Description

A kind of mechanical energy auxiliary zinc penetration equipment and technique
Technical field
The invention belongs to metal surface chemical treatment and metal material DIFFUSION TREATMENT technical fields, specifically, of the invention It is related to a kind of mechanical energy auxiliary zinc penetration equipment and mechanical energy auxiliary zincizing technique.
Background technique
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 is then spread from inside to outside simultaneously, whereby, forms one layer of uniform zinc-iron compound, i.e. zincizing on metal works surface layer Layer realizes cathodic protection to metal works by zinc coat.
Currently, the powder zincizing to surface of workpiece is handled, mainly carried out under closed vacuum environment, specifically There is following two ways:
First is that metal works, zinc powder and various penetration-assisting agents are packed into Sealing furnace using Sealing furnace " static state " zincizing, enable Metal works are embedded in compound powder, and after being heated to predetermined technological temperature, held for some time realizes that diffusion type seeps under " static state " Zinc after zincizing terminates, is come out of the stove after cooling to predetermined temperature.
This kind of zincizing mode needs to break a seal to come out of the stove again after treatment due to carrying out filling out furnace seal operation before zincizing, Therefore, treatment process can only be by the mode of furnace processing, and each furnace is required to heat up before treatment in addition, and drops after treatment The whole processing time of temperature, each furnace takes around 6~8 hours, and zincizing processing ineffective time cost is too long, causes at technique Inefficiency is managed, heating, cooling process wastes a large amount of time, the energy and labour.
Second is that using rotary Sherardizing furnace " dynamic " zincizing.Rotary Sherardizing furnace is mainly by support roller, burner hearth ontology, heating unit Part, hermetic rotary zincizing tank, Rolling motor composition;When operation, by metal works, zinc powder, various auxiliary agents, inertia impact media It is fitted into hermetic rotary zincizing tank, then closed zincizing tank lifting is put into burner hearth ontology, and be set up in two sides together On support roller, the rotation of zincizing tank is driven by Rolling motor, while heating to zincizing tank, handle the predetermined time at a predetermined temperature Afterwards, heating element is closed, zincizing tank furnace cooling to predetermined temperature is then turned off Rolling motor and hangs out zincizing tank, finally beats It opens zincizing tank and takes out treated workpiece.When metal works are of large quantities, a large amount of workpiece can also once be dispensed to several zincizings In tank, it will be handled in several zincizing tanks simultaneously lifting to mesh belt transmission formula Sherardizing furnace, 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 reacting for zinc atom and surface of workpiece atom, achieve the effect that mechanical auxiliary seeps, still, is rolled revolving speed by zincizing tank Limited, the kinetic energy of acquisition is small, cannot effectively excite the activation energy of zinc atom, moreover, because needed before zincizing into Row fills out furnace seal operation, needs to break a seal again after treatment to come out of the stove, and therefore, treatment process still can only be by furnace processing, in addition Each furnace is required to heat up before treatment, and cools down after treatment, and the whole processing time of each furnace part is small there is still a need for 5~6 When, it is still limited to improve zincizing efficiency effect in such a way that machinery rotation helps infiltration, it is difficult to meet serialization, extensive The beat requirement of production.
It, 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, since the rotary motion of hermetic rotary zincizing tank is so that it can not realize interior Portion's heating, and can only be the heating element by being set between burner hearth and hermetic rotary zincizing tank, first hermetic rotary is seeped Zinc can is externally heated, then delivers heat to its internal metal works by zincizing tank again, this is resulted in, heating element spoke The heat penetrated can consume a part by flue, cannot fast and effeciently conduct to metal works, extend heating metal works institute The time (while also extending temperature fall time) needed, efficiency is reduced, so that the disposed of in its entirety time of each tank is elongated, meanwhile, Heating and cooling zincizing tank cause energy waste because adding additional the loss of heat again, and increase dirty to the heat of environment Dye.
It follows that existing zincizing technology, zincizing reaction efficiency is lower, and the disposed of in its entirety time is long, and energy consumption is high, also makes At energy waste.
