方坯连铸机结晶器（内腔）形状尺寸，是影响铸坯质量和漏钢率的重要因素之一。介绍一种新型便携式“结晶器点检仪”，它能准确地在线（结晶器安装在连铸机上）或离线测量新或旧结晶器内腔尺寸沿高度和宽度方向的变化情况，为结晶器预知性更换和维修提供了可靠地依据。
Billet caster mold (lumen) shape and size, is the impact of slab quality and the rate of one of the important factors. A new portable “crystallograph” is introduced, which can measure the variation of the cavity size of new or old mold along the height and width accurately on-line (the mold is installed on the continuous caster) or off-line, Predictive replacement and repair provides a reliable basis.
