连续铸锭是熔炼之后进行的工序,该工序的任务和要求是: (1)铸锭的几何尺寸合格。铸锭的尺寸是根据型材断面尺寸、挤压工艺和挤压筒尺寸等因素确定的,铸锭在凝固和冷却时要发生收缩,通常应根据下式确定结晶器断面尺寸:
Continuous ingot melting process is carried out after the task and the requirements are: (1) ingot geometry qualified. The size of the ingot is determined by factors such as the cross-sectional profile of the profile, the extrusion process and the size of the extrusion cylinder. The ingot shrinks during solidification and cooling. The cross-section of the mold should normally be determined according to the following formula:
