Iron boron raw material is poured into after raw material melting in sprue cup, and the discharge port of sprue cup lower part connects chill roll, chill roll high speed rotation
Melting charge is quickly cooled down and is formed and gets rid of strap and enters in turntable, turntable stirring, which further crushes, gets rid of strap.But this biography
The method of system, since turntable is also at high-speed rotating process, it is easy to strap will be got rid of and throw away turntable, caused to miscellaneous equipment
Damage, meanwhile, it is directly got rid of from chill roll also very high into the product temperature to turntable, it is easy to be adhered phenomenon, influence to get rid of
The quality of strap.
Invention content
In order to which final result is cooling in the prior art and gets rid of the problem of strap throws away turntable, the utility model proposes a kind of rapid hardenings

In order to further decrease the temperature that atomizer sprays water mist, accelerates cooling process, be additionally provided on the water inlet pipe
Freeze unit.
The baffle or the angle of its extended line and turntable are 55-70 ° as a preferred implementation manner, preferably, institute
It is 60 ° to state baffle or the angle of its extended line and turntable.
It is thrown away from turntable to effectively prevent getting rid of strap, the height of turntable side wall is not less than the radius of the turntable.
The utility model using the above structure, after what is flown out from chill roll gets rid of strap and flies out, can first under baffle
Square convex block collision, realizes and crushes, be then return in turntable and be further crushed cooling, is not easy anti-life and is adhered phenomenon；In addition, originally adopting
Protection gas is cooled down with atomization cooling mode, cooling efficiency is substantially increased, while heat exchanger is omitted, drops significantly
Low power consumption.
