摘要
为满足对高强韧矿用树脂锚杆钢筋的需求,山东石横特钢集团有限公司通过合理的化学成分及生产工艺设计,成功地开发出σs>600MPa、δ5>18%、AK>25J的优质树脂锚杆钢筋。该钢筋在煤矿巷道中支护效果明显,可比普通强度锚杆钢筋用量减少5%以上。
The high strength and toughness RHRB 600 hot rolled resin anchor steel bark （σ8〉600MPa, δ5〉18 %, AK 〉25J） have been developed in Shandong Shiheng Special Steel Group Co. by reasormble composition and technology design. The material can be saved more over 5 % by this bar instead of common bar.
