Description
Technical field
The utility model belongs to metal surface chemical treatment and metal material DIFFUSION TREATMENT technical field, specifically, this
Utility model is related to a kind of non-continuous zinc penetration equipment of airtight passage formula.
Background technology
Zincizing is to obtain the surface protection technique of zinc-iron alloy layer in surface of workpiece with thermal diffusion method, is by zincizing
Agent and metal works etc. are co-located in Sherardizing furnace, and under predetermined technological temperature, zinc atom is internally permeated by surface of workpiece,
Iron atom then spreads from inside to outside simultaneously, whereby, one layer of uniform zinc-iron compound, i.e. zincizing is formed on metal works top layer
Metal works are realized cathodic protection by layer by zinc coat.
At present, the powder zincizing processing to surface of workpiece, is mainly carried out, specifically under closed vacuum environment
There is following two ways：
First, using Sealing furnace " static state " zincizing, i.e., metal works, zinc powder and various penetration-assisting agents are loaded in Sealing furnace, order
Metal works are embedded in compound powder, after being heated to predetermined technological temperature, held for some time, realize that diffusion type oozes under " static state "
Zinc, after zincizing terminates, come out of the stove after cooling to predetermined temperature.
This kind of zincizing mode, due to needing to carry out filling out stove seal operation before zincizing, Kaifeng is needed to come out of the stove again after treatment,
Therefore, its handling process can only be the mode by stove processing, and each stove is required to heat up before treatment in addition, and drops after treatment
Temperature, the whole processing time of each stove take around 6~8 hours, and its zincizing processing ineffective time cost is long, causes at technique
Reason efficiency is low, and heating, cooling process wastes substantial amounts of time, the energy and labour.
Second, use rotary Sherardizing furnace " dynamic " zincizing.Rotary Sherardizing furnace is mainly by support roller, burner hearth body, heating unit
Part, hermetic rotary zincizing tank, Rolling motor composition；During operation, by metal works, zinc powder, various auxiliary agents, inertia impact media
It is fitted into the lump in hermetic rotary zincizing tank, then closed zincizing tank lifting is put into burner hearth body, and be set up in both sides
On support roller, the rotation of zincizing tank is driven by Rolling motor, while zincizing tank is heated, handles the scheduled time at a predetermined temperature
Afterwards, heating element heater is closed, zincizing tank furnace cooling to predetermined temperature, Rolling motor is then turned off and hangs out zincizing tank, finally beat
Open the workpiece after zincizing tank taking-up processing.When metal works are of large quantities, also a large amount of workpiece can be once dispensed to several zincizings
In tank, several zincizing tanks are handled in lifting to mesh belt transmission formula Sherardizing furnace simultaneously, and concentrate and carry out lower tank pickup.
This kind of zincizing mode, by the rolling of zincizing tank so that mechanical friction is formed between zinc particle and metal works,
To accelerate the reaction of zinc atom and surface of workpiece atom, reach the effect that mechanical auxiliary oozes, still, rotating speed is rolled by zincizing tank
Limited, the kinetic energy of acquisition is small, it is impossible to effectively excite the activation energy of zinc atom, be additionally, since before zincizing need into
Row fills out stove seal operation, needs Kaifeng to come out of the stove again after treatment, and therefore, its handling process can only be handled by stove, in addition
Each stove is required to heat up before treatment, and cools after treatment, and it is small that whole processing time of each stove part stills need 5~6
When, it is still limited to improve zincizing efficiency effect by way of machinery rotation is helped and oozed, it is difficult to meet serialization, extensive
The beat requirement of production.
, can be by addition, though rotary Sherardizing furnace is by the structure that separates hermetic rotary zincizing tank and burner hearth
The rolling of zincizing tank improves zincizing efficiency, still, because the rotary motion of hermetic rotary zincizing tank is so that it can not realize interior
Portion is heated, and can only be by the heating element heater between burner hearth and hermetic rotary zincizing tank, and first hermetic rotary is oozed
Zinc can is externally heated, then delivers heat to its internal metal works by zincizing tank again, this is resulted in, heating element heater spoke
The heat penetrated can consume a part by flue, it is impossible to fast and effeciently conduct to metal works, extend heating metal works institute
The time (while also extending temperature fall time) needed, reducing efficiency so that the disposed of in its entirety time of each tank is elongated, meanwhile,
Heating and cooling zincizing tank again because adds additional the loss of heat and caused by energy waste, and add dirty to the heat of environment
Dye.
It follows that existing zincizing technology, due to equipment and the limitation of technique, it can only divide stove to handle, and at single stove
Reason amount less, the time length, with every stove handle 300~800 kilograms, 6~8 hours per furnace gauge calculate, at most can only also handle 3 tons daily,
Production efficiency is very low, it is impossible to meets the needs of large-scale production, but also is difficult to ensure that the homogeneity of product quality, together
When, its metal works shove charge, frequent operation of coming out of the stove, labour's consumption is big, moreover, each stove is required to heating, cooling, it is not only unrestrained
The substantial amounts of energy is taken, it is also possible to the pollution to environment can be brought, do not meet the environmentally friendly trend of energy-saving and emission-reduction.
