Description
Technical field
The utility model belongs to apparatus for melting metal field, specifically, relates to a kind of Metal Melting with slipping steel tank.
Background technology
Melting, is that metal material and other auxiliary material are put into heating furnace and dissolved and quenched, and furnace charge is in high temperature (1300～1600K)
In stove there is certain physics, chemical change, output crude metal or metal enrichment thing and the pyrometallurgical processes of slag in material.Stove
Material, in addition to concentrate, calcining, sintering deposit etc., the most also needs to be added to make furnace charge to be prone to melted flux, and anti-for carrying out certain
Answer and add reducing agent.Crude metal or metal enrichment thing are that two-layer is able to due to the least with molten slag mutual solubility of density differential
Separate.Enriched substance has sulfonium, speiss etc., and they need process through blowing or additive method just can obtain metal.
Vacuum melting is the Metal Melting carried out in vacuum melting furnace, is often passed through inert gas equilibrium air pressure in smelting furnace, existing very
Empty melting typically utilizes electromagnetic induction heating.
The steel tank that slips is no matter at common metal fusion process, or all serves the effect of fortune metallic solution of slipping in Vacuum Melting；
Traditional steel tank that slips mainly forms with clay or other refractory materials, and is to use one-shot forming technique manufacture, traditional steel that slips
Groove just produces bigger defect at the initial stage of manufacture: internal stress is big, there is matched moulds seam, and structure is insecure；Traditional steel tank that slips makes
Being affected by high temperature during with and be susceptible to fragmentation, its top layer is easily stripped, and inwall kish is not easily cleaned, and slips fortune metal
Solution processes easily make metal (mainly high temperature alloy) be contaminated in fusion process；Further, since tradition slips steel tank
Structure is single, uses expendable mo(u)ld shaping, and its degree second-rate, resistant to elevated temperatures is relatively low, thus makes in the middle of reality application
Metal (the mainly precious metal such as high temperature alloy etc.) quality that melting produces is affected；And if needing to improve and slip steel tank
Quality and high temperature resistant degree, then need to improve manufacturing cost, causes putting into the rough sledding close to even greater than output and occurs, because of
And tradition slip steel tank be badly in need of improve in structure and technique；It addition, traditional steel tank that slips cannot be used for vacuum melting technique,
Under vacuum melting technique, the life-span is low, easily produces metallic solution and pollutes.
Chinese Patent Application No. 91106040.5, the patent application document in publication date on August 7th, 1991, disclose a kind of metallurgical
The molten steel runner made of aluminium-carbon composition with low cement content of stove.It uses alumine or corundum material, then is equipped with a certain amount of silicon powder, alumina cement
Or pure calcium aluminate cement, pitch or graphite are raw material, mix thoroughly with water and water reducer, pre-formed in pouring into mould, make after heat treatment
For finished product.What this patent application remained that oil immersion is cut bulk flow steel tank in vain builds feature by laying bricks or stones, do not change steel mill technical management code and
The operation property of operating personnel, is not required to any professional equipment, installs simple, nonhazardous gas discharge, longevity in tapping process
Life is long, low cost, is a kind of preferably metallurgical furnace flume it can also be used to ladle brick goods.This patent application publication
Technical scheme uses a cast molding, although material component is made that improvement, but it is big still to there is internal stress, there is matched moulds
Seam, structure is insecure, is affected by high temperature and is susceptible to fragmentation, and its top layer is easily stripped, and inwall kish is not easily cleaned
Defect.
Chinese Patent Application No. 201110173466.8, the patent application document in publication date on November 16th, 2011, disclose one
Planting flume device, described flume includes: molten steel chute, ash pit, slag-drip opening, upper slag trap, lower slag trap；Wherein,
Slag-drip opening is positioned at the top of ash pit, and upper slag trap is positioned at the downstream of ash pit, and lower slag trap is positioned at the upstream of ash pit；
Wherein, in described flume device: alloy solution is together injected in ash pit together with the slag produced in smelting process,
On described under the effect of slag trap and lower slag trap, smelt slag and be blocked in ash pit, and the alloy solution formed is rapid
Dynamic the least.By the enforcement of this invention, the scum silica frost of molten steel can be got rid of, and remove the Large Inclusions in alloy solution, make amorphous
Carry pours into a mould more direct motion continuously, improves the quality of amorphous ribbon.But the technical scheme of this patent application publication is the most fundamentally
Solve its quality and the problem of structure existence, affected by high temperature the most serious.
