Abstract
The utility model discloses a poly-rowed steel ingot mould which comprises a cylindrical mould body with an inner cavity. The shape of the cross section of the inner cavity comprises sunken arc lines uniformly arranged along the circumference and arris formed by two adjacent arc lines, and the shape of the cross section of the outer wall of the mould body is correspondingly consistent with shape of the cross section of the inner cavity. With the adoption of the poly-rowed steel ingot mould provided by the utility model, the inside structure and the surface quality of a steel ingot can be ensured.
Description
Technical field
The utility model relates to many ribs ingot mould field, relates in particular to the many ribs ingot mould that can be used for directly forging hollow pole and direct poling.
Background technology
At present, in large-scale iron and steel processing and manufacturing enterprise, ingot shape adopts up big and down small many ribs ingot mould more, and the advantage of many ribs ingot mould is that area of dissipation is big, and surface of steel ingot Quench bed thickness can prevent surface of steel ingot to crack.Many ribs ingot mould is the mould that solidification of molten steel is shaped, and molten steel becomes steel ingot through cooled and solidified after injecting ingot mould.Aborning, many ribs ingot mould is the running stores of replaceability, and it not only has a direct impact the quality of steel, and is an important business accounting index.But the steel ingot of existing many ribs ingot mould production all can not better guarantee the internal structure and the surface quality of steel ingot.
The utility model content
The purpose of this utility model provides a kind of many ribs ingot mould that can better guarantee the internal structure and the surface quality of steel ingot.
For achieving the above object, the utility model adopts following technical scheme: a kind of many ribs ingot mould, comprise the column die body that has inner chamber, the intracavity section shape comprises the corner angle that the indent circular arc line that is uniformly distributed along the circumference and adjacent two circular arc lines form, and the outer wall cross sectional shape of die body is corresponding with the intracavity section shape consistent.
The corner angle that described adjacent two circular arc lines form are fillet.
When rolling steel ingot, the depth-width ratio of inner chamber is 2.5-4; When forging steel ingot, the depth-width ratio of inner chamber is 2.0-3.0.
When rolling steel ingot, the tapering of inner chamber is 2%-4%; When forging steel ingot, the tapering of inner chamber is 3%-5%.
The number of described corner angle is the even number greater than four.
The inscribed circle diameter d and the circumscribed circle diameter D of described indent circular arc line satisfy formula: (D
2-d
2)/d
2=0.8～1.0, and the degree of depth of indent circular arc line is 1.0～1.3% of die body length, and the radius of indent circular arc line is 10～15% of the steel ingot length of side.
The radius of corner r of described edges and corners satisfies formula: r=15% * d π/n, n are the ambiguous number of steel ingot.
The quantity of described corner angle is 4 or 8 or 10 or 12.
The beneficial effects of the utility model are: the outer wall of die body is corresponding with cavity shape consistent, can make the ingot mould heat radiation evenly, better prevents surface of steel ingot to crack, and adds the cooling capacity of large steel ingot, guarantees that the internal structure and the surface quality of steel ingot is good.Many cold junctions of inner chamber indent structure can be with the cast of bigger speed, and the concave edge steel ingot can not wave when mobile on mill table simultaneously, can correctly enter roll.Corner angle are all done circular, to reduce the fragile face that column crystal forms, prevent to produce chink.The depth-width ratio of steel ingot is very big to the quality influence of steel ingot, also is the major parameter of design ingot mould.The aspect ratio of rolling steel ingot is 2.5～4, and the depth-width ratio of forging steel ingot is 2.0～3.0, and the tapering of rolling steel ingot is 2～4%, and the tapering of forging steel ingot is 3～5%, increases depth-width ratio, can improve the productivity ratio of blooming mill.But depth-width ratio excessive (thin and grow), on when annotating owing to the splash of molten steel, can increase the surface lap and the rimhole of steel ingot.When making a bet owing to prolong the duration of pouring, in the mould cooling of molten steel face and oxidation serious, it is difficult that this not only can make liquid level rise, and occur defective such as skull patch easily.The utility model also has following beneficial effect: want can help in the casting process eliminating of gas in the steel and the come-up of non-metallic inclusion 1..2. the processing loss of accomplishing steel ingot is few, productivity ratio height, lumber recovery height.3. ingot mould is simple in structure, high life and be convenient to safeguard.

Fig. 2 is the vertical view among Fig. 1.
The specific embodiment
By a kind of many ribs ingot mould illustrated in figures 1 and 2, comprise the column die body 2 that has inner chamber 1, inner chamber 1 cross sectional shape comprises the corner angle that the indent circular arc line that is uniformly distributed along the circumference and adjacent two circular arc lines form, and the corner angle that adjacent two circular arc lines form are fillet, and the rib number is eight.When rolling steel ingot, the depth-width ratio of inner chamber 1 is 2.5-4; When forging steel ingot, the depth-width ratio of inner chamber 1 is 2.0-3.0.When rolling steel ingot, the tapering of inner chamber 1 is 2%-4%; When forging steel ingot, the tapering of inner chamber 1 is 3%-5%.The inscribed circle diameter d and the circumscribed circle diameter D of described indent circular arc line satisfy formula: (D
2-d
2)/d
2=0.8～1.0, and the degree of depth f(of indent circular arc line is an angle rib concave edge height) being 1.0～1.3% of die body 2 length h, the radius R of indent circular arc line (being steel ingot modular angle rib outer arc radius) is 10～15% of the die body 2 length h or the steel ingot length of side.The radius of corner r of edges and corners satisfies formula: r=15% * d π/n, n are the ambiguous number of steel ingot.Outer wall 3 cross sectional shapes of described die body 2 are corresponding consistent with inner chamber 1 cross sectional shape.The intracavity section parameter of many ribs ingot mould can be calculated by following formula:
V: steel ingot ingot health is long-pending: according to above formula, calculate base area up and down, again according to the terrace with edge computing formula, it is long-pending to calculate steel ingot ingot health: V=1/3 [S
On+ S
Down+ (S
On* S
Down)
1/2] * h.
Molten steel proportion is by 6.95～7.0t/ m
3Consider, can calculate steel ingot ingot body weight.
Certainly the utility model is not limited to above-mentioned form, and rib is counted n and also be can be four or ten or 12, can reach optimum efficiency.Certainly, also can be even number greater than four.
During use, rising head is set on ingot mould, and the cast molten steel, solidification of molten steel is shaped can form steel ingot.
