3) 铸轧带板缺陷及其消除办法在日常生产中,铸轧带坯经常发生的缺陷主要是热带、裂口、孔洞、粗大晶粒和厚度不均。现将我们掌握的这些缺陷产生的主要原因和消除办法总结如下。 a.热带。这种缺陷是液体金属在铸轧区内的局部地区尚未完全凝固,呈熔融状态被轧辊带出来,没有受轧制变形的金属带。产生原因有三种:①液态金属温度偏
3) cast strip defects and elimination methods In daily production, casting strip often defects are tropical, cracks, holes, coarse grains and uneven thickness. Now we master the main shortcomings of these defects and elimination methods are summarized below. a. tropical. This defect is the liquid metal in the casting area has not yet completely solidified in some areas, the molten state was brought out of the roll, there is no deformation of the metal strip. There are three causes: ① liquid metal temperature bias
