Processing method of high-precision H-shaped steel

The invention relates to the technical field of H-shaped steel production and processing, and in particular relates to a processing method of high-precision H-shaped steel. According to the technical scheme adopted in the invention, the method comprises the following steps that: (1) steel raw materials are preliminarily processed through a converter; (2) the raw materials processed through the converter are conveyed to a refining furnace to be subjected to refining processing treatment; (3) the raw materials subjected to refining processing treatment are produced into continuous casting billets through a continuous casting machine; (4) the raw materials of the produced continuous casting billets are weighed; (5) the weighed continuous casting billets are subjected to uniform heating treatment through a heating furnace; and (6) the continuous casting billets are descaled through high-pressure water. The invention has the advantages that: higher surface quality precision is guaranteed; more stable performance o
