当钢水注入钢锭模，凝固进程是从模壁和钢锭模底部开始，向中心热区或轴线发展。钢液在凝固时和凝固后体积减小。钢水在凝固过程和凝固结束后伴随着体积收缩，初生坯壳处未得到凝固钢水充分填充，导致铸锭内部出现空洞或在凝固末期出现缩孔。这不同于沸腾钢因气泡而导致的空洞。
此缺陷的严重程度和分布取决于几个因素,包括钢的质量，浇铸时钢水的过热度，浇铸的方式（直接或非直接浇铸），钢锭模的尺寸和锥度。这些空洞也与杂质有关，由于富集、偏析在最终产品中形成了不良元素的不良分布。
因此，减少空洞的数量，并使其发生在对铸锭质量影响最小的位置是非常重要的。
为了实现这些，维苏威拥有一系列的产品和服务，用于减少不良偏析，提高合格铸锭的产量。
这些产品和服务包括：
防缩孔
KALTOP* 板型防缩孔元件
FERRUX* 粉状防缩孔元件
浇铸保护渣
STELOTOL* 粉末或颗粒模铸保护渣
冒口系统
KALMINEX* 发热衬/毡
KALMIN* 冒口绝热板
LITEFAX* 高效冒口绝热板
PROFAX* 绝热衬/毡或板
