Abstract
The invention aims to disclose a round steel ingot pouring mould capable of decreasing cooling speed difference of molten steel in a cavity and belongs to the field of round steel ingot production. The round steel ingot pouring mould comprises a bottom plate and a mould body with a cavity, wherein the mould body is disposed on the bottom plate, the cavity is formed by penetration from the upper end face of the mould body to the lower end face thereof, and the bottom plate is provided with a plurality of molten steel ascending holes which are evenly distributed around an axis of the cavity of the mould body. The round steel ingot pouring mould has the advantages that since a distance between each stream of molten steel and the center of the cavity is kept, the temperature of the molten steel in the cavity is dispersed, the temperature of the molten steel in the center of the cavity is lowered effectively to make the difference between the internal and external molten steel temperatures of the cavity decrease, the cooling speed difference of the molten steel in the cavity declines, the decrease range of the molten steel liquid level after gradual cooling of internal molten steel is narrowed, the degree that the steel ingots have voids internally is lowered effectively and the steel ingot quality is improved.
Description
Technical field
The present invention relates to a kind of produce round ingot pour mold.
Background technology
The lower casting mode of existing round ingot is that molten steel is entered in casting model chamber, then by liquid through pouring channel
Gradually liquid is cooled to, ultimately forms round ingot.But, molten steel is entered and is remained static in die cavity, is then gradually cooled to
Solid-state, as casting die has a heat absorption capacity, and pours outer wall and the atmosphere of mold, is conducive to radiating, therefore, near pouring mold
The molten steel of inwall rapidly cool to form chill, and the molten steel rate of cooling of inside is much smaller than outside molten steel, internal molten steel by
After gradually cooling down, liquid steel level declines, and space occurs in inside, affects ingot quality.
Content of the invention
The technical problem to be solved is to provide a kind of round ingot for reducing molten steel rate of cooling difference in die cavity
Pour mold.
The technical solution used in the present invention is：Round ingot pour mold, including base plate and the die body of belt type cavity, the die body
It is arranged on base plate；The die cavity runs through lower surface by the upper surface of die body；The base plate is provided with multiple molten steel rise hole, many
Individual molten steel rise hole is uniformly distributed around the axis of die body die cavity.
Further, the plurality of molten steel rise hole die body die cavity from the bottom to top is centroclinal, and each molten steel rises
The gradient in hole is consistent.
Further, the plurality of molten steel rise hole is from the bottom to top to the sidewall slope of die body, and each molten steel rise hole
Gradient be consistent.
Further, the gradient of the molten steel rise hole is 0-1%.
Further, molten steel cache slot is additionally provided with the base plate, and the molten steel cache slot is just being located at molten steel rise hole
Lower section is simultaneously connected with molten steel rise hole.
Further, the molten steel cache slot is in a ring.
Further, the base plate is provided with along die body axially to prominent round platform in die cavity, the outer surface of the round platform
It is adapted to the inner surface of die cavity.
The invention has the beneficial effects as follows：The present invention, as per share molten steel is all distance away with die cavity center, dispersion
In die cavity, the temperature of molten steel, effectively reduces the temperature of die cavity center molten steel, makes die cavity internal layer liquid steel temperature and outside steel
Temperature difference between coolant-temperature gage reduces, and in die cavity, molten steel rate of cooling subtractive is little, reduces molten steel after internal molten steel is gradually cooled down
The amplitude that liquid level declines, effectively reduces the degree for occurring space inside steel ingot, improves ingot quality.

In figure, base plate 1, die body 2, die cavity 3, molten steel rise hole 4, molten steel cache slot 5, round platform 6.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
Round ingot pour mold, as Figure 1-Figure 4, including the die body 2 of base plate 1 and belt type cavity 3, the die body 2 is arranged
On base plate 1；The die cavity 3 runs through lower surface by the upper surface of die body 2；The base plate 1 is provided with multiple molten steel rise hole 4,
Multiple molten steel rise hole 4 are uniformly distributed around the axis of 2 die cavity 3 of die body.
Due to arranging multiple molten steel rise hole 4 on base plate 1, then, molten steel just has multiple passages to enter inside die cavity 3,
And molten steel rise hole 4 is uniformly distributed around the axis of 2 die cavity 3 of die body, then, also around the axle of die cavity 3 during molten steel entrance die cavity 3
Line is uniformly distributed, i.e. per share molten steel is all distance away with 3 center of die cavity, however, during molten steel injection die cavity 3, molten steel post
Temperature highest, after entering die cavity 3, molten steel post disperses, and molten steel is to around trickling, and molten steel radiates, and temperature reduces.Due to per share steel
Water is all distance away with 3 center of die cavity, has disperseed the temperature of molten steel in die cavity 3, effectively reduces 3 center steel of die cavity
The temperature of water, reduces the temperature difference between 3 internal layer liquid steel temperature of die cavity and outside liquid steel temperature, molten steel rate of cooling in die cavity
Subtractive is little, reduces the amplitude that after internal molten steel is gradually cooled down, liquid steel level declines, effectively reduces inside steel ingot and space occur
Degree, improve ingot quality.
As molten steel is entered behind 3 inside of die cavity, in relative static conditions, it is unfavorable for radiating, in order to help radiate, enters one
Step, centroclinal, and the inclination of each molten steel rise hole 4 of the plurality of molten steel rise hole 42 die cavity 3 of die body from the bottom to top
Degree is consistent.2 die cavity 3 of die body from the bottom to top of molten steel rise hole 4 centroclinal, then molten steel is just inclined in injection die cavity 3,
Per share molten steel relative impact, forms stirring to the molten steel in die cavity 3, is conducive to the heat exchange of molten steel and outer layer molten steel, accelerates
Radiating.
Certainly, the plurality of molten steel rise hole 4 can also be from the bottom to top to the sidewall slope of die body 2, and on each molten steel
The gradient for rising hole 4 is consistent.
Preferably, the gradient of the molten steel rise hole 4 is 0-1%.
In order that the speed of molten steel that passes through of each molten steel rise hole 4 and flow are consistent, it is preferred that the base plate 1
On be additionally provided with molten steel cache slot 5, the molten steel cache slot 5 is located at the underface of molten steel rise hole 4 and is connected with molten steel rise hole 4
Logical.After molten steel fills up molten steel cache slot 5, molten steel flows into die cavity 3 through molten steel rise hole 4 again automatically.
In order to reduce amount of storage of the molten steel in molten steel cache slot 5, it is to avoid molten steel is wasted, it is preferred that the molten steel cache slot 5
In a ring.
Match with base plate 1 for the ease of die body 2, so as to coordinate every time make, multiple molten steel rise hole 4 can accurately be around mould
The axis of 2 die cavity 3 of body is uniformly distributed, it is preferred that the base plate 1 is provided with along die body 2 axially to prominent round platform 6 in die cavity 3,
The outer surface of the round platform 6 is adapted to the inner surface of die cavity 3.
