Molten steel vacuum circulation degassing (RH) technology is a kind of steel secondary refining technique, is to produce high-quality variety steel indispensability
External refining means.RH vacuum refining device is used primarily for liquid steel degassing, and its metallurgy principle is dependent on pressure reduction and is promoted by molten steel
To vacuum chamber, and making Circulating Flow of Molten Steel by blowing argon gas, utilize vacuum environment to reach the purpose of degassing (N2, H2, O2), it is excellent
Point is that response speed is fast, vacuum is high, metallurgical effect is good.
Nearly 20 years, in order to meet the Production requirement of clean steel, various countries' active development multi-function fine sweetening process, vacuum is taken off
The functions such as gas, decarburization, heating, powder injection desulphurization and the cold steel of elimination organically combine, and the vacuum refining forming comprehensive high-efficiency sets
Standby.
RH treatment technology in early days is whole vacuum equipment overhead traveling crane to be hung in ladle molten steel inserted above process, i.e.
" single chamber cage type ", through forms such as " cantilever-rotating lifts ", develops " double flute is portable ", i.e. vacuum tank level at present and moves
The form of dynamic ladle lifting moving.For improving vacuum refining treatment effeciency, dependence improves constantly argon and is blown into flow to increase steel
Liquid recycle stream amount, this makes the splashing of molten steel the most constantly increase, causes the device height of vacuum tank to increase from about the 6m at initial stage
Being added to nearly more than 10m, the requirement to the hall space height processing station is also continuously increased, and certain factory introduces 130tRH dress from external
Standby, equipment installs total absolute altitude+28.000m ,-7.050m, workshop overhead traveling crane rail level absolute altitude+29.600m.Certain factory introduces from external
180tRH equips, and equipment installs total absolute altitude+27.8m ,-6.930m, workshop overhead traveling crane rail level absolute altitude+34.000.Certain factory is domestic
180tRH equips, and equipment installs total absolute altitude+32.130m ,-6.700m, workshop overhead traveling crane rail level absolute altitude+35.000m.Certain factory is domestic
210tRH equips, and equipment installs total absolute altitude+32.965m ,-6.930m, workshop overhead traveling crane rail level absolute altitude+35.000m.
To such an extent as to the old Factory Building that overhead traveling crane rail level absolute altitude is relatively low (certain factory overhead traveling crane rail level absolute altitude+25.000m) the most arranged not under
The equipment of equipment for vacuum refining, haves no alternative but promote factory building height, increases investment, otherwise will affect these steel mills and optimize technique stream
Journey, it is impossible to use RH vacuum refining process to produce high-quality product.
What number of patent application 201010595023.3 was announced " reduces RH vacuum treatment installation under the conditions of low rail level absolute altitude
The method of setting height(from bottom) " although RH can be reduced to a certain extent equip setting height(from bottom), but the reduction of middle absolute altitude is very limited, still
Being actually needed of most of short Factory Building can not be met, and directly reduce vacuum tank height 700～800mm, vacuum will be caused
Groove and hot-bending pipe dross increase the weight of.It is therefore desirable to study some new equipment and technologies, to reach total installed height mark is greatly reduced
