Speed, is to make up be difficult on solder composition amorphous overriding concern of the chemical conversion with this short slab.The heat exchange of chill roll refers to that melt coagulates
Solid heat quickly taken away via the cooled water of copper roller, and the internal watercourses with strong exchange capability of heat chill roll are designed, it is involved
Be how to allow cooling water quickly through this problem in science of chill roll.
The content of the invention
The purpose of this utility model is directed to during vacuum quick quenching prepares specific alloy Non Crystalline Foil band, due to alloy itself
Amorphous formation ability is not strong, it is necessary to improve freezing rate, and current chill roll internal watercourses design has exchange capability of heat
A kind of not enough situation, there is provided rotation chill roll of the fast quenching with strong exchange capability of heat with Multichannel Parallel spiral channel.
To achieve these goals, the utility model provides following technical scheme：
The utility model provides a kind of fast quenching rotation chill roll with strong exchange capability of heat, and it includes water-cooled copper roller 1, core bucket
2nd, water inlet 3 and delivery port 4；Core bucket 2 is arranged on inside water-cooled copper roller 1, and water inlet 3 and delivery port 4 are separately positioned on water-cooled copper
The axial left and right of roller 1 two ends.
The spiral channel 5 that multichannel is parallel to each other is provided with the inwall that the water-cooled copper roller 1 is contacted with cooling water.
The pitch S of the spiral channel 5 is 50~100mm.
The cross section of the spiral channel 5 is half elliptic, semicircle, triangle, rectangle, trapezoidal one kind.
When the cross section of spiral channel 5 is half elliptic or rectangle, the ratio of width D/height h is 2~3.5.
The water-cooled copper roller 1 has the spiral channel 5 that 3~5 roads are parallel to each other.
Compared with prior art, the beneficial effects of the utility model are：
Cooling water is distributed rapidly to parallel multichannel water channel, respectively along spiral after entering the utility model rotation chill roll
Water channel can take away more heats quickly through water-cooled copper roller in the short time, play the purpose of high efficient heat exchanging.
The utility model have well promote and practical value, can prepare aerospace field urgent need, do not possess
The alloy system Non Crystalline Foil band of strong amorphous formation ability, can produce good economic benefit and society to imitate after extensive popularization and application
Benefit.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figure 1, the fast quenching rotation chill roll with strong exchange capability of heat of the present utility model includes water-cooled copper roller 1, core
Bucket 2, water inlet 3 and delivery port 4；Core bucket 2 is arranged on inside water-cooled copper roller 1, and water inlet 3 and delivery port 4 are separately positioned on water-cooled
The axial left and right of copper roller 1 two ends.
As shown in Figure 2 a and 2 b, on the inwall that the water-cooled copper roller 1 is contacted with cooling water multichannel is provided with to be parallel to each other
Spiral channel 5, cooling water is distributed rapidly after entering water-cooled copper roller 1, and along Multichannel Parallel spiral channel 5 quickly through water
Cold copper roller 1, can take away more heats in the short time, play the purpose of high efficient heat exchanging.Preferably, the water-cooled copper roller 1 has 3
