Scrapping of part, heavy then cannot organize and effectively produce.Molten stainless steel secondary oxidation is solved under using original equipment premise
Problem, it is necessary in melting, casting process, by its smelting furnace, casting ladle and the shell that need to pour into a mould, forms the one of local one by one
Individual noble gas vacuum chamber, thus reach to prevent or alleviate the purpose of molten stainless steel secondary oxidation.
Summary of the invention
In order to solve the problems referred to above, the present invention provides melting and the casting forming method of a kind of stainless steel material, effectively
Solve a molten stainless steel secondary oxidation difficult problem, it is ensured that produce qualified stainless cast steel part.
The melting of a kind of stainless steel material and casting forming method, increase in melting and cast conventional equipment and fill for argon
Put, during the melting and moulding by casting of stainless steel material, be passed through argon, whole at crucible, shell and casting ladle of protection aluminium alloy
From air oxidation during individual melting and moulding by casting:
1) material melting: be placed in melting kettle by material, first leads to argon with ring-type for argon device, then starts crucible
Heating, starts to end from melting, and ring-type confession argon device constantly blows out argon and whole crucible covers into independent argon vacuum
Room;
2) proceed to casting ladle: after melting terminates, aluminium alloy is poured into before casting ladle 1~3 minute, by tubulose blowing for argon device
Argon pipe passes to casting ladle bottom depths, at aluminium alloy during casting ladle poured into by intermediate frequency furnace, adds argon continuously, along with pouring in casting ladle
Alloy liquid level constantly rises, and synchronizes to supply tubulose Argon Guan Shangyi of argon device;
3) moulding by casting: will pour into a mould first 1~3 minute, tubulose is deep for the Argon Guan Fangzhi shell interior of argon device
Place, at aluminium alloy during casting ladle pours shell into, adds argon continuously, along with the alloy liquid level poured in shell constantly rises, with
Walk Argon Guan Shangyi of tubulose argon device, until completing material moulding by casting.
Wherein, ring-type for argon device, including for argon ring, argon blowing hole, caudal peduncle, argon bottle, the band of gas, it is ring-type sky for argon ring
Heart metal tube, for circular argon blowing hole along ring Zhou Junbu is distributed on argon ring, caudal peduncle is hollow pole, and one end communicates with for argon ring
And be welded on for argon ring side, the other end is connected with the band of gas of argon bottle, is placed on crucible top for argon ring in the middle of fusion process,
Opening argon bottle switch, argon is blown out by argon blowing hole and covers whole crucible.Tubulose is for argon device, including Argon pipe, argon
Bottle, the band of gas, Argon pipe is hollow tubular structure, and one end is connected with the band of gas of argon bottle, and the other end is argon gas export.
The invention has the beneficial effects as follows, can effectively control the secondary oxidation of stainless steel alloy liquid in intermediate frequency furnace, produce conjunction
The stainless cast steel part of lattice, overcomes the defects such as the pit of cast(ing) surface appearance, black speck.
