住友金属鹿岛广3号连续追火酸洗线采用最新技术生产SUS304，430，409和401级不锈钢。这条生产线最主要的特征是具有直火燃烧式垂直退火炉、炉况模糊逻辑可变控制和气垫式带钢浮动传送系统。退火炉由预热段、加热段和均热段组成。预热段靠燃烧废气对流传热使带钢升温，加热段用
Sumitomo Metal Kashima wide continuous 3 recovery pickling line using the latest technology to produce SUS304, 430, 409 and 401 stainless steel. The most important feature of this line is the vertical flame-fired vertical annealing furnace, fuzzy variable furnace temperature control and air-cushion strip floating conveyor system. Annealing furnace by the preheating section, heating section and the heating section. Preheating section by combustion exhaust convection heat transfer strip heating, heating segment
