The centering type crystallizer periphery of the present embodiment is provided with electromagnetic stirrer coil 200, electromagnetic agitation line in the present embodiment
The frequency of circle 200 is 2-10Hz, and the preferred 5Hz of the present embodiment, the sphere of action of electromagnetic stirrer coil 200 is upper crystallizer 110
In slag bath 530.In the slag bath 530 of upper crystallizer 110, pass through the stirring action of electromagnetic stirrer coil 200 so that metal consumable
The molten metal that remelting is formed in slag bath 530 of electrode 510 stirs, and makes molten metal being uniformly distributed in slag bath 530, promotes
Rolling face material can more uniformly be coated in 520 surface of roller core.
In the upper crystallizer 110 of the present embodiment, the open side 112 is equipped with close to the side of metal consumable electrode 510 and leads
Flow dam 111, water conservancy diversion dam 111 is arc, in the present embodiment, 111 center of water conservancy diversion dam 510 axle center of metal consumable electrode with
On the straight line in lower 120 axle center of crystallizer, the arc length of water conservancy diversion dam 111 is the 1/4 of place circumference, and water conservancy diversion dam 111 is high
Spend 1/4 for lower 120 internal diameter of crystallizer.
The remelting in slag bath 530 of metal consumable electrode 510 goes out 520 direction of the roller core expansion into lower crystallizer 120 after molten metal
It dissipates, after adding in water conservancy diversion dam 111, molten metal is impacted in water conservancy diversion dam 111, due to 111 guide functions of water conservancy diversion dam, a part
Both sides flowing of the molten metal along 111 arcuate directions of water conservancy diversion dam to water conservancy diversion dam 111, makes molten metal flow to farther place, accelerates to roll
Roller roller core 520 deviates from the coating of 510 face roll working lining of metal consumable electrode, and rolling face material is promoted more uniformly to coat
On 520 surface of roll roller core.
Vibrating mechanism 121 is equipped with outside 120 upper end of lower crystallizer of the present embodiment, the sphere of action of vibrating mechanism 121 is molten
540 position of pond, vibrating mechanism 121, around setting, are percussion vibration, after molten drop drops down onto molten bath 540 in lower 120 outer shroud of crystallizer
Solidification, crystal inside start forming core and grow up, and 121 percussion vibration of vibrating mechanism effect, vibration wave is passed in molten bath 540, and part is just
It is broken after the texture grown up is vibrated, generate more forming core cores, the better texture of forming properties.
The bottom water tank 300 of the present embodiment is arranged on the lower section of lower crystallizer 120, is connect with roller core 520, the present embodiment midsole
