Embodiment Construction
[0016] Starting from market demand, economic benefits and social benefits, the present invention designs a reasonable chemical composition through the effects of various elements in the material, and produces steel grades with a strength of up to 110psi and impact toughness through smelting and continuous casting, piercing and rolling, and quenching and tempering processes. Far higher than API 5CT standard requirements, and good corrosion resistance, high strength, high toughness and CO2 resistance 2 Corrosion casing. The high-strength, high-toughness anti-CO 2 The specific steps of the preparation method of the corrosion casing are as follows:
[0017] Step S1: Steelmaking production
[0018] Steelmaking production includes: hot metal pretreatment, converter smelting, LF refining, VD vacuum degassing and round billet continuous casting. Nitrogen fixation technology, deoxidation technology, and clean steel technology are used in the steelmaking production process to make bi...
