摘要/Abstract

摘要： 通过采用100t 电弧炉热装铁水+生铁+优质废钢冶炼、LF二次精炼，连铸坯热装(≥550℃), 连铸坯质量自动判定系统，兴澄特钢生产的20G,25MnG,SA-210C,15CrMoC,12Cr1MoVG,SA-213 TI2 等牌号的高压锅炉管坯钢S、P含量≤0.025%,残余Cu≤0.18%,(As+Sn+Sb+Pb+Bi)≤0.028%, 并具有高的洁净度和实物质量水平。

关键词: 管坯, 高压锅炉管用钢, 残余有害元素

Abstract: By using 100 t arc fumace steelmaking with hot metal + pig iron + quality sorap charging, LF secondary refining, concasting billet hot feeding(temperature for heat fumace ≥550 ℃),and automatic determinant system for quali- ty of concasting billet, the S, P content in steel tube blank for high pressure boiler including 20G,25MnG,SA-210C, 15CrMnG,12Cr1MoVG, SA-213 T12 designations produced at Xingcheng Special Steel was ≤0.025%,residual Cu≤ 0. 18%,(As+Sn+Sb+Pb+Bi)≤0.028%,and has higher cleanliness and quality level of products.
