Description
Technical field
The invention belongs to soft magnetic materials field, and in particular to a kind of crystallization chill roll for preparing magnetically soft alloy thin slice.
Background technology
As new energy technology is greatly developed, the demand of soft magnetic materials increases substantially.The requirement of downstream client is also increasingly
Height, the common production technology mode for pouring ingot is smelted to intermediate frequency and puts forward challenge higher.Current intermediate frequency is smelted and commonly pours ingot
There is problem in magnetically soft alloy：Crystal grain easily grows into thick column crystal during casting solidification, the magnetically soft alloy of this crystal grain
Interval component segregation is serious, larger to soft-magnetic powder core performance impact.To improve the market competitiveness, it is necessary to improve the conjunction of intermediate frequency soft magnetism
Bronze end properties of product, reduce the appearance of component segregation phenomenon.
Magnetically soft alloy thin slice production technology is a technology in current soft magnetic materials research field more forward position, and it not only can
Simplify production process, and the sheet sheet product of gained can be directly entered ball milling operation.It is not required to follow from alloy molten steel ingot casting
→ Hubei Province is broken → a series of complex technique such as compound broken → screening → ball milling.Thin slice production technology is used simultaneously, and the time of ball milling is big
Amplitude shorten to the half of ingot casting powder, shortens the production cycle, lifts ball mill utilization rate, and specific energy consumption is reduced, with good
Good economic benefit.
In the production process of thin slice, molten steel rapid condensation flakiness how is allowed, the cooling water channel design of crystallization roll is to close
Key.The cooling effect of chill roll is bad, and the temperature of thin slice is too high, on the one hand needs to be cooled down for a long time in cooling storehouse, period
Smelting equipment can not carry out the work that feeds intake of next round, reduce the utilization rate of equipment；On the other hand, the too high thin slice of temperature is cold
But crystallization is also may proceed in storehouse, crystal is easily grown up, and cannot get preferable microcrystal.
The generally existing of current magnetically soft alloy thin slice production is not enough as follows：Crystallization chill roll internal structure is complicated, copper roller
Cooling effect is poor, and it is still very high to get rid of the temperature after flakiness, and the equipment on-line cooling stand-by period is long；The thin slice crossed after roller does not have also
Have and solidify completely, be easily bonded together in collector.The bad microstructure for causing rapid hardening alloy sheet of cooling effect is not
Ideal, sheet thickness is uneven, and crystal grain is uneven.
The content of the invention
The purpose of the present invention：A kind of high efficiency and heat radiation, simple structure, crystallization chill roll with low cost are provided.
Operation principle of the present invention：Under the double rotation structure of the dynamic copper roller of rolling core ribbon, the drive high pressure of the propeller blade of core is rolled
The continuous jet copper roller inwall of water, changes copper roller inwall cooling water maintenance turbulence state, the quickening of recirculated water flow velocity, rapidly so as to reach
Take away the purpose of copper roll temperature.
Technical scheme：A kind of crystallization chill roll for preparing magnetically soft alloy thin slice, including：Copper roller, rolling core,
Inlet opening, backwater hole, water inlet pipe, return pipe, roll shaft, rolling mandrel, left cover, right cover plate, water-cooled cavity, gear etc., wherein copper
Roller and rolling core are hollow-core construction；Rolling core is arranged on inside copper roller；Copper roller, rolling core and left and right cover plate composition closed water-cooled cavity knot
Structure；
Further, structure of the described rolling core exterior design into propeller blade；
Further, described rolling mandrel is connected by gear with roll shaft；
Further, described roll shaft is connected by belt pulley with drive device；
Further, described roll shaft rolls mandrel and rotates by gear driven.
By above-mentioned technical scheme, following advantage of the present invention and benefit：Simple structure of the present invention, it is easy to operate.It is logical
Cross the cooling of this programme device and get rid of thin slice, cooldown rate is high, and the crystal grain of rapid hardening alloy sheet is uniform, tiny, good product quality；
By the present apparatus throw away come web temperature dramatic decrease, solidify completely, into collector, after avoid thin slice bond, group
Poly-, caking phenomenon, the cool time of finished product shortens dramatically, and reduces the equipment on-line cooling stand-by period, improves the profit of equipment
With rate.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, but does not constitute limiting the scope of the invention.
In Fig. 1, Fig. 2, the present invention provides a kind of crystallization chill roll for preparing magnetically soft alloy thin slice by copper roller 1 and rolling core
2 are constituted, and wherein copper roller 1 and rolling core 2 is hollow-core construction；Rolling core 2 is arranged on inside copper roller 1；Copper roller 1, rolling core 2 are right with left cover 9
The structure of the composition closed water-cooled of cover plate 10 cavity 11；Structure of the rolling exterior design of core 2 into propeller blade；Rolling mandrel 8 passes through gear 12
It is connected with roll shaft 8；Roll shaft 7 is connected by belt pulley with drive device.
When this crystallization chill roll works, high-pressure cooling water enters water-cooled cavity 11 by water inlet pipe 5 and through inlet opening 3, in rolling
Under the drive of the propeller blade of core 2, the continuous inwall of spary copper roller 1, because copper roller 1 is different from the rotating speed of rolling core 2 so that waterway
Water in body 11 makees turbulent motion, and constantly copper roller 1 is washed away in rolling to the water in water-cooled cavity 11, then by backwater hole 4 by backwater
Pipe 6 loops back cooling-water machine.The cooled water of the temperature of copper roller 1 is constantly taken away like this, so as to reach the purpose of fast cooling.
The magnetically soft alloy liquid of melting rapid condensation under the drive of crystallization roll forms thin slice.
