钢的镇静时间对氢的作用及气孔的影响

The effect of Killing time of the Steel to the Action of Hydrogen and the formation of Blow Holes

运用R H-2定氢仪和电化学氢渗透装置,研究了镇静时间对铸钢件中氢的含量、氢的扩散过程及对气孔形成的影响。

With the help of RH - 2 hydrogen indicator and the electrochemical hydrogen penetrating device, the effect of killing time to the content of hydrogen , the hydrogen dissipation process and the formation of blow holes in steel castings are investigated and studied .
