Mass ratio is 1:1～1.5:1, so arranges, and one is easy for the heat radiation of liquid rare earth magnesium ferrosilicon alloy,
Two is that 1 need of alloy alms bowl hold a certain amount of liquid rare earth magnesium ferrosilicon alloy, and its volume is not required to too
Greatly, thus without the waste causing material.
Further, step 1) described in alloy alms bowl 1 remaining temperature after drying be to pour liquid into when 50～80 DEG C
Rare earth magnesium ferrosilicon alloy, it is ensured that in alloy alms bowl 1, noresidue moisture just can pour liquid rare earth ferrosilicomagnesium into
Alloy.Pour into when 50～80 DEG C, also allow for the cooling of liquid rare earth magnesium ferrosilicon alloy.
Further, step 2) in rare earth magnesium ferrosilicon alloy injection cold water or injection high-pressure atomization gas carry out
During Quench, the upper end of alloy alms bowl 1 is provided with an aqueous vapor protective fence 2, is so possible to prevent current or mist
Spill over outside outside activating QI, affect the production environment in workshop.
Further, described alloy alms bowl 1 is provided with suspension ring upset handle 11 and fin 12, with more in conjunction
The handling of gold alms bowl 1 and heat radiation, fin 12 contributes to the quick heat radiating of liquid rare earth magnesium ferrosilicon alloy.
Further, step 2) in naturally cool to again after rare earth magnesium ferrosilicon alloy is cooled to about 300 DEG C
Room temperature.Therefore, when Quench, it is not required to spray cold water to liquid rare earth magnesium ferrosilicon alloy always
Or injection high-pressure atomization gas, only need to spray a period of time, allow its natural cooling the most again, the most permissible
Effectively save resource.
Further, step 2) in be provided above aqueous vapor collecting-distributing device 3 at alloy alms bowl 1 when carrying out Quench,
Aqueous vapor collecting-distributing device 3 can use the equipment of aerator etc, the aqueous vapor produced during Quench to be taken away.
The operation principle of the present invention is as described below: nodulizer is to be bound up by multiple element, its metallographic
The polynary complexity of structure, respectively shrinks difference mutually in cooling procedure, cracks, cold treatment speed and crackle journey
Degree is directly proportional, and nodulizer is interval in different temperatures, carries out Quench process so that it is reach basic divided
State is aided with mechanism (only needing 0.5～1 kilogram of impulsive force), just can form various required granularity
Nodulizer.
In sum, the main points in the present invention have:
