Abstract
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.
Description
Technical field
The present invention relates to a kind of large specification mould steel steel ingot, belong to field of metallurgy.
background technology
The remelting of tradition twin-stage is all generally the little ingot shape of 600 kilograms to 3.5 tons, in order to produce large specification mould steel roundwood more than φ 400mm diameter, requires steel ingot diameter must reach more than 1 meter, and existing steel ingot does not meet processing request.
Summary of the invention
For above-mentioned existing problems, the invention provides a kind of large specification mould steel steel ingot, by the improvement to steel ingot the ratio of width to height and tapering, can meet large specification mould steel roundwood Production requirement, be convenient to again de-ingot simultaneously.
In order to reach above object, the present invention takes following technical scheme, a kind of large specification mould steel steel ingot, entirety coning, is characterized in that: the cross section of described steel ingot is for circular, and longitudinal section is trapezoidal, long 980 ㎜ of trapezoidal upper base, the length of going to the bottom is 1040 ㎜, is highly 1300 ㎜, and the tapering 1 of steel ingot is spent.
Because the present invention has taked above technical scheme, by the ratio of width to height of ingot shape, tapering improves, and this steel ingot weight can reach 8 tons, has met large specification mould steel roundwood Production requirement, and de-ingot is convenient simultaneously.
Accompanying drawing explanation

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
embodiment mono-
As shown in Figure 1, a kind of large specification mould steel steel ingot, entirety is coning, it is characterized in that: the cross section of described steel ingot is for circular, longitudinal section is trapezoidal, and long 980 ㎜ of trapezoidal upper base, permit error ± 10 ㎜, the length of going to the bottom is 1040 ㎜, permitting error ± 10 ㎜, is highly 1300 ㎜, permits error ± 10 ㎜, the tapering 1 of steel ingot is spent, and permits error ± 0.01 degree.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
