1 坯条中间开花向四周翻卷产生原因:中间走泥快,四周慢,挤出泥条时中心凸出.处理方法:a.中间芯头换新的,以加大芯头的断面;b中部芯杆加粗或加套管,以加大中间阻力;c.改变扁担铁形状,将其改成“Ω”形;d.出口后身的四角做成弧形,以增加四角进泥量;e.芯头排列设计比例不当,四壁太薄,必须重新调整;f.改进压缩机头,在压缩机头的内壁添加分泥板,迫使泥料向
1 The reason why the middle bloom of the billet rolls around is that the middle part is muddy and slow, and the center protrudes when the mud is squeezed out. Processing method: a. The middle core is replaced with a new one to increase the cross section of the core; b. Mandrel bold or casing, in order to increase the intermediate resistance; c. change the shape of the flat iron, it is changed to “Ω” shape; d. The four corners of the outlet back body made of an arc, to increase the amount of mud into the four corners; e. The proportion of the core array design is improper, the four walls are too thin and must be readjusted; f. The compressor head is improved, and the mud wall is added to the inner wall of the compressor head to force the mud towards
