现货锐力REXPOWER减压阀MGV-02-P-1 MGV-03-P-0 MGV-03-A-2
连铸坯生产具体包括以下步骤:
[0034]步骤SlOl:铁水预处理
[0035]将铁水进行脱硫预处理。因为P、S是有害的,且在钢水凝固时是易偏析元素,所以P、S的含量控制应较低。 [0036]铁水预处理工艺:采用镁基脱硫,要求脱硫后铁水中S的质量百分含量< 0.005%,铁水温度> 1270°C。
[0037]步骤S102:铁水冶炼

[0038]铁水冶炼时添加的废钢为钢质纯净的优质废钢。采用顶底复吹转炉脱碳、脱磷。入炉铁水的Si的质量百分含量控制在0.80%以下,过程枪位控制在1.6~2.5m之间,终渣碱度控制在2.6~2.8之间,终点C的质量百分含量控制在0.05%以上,P的质量百分含量控制在0.012%以下。出钢时采用挡渣锥进行挡渣,出钢过程中严禁下渣。
[0039]步骤S103:LF炉精炼
[0040]采取大渣量进行造渣,白渣保持时间控制在Smin以上,使用铝线、铝铁线脱氧;精炼结束后确保软吹时间> 12min ;根据实际情况控制上钢温度,确保钢水过热度控制在17~30°C之间。
[0041]步骤S104:RH炉真空脱气处理
