摘要
钢中的残余有害元素致使钢材产生红脆性表面裂纹和具有回火脆性倾向 ,并使耐热钢的热强性降低。因废钢中残余有害元素含量较高 ,为降低油井用钢的残余元素含量 ,应在电弧炉炉料中加入一定比例的生铁 (铁水 )
The residual deleterious elements in steel lead to products occurring red brittleness surface crack and temper brittleness, and lead to hot strength of heat resistant steel decreasing. Due to higher content of residual deleterious elements in scrap, the arc furnace charging should contain iron/hot metal or DRI in definite proportion to decrease the content of residual deleterious elements in steel for oil well.
