Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of amorphous ribbon production, in particular to a cooling roller guide device for amorphous ribbon production. Background Art
[0002] Molten steel cools rapidly at a rate of millions of degrees per second, dropping from 1300°C to below 200°C in just one thousandth of a second. The cooling process is so rapid that the atoms don't have time to rearrange themselves before solidifying, leaving the alloy with a random arrangement of atoms. This creates an amorphous alloy and forms amorphous ribbon.
[0003] In the production of amorphous ribbons, cooling rollers are required for high-speed cooling. The current cooling water path structure in the cooling roller core is that the cooling water enters directly from the center hole of the main shaft, then exits from the radial holes of the main shaft and enters the radial holes in the support disk. Then, the cooling water enters the annular channel under the copper roller from the radial holes of the support disk to cool the copper roller. Since the number of radial holes in the support disk is greater than the radial holes on the main shaft, there is also an annular space between the radial holes, and the cooling water flows from this annular space to multiple radial holes. Since the cooling roller rotates at high speed, the angular velocity of the cooling water rotating around the main shaft axis needs to be continuously increased in the process of entering the radial holes to keep up with the angular velocity of the radial holes, so that it can smoothly enter the radial holes.
[0004] In the traditional water channel structure, in the annular space, only the friction of the space side wall on the water body drives the water flow to rotate. Therefore, the angular velocity of the water flow lags far behind the angular velocity of the radial holes, which causes resistance to the water flow, resulting in an increase in the pressure difference between the inlet and outlet of the water channel, which not only increases energy consumption, but also attenuates the cooling effect of the cooling roller. Summary of the Invention
[0005] (1) Technical problems solved
[0006] In response to the deficiencies in the prior art, the present invention provides a cooling roller guide device for amorphous ribbon production, which has the advantages of greatly reducing the flow resistance of cooling water, reducing mechanical energy dissipation and temperature rise due to fluid viscosity, and greatly reducing the pressure difference in the cooling roller water channel, thereby improving the cooling effect of the cooling roller. It solves the problem that the traditional water channel structure is in an annular space, and only the friction force of the side wall of the space on the water body drives the water flow to rotate. Therefore, the angular velocity of the water flow lags far behind the angular velocity of the radial holes, which causes resistance to the water flow, thereby increasing the pressure difference at the inlet and outlet of the water channel, which not only increases energy consumption, but also causes a decline in the cooling effect of the cooling roller.
