Processed in technology amorphous get rid of band chill roll cooling effect is bad, the problem of structure is complicated.
In order to achieve the above object of the invention, the technical solution adopted in the utility model is as follows:
There is provided a kind of air-cooled chilling roller comprising seal case and be rotatably fixed on the intracorporal roll body of seal box, roller
The copper sheathing that body includes roller core and is coaxially coated on roller core lateral wall, is circumferentially evenly distributed on roller core and several is in around its axial direction
One side of the copper sheathing adjacent to roller core is led in spiral air duct, air duct.The air inlet in air duct is located on the end face of roller core, roller core and copper
Be provided between set be connected to air duct let out air port.
Further, air port axially penetrating through along roll body is let out, that is, there are outlet air in the two sides for letting out air port towards copper sheathing, by letting out
The air-flow in air port come guarantee the molten metal being ejected on copper sheathing outer surface in cooling procedure will not overflow go out other than copper sheathing, from
And improve the yield rate that amorphous gets rid of band.
Further, the air outlet in air duct leads to the middle part for letting out air port axial direction, and air outlet is perpendicular to itself and copper sheathing contact position
Section.High-pressure liquid gas sprays to copper sheathing and radiates around from centre, so that amorphous gets rid of the cooling of band more evenly, mentions
High Forming Quality.
Further, aperture of the air duct from air inlet to air outlet is sequentially increased.Roll body during rotation, seal case
Interior high-pressure liquid gas enters in air duct from air inlet, and increases air-cooled acting surface with the increase in air duct aperture
Product, to accelerate cooling velocity, improves radiating efficiency.
Further, copper sheathing is chromium-zirconium-copper set.Chromium-zirconium-copper has the advantages that thermal conductivity is good, hardness is high, softening temperature is high, energy
The cooling velocity of molten metal is enough improved, and the molten metal for avoiding high temperature damages roll body.
Further, the material of roller core is aluminium.The thermal conductivity of aluminium is good, can accelerate the melting gold on cooling injection to copper sheathing
The cooling of category.
Further, the coaxial fixing sleeve of roll body loaded in rotation axis, be fixed on bracket by bearing by the both ends of rotation axis,
The bottom end of bracket is fixedly connected on the bottom surface of seal case.
The utility model has the following beneficial effects: the contact by using the high copper sheathing of thermal conductivity as roll body with molten metal
Face can accelerate the cooling velocity of molten metal；Spiral air duct is set in roller core, high-pressure liquid gas is passed through in air duct
Body accelerates the cooling of molten metal, and spiral air duct increases heat dissipation area, can further speed up cooling velocity.
Chilling roller in this programme is placed in seal case, high-pressure liquid gas is sent into seal case, in chilling
During roller high-speed rotation, gas can be recycled constantly automatically to be entered the air duct air port Hou Congguo from air inlet and is discharged to seal case
Interior process saves the usage amount of gas；And the intracorporal high-pressure liquid gas of seal box can be avoided molten metal in urgency
Cold get rid of at amorphous is oxidized with during, improves the yield rate that amorphous gets rid of band.

Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the column of protection.
As shown in Figure 1 and Figure 2, which includes seal case 1 and is rotatably fixed in seal case 1
Roll body 2, the coaxial fixing sleeve of roll body 2 is loaded in rotation axis 3, and the both ends of rotation axis 3 are fixed on bracket 5 by bearing 4, bracket 5
Bottom end be fixedly connected on the bottom surface of seal case 1.The high speed rotation under the drive of power device of rotation axis 3, and drive roller
2 high speed rotation of body.The top of seal case 1 is provided with the nozzle 11 of alignment roll body, and molten metal is sprayed to roll body 2 by nozzle 11
On external cylindrical surface.Be provided with the air inlet pipe 12 high-pressure liquid gas being sent in seal case 1 on the side wall of seal case 1.
