example 1
[0034] Utilize the method according to the present invention to prepare high-strength anchor bolts, which include C0.38%, Si0.27%, Mn0.61%, Cr0.88%, and the balance of iron and unavoidable impurities by weight percentage. The high-strength anchor bolts continuously complete feeding, roller conveying, front traction roller, quenching induction heating, quenching cooling, tempering induction heating, tempering cooling, rear traction roller, roller conveying, unloading, etc. on the induction heat treatment production line. Packaging and other production processes. Quenching heating temperature: 820°C, then cooling, tempering heating temperature: 450°C. The yield strength of the steel bar is 1030MPa, the tensile strength is 1165MPa, the elongation A after fracture is 16.0%, the shear strength is 827MPa, and the impact energy at 20°C is 89J.
