Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
Round steel ingot mould, the die body 1 including belt type cavity as depicted in figs. 1 and 2, the die body 1 includes upper surface 11, lower surface
12nd, lateral wall 13 and madial wall 14；Multiple stomatas 2 are provided with the lateral wall 13 of die body 1, multiple stomatas 2 are located at 1 time mouth of die body
Place, and it is circumferential uniform along die body 1；It is additionally provided with die body 1 with the equivalent of stomata 2 between lateral wall 13 and madial wall 14
Heat dissipation channel 3, the heat dissipation channel 3 extends to upper surface 11 by lower surface 12；The heat dissipation channel 3 is corresponded with stomata 2
It is connected.
The round steel ingot mould, when die cavity of the pouring molten steel to die body 1, most of heat by the madial wall 14 of die body 1 to
External diffusion, enters into heat dissipation channel 3, and the heat part in heat dissipation channel 3 is along heat dissipation channel 3 upwards by the row of upper surface 11
Go out, partly spread by lateral wall 13, partly discharged by stomata 2 downwards by heat dissipation channel 3, heat is arranged by mulitpath
Go out, accelerate the radiating rate of the outer layer molten steel in die cavity, be conducive to the molten steel of outer layer to rapidly cool to form chill, outer layer steel
The radiating rate of water is improved, and is conducive to the quick outer layers molten steel of heat of internal layer molten steel to transmit, so as to accelerate internal layer steel
The radiating rate of water, and then the thickness of chill is improve, thicker chill is more beneficial for bearing what is produced during pouring molten steel
Static pressure, so as to be more beneficial for reducing the face crack of steel ingot, improves the surface quality of steel ingot.
In order to further speed up radiating rate, it is preferred that including cooling system 4, the cooling system 4 includes air blower 41
With air inlet supervisor 42；The air inlet is responsible for 42 one end and is connected with the gas outlet of air blower 41, and the other end is connected with and the equivalent of stomata 2
Air intake branch 43；The air intake branch 43 is corresponded and is installed on stomata 2.Sky is blasted to heat dissipation channel 3 by air blower 41
Gas, accelerates the velocity of liquid assets of air in heat dissipation channel 3, and the heat for enabling molten steel to give out is discharged rapidly, so as to accelerate
Radiating rate.
Because in pouring molten steel, the heat that molten steel is distributed is very big, the heat distributed in order to avoid molten steel is to working environment
Impact, it is preferred that the cooling system 4 also includes exhaust supervisor 44, gas tank 46 and connecting tube 47；The exhaust supervisor 44
One end is connected with gas tank 46, and the other end is connected with the going out gas branch pipe 45 with the equivalent of heat dissipation channel 3, a pair of the going out gas branch pipe 45 1
The upper port of heat dissipation channel 3 should be installed on；The air inlet of the air blower 41 is connected by connecting tube 47 with gas tank 46；In connection
The first refrigerator 48 is additionally provided with pipe 47.Gas tank 46 is used to collect the hot-air of the discharge of heat dissipation channel 3, and the first refrigerator 48 pairs
The hot-air of the discharge of heat dissipation channel 3 is cooled down, and the air for enabling gas tank 46 to collect is recycled, so as to reduce to environment
Influence.
To cold air is input into heat dissipation channel, be conducive to heat exchange, can more accelerate radiating, therefore, it is preferred that in air inlet master
Pipe 42 is provided with the second refrigerator 49.Second refrigerator 49 plays a part of cooling air, make enter heat dissipation channel 3 air be
Cold air.
Because molten steel is slower than lower mouth in the poring rate suitable for reading of die body 1, radiating rate is slow, easily cracks, in order to
Accelerate the radiating rate suitable for reading of die body 1, chill is consistent in the ability that die body 1 bears static pressure everywhere, further,
By the direction of lower surface 12 to upper surface 11, the section of the heat dissipation channel 3 gradually increases.
