Technical field
The present invention relates to railway cast steel wheel production technical field, and in particular to a kind of railway cast steel wheel V method graphite swashs
Cold gravity foundry technology.
Background technology
The technique that domestic production railway cast steel wheel is poured into a mould using the moulding and rising pouring bag of graphite mould hanging sand lining at present, in
Entreat rising head to concentrate feeding, can be achieved again to the consecutive solidification of wheel hub from wheel rim to disc, and wheel rim dense structure, its technique into
Ripe, product quality is stable.But graphite mould institute hanging sand lining be water-glass sand, average monolithic wheel consumes quartz sand in 90kg or so,
Calculated according to 250,000 wheels are produced per year, nearly 2.25 ten thousand tons of quartz sand of year consumption, the scale of construction is quite huge.
In the long term, quartz sand is non-renewable resources, and high-quality quartz sand source is increasingly reduced, and price will climb year by year
Rise, the increase of wheel manufacturing cost can be caused.Particularly, limited by current water-glass sand regeneration techniques, a large amount of antiquated sands are outdoor
Storage, the ecological environment on periphery will be had a strong impact on, and restrict the bottleneck of Sustainable Development of Enterprises.
The content of the invention
It is an object of the invention to provide a kind of railway cast steel wheel V methods graphite Quench gravity foundry technology, solves tradition
Water-glass sand recovery utilization rate is low in railway cast steel wheel production technology, and a large amount of antiquated sand discharges influence periphery Ecological environment
Problem.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of railway cast steel wheel V methods graphite Quench gravity foundry technology, is to have merged V methods foundry engieering and graphite Quench work
The drag box of skill, the cope for getting out be equipped with the upper graphite annulus of shaping and the lower graphite annulus for being equipped with shaping, using V methods
Required mo(u)ld top half and mo(u)ld bottom half are respectively prepared using cope and drag box for formative technology, and made of mo(u)ld bottom half placement resin sand
SMIS, it is made drench with rain core and floating core of resin sand in mo(u)ld top half placement, after mo(u)ld top half and mo(u)ld bottom half mould assembling under the negative pressure state of setting, adopts
Poured with rising pouring bag and outpour wheel.
As present invention further optimization, mo(u)ld top half and mo(u)ld bottom half, upper graphite annulus and lower graphite are made using V method formative technologies
Ring is located at the lateral surface of corresponding rim for automobile wheel, and dead head is arranged on mo(u)ld top half and corresponded to above wheel hub.
As present invention further optimization, poured into a mould using rising pouring bag, during cast molten steel through dead head, floating core, drench with rain core
Small cast gate injects die cavity, fills type to when setting riser height when molten steel, cast terminates, and floats core and floats, the core center feeding that drenches with rain is led to
Road is opened, and is emitted intraoral molten steel and is persistently carried out feeding, rim for automobile wheel fast rapid hardening in the presence of graphite annulus Quench to wheel body
Gu forming the tissue of densification, while in the presence of central dead head, realize that the order again to wheel hub from wheel rim to disc is coagulated
Gu after feeding terminates, rising head is pulled out along the core that drenches with rain while outputing mo(u)ld top half, then takes wheel, sandbox pressure release, knockout, antiquated sand warp
It is online to recycle after magnetic separation, dedusting, cooling, it is also online to recycle after graphite annulus forces cooling.
Compared with prior art, the present invention can at least reach one in following beneficial effect：
1. for V methods casting technique at home using mature and stable, its advantage is that moulding quartz sand need not add binding agent, is followed
Ring utilization rate can effectively solve water-glass sand regeneration and recovery profit in traditional railway cast steel wheel casting technique up to more than 95%
With rate it is low the problem of, greatly reduce the consumption of quartz sand and the discharge of antiquated sand, control beneficial to wheel manufacturing cost and subtract
Few influence to ecological environment.
2. graphite chilling block technique at home using maturation, its advantage is that the big chill effect of graphite heat conducting coefficient is good, by
Mo(u)ld top half and mo(u)ld bottom half correspond to rim for automobile wheel lateral surface and set upper graphite annulus and lower graphite annulus, effect of the rim for automobile wheel in graphite annulus Quench
Lower quick solidification, forms the tissue of densification, while in the presence of central dead head, realize and arrive wheel hub again from wheel rim to disc
Consecutive solidification.
