一种抗氢致裂纹容器钢的轻压下控制方法
摘要：
一种抗氢致裂纹容器钢的轻压下控制方法，属于炼钢连铸技术领域。采用连铸坏生产，先以几何心部的固相率作为判定标准，将固相率55％～85％之间位置作为开始压下位置，固相率100％的位置为第一阶段压下结束位置；再把固相率为101％的位置作为开始压下位置，把固相率为110％～150％之间的位置作为第二阶段压下结束位置。优点在于：成本低、容易实现、控制稳定等特点，易于推广。
摘要（英）：

The invention provides a soft pressing control method for container steel resistant to hydrogen induced cracks, and belongs to the technical field of steel-making continuous casting. The soft pressing control method for the container steel resistant to hydrogen induced cracks comprises the steps that a continuous cast billet is produced, and with the solid fraction of the geometrical center of the continuous cast billet as the criterion, the position with the solid fraction being 55%-85% is used as a pressing starting position, and the position with the solid fraction being 100% is used as the pressing ending position in the first stage; and then the position with the solid fraction being 101% is used as the pressing starting position, and the position with the solid fraction being 110%-150% is used as the pressing ending position in the second stage. The soft pressing control method for the container steel resistant to hydrogen induced cracks has the advantages that the soft pressing control method has the characteristics of low cost, easy implementation, stable control and the like, and popularization is easy.
