By analyzing the dynamics condition of ladle top-slag desulphuration and the physical and chemical properties of slag and combining production practice, the compositions of the modifier were confirmed, that is, Al 13%～17%, Al2O3 58%～62%, SiO2 8%～12%, MgO 3%～7% and salts＜8%. In the experiment, different amount of modifiers were used instead of the refining agent in original process (for Q235C steel grade).

为降低钢包顶渣的氧化性，通过分析钢包顶渣脱硫的动力学条件及炉渣的理化性能，结合生产实际，确定了顶渣改质剂的组成：Al 13%～17%，Al2O3 58%～62%，SiO2 8%～12%，MgO 3%～7%，盐类＜8%，改质剂具有高效实用、成本低、环境友好的特点。

In the paper,on the basis of analysizing the effects of preventing the looseness of vertical nuts, the author points out that in reality, vertical nuts can't control precompact forces,nor can enhance the strength of thread joining sets, and therefore can't be suitable for thread joining of key parts.

在对对顶螺母的防松效果进行力学分析的基础上，指出在实际操作中，对顶螺母不能有效地控制预紧力，也不能提高螺纹联接的强度，因此，对顶螺母不宜用于重要部位的螺纹联接。

It use two disparting surface,and its frame is fast.It use point moulding gob,so,it can fall off automatism.When it is pulled out ,the pulling pole pull the product and accomplish the pulling of its side concave .
