Cold forging steel and production method thereof

The invention relates to cold forging steel and a production method thereof, and belongs to the field of steel smelting. By strictly controlling the argon blowing process of the cold forging steel in the LF refining process, the argon blowing process is subdivided into five stages, and the argon blowing flow and the argon blowing time of each stage are controlled, so that large particles, small particles and other various sizes of inclusions in the steel can be effectively promoted to float upwards, and the adsorption effect of liquid level steel slag on the inclusions is improved; and through fine control over a plurality of process nodes in other smelting steps, including aluminum slag ball slag washing and aluminum wire quantitative adding in converter smelting, and aluminum slag ball deoxidation, aluminum supplementing and calcium treatment in LF refining, the inclusions in the cold forging steel are further eliminated. 本申请涉及一种冷镦钢及其生产方法，属于钢铁冶炼领域。本申请通过严格控制冷镦钢在LF精炼过程中的吹氩工艺，将吹氩工艺细分为5个阶段，并且控制每个阶段的吹氩流量以及吹氩时间，可
