Technical field
The utility model belongs to salt bath nitriding technical field, is related to the deslagging device in salt bath nitriding field, and in particular to
A kind of nitriding salt bath deslagging device.
Background technology
In salt bath nitriding technology, the cleaning for how ensuring salt bath is the key of the technology, and reliably and thoroughly remove the gred work
Skill, then be to ensure that the critical process of salt bath cleaning.The clinker of nitriding salt bath can macroscopically be divided into thick slag and fine slag.Thick slag is easy to
Sink to the bottom, will not suspend and flow with salt bath in nitriding production process, will not be contacted with workpiece, while thick slag is easy to by common
Slagging-off means are disposed, therefore are very littles to directly affecting for nitriding quality.And fine slag can be then suspended in salt bath with salt
The flowing of bath and flow, can and the various positions of workpiece come in contact, when there is contact, what is often discharged in salt bath is various free
Gas just forms microbubble in contact point aggregation release, so contact position formation " metal-saline solution-microbubble " " Gu-
Liquid-gas " three-phase structure.This three-phase structure once formed, will influence nitrogenize quality, for example formed etch pit, produce piebald,
Produce the nitridation defect such as uneven point of nitriding.Therefore, fine slag is to influence the key substance of salt bath nitriding quality.
The composition of fine slag is mainly ferromagnetic material and a small amount of graphite particle.Ferromagnetic material has suspension iron ion, suspension
Iron-nitride, suspension ferriferous oxide etc..These suspension ferromagnetic materials are because extremely trickle, it is easy to flowed with salt bath, because
This is very difficult to remove by general slagging-off means.
The deslagging device of current salt bath nitriding is mainly screen pack and sediment disk, and screen pack slagging-off is easy to operate, quick, but
Thick slag can only be filtered, to fine slag without positive effect, and sediment disk can filter most of clinker, including fine slag, but need a few hours
The sediment time, when pulling sediment disk out, clinker can be revealed again, secondary pollution salt bath, and during sediment need block production,
Production, inefficiency must be stopped when dragging for slag.
Most of composition of clinker is ferromagnetic material in nitriding salt bath, but in the operating temperature range of nitridation salt bath
(500-600 DEG C), common magnetisable material, such as common permanent magnet, its magnetic can all decline or even be demagnetized.Therefore, magnetic
Absorption clinker is because high temperature demagnetizes and is not successfully applied.

Clinker in bath can be adsorbed, and reach the effect of slagging-off, and removed the salt bath after clinker and then flowed back in nitridation salt bath.This reality
Salt bath is removed the gred during circulation with new, and clinker when following salt bath to flow can close to magnetic pole and by
Absorption, is conducive to thorough removing slag, and during salt bath circulation slagging-off, production can be carried out continuously, and be substantially increased
Production efficiency.
The applied magnet is by ungulate iron core and is arranged on ungulate iron core and makes the magnetized magnetic devices structure of ungulate iron core
Into.Using ungulate iron core, and on ungulate iron core, setting can make its magnetized magnetic devices so that ensure ungulate core magnetism performance
While, magnetic devices are not contacted directly with high-temperature salt bath, so that the high temperature demagnetization influence of salt bath is avoided, and ungulate iron core can be
More uniform magnetic field is formed between magnetic pole, can also make magnetic line of force formation path, strengthen suction.
The magnetic devices are permanent magnet or coil.Permanent magnet can remain ungulate iron core to be magnetic, and coil is then
The size of magnetic field intensity can be adjusted as needed.
Ungulate iron core between the magnetic devices and magnetic pole is provided with cooling down bag, it is to avoid salt bath high temperature is conducted into magnetic
Property device at, influence the magnetic efficiency of ungulate iron core.
Screen pack is provided with deflector below the magnetic pole, slagging-off effect can be further ensured that, it is to avoid by ungulate iron
The attached clinker of wicking is fallen into nitridation salt bath again, causes secondary pollution.
The screen pack is asbestos paper or wire netting.
