CN110846584A 一种大规格混凝土电杆用钢及其生产方法 有权

一种大规格混凝土电杆用钢及其生产方法
摘要：
本发明提供了一种大规格混凝土电杆用钢及其生产方法，包括以下重量百分比成分C 0.23-0.25％，Si 0.40-0.55％，Mn 1.30-1.45％，V 0.015-0.025％，P≤0.035％，S≤0.035％，其余为Fe和不可避免的杂质。与现有技术相比，本发明是提供一种φ16mm规格电杆盘卷钢DG400的生产方法，增加了电杆钢DG400产品的规格，填补了大规格市场上电杆用钢的空白。且该规格混凝土电杆钢的开发，提高了单位面积的受力强度及抗裂性能，且节约了材料成本。
摘要（英）：

The invention provides steel for large-specification concrete poles and a preparation method thereof. The steel comprises the components in percentage by weight of 0.23-0.25% of C, 0.40-0.55% of Si, 1.30-1.45% of Mn, 0.015-0.025% of V, P not more than 0.035%, S not more than 0.035% and the balance of Fe and inevitable impurities. Compared with the prior art, the invention provides a preparation method of phi 16 mm pole roll steel DG400; the specifications of pole steel DG400 products are added; and the blank of the steel for large-specification market poles is filled up. Through development ofthe steel for the concrete poles with the specifications, the stress strength and the cracking resistance in unit area are improved, and the material cost is saved.
