连轧用板坯(以下简称板坯)在加热炉内加热而产生的氧化铁皮已有十几年没有做过测量,一般都以理论烧损率2%来进行计算。实际上,板坯在加热炉内的烧损与钢种、板坯规格、燃料种类、加热时间等有很大关系。为了准确地确定板坯在加 Rolling with the slab (hereinafter referred to as slab) in the heating furnace and the resulting oxide scale has not done a dozen years of measurement, the general theoretical burn rate of 2% to calculate. In fact, slab burning in the furnace and steel, slab specifications, fuel types, heating time has a great relationship. In order to accurately determine the slab plus
