摘要
通过研究调整铸坯火焰清理深度,验证超低碳冷轧搪瓷钢的抗鳞爆性、密着性以及氢渗透性的变化情况。研究结果表明,铸坯火焰清理深度从4mm降低至2mm,超低碳冷轧搪瓷钢没有出现鳞爆现象,密着等级无变化。氢渗透试验结果显示,降低铸坯火焰清理深度至2mm后,氢渗透时间和抗鳞爆敏感性TH值无明显变化,且TH值均>10min/mm^(2),抗鳞爆性能优良。
This paper verifies the changes in scale explosion resistance,adhesion,and hydrogen permeability of ultra-low carbon cold rolled enamel steel by studying and adjusting the flame scarfing depth of the casting billet.The research results indicate that when the flame scarfing depth of the casting billet has been reduced from 4mm to 2mm,and there is no scale explosion phenomenon in the ultra-low carbon cold rolled enamel steel,and there is no change in the adhesion level.The results of hydrogen permeation test showed that after reducing the flame scarfing depth of the casting billet to 2 mm,there was no significant change in hydrogen permeation time and the TH value of anti scale explosion sensitivity,and TH values were>10min/mm^(2),indicating excellent anti-scale explosion performance.
