Steel ingot for large size die steel

The invention relates to a steel ingot for large size die steel. The steel ingot is in a conical shape integrally. The steel ingot is characterized in that the cross section of the steel ingot is in a circular shape; the longitudinal section of the steel ingot is in a trapezoid shape, wherein the length of the upper bottom of the trapezoid is 980 mm, the length of the lower bottom of the trapezoid is 1040 mm, and the height of the trapezoid is 1300 mm; the taper of the steel ingot is 1 degree. According to the technical scheme of the steel ingot of the large size die steel, the ratio of width to height and the taper of the ingot shape are improved, the weight of the steel ingot can reach 8 tons, and accordingly the production requirements of large size die round steel are met and meanwhile ingot stripping is convenient.
