一种长度≥500mm的长纤维棉钢用盘条及其生产方法
摘要：
一种长度≥500mm的长纤维棉钢用盘条，其组分及重量百分比含量为：C：0.06～0.10%，Si：0.085～0.24%，Mn：0.85～1.20%，P≤0.020%，S≤0.020%，O[T]≤0.01%，Als≤0.005%；生产步骤：铁水脱硫及转炉冶炼；常规进行钢包吹氩及预脱氧造渣；LF炉精炼；连铸成坯；常规加热并高线轧制；常规延迟冷却并集卷待用。本发明生产出的纤维长度不低于500mm，且更细，盘条抗拉强度不超过420MPa，断面收缩率不低于70%，手感柔和，不掉渣。适用于石材、瓷砖的打磨及各种高档家具的抛光和清洁，且极易降解，由于成分主要是铁，降解之后不会污染环境。
摘要（英）：

The invention discloses a steel wire rod with a length of greater than or equal to 500 mm used for long-fibered steel wools, which comprises the following components in percentage by weight: 0.06-0.10% of C, 0.085-0.24% of Si, 0.85-1.20% of Mn, less than or equal to 0.020% of P, less than or equal to 0.020 % of S, less than or equal to 0.01% of O [T], and less than or equal to 0.005% of Als. The production method comprises the following steps: carrying out molten iron desulphurization and converter melting; conventionally carrying out ladle argon blowing and pre-deoxidation for slag making; carrying out refining in a LF furnace; carrying out continuous casting on the obtained objects so as to obtain blanks; conventionally heating the blanks and carrying out high-speed wire rod rolling; and carrying out conventional delayed cooling on the obtained product and collecting coils for standby. The length of fibers produced by using the method disclosed by the invention is not less than 500 mm, and thinner, the tensile strength of the steel wire rod is not more than 420 MPa, the percentage reduction of area is not less than 70%, and the steel wire rod is soft in handfeel, and no slag drops. The steel wire rod is applicable to the polishing of stone materials and ceramic tiles and the burnishing and cleaning of various high-grade furniture, and extremely easy to degrade; and because the main composition is iron, the steel wire rod after degraded does not pollute the environment.
