摘要
介绍利用EBT+VOD+LF+VD四联工艺生产DT4的试验,按照EBT初炼脱磷、脱碳、升温-VOD精炼真空脱碳-LF炉精炼脱硫-VD精炼脱气、去夹杂-铸造等工艺路线,实现冶炼碳≤0.008%、硫≤0.004%、磷≤0.003%、硅≤0.022%和氮≤60×10^(-6)、氧≤30×10^(-6)、氢≤1×10^(-6)的高纯净度的DT4并且无夹渣、气孔、裂纹等铸造缺陷,应用于医疗粒子加速器的电磁纯铁钢。
This paper in the process of development with DT4 electromagnetism pure iron and steel productionprocess operation key technology and the practice experience is introduced using EBT ＋ LF ＋ VD ＋ VOD quadrupleprocess DT4 experiment, according to the EBT dephosphorization and decarburization, at the beginning of heatingvacuum decarburization VOD re？ ning - LF rening furnace desulfurization - VD rening degassing, to mix - casting,such as technology, implementation of smelting 0.008% or less of carbon, sulfur 0.004% or less nitrogen, phosphorus,silicon acuities were 0.022% and 0.003% or less of 60 PPM or less, oxygen 30 PPM or less, high purity hydrogen1 PPM or less DT4 and no casting defects such as slag inclusion, porosity, crack, applied to medical acceleratorelectromagnetism pure iron and steel.
