Abstract
The utility model relates to a vacuum melting-refining furnace for producing neodymium, iron, boron and rare earth permanent magnetic alloy material and rare earth hydrogen-storage alloy material. The utility model is characterized in that: the lower part of a crucible (3) is fixed with a pair of rotating wheels; a cooling roll or a rotary disc with an intracavity is arranged below the rotating wheels; moreover, the intracavity of the cooling roll or the rotary disc is filled with flowing cooling water. The utility model aims to solve the problems such as poor uniformity of product, uneasy control of alloy thickness and easy blockage of nozzle during spraying process.
Description
The utility model relates to a kind of vacuum melting furnace of producing permanent-magnet rare-earth NdFeB alloy material and rare earth hydrogen storage alloy material.
The disclosed vacuum quick quenching furnace of the clear 63-333829 of Japanese patent laid-open 2-24730,2-247310 and Te Kai all is made up of single fast quenching roller, comprises upper and lower two continuous vacuum chambers in it, and smelting furnace is equipped with on top, and fast quenching equipment is settled in the bottom.The vacuum quick quenching furnace that Chinese patent z192105431.9 provides though the part furnace shell is removable and adopt wide fast quenching roller, can satisfies the requirement that big capacity amorphous or crystallite product lot quantity are produced, but still adopt single fast quenching roller.The weak point of said structure is:
1, the thickness of product depends primarily on the rotating speed of roller and nozzle gap and the nozzle bore size to runner, and adjustability is poor;
2, consistency of product is relatively poor, and is difficult for the product of spray greater than 100 μ m thickness;
3, because nozzle is less to the gap of runner, and nozzle bottom can not heat, easy plug nozzle in the spray process.
4, crystallization effect is bad, and the alloy material performance of making is undesirable.
At problem set forth above, the utility model provides a kind of vacuum quick quenching furnace, its objective is solve that consistency of product is relatively poor, problem that aspects such as the bad control of alloy thickness and the easy plug nozzle of spray process exist.
The utility model comes to be realized by the following technical programs:
A kind of vacuum quick quenching furnace, comprise that vacuum chamber double Shell, smelting furnace bottom is equipped with the crucible of nozzle, it is characterized in that: the fixing pair of turning wheels in the bottom of crucible, under this runner, be provided with a chill roll that has inner chamber, the inner chamber of chill roll is connected with mobile cooling water.
Chill roll can be replaced by the rotating disk of a rotation, also is provided with inner chamber in the rotating disk, and inner chamber is connected with mobile cooling water.
The utility model has the advantages that: because product thickness is the gap decision by two transfer rollers, so consistency of thickness is good, wide ranges.But steady production thickness is greater than the thin slice of 200 μ m.Owing in the bottom of crucible heater is housed, the bottom of crucible nozzle is higher than heater, and nozzle and crucible bottom temperature stabilization are not gaged somebody.
The utility model can be directly produced the fast quenching Nd Fe B alloys with the best speed of quenching, the cancellation crystallization process, and technology is simple, and good product consistency is produced the foundry alloy high conformity of sintered rare-earth permanent magnetic neodymium iron boron, and the oxytolerant performance is strong.Be applicable to the production of thin crystalline substance, crystallite and amorphous alloy material.
Fig. 1 has the structural representation of chill roll for the utility model;
Fig. 2 has the structural representation that cools off rotating disk for the utility model.
The utility model is described in further details by embodiment below in conjunction with accompanying drawing.
The utility model comprises vacuum chamber double Shell 1, middle band cooling water connects on the housing 1 and vacuumizes unit and air-charging and air-discharging system, is provided with smelting furnace 2, crucible 3 and two runners 4 in housing 1, change the gap of two runners 4, to satisfy the needs of producing the different-thickness product.This runner 4 times, be provided with a chill roll 5 that has inner chamber, the inner chamber of chill roll 5 is connected with mobile cooling water.Chill roll 5 can be replaced by the rotating disk 6 of a rotation, also is provided with inner chamber in the rotating disk 6, and inner chamber is connected with mobile cooling water.The rotating shaft of chill roll 5 or rotating disk 6 one ends extends to outside the stove.
The utility model course of work is as follows: at first body of heater is vacuumized or charges into protective gas, smelting furnace is heated.Molten alloy heats crucible simultaneously.Start runner.After treating that alloy melting reaches requirement, good alloy is poured in the crucible with ironing refining, flows in the gap of rotating runner 4 through the nozzle bottom the crucible, makes fragment.In cooling, make product after the collection by chill roll 5 or rotating disk 6.
Claims (2)
1, a kind of vacuum quick quenching furnace, comprise that vacuum chamber double Shell (1), smelting furnace (2) and bottom be equipped with the crucible (3) of nozzle, it is characterized in that: fixing pair of turning wheels (4) in the bottom of crucible (3), under this runner (4), be provided with a chill roll (5) that has inner chamber, the inner chamber of chill roll (5) is connected with mobile cooling water.
2, vacuum quick quenching furnace according to claim 1 is characterized in that: chill roll (5) can be replaced by the rotating disk (6) of a rotation, also is provided with inner chamber in the rotating disk (6), and inner chamber is connected with mobile cooling water.
