一、引言: 众所周知,存在钢中的氢能够严重地破坏钢的连续性。氢含量愈高这种危险性也愈大,鞍钢的重轨钢最近发现大量的白点就充分地说明了这点。因此控制钢中氢含量日益显得重要。 应当指出,钢液吸收氢之机构至今尚不清楚,所以有效地控制钢中氢含量仍是迫切需要解决的问题。 根据[6]的理论,渣对于保护钢水起着重要作用。为了了解这点首先就须要了解
First, the introduction: It is well known that the presence of hydrogen in steel can seriously damage the continuity of steel. The higher the hydrogen content, the greater the danger. Heavy-gauge steel from Ansteel recently discovered that a large number of white spots fully illustrate this point. It is therefore increasingly important to control the hydrogen content in the steel. It should be pointed out that the mechanism by which liquid steel absorbs hydrogen is still unclear. Therefore, the effective control of the hydrogen content in steel is still an urgent problem to be solved. According to the theory of [6], slag plays an important role in the protection of molten steel. To understand this we first need to understand
