-finished products and finished products nitrogen-based atmosphere protection, successfully replacing the old furnace plus continuous pickling process. Product quality, heat treatment costs and environmental protection has made significant benefits. Years of practice has proved that this heat treatment furnace with energy efficient, uniform temperature (for ± 5 ℃), airtight and so on. Compared with the original car bottom furnace and the old hood furnace, the heat treatment time is shortened by half and the heat treatment cost per ton of steel is reduced by 20% to 50%. The working environment is clean and the labor intensity is low. Product quality and stability, the surface to maintain the cold-rolled metallic luster, does not produce off
